Autophagy One - 60 x Spermidine 5mg Capsules

Every cell in your body has a cleanup process. Damaged proteins get tagged. Worn-out structures get recycled. The machinery refreshes itself. That process is called autophagy — and it slows with age.

Spermidine is one of the most studied compounds for supporting autophagy. It shows up naturally in food (wheat germ, aged cheese, certain mushrooms) but in amounts most adults can't easily reach through diet alone.

Why autophagy matters

Autophagy is the body's way of keeping its own machinery functional. When it slows, damaged proteins and worn cellular components pile up instead of being cleared. The clutter is what compounds into the visible signs of aging — slower recovery, less resilient cells, a gradual fade in baseline performance.

Researchers have studied autophagy support for decades. Spermidine is one of the few naturally occurring compounds with strong evidence behind its role in the pathway.

How Autophagy One works

Spermidine supports the cellular recycling processes that keep cells functioning well over time. It's a polyamine — a small molecule your body uses across multiple pathways, autophagy being the most studied for aging.

What's in each capsule

5mg of spermidine per serving, derived from premium wheat germ extract standardized for consistent potency. One capsule daily. No proprietary blends, no synthetic fillers.

Who it's for

Adults 40+ who want cellular cleanup support layered into their longevity routine. People already supplementing NMN and looking for the next addressable pathway. Anyone who reads the longevity literature and noticed how often spermidine comes up.

How to take it

One capsule daily, with or without food. Many people take it in the evening — spermidine is most active during the body's natural overnight repair cycle. Consistency over months matters more than precise timing.

What to expect

Cellular cleanup is invisible to the senses but compounds over time. Most people don't feel an immediate shift. The benefits show up over months as steadier baseline energy, better recovery, and the kind of cellular resilience that's easier to feel a year later than the day after.

• Activates autophagy — your cells' natural recycling system that clears damaged proteins, broken organelles, and accumulated waste to keep cells functioning at their best
• Linked to longer lifespan in a 20-year prospective study published in the American Journal of Clinical Nutrition, where higher spermidine intake was associated with significantly lower all-cause mortality
• Supports cardiovascular health by promoting the cellular cleanup processes that help maintain healthy heart tissue, blood vessels, and arterial function over time
• Enhances cognitive function — a randomised controlled trial showed improved memory performance in older adults with subjective cognitive decline after spermidine supplementation
• One of the few compounds shown to extend lifespan across multiple species including yeast, flies, worms, and mice, demonstrating remarkably consistent longevity effects
• Derived from a standardised wheat germ extract, carefully processed to deliver a reliable and verified dose of spermidine in every capsule you take
• Independently tested for purity, potency, and contaminants with every batch — because when it comes to your health, transparency and quality are non-negotiable

What is Spermidine?

Spermidine activates autophagy — your body's built-in recycling system that clears out damaged proteins and cellular debris. The importance of autophagy was recognised with the 2016 Nobel Prize in Physiology or Medicine, awarded to Yoshinori Ohsumi for his discoveries in this field.

What does the research say?

A 20-year prospective study found that people with higher dietary spermidine intake had significantly lower rates of all-cause mortality — including cardiovascular and cancer-related deaths. Kiechl et al., American Journal of Clinical Nutrition, 2018 ↗
