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@befirstornothing.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.
