What makes this different

Built for dads, not gym bros

The first supplement designed around broken sleep, chronic stress, and the specific ways fatherhood drains you.

No stimulants, no crash

Our AM formula supports energy and focus without caffeine. No 3pm wall.

Pharmacy-grade, hyper-clean

Every batch independently tested for pesticides, heavy metals, and contaminants. Nothing you wouldn't want in your body.

Every ingredient earns its place

21 evidence-based ingredients across AM and PM, backed by 70+ peer-reviewed studies. No fillers, no proprietary blends, no token doses.

Foundation, not a shortcut

This isn't a replacement for sleep or diet. It's the nutritional framework that helps your body do what it's supposed to when fatherhood won't let it.

Made in the UK

Manufactured to GMP standards in a UK-licensed facility.

NRV = Nutrient Reference Value. — indicates no NRV established.

Food supplements should not be used as a substitute for a varied and balanced diet and healthy lifestyle. Do not exceed the recommended daily dose. Keep out of reach of young children. Store in a cool, dry place.

AM: Sustained mental energy without the crash or jitters. Stress resilience through adaptogenic support. Sharper focus during the demands of the day. Immune and metabolic support from D3, B vitamins and BioPerine.

PM: Better sleep quality, even when hours are limited. Natural melatonin support through precursors, not synthetic melatonin. Nervous system recovery and evening calm. Mineral replenishment for what chronic stress burns through fastest.

When we surveyed 337 fathers, "evidence it actually works" was the number one thing they wanted from a supplement. So we built this formula around it. Every one of our 21 ingredients is supported by peer-reviewed research. Over 70 studies in total, including randomised controlled trials published in PubMed-indexed journals.

Key actives are dosed at therapeutic levels, not token amounts: L-Theanine at 400mg total daily, Rhodiola at 200mg (standardised extract), L-Tryptophan at 220mg, and CoQ10 at 100mg. Every vitamin and mineral form is chosen for bioavailability: methylcobalamin not cyanocobalamin, P5P not pyridoxine, zinc picolinate not oxide, 5-MTHF not folic acid.

The Problem

Broken sleep. Chronic stress.
Your body is burning through resources faster than you can rebuild.

Fatherhood doesn't just make you tired. It changes how your body produces energy, handles stress and recovers overnight. And passing out at 11pm isn't the same as sleeping.

A typical father's night. Fragmented sleep architecture.

The Depletion Cycle

It's not one problem.
It's a cascade. Each stage makes
the next one worse.

This is why "just eat better" or "just sleep more" doesn't cut it. You're fighting a system, not a symptom.

01

Fragmented Sleep

Deep recovery phases get cut short. Every. Single. Night.

02

Cortisol Stays Elevated

Your stress hormone never fully resets. You wake already in fight-or-flight.

03

Nutrients Burn Faster

Chronic stress accelerates depletion of key minerals and B vitamins. Diet alone can't keep pace.

04

Fog, Crashes, Short Fuse

Running low on raw materials by midday. Crashing by 3pm. Snapping by bedtime.

Fog, Crashes, Short Fuse

Running low on raw materials by midday. Crashing by 3pm. Snapping by bedtime

You're not failing as a father.
Your biology is running on depleted resources.

Good Dad addresses this at every stage of the cycle, not just the symptoms at the end.

Your Journey

What to expect when
you start rebuilding.

This isn't a magic pill. Some ingredients work within hours. Others build over weeks. Here's what to expect.

Days 1 to 3 You are here

A Quieter Baseline

Less mental noise. A calmer starting point. L-Theanine works within 30 to 45 minutes. Rhodiola begins levelling your cortisol. The PM formula helps you fall asleep faster.

Weeks 2 to 4

Sleep Starts Shifting

You start waking up feeling closer to rested. The PM formula reshapes sleep quality, not just duration. The AM adaptogens build, and the afternoon crash starts fading.

Month 2+

Your New Baseline

The 3pm wall fades. You stop running on empty. This isn't a peak you have to maintain. It's a baseline you've restored.

A note on honesty: Individual results vary. Some ingredients are at full therapeutic doses. Others provide concentrated adaptogenic support. We tell you which is which.

Your journey with Good Dad supplements
Full Transparency

Every ingredient. Every dose.

No proprietary blends. No hidden formulas. 21 ingredients across two targeted formulas. Here's exactly what's inside and why.

