- Is oral NAD+ absorbed?
- Poorly. NAD+ is a large molecule that is broken down in the digestive tract, which is why researchers often study precursors like NR and NMN instead. Cellvia adds quercetin and resveratrol, but that does not fix absorption of the NAD+ itself.
- How long does one bottle last?
- The label lists 30 servings, so one bottle covers about a month at the stated dose. Check the serving size on the panel to confirm how many capsules a day that means.
- Is it vegan and gluten-free?
- Yes. Cellvia lists the product as vegan, vegetarian, gluten-free and corn-free, which suits most restricted diets. Anyone with other allergies should still read the full ingredient list.
- NAD+ or NMN — which should I buy?
- NMN and NR are precursors with more human absorption research behind them. NAD+ capsules like this one are a newer, less studied option, so compare doses and third-party test certificates before choosing.
- When is the price lowest?
- Supplement prices often dip during sitewide sales and subscribe-and-save signups. No price was supplied for this listing, so check the current store price and its history before buying.
