Built on three principles. Held to one standard.
01
Clinical Dosing
Every ingredient is dosed at the level shown to work in published research — not the cheapest level to include.
1,000mg NMN
5g creatine
1,000mg L-Carnitine
02
Full-Formula Testing
We don’t just trust data on individual ingredients. We test the entire blend — the way you actually drink it.
Every batch is independently tested.
Every COA (test result) is published.
03
Versioned, Not Fixed
Our formulas have version numbers because they keep changing. When the science moves, we move.
OneFit is on v4.6.
OneLife Science is on v2.1.
Two formulas. Same obsession.
OneFit®
For how you perform
31-in-1 recovery blend
One serve replaces protein, creatine, electrolytes, carnitine, and multi-vitamins. 31 research-backed ingredients, one per-day serve. No stacking, no guesswork, no shelf full of jars.

OneLife®
For how you age
1,000mg NMN + 1,000mg Resveratrol
The full longevity protocol — in one daily sachet. Replaces NMN, resveratrol, CoQ10, and the rest of the longevity stack with one clinical formula.

The same broken solution.
OneFit® Science
After hard training, your body has a 30-minute window to start repairing. Most people miss it.
The standard fix is a stack: protein here, electrolytes there, creatine on the side. Underdosed, expensive, and almost always incomplete. We built OneFit because recovery shouldn’t be an afterthought.

OneLife® Science
By your 40s, your NAD+ levels have already dropped by up to 50%. Most people don’t know. Fewer do anything about it.
NAD+ is the molecule your cells depend on for energy production, DNA repair, and healthy ageing. It declines sharply from your 30s onward — and most NMN products deliver a fraction of what research actually uses. OneLife delivers 1,000mg of NMN per serve: the clinically studied dose, not a token inclusion.