🌿
Rhodiola Rosea
200mg · standardised extract
Why it's here
Modulates your cortisol response. When sleep is fragmented, cortisol stays elevated. Rhodiola helps bring it down so you can stay calm under pressure instead of snapping.
✓ Therapeutic dose
Form & standardisation
3% rosavins, 1% salidrosides - the exact standardisation used in clinical research. Not a generic powder.
🍄
Lion's Mane
2000mg · 10:1 fruiting body
Why it's here
Supports nerve growth factor (NGF) production - the protein that helps your brain maintain and repair neural connections. Fights the brain fog.
Concentrated extract
The honest note
200mg of 10:1 extract (≈ 2000mg raw). Clinical studies typically use 1000-3000mg of extract. This is adaptogenic support, not a full clinical dose. The 10:1 concentration means it's working harder than most.
🍄
Cordyceps
800mg · 4:1 fruiting body
Why it's here
Supports oxygen utilisation and cellular energy production. Helps you sustain energy through the day without stimulants.
Concentrated extract
The honest note
200mg of 4:1 extract (≈ 800mg raw). Provides concentrated adaptogenic support for endurance and vitality.
N-Acetyl-L-Tyrosine
200mg · NALT
Why it's here
Precursor to dopamine and norepinephrine. The neurotransmitters behind focus, motivation and mental drive. Most effective under stress and sleep deprivation.
Supportive dose
Form advantage
N-Acetyl form crosses the blood-brain barrier more effectively than standard L-Tyrosine. Better bioavailability where it matters.
🍵
L-Theanine
150mg · from decaffeinated green tea
Why it's here
Promotes alpha brain waves for calm focus. Reduces mental chatter within 30 to 45 minutes. 400mg total daily is the dose used in clinical research.
✓ 400mg daily · therapeutic
Decaf natural source
Extracted from decaffeinated green tea, not synthesised. No caffeine or stimulants added. Natural source for better integration with your body's chemistry.
🔋
Coenzyme Q10
100mg · ubiquinone
Why it's here
Your cells' power supply. Levels decline with age and chronic stress, which is why tired dads feel it so much. 100mg is the established clinical threshold.
✓ Therapeutic dose
What it does
Supports cellular energy at the most fundamental level. You can't feel energised if your cells can't produce energy efficiently.
☀️
Vitamin D3
25µg · 500% NRV
Why it's here
Immune function, bone health, mood support. Most UK adults are deficient, particularly in winter months. Paired with K2 for proper calcium absorption.
Appropriate dose
Synergy
D3 + K2 MK-7 together ensure calcium goes to your bones, not your arteries. They need each other.
🦴
Vitamin K2
100µg · MK-7 · 133% NRV
Why it's here
Directs calcium to bones and teeth, away from soft tissue. Essential partner to D3. MK-7 form has the longest half-life for sustained benefit.
Appropriate dose
Form advantage
Menaquinone-7 (MK-7) - the most bioavailable form. Stays active in your body for up to 72 hours vs 4-6 hours for MK-4.
🧠
Vitamin B6
4.5mg · P5P active form · 321% NRV
Why it's here
Your brain needs B6 to make serotonin, dopamine, and GABA. Active P5P form your body uses directly. Contributes to the reduction of tiredness and fatigue.*
Appropriate dose
Form advantage
Pyridoxal-5-Phosphate (P5P) - the active form your body uses directly. Cheap supplements use pyridoxine, which your liver has to convert first.
🧬
Folate (B9)
400µg · 5-MTHF · 200% NRV
Why it's here
Supports cell repair and methylation. 5-MTHF is the body-ready form. Up to 40% of people can't properly convert standard folic acid. We skip the problem entirely.
Appropriate dose
Form matters
5-MTHF (methylfolate). The natural, body-ready form. ~40% of people have MTHFR gene variants that make converting synthetic folic acid difficult. We skip the problem entirely.
Vitamin B12
250µg · methylcobalamin
Why it's here
Energy metabolism, nervous system function, red blood cell formation. Deficiency shows up as fatigue, brain fog and mood changes.
Appropriate dose
Form advantage
Methylcobalamin - body-ready, no conversion needed. Cheap brands use cyanocobalamin (contains a cyanide molecule your body has to remove first).
🌶️
BioPerine®
2.5mg · black pepper extract
Why it's here
Makes every other ingredient in the formula absorb better. Clinically shown to increase bioavailability significantly. The multiplier.
✓ Absorption enhancer
The multiplier
