The publication states that it compared products using publicly available product listings, ingredient panels and verified customer reviews. Each product was scored on six weighted factors: delivery and bioavailability (25%), NAD+ source and dose (20%), third-party testing (20%), ingredient synergy (15%), taste and daily use (10%) and value per serving (10%).
Sunny Within Longevity received an overall score of 4.9 out of 5.0. Its category scores were 4.9 for delivery and bioavailability, 4.8 for NAD+ source and dose, 4.9 for third-party testing, 4.9 for ingredient synergy and 4.6 for taste and daily use. Four products from other brands were also included in the ranking.
According to the article, Longevity is a liposomal liquid pouch that contains 15 mg of direct NAD+, 100 mg of glutathione, 100 mg of CoQ10 as ubiquinol and 2,000 mcg of methylated vitamin B12, along with MCT oil, choline and organic avocado oil. The article lists an approximate cost of $3.63 per serving and notes that the product is independently lab tested and carries a 30-day guarantee. The article also reports that the most common customer critique concerns the product’s taste.
“We’re glad to see Longevity included alongside other products in the NAD+ category,” said a Sunny Within spokesperson. “Comparisons like this give people another reference point, and we’d encourage anyone considering a supplement to review the ingredient panels and test results and talk with their healthcare provider.”
