Five longevity ingredients. One formula.
Most NAD+ products rely on a single ingredient. Otium combines an NAD+ precursor with four synergistic compounds studied for cellular health.
Nicotinamide Riboside
A well-researched NAD+ precursor that helps support your body's natural NAD+ levels — central to cellular energy metabolism.
TMG (Trimethylglycine)
Supports methylation — an often-overlooked companion to NAD+ precursors that helps maintain metabolic balance.
Resveratrol
A plant-based polyphenol with antioxidant properties, widely studied in the context of healthy aging.
Quercetin
A flavonoid antioxidant that helps support cellular health and complements the NAD+ pathway.
Urolithin A
A next-generation compound researched for its role in supporting mitochondrial renewal and cellular vitality.
What's in every serving

Why NAD+ matters as you age
NAD+ is a coenzyme found in every cell, essential for converting food into energy (ATP). Levels naturally decline with age — Otium is designed to help support them.
Replenish
Nicotinamide Riboside provides the raw material your cells use to help maintain healthy NAD+ levels.
Support
TMG supports methylation while Resveratrol and Quercetin add antioxidant support for overall cellular health.

Noticeably steady energy
"The capsules are easy to take and haven't upset my stomach. What I've noticed most is a little more steady energy throughout the day and better focus when I'm working. I picked this because the formula looks more complete than a lot of the other options."

Solid choice for daily energy
"The capsules are very easy to swallow, and there's absolutely no aftertaste. I've definitely noticed a difference in my energy levels — not a harsh, jittery stimulant, just a bit more sustained drive. GMP-certified and made in the USA gives me a lot of confidence."

Well-designed approach to NAD+ support
"Many NAD+ products focus on a single ingredient, whereas this takes a more comprehensive approach — combining an NAD+ precursor with compounds discussed in mitochondrial and healthy-aging research. I appreciate the inclusion of TMG, which is often overlooked."
