What Is OneFit?®

OneFit® is your complete daily formula for performance, recovery, and everyday wellness. One sachet or scoop. One habit. Everything your body needs covered.

How Does OneFit® Compare To Whey?

Whey protein only gives you protein. That's it. You're still missing vitamins, minerals, greens, and everything else your body needs.

OneFit gives you the complete picture in one scoop. You get quality protein plus everything else for training, recovery, and daily performance. No more buying five different products.

No more guessing if you're covering all your bases. One habit. Everything covered. It's what protein powder should have been from the start.

Can I Take OneFit On Rest Days?

Yes — OneFit is designed as a daily habit, not just a workout supplement. Your body still needs nutrition on rest days to recover, rebuild, and stay energised.

Will OneFit Cause Bloating?

No. OneFit is formulated specifically so you don't feel like garbage after drinking it. You know that bloated, heavy, sick feeling you get from other protein powders?

That's gone. One customer told us OneFit is the only protein she's ever had that doesn't make her feel sick and bloated.

If you've written off supplements because they wreck your stomach, OneFit changes that. You drink it, you feel good, you get on with your day.

How do i take it?

One serve into ~200ml of cold water. Stir. Done in 60 seconds. Best taken first thing in the morning on an empty stomach.

What is NMN?

NMN (Nicotinamide Mononucleotide) is the direct precursor to NAD+ — the molecule your cells need for energy production, DNA repair, and healthy aging. Harvard researcher Dr. David Sinclair called it "the closest thing we have to a fountain of youth." Problem is, your NAD+ levels drop by 50% by age 50. OneLife delivers 1,000mg of 99.8% pure NMN daily to restore what you're losing.

When will I feel results?

Days 1-15: Energy and mental clarity improve. The fog lifts.

Days 15-60: Sleep quality and recovery noticeably better.

Days 60-90: The compound effect kicks in — this is where cellular transformation accelerates.

Most people feel something in the first week. The real shift happens when you commit to 90 days.

Can I take it with coffee?

Yes. Take OneLife first thing on an empty stomach. Coffee after is fine — we've removed Guarana from the formula, so there's no caffeine stacking to think about. The L-Theanine is still there, supporting calm, steady focus alongside your normal coffee.

What's the difference between OneFit and OneLife?

OneFit is your daily all-in-one performance blend. It replaces your protein, creatine, collagen, magnesium, electrolytes, and 16 vitamins and minerals in a single serve.

OneLife is our NMN longevity formula, designed to support cellular energy, recovery, and long-term healthspan.

Many of our customers start with OneFit and OneLife as part of their complete health routine.

Can I take OneFit and OneLife together?

Yes, they're designed to work together. OneFit covers your daily performance nutrition. OneLife supports cellular health and longevity from a completely different angle.

Together, they're the full FON routine. Most customers take OneFit in the morning and OneLife with breakfast. Ease into it to avoid minor GI discomfort.

Is it worth the price?

OneFit replaces five of those for a fraction of that cost. When you factor in what you're no longer buying, most customers actually spend less with FON than they did before.

What is NMN?

NMN (Nicotinamide Mononucleotide) is the direct precursor to NAD+ — the molecule your cells need for energy production, DNA repair, and healthy aging. Harvard researcher Dr. David Sinclair called it "the closest thing we have to a fountain of youth." Problem is, your NAD+ levels drop by 50% by age 50. OneLife delivers 1,000mg of 99.8% pure NMN daily to restore what you're losing.

I didn't have to guess for weeks. Within the first few days I noticed cleaner energy and better bounce-back after activity. That early signal gave me confidence to keep going and the visible changes followed.

— Sarah M.
★ ★ ★ ★ ★

Replaced my entire supplement drawer.

I was spending close to 200 a month on NMN, magnesium, CoQ10, and ashwagandha separately. Switched to OneLife three months ago and I'm getting better doses of everything in one hit for less money. Should've done it sooner.

— Mark D. (44)

I'm usually the person who gets bloated or uncomfortable with supplements. OneFit has been easy to digest from day one. No heaviness, no gut issues which honestly surprised me and made it easy to stay consistent.

— Daniel K.
★ ★ ★ ★ ★

Actually look forward to it in the morning.

Not going to lie, I expected it to taste like grass. It doesn't. Mixed it with cold water, honestly tastes like a light juice. My wife tried it and now she's on the Duo plan. That says enough.

— Chris R. (51)
★ ★ ★ ★ ★

Before OneFit I was using protein, creatine, electrolytes, and a couple of extras. I'd miss days because it was annoying. OneFit replaced that whole routine with one sachet. I'm actually more consistent now and that's where the results came from.

— Emily T.
★ ★ ★ ★ ★

Week two, the brain fog lifted.

First few days I didn't notice much. By week two I was waking up before my alarm and actually feeling sharp by 8am. Sleep's deeper too I'm not waking up at 3am anymore. Three months in now and I'm not going back.

— Lisa T. (58)
★ ★ ★ ★ ★

Some weeks I train hard. Some weeks it's just walks or light movement. OneFit still makes sense either way. It's not about smashing workouts it's about supporting your body after you move. That flexibility is a big reason I've kept using it.

— Michael L.
★ ★ ★ ★ ★

4 a day. Better than anything I've tried at triple the price.

