At MASI, we pride ourselves on offering the purest and highest quality products to support your health and longevity journey. Our supplements are manufactured to a standard not yet seen in the industry, setting a new benchmark for product quality. The MASI benchmark.
Ordering supplements online can be a daunting task. The longevity market is flooded with untraceable products produced from unknown laboratories in Asia with subpar regulatory and quality standards. When it comes to your health and longevity, we believe quality comes first.
MASI supplements are produced in a leading manufacturing facility in Germany to the strictest German standards. Equally important is that all the products are made from the top quality raw material sourced only from certified and prominent raw material providers in Germany and also France, Italy and Netherlands. This enables us to produce the highest quality and purity supplements that are free from artificial ingredients, and allergens. Our products are vegan, gluten- and lactose-free, and non-GMO, making them a safe and effective choice for supporting your longevity goals.

,
WE BELIEVE THE OPTIMAL DOSE IS CRITICAL FOR MAXIMISING YOUR WELLBEING.
This is why we provide potent yet secure dosages of the finest quality ingredients, maximizing the benefits you receive from each NMN, Resveratrol, Fisetin and Spermidine supplements daily.
A common issue with most anti-aging supplements is their poor absorption and bioavailability, which means that low oral doses might be ineffective.
MASI longevity supplements leverages cutting-edge scientific insights to inform the dosage guidelines of our products, ensuring they are both safe and potent enough to exceed the necessary absorption and bioavailability rates for tangible health benefits.
Unlike many vitality supplement competitors who offer lower-priced products with doses much smaller than those found in MASI products, our approach prevents the risk of suboptimal intracellular concentrations that offer no real advantage. Our goal stands with lifespan extension. Why compromise on your health?
At MASI, we do it differently.
- Premium NMN: 1000 mg of pure NMN
- Premium Resveratrol: 500 mg of pure Resveratrol
- Premium Spermidine: 3 mg of pure Spermidine
- Premium Fisetin: 500 mg of pure Fisetin
Recommended dosage:
- 40-50 years - 1 capsule per day
- 50 years and more - 2 capsules per day
MASI. Real dosage. Real results.
