DoNotAge Sachet Review: All 15 Ingredients, Dosages, and Research Doses Compared

15 ingredients, $203/month, one daily sachet. I broke down every compound, cross-referenced the dosages against published research, and flagged what's underdosed.

I've been buying DoNotAge supplements individually for about a year now. NMN, TMG, resveratrol, the usual Sinclair-adjacent stack. When they launched the daily longevity sachet in April 2026, my first reaction wasn't excitement. It was suspicion. All-in-one products tend to underdose everything so they can slap a long ingredient list on the label.

So I went through each of the 15 compounds, pulled the dosages from DoNotAge's standalone products, and compared them against what published research actually uses. Some of the numbers surprised me. A few didn't.

What's inside the DoNotAge daily sachet?

The DoNotAge sachet organizes its 15 longevity ingredients into six biological pathway systems. That framing comes from a YouTube video DoNotAge released at launch. I'll walk through each system and what it does, but the short version: the ingredients aren't random. They're grouped by how they interact inside your cells.

NAD+ energy and DNA repair (5 ingredients)

Five compounds make up this core. NMN converts into NAD+, which your cells burn for energy and repair. Resveratrol and the SIRT6 Activator act as the engines that use that NAD+ to fix DNA damage and manage metabolism. TMG and Ca-AKG prevent the methylation crash that happens when NMN ramps up your cellular machinery.

The standalone NMN product delivers 500 mg per capsule (two capsules, so 1 g/day). Research doses for NMN in human trials range from 250 mg to 1,000 mg. TMG standalone is also 1 g/day. Resveratrol is 1 g/day of pure trans-resveratrol. Ca-AKG is 500 mg. SIRT6 Activator is their proprietary seaweed-derived compound with no public dosage info.

Whether the sachet matches these standalone doses is the open question. I don't have the supplement facts label yet. I've asked for it.

Cellular cleanup: autophagy and senolytics (4 ingredients)

Four ingredients handle autophagy (recycling damaged cells) and senolysis (killing zombie senescent cells). Spermidine triggers autophagy. Quercetin and fisetin are senolytics that clear out cells that have stopped dividing but refuse to die. SulforaBoost (sulforaphane) activates your body's internal antioxidant pathways through the Nrf2 system.

Standalone spermidine is 8 mg/serving. Published research typically uses 1 to 6 mg, so DoNotAge actually exceeds most trial doses on that one. Quercetin standalone is 400 mg, on the lower end of the 500 to 1,000 mg range used in senolytic research. Fisetin is around 100 mg. Research protocols for senolytic dosing often go much higher (up to 500 mg), though those are usually intermittent "hit and clear" protocols rather than daily use.

Vascular and structural support (3+ ingredients)

The remaining compounds handle delivery and structural function. Vitamin D3 (5,000 IU in the standalone product), K2 (120 mcg as MK-7), and Magnesium (250 mg as L-Threonate) form a dependency triad. D3 needs magnesium to activate. K2 directs the calcium that D3 helps absorb into your bones instead of your arteries. CoQ10 supports mitochondrial function in the heart and blood vessels. Nitralis is DoNotAge's proprietary nitric oxide booster, clinically shown to increase NO production by 226%.

The D3 and Magnesium doses are where I'd push back on the sachet.

DoNotAge sachet ingredient dosages vs. research doses

Remaining ingredients (likely Apigenin at $47 and one or two more) bring the individual total past $730.

Where the DoNotAge sachet dosages fall short

Two compounds are probably underdosed for someone optimizing rather than maintaining.

Vitamin D3 at 5,000 IU is fine as a standalone capsule dose. If the sachet contains a fraction of that (to fit 15 ingredients into a powder), you could be getting 1,000 IU or less. The government RDA of 600 IU is almost universally considered too low by longevity researchers. Most recommend 4,000 to 10,000 IU daily, targeting serum levels of 60 to 80 ng/mL.

Magnesium L-Threonate at 250 mg sounds reasonable until you realize the elemental magnesium yield from the threonate salt is only about 48 mg. The male RDA is 420 mg elemental. Even the standalone product delivers roughly 11% of the RDA. Threonate was chosen for its ability to cross the blood-brain barrier, not for its elemental magnesium content.

NMN bioavailability is the other conversation. The sachet doesn't specify liposomal encapsulation, and oral NMN does undergo significant metabolism in the gut. Published human trials show oral NMN raises NAD+ levels. DoNotAge's own trial showed a 76% increase. Saying it has "zero availability" without liposomal delivery is wrong. Liposomal forms are measurably more efficient, though.

DoNotAge sachet cost vs. buying individually

Buying all 15 ingredients individually from DoNotAge's own store runs about $685 per 28-day cycle. The sachet is $203. That's a 70% savings. I itemized every product and the numbers check out.

The caveat: cost savings doesn't mean dose equivalence. You might be getting a lower dose of each ingredient in the sachet compared to the standalone capsule. That's the tradeoff with any all-in-one longevity formulation.

My take on the DoNotAge longevity sachet

The sachet is a solid base layer for someone who doesn't want to manage 15 bottles. The ingredient selection is genuinely thoughtful. The six-system framing makes biochemical sense. The cost savings are real.

If you're optimizing aggressively, I'd use the sachet as your foundation and add extra D3 (3,000 to 5,000 IU) and extra magnesium (200 to 300 mg of glycinate or threonate) on top. That covers the gaps without adding much cost.

I'll update this article with exact per-ingredient sachet doses once I have the supplement facts label. My 30-day NAD+ lab results are coming soon too.
