Spermidine
A natural polyamine that induces autophagy, the body's cellular cleanup process.
Also known as: Wheat germ extract
Overview
Spermidine is a polyamine compound found in all living organisms that plays a vital role in cell growth, proliferation, and differentiation. Its primary anti-aging mechanism is the induction of autophagy, a process where cells degrade and recycle their own damaged components. Autophagy declines with age, and by stimulating it, spermidine helps maintain cellular health and function, which is linked to improved healthspan and longevity.
Key Benefits
Autophagy Induction
Spermidine is a potent inducer of autophagy, helping cells to clear out waste products and damaged organelles, which is essential for cellular rejuvenation.
Cardioprotective Effects
Studies have linked higher spermidine intake with lower blood pressure and reduced risk of cardiovascular disease.
Neuroprotection and Memory
By promoting autophagy in brain cells, spermidine may help protect against neurodegeneration and support cognitive function.
Dosage & How to Take
1-5 mg of spermidine per day.
| Purpose | Dose | Notes |
|---|---|---|
| General Health and Autophagy Support | 1-2 mg/day | A common dose found in many supplements, often derived from wheat germ. |
| More Targeted Longevity Support | Up to 5-10 mg/day | Higher doses are used in some studies, but most supplements are in the lower range. |
Best Time to Take
No specific timing is required. Can be taken with or without food.
With or Without Food
Can be taken with or without food.
Forms & Bioavailability
| Form | Absorption | Best For | Notes |
|---|---|---|---|
| Spermidine-rich Wheat Germ Extract | Good. This is the most common and well-researched source. | General supplementation. | Supplements are typically standardized for their spermidine content. |
| Synthetic Spermidine | High. | Research and high-purity applications. | Less common in consumer supplements but offers a pure form of the compound. |
Side Effects & Safety
Common
- Extremely well-tolerated. No common side effects are known as it is a natural part of the diet.
Rare
- None known.
Contraindications
- Individuals with a wheat allergy or severe gluten intolerance should choose a spermidine source other than wheat germ extract.
