Sunny Within, a company that makes liposomal dietary supplements, was named in The Where Business’s ranking of the best longevity supplements, which compared five products on criteria related to ingredient form, formula breadth and testing transparency.
The Where Business is a retail-focused blog that publishes comparison guides and rankings across consumer product categories, including beauty, supplements, fitness, electronics and home goods. Its longevity supplement guide compared five actively sold products using each manufacturer’s published supplement facts, stated mechanism, direct pricing and testing documentation.
According to the guide, products were scored on six weighted criteria: ingredient form and bioavailability at 25 percent, formula breadth at 20 percent, testing and transparency at 20 percent, clinical evidence at 15 percent, cost per month at 10 percent and daily usability at 10 percent. The guide states that no dietary supplement has been shown to extend human lifespan.
The Where Business ranked Sunny Within’s Longevity formula No. 1 among the five products evaluated, citing its ingredient forms, formula breadth and fully disclosed ingredient amounts, according to the ranking.
Longevity is a once-daily liquid supplement sold in single-serve pouches. Each serving contains 15 mg of NAD+, 100 mg of glutathione, 100 mg of CoQ10 as ubiquinol and 2,000 mcg of vitamin B12 as methylcobalamin, alongside vegan lactoferrin, MCT oil, choline and organic avocado oil. The formula is vegan, sugar free and gluten free, and contains almonds. The company states that each product is independently tested for purity, potency and safety, with certificates of analysis posted on its website. A 30-count box is priced at $109 and comes in Strawberry Lime and Watermelon Lime flavors, backed by a 30-day satisfaction guarantee.
“We designed Longevity to fit into a simple daily routine, and we appreciate that the guide looked closely at the formula and ingredient amounts,” said a Sunny Within spokesperson.