Patented BioPerine® - not generic black pepper. Standardised to 95% piperine. Makes every other ingredient work harder.
Energy & Focus
Sustained energy without the crash
Supports normal energy metabolism and cognitive function throughout the day.*
Stress Resilience
Handle the chaos, keep your patience
Adaptogens and B vitamins support normal psychological function under pressure.*
Immune Support
D3, mushroom extracts and B vitamins
D3, mushroom extracts and B vitamins contribute to normal immune system function.*
🍒
Tart Cherry
4000mg · 10:1 Montmorency
Why it's here
Helps your body produce its own melatonin naturally. No synthetic version, no dependency, no rebound. Just better sleep onset and overnight recovery.
✓ Near-clinical dose
The honest note
400mg of 10:1 extract (≈ 4000mg raw Montmorency cherry). Clinical studies use 480-500mg powder - we're close to that range with a concentrated extract.
🍵
L-Theanine
250mg · from decaffeinated green tea
Why it's here
Promotes alpha brain waves associated with relaxation without drowsiness. Helps quiet the mental loop of to-do lists and worries that keeps you awake.
✓ 400mg total daily · clinical
Split dosing strategy
150mg AM + 250mg PM = 400mg daily. Higher PM dose supports sleep onset; lower AM dose supports calm focus without drowsiness.
🌱
Lemon Balm
1000mg · 4:1 leaf extract
Why it's here
Takes the edge off the evening without knocking you out. GABA-enhancing herb used for centuries for restlessness. Modern research backs the traditional use.
✓ Near-clinical dose
The honest note
250mg of 4:1 extract (≈ 1000mg raw). Cyracos® studies use 300-600mg extract - we're near the lower clinical threshold.
😴
L-Tryptophan
220mg · UK maximum
Why it's here
The raw material your body uses to make serotonin and melatonin. Without it, the sleep cascade can't start. 220mg is the maximum the UK allows.
✓ At UK regulatory max
Regulatory context
220mg is the maximum permitted dose in UK supplements. Clinical studies use 250mg-1g. We've maxed what regulation allows.
🛡️
Zinc
15mg · picolinate · 150% NRV
Why it's here
Immune function, testosterone support, cognitive function and cell protection. One of the first minerals depleted by stress and poor sleep.
Appropriate dose
Form advantage
Zinc picolinate - significantly better absorbed than the cheap oxide or gluconate forms most brands use. In the PM formula because zinc is best absorbed in the evening.
🫚
Ginger Root
500mg · 10:1 extract · 5% gingerols
Why it's here
Settles your stomach so the PM capsules sit comfortably. Anti-inflammatory support that also helps the other ingredients absorb properly.
Concentrated extract
Extract potency
50mg of 10:1 extract (≈ 500mg raw), standardised to 5% gingerols for consistent active compound delivery.
🌼
Chamomile Flower
400mg · 10:1 extract
Why it's here
Contains apigenin, which binds to GABA receptors to promote relaxation and sleep onset. Gentle, well-established, no grogginess the next morning.
Concentrated extract
Traditional & modern
40mg of 10:1 extract (≈ 400mg raw). Used for centuries as a calming tea. Modern research confirms the mechanism - apigenin acting on benzodiazepine-like receptors.
🧠
Vitamin B6
4.5mg · P5P active form · 321% NRV
Why it's here
B6 is essential for converting tryptophan to serotonin to melatonin. The sleep cascade depends on it. Without adequate B6, tryptophan can't do its job.
Appropriate dose
AM + PM synergy
Present in both formulas because it supports different pathways at different times: neurotransmitter production (AM) and sleep hormone synthesis (PM).
⚖️
Copper
1mg · bisglycinate · 100% NRV
Why it's here
Maintains copper-zinc balance, which matters when you supplement zinc. Without it, high zinc intake can deplete copper over time. Small dose, important job.
Balance dose
Form advantage
Bisglycinate chelate - gentle on the stomach and highly absorbable. Cheap brands use copper oxide or sulphate which can cause irritation.
Sleep Quality
Better sleep, even when it's broken
Supports natural sleep processes and recovery during fragmented nights.*
Evening Calm
Quiet the mental to-do list
Supports normal nervous system function and psychological relaxation before bed.*
Overnight Recovery
Wake up closer to yourself
Contributes to the reduction of tiredness and fatigue, supporting overnight repair.*
HPMC vegetarian capsules. No fillers, no bulking agents, no artificial colours. 2 capsules per formula, 4 daily total.

