A single-ingredient NMN supplement: 500 mg of nicotinamide mononucleotide per serving, taken as two veggie capsules once a day. 60 capsules per bottle, a 30-day supply. Non-GMO, gluten-free, made and shipped in the USA.

The precursor your cells use to make NAD+, the coenzyme they run on to turn food into usable energy and to run their repair pathways. NMN occurs naturally in foods like edamame, broccoli and avocado in milligram amounts; the human research uses hundreds of milligrams a day.

So you can see exactly what you are taking and at what dose. No proprietary blend, no fillers doing the label's work, nothing to look up.

Yes. Each batch is tested by an independent ISO 17025 accredited lab for identity, potency, heavy metals and microbials. The most recent certificate measured 533 mg of NMN per serving against the 500 mg on the label, with heavy metals and microbials all passing.

The capsules are veggie capsules, no gelatin. The formula is gluten-free and non-GMO. For the full ingredient panel, see the supplement facts image on the product page.

No. Nothing in Perennial is a stimulant, which is also why there is no jolt and no crash.

NAD+ starts declining well before 40, and Perennial is formulated for adults 18 and over. Most of the people who write to us are in their 40s to 60s, because that is when the afternoon wall usually shows up.

Two veggie capsules once a day, taken together, ideally in the morning. Consistency over weeks matters more than exact timing.

Either. If your stomach is sensitive, take it with breakfast.

Yes. NMN has no known interaction with caffeine.

Two veggie capsules carry practically no calories, so it fits inside a fasting window.

Take it the next morning as usual. Don't double up.

No. It is designed for daily use. The human trials ran it daily for 8 to 12 weeks without breaks.

We recommend swallowing them whole with water.

Give it the full 60 days of the guarantee, taken daily. Many people describe a steadier afternoon within the first few weeks, and the effect builds with consistent use.

Not a jolt. It works in the background, so people tend to describe the change as an absence: the wall that used to arrive at three arrives later, or doesn't.

In human trials, oral NMN raises blood NAD+ in a dose-dependent way, and one NIH-funded trial found improved muscle insulin sensitivity. Those are the findings. The studies are listed and linked on the product page, including where the evidence stops.

Perennial supports the body's own NAD+ production. It is not intended to diagnose, treat, cure, or prevent any disease, and we don't make claims about specific conditions.