How every formula
is made.
Five stages. Same process for OneFit and OneLife Science.
Stage 01:
Research
We start with the published evidence, not the trending ingredient.
Every ingredient in our formulas earns its place through clinical data. We start by asking “what does the research say works?” and build a shortlist based on proven doses, proven mechanisms, and proven safety. If it’s only popular on Instagram, it doesn’t make it in.
Stage 02:
Formulation
We dose at the level the research used. Then we make sure everything works together.
Underdosing is the supplement industry’s favourite trick. We dose at the clinically effective amount — 5g of creatine, 1,000mg of NMN, 1,000mg of L-Carnitine — and engineer the blend so absorption, taste, and stability all hold up.
Stage 03:
Testing
Every batch goes to an independent lab.
We test for purity, dosage accuracy, heavy metals, and microbial safety — every batch, not just occasionally. Independent of us. Then we publish the certificate of analysis (COA), because if you have to ask for it, that’s a problem.
Stage 04:
Iteration
If new science changes the answer, we change the formula.
OneFit is on version 4.6. OneLife Science is on version 2.1. That’s 304 formulation iterations between them. Each one driven by published research, customer outcomes, or third-party data we couldn’t ignore. Most supplement brands launch a formula and never touch it again. We do the opposite.
Stage 05:
Publication
What we find, you see.
Every COA, every clinical study we run, every formula change — published openly. You shouldn’t have to take our word for any of it.
Every benefit. Every dose. Every reason.
Tap any benefit for the full breakdown — what we use, why we use it, and the dose the research supports.
Hydrolysed Collagen Protein — 25g
What? We wanted a highly effective, fast-absorbing, and gut-friendly protein source that maximised muscle recovery and strength while also offering additional benefits beyond muscle repair.
We chose Hydrolysed Collagen Protein because it has been clinically studied to enhance lean muscle mass, strength, and joint health while being easier to digest and free from bloating issues. Unlike other proteins, which can spike insulin and cause inflammation in some individuals, hydrolysed protein works with the body’s natural repair processes to improve both performance and longevity.
Why This Dose? We include 25g per serving, optimized for muscle protein synthesis (MPS), the process your body uses to repair and build stronger muscles after training. This amount ensures your muscles get enough high-quality protein to kickstart recovery without excess fillers.
OneFit uses hydrolysed collagen protein, clinically shown to increase lean mass, strength, and connective tissue repair. Since Hydrolysed Protein is lower in leucine, we added BCAAs (2:1:1 per serve) to compliment MPS activation, while delivering better digestion, reduced inflammation, and superior joint support.
Muscle-building power plus smarter recovery with OneFit.
Magnesium Citrate — 1.25g
Sodium Chloride — 0.64g
Potassium Citrate — 0.39g
Hydration is essential for muscle recovery, helping transport nutrients, flush out waste, and prevent cramping. After training, electrolyte loss can slow muscle repair and reduce performance, so we included a full-spectrum electrolyte blend to replenish what’s lost, prevent cramps, and support nerve signalling.
We included Magnesium Citrate (1.25g), Sodium Chloride (0.64g), Potassium Citrate (0.39g), and Calcium to restore electrolyte balance, improve muscle contractions, and support nerve signaling. Magnesium and potassium reduce cramping and muscle fatigue, while sodium and calcium help retain fluids and optimize muscle function. Together, they ensure hydration supports—not limits—your recovery.
Many electrolyte formulas under-dose key minerals or overload sodium, leading to imbalanced hydration and poor absorption. Our precise blend mirrors what’s lost in sweat, providing just enough sodium for fluid retention without bloating, enough magnesium and potassium to prevent muscle fatigue, and calcium to maintain muscle function. Combined with creatine for cellular hydration and probiotics for better absorption, this ensures faster recovery, improved endurance, and hydration that actually works.
Micronised Creatine Monohydrate — 5g
Creatine is the most researched performance supplement in history, proven to increase strength, boost endurance, and speed up recovery by fuelling ATP production, the body’s primary energy source for movement.
We use Micronised Creatine Monohydrate (now at 5g per serve)—the gold standard backed by 1,000+ studies. It’s the most effective, bioavailable, and well-studied form, shown to enhance power, build lean muscle, and fight fatigue with long-term safety.
5g per serve is the clinically proven amount to fully saturate muscles, maximize strength and endurance, and eliminate the need for a loading phase. It’s the simplest, most effective way to get all the benefits—without the guesswork.
Women naturally have 20–30% lower creatine stores than men, making supplementation even more impactful. 5g per day boosts strength, endurance, and recovery, while also supporting brain function, hormone balance, and muscle preservation—especially as estrogen declines with age. No bloating, just science-backed benefits for performance and long-term health.
L-Carnitine — 1000mg
Fat metabolism isn’t just about appearance, it’s about performance, longevity, and joint health.
Excess fat increases strain on joints, impacts endurance, and slows recovery. We included L-Carnitine at 1000mg per serve to help transport fat into mitochondria, where it’s burned for energy instead of stored.
L-Carnitine is clinically shown to enhance fat oxidation, improve endurance, and reduce post-exercise fatigue. It also plays a role in reducing inflammation and supporting brain function, making it a key ingredient for both athletes and active individuals.
1000mg per serve is the clinically effective amount to maximize fat utilization, enhance metabolic efficiency, and support sustained energy levels, ensuring fat is used as fuel while protecting lean muscle.
Vitamin C, Vitamin D3, Zinc, and Curcumin
Recovery isn’t just about muscles, it’s about keeping your immune system strong so your body can fight off stress, inflammation, and illness. Intense training can weaken immunity, increasing the risk of colds, fatigue, and slower recovery times. OneFit includes key immune-supporting ingredients to keep you performing at your best.
OneFit includes Vitamin C, Vitamin D3, Zinc, and Curcumin, each clinically shown to strengthen immune defences, reduce inflammation, and support recovery. Vitamin C enhances white blood cell function, improving the body’s ability to fight infections. Vitamin D3 regulates immune response and has been linked to a lower risk of respiratory infections. Zinc plays a crucial role in immune cell production and has been shown to reduce the duration of colds. Curcumin, derived from turmeric, is a powerful natural anti-inflammatory that helps reduce stress on the immune system after intense training.
Each ingredient is dosed for maximum effectiveness.
Creatine, Collagen, Probiotics, Antioxidants
Gut and brain health are connected. When your gut is strong, your brain performs better—clearer thinking, better focus, and more energy. OneFit is designed to support both with key ingredients at the right doses.
The gut houses trillions of bacteria, influencing everything from nutrient absorption to neurotransmitter production (like serotonin and dopamine). A well-balanced gut microbiome leads to better digestion, improved immune response, and sharper mental performance.
Creatine is best known for muscle power, but just as effective for the brain. Creatine enhances ATP production in brain cells, improving focus, reaction time, and mental endurance. It also protects against cognitive decline.
Collagen strengthens the gut lining, reducing inflammation and improving digestion.
Probiotics introduce good bacteria, supports digestion, immune health, and mental clarity by reducing inflammation and optimizing nutrient absorption.
Antioxidants fight oxidative stress in both the gut and brain. Zinc supports gut barrier integrity and cognitive function, while Vitamin C helps reduce inflammation linked to brain fog.

