Toniiq Ultra Concentrated 500mg Spermidine Supplements are designed for both men and women. This product features non-synthetic spermidine standardized to no less than 1% spermidine, providing 5mg spermidine per serving from rice germ extract. Spermidine is a type of polyamine that plays essential roles in cellular functions, supporting cellular health, autophagy, and potentially enhancing longevity. The rice germ-sourced spermidine is at least 9-11x more concentrated than wheat germ-sourced spermidine, gluten-free, and offers better value per serving. Toniiq products are produced in a GMP-certified facility in the USA, with each batch tested for purity and active ingredients.
