Description

Flexible support, designed for daily life

Primeadine® Original Powder is a premium, whole-food spermidine supplement made from concentrated, glyphosate-free wheat germ extract, sourced in Japan.

Designed for those who prefer a powder format, it integrates easily into your daily routine — from smoothies to breakfast bowls.

Each pouch provides a convenient 3-month supply.

Supporting your body’s natural processes

As part of the ageing process, cellular maintenance pathways can become less efficient.

Primeadine provides a naturally derived source of spermidine, which has been studied for its role in supporting processes such as autophagy — the body’s way of maintaining cellular health.

The goal is simple: to support the body, not override it.

How it may support you

Customers often report:
• More consistent energy
• Improved sleep quality
• Greater mental clarity
• Healthier-looking skin and hair

These are common signs of a body being supported 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

Allergens:
Contains wheat (approx. 40mg gluten per serving).

Testing results:

Certificate of analysis - toxins

Certificate of analysiss - dose

Suggested use

Dosage:
1g (approx. ½ level teaspoon) daily.

Mix into food or drink below 40°C (104°F), such as:

Smoothies
Yogurt
Shakes
Breakfast bowls

Who's it for

Designed for those who want to:

Take a proactive approach to healthy aging
Support energy, clarity, and overall wellbeing
Integrate supplementation into food-based routines
Use formulations grounded in science and quality

Benefits timeline

When to expect results

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.

I can honestly say that my energy levels are so much better than before. I sleep well, wake up feeling refreshed after a restful sleep and am ready to take on any challenges that face me. I am achieving more than people 1/2 my age.

Clementine

My deep sleep increased 30-45 mins. I had to go off for a month and noticed a corresponding decrease in deep sleep after. And obviously everything is better with quality sleep so I highly recommend this to everyone - love it.

Jeremy

My gut health has improved significantly, with general energy levels boosted and better sleep. All told I definitely feel that a good few years have been taken off.

Stephanie

I have been taking spermidine for 5 months. This is the most recent supplement I’ve added so this is the only thing I’ve changed or done differently in 5 months, and have noticed my menstrual cycle regulate, improved sleep, major hair growth! No Fall seasonal shed like I usual experience. Skin tone is better and brighter. It’s really amazing!

Faye B.

I can honestly say that this supplement has made a huge difference to my life. I am post menopausal and thought I would continue in my menopause haze forever! However, I now feel much sharper and I’m active again!

There is no question that spermidine is a crucial component to any longevity program. Thankfully, Oxford Healthspan offers an unparalleled product line. The quality is unprecedented, derived from naturally-sourced materials and manufactured in Japan. As a result, the products contain not only spermidine, but related polyamines which provide additional health benefits. As a result, I highly recommend this product line to all of my patients.

My hair was starting to go from gray back to […] dark brown. It was gray, and now it’s back to its original color. When I think about spermidine as a whole, the way I am viewing it is as a way to reduce systemic inflammation.

Primeadine is an exceptional quality spermidine that I use in many protocols, especially when I am trying to induce autophagy. These include such diverse protocols as those for tinnitus, post-viral syndromes, 'autoimmunity', and graying hair! I am especially pleased to have a gluten-free version to offer patients.

Primeadine upregulates autophagy and mitophagy, helps the immune system to rejuvenate plus it protects DNA and supports deep sleep, hair skin, and nails. It’s a staple in my supplement stack!
