You can't remember the last time you slept well. Your cells know why.
After 40, your body produces less of the compound that makes deep sleep possible.
Most people aren't sleeping badly because of stress or screens. It's a cellular shift, and Primeadine® was built to address it.
Sleep is when cellular repair peaks, spermidine supports that process.
Whole-food spermidine, not synthetic.
Third-party tested in Japan and the US.

MOST SLEEP SOLUTIONS MISS THE POINT
They target the symptom.
Spermidine works on the reason.
Poor sleep isn't just tiredness. It's a sign your cells aren't repairing the way they used to. During sleep, your body runs its most important renewal processes, and spermidine is the compound that drives them. The less of it you produce, the lighter and less restorative your sleep becomes.
SLEEP
Cellular repair peaks at night. Poor sleep means incomplete cellular repair. The restorative rest you used to count on becomes harder to reach.
ENERGY
Poor sleep means your cells start the next day already behind. Energy dips that follow don't fully recover.
WHY SLEEP CHANGES OVER TIME
It's not your routine.
It's your circadian clock.
Your circadian rhythm controls when you sleep, when you repair, and when you recover. Research shows spermidine plays a direct role in keeping that clock running on time. As levels decline, sleep becomes lighter, shorter and less consistent.
The key is autophagy, your cells' built-in nightly repair process. Spermidine activates it. Less spermidine means less repair, and less repair means less restorative rest.
If you track your sleep
Many Primeadine customers who use wearables notice improvements in deep sleep and HRV scores. Try taking it with your last meal of the day for best results.
THE SCIENCE
Meet spermidine.
Your cells already know it.
Spermidine is a naturally occurring compound found in every cell in your body. Its most important job is triggering autophagy, your body's built-in cellular renewal process.
What is autophagy?
Think of it as your cells' self-renewal system, clearing out damaged components and recycling them into new ones. As spermidine declines, so does your body's ability to activate it.
Nobel prize winning science.
In 2016, Japanese scientist Yoshinori Ohsumi was awarded the Nobel Prize for his discovery of autophagy, and Oxford Healthspan is the only non-Japanese member of the Consortium he leads.
INTRODUCING PRIMEADINE
Wholefood spermidine
Built around this science
Most spermidine supplements are synthetic. Primeadine® uses food-derived spermidine concentrated from whole wheat germ sourced in Japan — in the form your body was designed to recognise.
Whole-food. Food-derived.
Concentrated from whole wheat germ: not synthetic, not isolated. The form your body was designed to recognise.
Sourced and manufactured in Japan
From a JHFA-certified facility, to Japan's highest food-safety standards.
Independently tested: twice
Every batch tested in Japan and the USA for heavy metals, pesticides, mycotoxins, and potency.
Guided by Oxford science
Developed with guidance from scientists at the University of Oxford, ensuring every decision is informed by rigorous academic research.
What our customers say
WHAT TO EXPECT
Why does 90 days matter?
Primeadine® supports natural cellular processes that take time. Activity begins from day one, but cellular renewal is quiet and cumulative, building steadily with each passing month.
Most customers report more meaningful changes after 3 to 6 months. Anything shorter simply doesn't give those processes a fair chance, which is why 90 days is the honest minimum we recommend.

Description
Support healthy aging from within
Primeadine® Original is a premium, whole-food spermidine supplement made from concentrated, glyphosate-free wheat germ extract, carefully sourced in Japan.
It is designed to support the body’s natural cellular maintenance processes, which play an important role in how we age, feel, and function over time.
How it may support you
Customers often report:
• More consistent daily energy
• Improved sleep quality
• Greater mental clarity
• Healthier-looking skin and hair
These are everyday indicators of a body being supported from within.
What’s happening underneath
As we age, the body’s natural cellular processes gradually become less efficient.
Primeadine provides a food-derived source of spermidine, a compound that has been studied for its role in supporting cellular maintenance processes, including autophagy — the body’s natural “clean-up” system.
This approach is not about forcing change, but supporting the body’s own systems over time.
Ingredients
Each serving provides 1mg of whole-food spermidine from concentrated, glyphosate-free wheat germ extract, sourced in Japan.
We also defat our wheat germ to remove polyunsaturated fatty acids (PUFAs), helping to maintain stability and quality. When left in, they can go rancid and wreak havoc in your cells.
Other ingredients
• Corn-derived cluster dextrin
• Sodium citrate
Capsule
• Hypromellose (vegan capsule)
Allergens
Contains wheat (approx. 40mg gluten per serving — significantly less than a typical slice of bread).

CAPSULES
Dosage: 3 capsules daily with water, taken with your first or last meal.
First-time use:
Day 1: 1 capsule
Day 2: 2 capsules

Smoothies
Yogurt
Shakes
Breakfast bowls
Who is it for?
Primeadine® Original is designed for those who want to:
Support healthy aging proactively
Maintain energy, clarity, and vitality
Support skin and hair health from within
Take a science-informed approach to long-term wellbeing
Important information
Contains concentrated wheat germ, so it's unsuitable for those with Celiac disease, wheat allergies, or those on Autoimmune Paleo, Carnivore, or Lectin-free diets.
Consult your healthcare provider if unsure.

FAQ
Questions? We got you covered.
What is spermidine?
Spermidine is a naturally occurring compound known as a polyamine, found in every living cell. It plays a role in supporting the body’s natural cellular maintenance processes, including autophagy, which helps cells renew and function optimally.
While the body can produce spermidine, levels tend to decline with age.
What are the benefits of spermidine?
Spermidine has been studied for its role in supporting cellular health and healthy aging. Research suggests it may contribute to:
Cellular renewal processes such as autophagy
Cognitive and cardiovascular health
Hair, skin, and nail health
Energy, sleep quality, and overall wellbeing
Many of these effects are linked to its role in supporting the body’s natural maintenance pathways.
Individual experiences vary, but customers often report improvements in energy, sleep, and visible signs of vitality over time.
What's the difference between food-derived and synthetic spermidine?
The key difference lies in how spermidine is delivered and how the body may utilise it.
Food-derived spermidine
Occurs naturally within a whole-food matrix alongside related compounds, including other polyamines such as spermine and putrescine. These naturally co-occurring compounds are part of the body’s polyamine system and may support how spermidine is processed and utilised.
Synthetic spermidine
Is produced in isolation and does not come with this natural matrix. Research into long-term use in humans is still limited compared to food-derived sources.
Why this matters
In whole foods, nutrients exist within a complex structure that can influence absorption and biological activity. Food-derived spermidine reflects this natural context.
What is the best spermidine dose to take?
One serving provides 1 mg of food-derived spermidine, consistent with levels used in scientific research.
Individual needs vary. If unsure, consult your healthcare provider before adjusting your intake.
What makes Primeadine® superior to other spermidine supplements?
Primeadine® works by supporting natural cellular processes, which take time.
While activity begins at a cellular level from the outset, many customers report noticing more meaningful changes after 3 to 6 months of consistent use.
Benefits tend to build gradually with daily use.

Benefits tend to build gradually with daily use.
