Product Spotlight: Jinfiniti, wellness at a cellular level

We're careful about what we put on the shelves at Areté. The retail wall is small on purpose, every product on it is something a member of the team uses, has read the studies on, and would honestly recommend to a friend. So when a new line shows up here, it has been through a real test. Jinfiniti is the most recent one to make it through, and I want to be straight about what we found and who I think it's actually for.

What Jinfiniti is

Jinfiniti is a longevity-focused supplement company built around NAD+ optimization, that is, raising and stabilizing the levels of nicotinamide adenine dinucleotide in your cells. NAD+ is a coenzyme involved in essentially every energy-producing pathway in the body. Levels decline with age, and a lot of what we experience as "getting older", slower recovery, foggier mornings, less metabolic flexibility, tracks closely with that decline.

Their flagship is the Accuri Vitality Boost, an NMN-based formula that the body converts into NAD+. They also offer the Accuri Test Kit, a finger-prick assay that measures your intracellular NAD+ levels, so you're not guessing whether the supplement is doing anything.

What "cellular wellness" actually feels like

This is the question that matters. Supplements that promise everything usually deliver nothing perceptible. Here's what we actually noticed across six months of consistent use across the team:

• Mornings start faster. The grogginess between alarm and the first cup of coffee got shorter for most of us. Not dramatically, but consistently.
• Recovery from training is better. Soreness clears about a day faster. This is the most measurable change we tracked.
• Energy is steadier. Less of the 3 p.m. crater. No jitter.
• Sleep felt deeper for a few of us, though that effect was the most variable across the team.

And, importantly, most of us didn't feel dramatically different on a day-to-day basis. The change shows up in retrospect. Two months in, you realize you're not as sore. Four months in, you realize the morning fog is gone.

The testing piece is the difference

Most NAD+ companies sell you a bottle and hope. Jinfiniti sells you the bottle and the test. We measured baseline before starting and again at twelve weeks. Every team member's intracellular NAD+ went up, the smallest increase was 28%, the largest 71%. That's not a placebo argument. That's an actual measurement.

If you only do one of the two, the test is honestly the more interesting product. Knowing your number gives you a target. It lets you stop guessing.

Who it's for

• People over 35 who feel like recovery is slower than it used to be.
• Athletes layering training with sauna, plunge, and float.
• Anyone already eating well, sleeping well, and moving regularly who wants to optimize the next layer down.

Who it isn't for

• Anyone hoping a supplement will fix poor sleep, a sedentary week, or chronic stress. It won't. Foundations first.
• People who want a noticeable, immediate kick. This isn't caffeine.
• Anyone with active cancer or undergoing chemotherapy, talk to your oncologist before starting any NAD+ precursor.
• Pregnancy or breastfeeding, skip it.

How we use it at Areté

We've started recommending Jinfiniti to members who are already in a rhythm, floating regularly, plunging, getting into the sauna, who are looking for the next dial to turn. It pairs especially well with the recovery practices we're already built around. The clinical reasoning lines up: NAD+ is central to the same mitochondrial repair pathways that cold and heat exposure activate. They're complementary stresses on the same system.

Jinfiniti is on the shelf in our retail space alongside the test kits. Members get a small discount. If you want to talk through whether it's the right fit before you commit, ask any of us at the front desk, we'll give you the same honest read we gave each other.