Questions
worth asking.
Most supplement brands formulate once, then defend that formula for years — reformulating costs money, and admitting an earlier version could be better doesn't make for a clean launch story. We take the opposite position. Every active in a First or Nothing protocol is reviewed against current research, sourcing, and dosing data on an ongoing basis. When the evidence moves, the formula moves with it. That's not inconsistency — it's the standard.
NMN is one of the most actively studied compounds in the longevity space. Research to date shows NMN supplementation can raise NAD+ levels, and early human studies point to potential support for energy metabolism and markers of healthy ageing. It's one of the most credible, well-researched compounds available right now, and OneLife is dosed at the levels used in that research - not the token amounts some "NMN" products use just to get the ingredient on the label.
We take the extra measure most brands skip: every batch is checked against its certificate of analysis by an independent lab before it ships, confirming potency and purity match what's written on the panel. That's not a courtesy line - testing costs money, and most customers never ask, which is exactly why most brands don't bother. We'd rather you ask.
Single ingredients are easy to market and hard to use well. A standalone NMN capsule, for example, still needs the right supporting actives around it to actually do its job — most people don't realise that until they're three single-ingredient bottles deep. We compound multiple research-backed actives into one all-in-one protocol, dosed at the levels used in the research behind them. The trade-off we're optimising for isn't the simplest ingredient list — it's the simplest way to actually take what works.
We highly recommend 90 days of consistent use for both products. OneFit is built around daily performance — protein, creatine, electrolytes, gut health — and most people do notice a shift in energy and recovery within the first one to two weeks of consistent use, but don't reap full benefits until 3+ months. OneLife works differently and needs time. NMN and NAD+-linked actives have a cumulative effect: the benefit builds with consistent daily use rather than showing up week to week. We recommend a minimum of 90 days of consistent use before assessing whether OneLife is working for you — that's the timeframe the ingredients need to do their job, not a marketing minimum.
This is the question most supplement labels are hoping you don't ask. A lot of products include a "hero" ingredient at a fraction of the dose used in the studies that made it famous - enough to put it on the panel, not enough to do much. We formulate to the doses actually used in the research behind each active. If a dose can't meet that bar, it doesn't go in the protocol.
Yes — they're designed to complement each other, not compete. OneFit covers daily performance: protein, creatine, electrolytes, recovery. OneLife covers longevity: NMN-supported cellular health and cognitive function. The two protocols don't duplicate actives, so there's no overlap to manage. If you want both covered without running two separate subscriptions, the Comprehensive Bundle runs them side by side at a lower per-day cost than buying separately.
We don't ask you to take label claims on faith. Every protocol is tested against its certificate of analysis by an independent lab, and that documentation is available below.
