OneLife™ is a daily longevity blend: 1g of 99.8% pure NMN and 1g of resveratrol alongside CoQ10, ashwagandha, electrolytes and MCT oil — 17 clinical ingredients in one drink, made in Australia.
NMN (nicotinamide mononucleotide) is the direct precursor to NAD+, the molecule your cells use for energy production, DNA repair and healthy ageing. NAD+ drops by about half by age 50; OneLife™ delivers 1,000mg of 99.8% pure NMN daily to restore what you are losing.
Days 1–15: energy and mental clarity improve. Days 15–60: sleep quality and recovery are noticeably better. Days 60–90: the compound effect builds. Most people feel something in the first week — the real shift comes from committing to 90 days.
One serve into cold water, stirred, in about sixty seconds. Best first thing in the morning on an empty stomach. Coffee afterwards is fine.

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.
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.
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.
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 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'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.
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.
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.
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.
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 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.
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.
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'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.
Most longevity products target one benefit. OneLife targets thirteen. In one daily serve.

Here’s everything you need to know.
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.
Because they work together. NMN boosts NAD+ levels. Resveratrol activates the sirtuins (longevity genes) that USE that NAD+. Taking NMN alone is like filling a fuel tank with no engine. Taking both is how you actually switch the system on. Most brands sell them separately. We combined them — 1g of each — in one serve.
Absorption. Resveratrol and CoQ10 are fat-soluble — without fats, they pass straight through you. MCT Oil Powder acts as a carrier, escorting these compounds into your bloodstream where they actually work. Competitors skip this. That's why people "don't feel anything" from their supplements.
Light, refreshing watermelon. Not chalky. Not "supplement-y." We spent months on flavour because if you hate taking it, you won't stick to the protocol. Most people actually look forward to it.
One sachet into cold water. Stir. Done in 60 seconds. Best taken first thing in the morning on an empty stomach. No blender. No clumping. No excuses.
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.
Because that's what the science demands. NAD+ restoration isn't instant. Cellular repair takes time. The people who "try for 30 days" and quit are stopping right before the compounding benefits hit. The 90-day protocol exists because it works — not because we want your money longer.
That's less than your morning coffee. And unlike coffee, OneLife™ doesn't crash at 3pm. It contains Guarana (clean, sustained energy) plus 16 other actives for cellular health, hydration, focus, and recovery. You're not adding a cost — you're replacing a worse habit with a better one.
Check your dose. Most capsules are 250-500mg. Clinical studies showing real results use 1,000mg. If you're taking less, you're probably underdosed. If you're taking multiple capsules to hit 1g, you're overpaying and missing the synergistic benefits of Resveratrol, CoQ10, and the rest of the stack.
Yes. Take OneLife™ first thing on an empty stomach. Coffee after is fine. Though many people find they need less coffee — or none — once the Guarana and L-Theanine kick in.
Yes. Every batch is third-party tested in Australia for purity, potency, and contaminants. Free from dairy, gluten, soy, nuts, artificial colours, fillers, and gums. Used daily by athletes, founders, and high performers who can't afford to put garbage in their bodies.
Full refund. No questions. No hassle. Email care@usefon.com or DM us on Instagram. If you don't feel sharper, clearer, and more energised — we give you every dollar back. The only risk is staying the same.
No lock-in. No tricks. Just better value for committing to the protocol.
Every batch of First or Nothing products is independently tested for heavy metals, purity, and dosage accuracy to ensure safety and quality.