400mg daily sits at the upper end of the clinical range (200-400mg). Split dosing across AM and PM provides sustained benefits throughout the day. Clinical range: 200-400mg daily

  • Williams JL, et al. (2020) -Systematic Review PMID: 31758301

    Confirmed 200-400mg daily for up to 8 weeks is safe and effective for stress and anxiety management.

  • Hidese S, et al. (2019) -RCT PMC6836118

    200mg/day for 4 weeks: significant improvements in depression (p=0.019), anxiety (p=0.006), and sleep quality (p=0.013).

    28-day supplementation reduced Perceived Stress Scale by 17.98% (p=0.04).

  • Unno K, et al. (2021) -Mechanistic PMC8475422

    Single 200mg dose increased frontal alpha brain wave power -the signature of relaxed alertness.

  • Meta-analysis (2024) -11 Studies PMC11616108

    Cross-country analysis found L-theanine significantly reduced psychiatric symptoms as adjunct therapy.

200mg sits at the lower end of the clinical range (200-600mg) but matches the standardised WS 1375 extract used in positive trials. Clinical range: 200-600mg standardised extract

  • Lekomtseva Y, et al. (2017) -RCT, 100 subjects PMID: 28219059

    2x200mg WS 1375 for 8 weeks: greatest improvement after just 1 week, with continued benefits throughout the trial.

  • Ishaque S, et al. (2012) -Systematic Review PMID: 22643043

    Review of 11 studies found evidence supporting benefits for physical performance and mental fatigue, though results were contradictory across studies.

  • Darbinyan V, et al. -Multiple SHR-5 trials

    288-680mg daily for 2-6 weeks: improved mood, cognitive performance, and attention in fatigued individuals.

100mg is the lower end of the clinical range (100-400mg). Optimal may be 300mg+ per some reviews, but meaningful fatigue reduction is seen from 100mg. Clinical range: 100-400mg daily · Optimal: 300-400mg per systematic review

  • Mehrabani S, et al. (2022) -Meta-analysis, 13 RCTs PMID: 36091835

    1,126 participants: CoQ10 significantly reduced fatigue (p=0.001). Dose-response coefficient: -0.0017 per mg.

  • Mortensen SA, et al. (2014) -Q-SYMBIO Trial PMID: 25282031

    420 patients, 100mg 3x/day for 2 years: reduced major adverse cardiovascular events.

  • Mehrabani S, et al. (2019) -Systematic Review, 16 studies PMID: 30935528

    10 of 16 studies showed significant beneficial effects on fatigue (p<0.05) across healthy, statin-related, and chronic fatigue populations.

200mg at 10:1 concentration is equivalent to ~2,000mg raw mushroom. Clinical trials typically use 1,000-3,000mg extract, placing this in the supportive range. Clinical range: 1,000-3,000mg extract · Our equivalent: ~2,000mg raw

  • Docherty S, et al. (2023) -RCT, 41 adults PMC10675414

    1.8g for 28 days: faster cognitive task performance (p=0.005); trend toward reduced stress (p=0.051).

  • Mori K, et al. (2009) -RCT PMID: 18844328

    3g/day for 16 weeks: significantly improved cognitive function in mild cognitive impairment.

  • Systematic Review (2024) -26 studies PMC12434001

    Confirmed neuroprotective, antioxidant properties; erinacines and hericenones stimulate NGF biosynthesis.

200mg at 4:1 concentration is equivalent to ~800mg raw. Clinical trials use 1,000-4,000mg. Included as part of an adaptogenic complex, not a standalone dose. Clinical range: 1,000-4,000mg · Our equivalent: ~800mg raw

  • Hirsch KR, et al. (2017) -RCT PMC5236007

    4g/day for 3 weeks: improved VO2max (+4.8, p=0.042) and time to exhaustion.

  • Chen S, et al. (2010) -RCT PMC3110835

    333mg 3x/day for 12 weeks: metabolic threshold increased 10.5% (p<0.02).

  • Ontawong A, et al. (2024) -RCT PMID: 38580687

    8-week supplementation: increased NK cell activity in both men and women.

Clinical studies typically use 300-500mg or weight-based doses (100-150mg/kg). 200mg provides precursor support but is below most studied doses. Typical clinical range: 300-500mg · Acute stress studies: 100-150mg/kg body weight

  • Jongkees BJ, et al. (2015) -Review PMID: 26424423

    Tyrosine supplementation most beneficial when neurotransmitter function is intact but limited by availability.

