Most supplements are built to sell. Ours are built to work — and rebuilt every time the science says we can do better.

What’s Inside (And Why It’s There)

Choose Your Formula

Built on three principles. Held to one standard.

Bottle with checkmark icon 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

Test tube with checkmark icon 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.

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® Science

Person training, with REPAIR 30min recovery window badge

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

Couple holding OneLife, NAD+ 50% decline badge

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.

Lab researcher reviewing published evidence
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.

Researcher formulating a dose in the lab
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.

Lab equipment used for batch testing
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.

Powder ingredients being measured for a new iteration
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.

Person reviewing published lab results on a laptop
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.

The same team.
From research to
your sachet.

From ideation through testing, flavour refinement, and ongoing revision — the same scientists, nutritionists, and researchers stay with the formula. That continuity is how we navigate the conflicting science of nutrition without getting lost in it.

“I want to be able to have an impact on people. With FON, It’s about looking at the bioavailability of everything, how it all combines together […] what the format of each ingredient is, how much is going to be absorbed.”

Questions
worth asking.

Box of OneFit sachets with shaker bottle

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.
