Spermidine is a naturally occurring polyamine found in foods such as wheat germ, soybeans, mushrooms, and aged cheeses. It plays an important role in cell growth, maintenance, and renewal, and has been widely studied for its relationship with autophagy, the process by which cells remove damaged components and recycle them. Autophagy is essential for maintaining cellular health and resilience, particularly as we age. As natural Spermidine intake from diet can vary significantly, supplementation has become an area of growing interest within longevity and healthy ageing research. NADdirect Spermidine is formulated to deliver a consistent, standardised dose, making it easier to support daily intake as part of a structured wellness routine. It is designed for individuals who value purity, transparency, and science-informed formulation, without unnecessary additives.