  • Neri DF, et al. (1995) -Sleep deprivation study PMID: 7794222

    150mg/kg during sleep deprivation: significantly improved psychomotor performance and reduced vigilance lapses for ~3 hours.

  • Colzato LS, et al. (2013) -Rapid Evidence Assessment PMID: 26126245

    14 controlled trials: supported recommendation for tyrosine to mitigate cognitive decline during stressor exposure.

1000 IU is a maintenance dose appropriate for general supplementation. Higher doses (3,000-4,000 IU) show stronger testosterone effects but require monitoring. Supplementation range: 1,000-4,000 IU · Testosterone evidence: inconclusive

  • Pilz S, et al. (2011) -RCT PMID: 21154195

    3,332 IU/day for 1 year in deficient men: total testosterone increased from 10.7 to 13.4 nmol/L (p<0.001).

  • Grant WB, et al. (2025) -Evidence Review PMID: 39861407

    Serum levels >30 ng/mL significantly lower disease and mortality risks. 2,000 IU/day prevents deficiency; ~60% of Northern Europeans are insufficient.

  • Meta-analysis (2024) -17 trials PMC11506788

    17 trials: Vitamin D supplementation significantly increased total testosterone (p=0.03). Strongest effects in deficient populations.

  • Hartmann E, et al. (1979) PMID: 469515

    250mg -the dose closest to ours -significantly increased Stage IV (deep) sleep in mild insomniacs.

  • Meta-analysis (2021) PMID: 33942088

    Tryptophan supplementation shortened wake-after-sleep-onset by 81 minutes per gram (p=0.017).

250mg PM + 150mg AM = 400mg daily total. The PM portion is the larger dose, deliberately weighted toward evening for sleep-quality support. See AM formula for full study citations.

400mg at 10:1 concentration = ~4,000mg raw cherry. Clinical studies use 480-500mg powder or 30-60ml concentrate. Evidence is moderate with some conflicting results. Clinical range: 480-500mg powder · Our equivalent: ~4,000mg raw

  • Howatson G, et al. (2012) -RCT PMID: 22038497

    30ml concentrate 2x/day for 7 days: significant increases in sleep time and efficiency (p<0.05) with elevated urinary melatonin.

  • Losso JN, et al. (2018) -Pilot study PMC5617749

    Increased sleep time and efficiency. Proposed mechanism: procyanidin B-2 inhibits IDO, increasing tryptophan availability for melatonin.

  • Hillman AR, et al. (2022) PMID: 35790450

    44 participants over 30 days: no significant differences vs placebo. Methodological differences may explain discrepancy.

250mg at 4:1 concentration = ~1,000mg raw. Clinical studies use 300-600mg standardised extract (Cyracos). We're slightly below the clinical floor for standardised extracts. Clinical range: 300-600mg Cyracos · Our equivalent: ~1,000mg raw

  • Meta-analysis (2021) PMID: 34449930

    Significantly improved anxiety (SMD: -0.98, p=0.003) and depression (SMD: -0.47, p=0.0005) vs placebo.

  • Bano S, et al. (2023) -RCT PMC10620697

    400mg/day for 3 weeks: significant improvements in depression, anxiety, stress, and quality of life (all p<0.001).

  • Cases J, et al. (2011) -Pilot trial PMC3230760

    600mg/day Cyracos for 15 days: significantly reduced anxiety-related symptoms in mild-moderate anxiety.

15mg is the standard NRV-level dose. Clinical testosterone studies often use 30-50mg elemental zinc. Our dose maintains zinc status; clinical effects on testosterone depend on baseline deficiency. Clinical range: 15-50mg elemental · Testosterone effect depends on baseline zinc status

  • Systematic Review (2022) -38 papers PMID: 36577241

    Confirmed zinc deficiency reduces testosterone; supplementation improves levels. Effects vary by basal zinc status.

  • Prasad AS, et al. (1996) PMID: 8875519

    Older men with marginal zinc deficiency: doubled testosterone levels with 6-month supplementation.

  • Jazinaki MS, et al. (2024) -Systematic Review, 8 RCTs PMID: 39377022

    Majority of evidence showed significant improvement in sleep quality with zinc supplementation vs control groups.