Came from IM8 was paying over 180 a month for capsules and honestly couldn't tell if they were doing anything. OneLife is cheaper, I can actually feel the difference, and it's one sachet instead of a handful of pills. No contest.

I'm skeptical by default. I read labels and look for testing. OneFit was clear about what's in it and why. The dosing made sense, the testing was there, and it didn't feel like a throw everything in formula. That transparency is what earned my trust.

My skin is the thing that surprised me most.

I started taking it for energy and focus the perimenopause fog was getting unbearable. Got that within a few weeks. But by month two, people started commenting on my skin. My aesthetician asked what I'd changed. That's when I knew it wasn't placebo.

I didn't believe it. Now I've auto-renewed twice.

I'm the guy who thinks most supplements are expensive urine. Bought OneLife expecting to claim the refund. By week three I was sleeping through the night for the first time in years. By week six my wife said I seemed like a different person. I've now renewed twice and I don't see that stopping.

Threw out 7 bottles. Kept one sachet.

My bathroom cabinet looked like a pharmacy. NMN, resveratrol, magnesium, CoQ10, ashwagandha, fish oil, a multivitamin. Seven bottles, 250+ a month, and I'd forget half of them anyway. OneLife replaced all but the fish oil. One sachet. Done. My wallet and my countertop have never been cleaner.

Started it for myself. Now my husband steals mine.

I bought the single plan in November. By December my husband kept asking for a sip of mine every morning. We switched to the Duo in January. It's become our morning thing two sachets, two glasses, out the door. Cheaper than our old coffee order too.

I travel 3 weeks a month. This is the only supplement that comes with me.

Capsules get forgotten. Powders need a scoop and a shaker. The sachet format is genuinely the reason I've stuck with this for 4 months. Tear, pour, stir, done. Airports, hotels, offices doesn't matter. If it wasn't this easy I wouldn't still be taking it.

AG1 was hundreds a month for a greens powder. This actually does something.

I took AG1 for a year. Honestly couldn't tell you what it did other than make my pee green. Switched to OneLife because of the NMN and resveratrol actual ingredients with actual clinical doses. Felt the difference within two weeks. Wish I'd switched sooner.

I used to wake up every night at 3am. That stopped in week two.

I didn't buy this for sleep. I bought it for energy. But the first thing I noticed was I stopped waking up at 3am. Then I stopped needing a coffee before 10. Then my wife asked if I'd been working out because my face looked different. Three things changed from one sachet. Not bad.

My GP asked what I'd changed. Showed her the blood panel.

Had routine bloods done at month two. Inflammation markers down, vitamin D up, cortisol in range for the first time in three years. My GP asked what I'd changed. I showed her the sachet. She said keep doing whatever you're doing. That was good enough for me.

Tastes better than my pre-workout and it actually does more.

I've drunk some horrible supplement concoctions over the years. This isn't one of them. Mixed with cold water it genuinely tastes fine; light, slightly citrusy, no chalky aftertaste. My pre-workout tastes worse and costs more. This was a non-issue.

I want to be there for my kids' weddings. Not just there, present.

I'm 46 with a 6-year-old and a 3-year-old. I don't have the luxury of slowing down. Started OneLife because I want to be sharp and active when they're adults, not just alive. Four months in and I have more energy for them now than I did two years ago. That's all that matters.

FON FAQ

What's the difference between OneFit and OneLife?

OneFit is your daily all-in-one performance blend. It replaces your protein, creatine, collagen, magnesium, electrolytes, and 16 vitamins and minerals in a single serve.

OneLife is our NMN longevity formula, designed to support cellular energy, recovery, and long-term healthspan.

Many of our customers start with OneFit and OneLife as part of their complete health routine.

I already take protein and creatine. Why would I switch?

OneFit contains clinical doses of both, plus collagen, electrolytes, and vitamins you're probably buying separately.

Most customers switch from 5-7 products and save over $150/month. Same ingredients, fewer tubs, one routine that actually sticks.

I don't train hard. Is OneFit still for me?

Absolutely. OneFit isn't just for athletes. The collagen, b-vitamins, creatine, and electrolytes support energy, skin health, gut health, and daily recovery whether you train 7 days a week or just want to feel better with one simple habit each morning.

How do I know your NMN is real?

Every batch of OneLife is third-party tested for purity and potency, and we publish the results. 64% of NMN products tested on Amazon contained less than 1% of what was on the label. We exist because that's unacceptable. You can view our testing certificates on the OneLife product page.

What does it taste like?

OneFit comes in Choc, Vanilla or Trop Crush. It's designed to taste good mixed with just water, no blender needed. If you're unsure, our promise guarantee allows you to swap flavours anytime

How long before I notice results?

With OneFit, most customers notice improved energy and recovery within the first 1 week.

OneLife works at the cellular level, so expect sustained energy, better sleep quality, and improved mental clarity within 2-3 weeks of consistent daily use.

This isn't a stimulant. It's compounding.

Is it worth the price?

The average supplement user spends $190-310/month across multiple products.

OneFit replaces five of those for a fraction of that cost. When you factor in what you're no longer buying, most customers actually spend less with FON than they did before.

Can I take OneFit and OneLife together?

Yes, they're designed to work together. OneFit covers your daily performance nutrition. OneLife supports cellular health and longevity from a completely different angle.

Together, they're the full FON routine. Most customers take OneFit in the morning and OneLife with breakfast. Ease into it to avoid minor GI discomfort.
