Renewal, from the cells up
Your cells are always clearing out worn parts and rebuilding. That renewal slows as spermidine levels fall with age. A daily capsule tops spermidine back up.
Activates autophagy
Spermidine triggers autophagy, the process your cells use to break down damaged components and recycle them into new, healthy ones. It’s the same renewal that fasting switches on, in a single capsule.
Healthy ageing and longevity
In a 20-year study, people who ate the most spermidine had a death risk like that of people 5.7 years younger.
20-year study of 829 adultsHeart health
In research published in Nature Medicine, higher spermidine intake was associated with lower blood pressure.
Nature Medicine, 2016Brain and memory
Older adults taking a spermidine-rich extract for three months improved their memory performance compared with placebo.
Randomised controlled trial, 2018Your first three months
Spermidine works at the cellular level, so the benefits build the longer you take it.
Build the habit
One capsule a day gives your cells steady support for autophagy, their natural renewal process.
Feel the lift
Most customers report feeling more energised and mentally clear.
Steadier every day
Energy and recovery feel more consistent, and overall wellbeing keeps building.
The long game pays off
Cellular renewal benefits accumulate with consistent, long-term use.
Typical experience based on customer feedback. Individual results vary.
Three ingredients. Nothing else.
Spermidine is a natural polyamine found in wheat germ, aged cheese and legumes. We supply it as spermidine trihydrochloride, its stable salt form, so every capsule delivers the same dose.
Supplement facts
Why longevity researchers are paying attention
From Nature Medicine to a 20-year study of everyday diets, spermidine keeps showing up in the research on healthy ageing.
20 years · 829 adults
People who ate the most spermidine had a far lower death rate
Deaths per 1,000 person-years. In this study, each standard-deviation increase in spermidine intake was associated with a 26% lower risk, after adjusting for age, sex and calories. The gap between the top and bottom thirds matched the risk difference of being 5.7 years younger.

Longer lifespan, protected hearts
Dietary spermidine extended lifespan in mice and preserved heart function through enhanced autophagy. In people, higher intake was associated with lower blood pressure.

Questions, answered
Email us and a real person will reply.
What is spermidine?
A natural polyamine found in foods such as wheat germ, aged cheese and legumes. It activates autophagy, the process your cells use to clear out and recycle worn components, and its levels fall as you age.
When will I notice results?
Most customers report feeling more energised and mentally clear within 3 to 4 weeks. The deeper cellular benefits build with consistent, long-term use.
What’s in each capsule?
10mg of spermidine trihydrochloride, plus rice flour, in a cellulose capsule. There are 90 capsules in each bottle.
How do I take it?
Take 1 capsule a day on an empty stomach, or as directed by your healthcare professional.
How long does a bottle last?
At 1 capsule a day, as the label directs, a bottle lasts 90 days. Two bottles last six months, three last nine and five last fifteen. Take more than one a day and it runs out sooner.
Can I take it with fasting, NMN or other supplements?
Yes. Spermidine and intermittent fasting both switch on autophagy, and many people combine them. It’s often taken alongside NMN or resveratrol. If you take other medicines or supplements, check with your healthcare professional first.
Is it safe to take every day?
Spermidine has been well tolerated in studies. It’s for adults only. Don’t use it if you’re pregnant or breastfeeding, and talk to your doctor first if you have a medical condition or take prescription medicine.
How fast is shipping?
We dispatch fast from within Australia. Metro delivery usually takes 3 to 5 business days and regional delivery 5 to 7. Shipping is free over $100. Below that, standard shipping is $10, and express is $13 at checkout.