40mg at 10:1 = ~400mg raw. Clinical studies use 200-400mg extract or 400-800mg powder. We're at the lower end of extract range -supportive rather than standalone. Clinical range: 200-400mg extract · Our equivalent: ~400mg raw

  • Meta-analysis (2024) -10 studies PMID: 39106912

    772 participants: significant PSQI reduction (-1.88); improved night awakenings but no improvement in sleep duration.

  • Adib-Hajbaghery M, et al. (2017) -RCT, 60 participants PMID: 29154054

    200mg extract 2x/day for 28 days: significantly improved sleep quality vs placebo. Concluded chamomile is a safe modality for promoting sleep.

50mg at 10:1 = ~500mg raw with 5% gingerols. Clinical studies use 250mg-1.5g powder. Included primarily for digestive comfort and anti-inflammatory support. Clinical range: 250mg-1.5g powder · Our equivalent: ~500mg raw

  • Marx W, et al. (2023) -RCT, 103 participants

    84mg/day active gingerols: lower incidence of delayed nausea at Cycle 2 (53% vs 75%, p=0.020).

  • Ernst E, Pittler MH (2000) -Systematic Review PMID: 10793599

    6 RCTs: ginger superior to placebo for seasickness (p<0.05) and morning sickness (p=0.035).

A note on honesty. Not every ingredient in this formula is at a full clinical dose. We think you deserve to know that. Ingredients like Lion's Mane and Cordyceps are included as concentrated adaptogenic extracts at meaningful levels, while L-Theanine, Rhodiola, L-Tryptophan and CoQ10 are dosed at or near therapeutic ranges. Where studies conflict, we show them. That's the standard we hold ourselves to.

12 AM ingredients for energy, focus and stress resilience. 9 PM ingredients for deep, restorative sleep. 21 total. Every ingredient and exact dose is published on the product page and on the label. No proprietary blends, nothing hidden. Scroll up to the full ingredient breakdown to see everything.

Most multivitamins use token doses of generic ingredients. Good Dad uses therapeutic or near-clinical doses of actives chosen specifically for broken sleep, stress, energy depletion and cognitive load. The AM/PM split means energising ingredients in the morning and sleep-supportive ingredients in the evening. A single daily multivitamin can't do that.

Because your body needs different support at different times. Rhodiola and CoQ10 belong in the morning. Tart Cherry and L-Tryptophan belong in the evening. Combining them into one dose means the energising ingredients keep you awake, or the calming ones make you drowsy at work. The split avoids that entirely.

Some are, some aren't, and we tell you which is which. L-Theanine, Rhodiola, CoQ10 and L-Tryptophan are at or near therapeutic doses. Lion's Mane and Cordyceps are concentrated extracts at supportive levels. Every ingredient is labelled "Therapeutic", "Near-clinical", "Concentrated extract", "Supportive" or "NRV appropriate". We haven't seen another brand do this.

Good Dad uses well-researched, food-grade ingredients at published doses. If you're on prescription medication, particularly blood thinners, SSRIs, or blood pressure medication, check with your GP first. Every ingredient and dose is published so your doctor can make a quick, informed call.

Good Dad replaces your multivitamin, not sits alongside it. Taking both could exceed recommended intakes for B vitamins, Vitamin D and Zinc. The AM formula covers your essential micronutrients alongside the targeted performance ingredients.

Yes. No minimum commitment, no cancellation fees, no questions. You can pause, skip or cancel from your account dashboard whenever you want. If you cancel during the Founding Father period, your locked-in pricing cannot be restored if you resubscribe later.

Sleep improvements often show within the first week. The AM formula builds over time. Adaptogens like Rhodiola need 2 to 4 weeks, and full stress-resilience benefits emerge around 6 to 8 weeks. We recommend 60 days before judging the full picture.

Our first 500 customers lock in a permanently discounted rate as a thank-you for backing us early. The price stays the same even when we raise it later. Once the 500 spots fill, this pricing disappears. All purchase options (subscription, 90-day and one-time) include Founding Father pricing.

Good Dad is in the final stages of manufacturing. Pre-orders ship June 2026. Full payment is taken at checkout to secure your order and lock in Founding Father pricing. Subscriptions renew from the date of your first shipment, not the date you ordered.

Yes. If you're not satisfied within 30 days of receiving your first order, full refund. No hoops, no return shipping costs. We're confident in what we've built and we want you to try it without risk.

Yes. GMP-certified UK facility. Every batch independently tested for purity, potency and heavy metals. Free from artificial colours, flavours, GMOs, gluten, soy and dairy. HPMC capsules, suitable for vegetarians and vegans.
