Natural antiaging autophagy boosting cellular renewal Spermidine is a potent polyamine, known for inducing autophagy which is the body’s cellular regeneration and recycling process. With 60 million cells dying every minute, our bodies are constantly replenishing them. As we age this system slows down and becomes less effective, Spermidine production in our gut biome starts to deplete contributing to Spermidine levels in the cells decreasing. Therefore, it is important to consume more spermidine as you grow older. Spermidine has also shown to support overall cognition, memory, and cardiovascular health.
