Boosts autophagy, which declines with age, and promotes cellular renewal

Can I just take some chlorella instead of buying this?

There are many different strains and sub-strains of Chlorella, each with their own unique nutritional profile. For instance, some strains of chlorella are high in iodine. Ours is not. Working together with our Japanese partner, we tested these strains of Chlorella looking for significant concentrations of polyamines.

Primeadine GF uses a sub-strain of Chlorella that is uniquely high in spermidine. This needs to be tested for every single batch, because the amount of spermidine varies from batch to batch based on exposure to the sun and other weather conditions.

What are the benefits of taking both?

For those who want to take their autophagy to the next level, we suggest taking Primeadine GF in the morning and original Primeadine in the evening or before bed to help your gut biome produce its own spermidine at night.

How is this different from Primeadine® Original?

Primeadine Original and Primeadine GF are both wholly food-derived with the amount of spermidine, 1mg, that has been used in human clinical trials showing enhancement of memory and cognition. 

Primeadine Original is derived from concentrated, defatted wheat germ and has a small amount (40mg) of gluten. We have been unable to recommend this to clients who are celiac or suffer from Small Intestinal Bacterial Overgrowth (SIBO) or Leaky Gut as a result. 

Because we know that spermidine can be helpful to sealing the gut lining, we wanted to find a source of spermidine that would be suitable for these individuals. 

Primeadine GF contains chlorella which is itself a good source of naturally occurring nutrients, including B vitamins such as folate and B12, as well as iron. These are all important nutrients for women of childbearing age. In addition, for those individuals who are unable to metabolize folic acid, this is a source of bioavailable folate. 

Primeadine GF is a source of vitamins D and K, both of which are needed to drive calcium to the bones. 

In addition, Primeadine GF contains nobiliten, a molecule shown to trigger autophagy and pairs nicely with spermidine. Because spermidine has natural anti-inflammatory properties, we wanted to enhance this even further by adding in some turmeric. 

As a source of polyamines, Primeadine GF contains both spermidine and putrescine, a precursor to spermidine to help your body recycle and manufacture more of its own spermidine.

All our ingredients are sourced and manufactured on the Longevity Blue Zone of Okinawa in Japan in FDA registered facilities and to ISO22000 standards, the highest food grade manufacturing standards that exist. 

Which one should I take?

If you are celiac, have Leaky Gut or SIBO, are on an Autoimmune Paleo or Lectin-free diet, or are gluten sensitive, then Primeadine GF is a good choice for you.

    You MUST try Primeadine! Results will blow your mind!

    I am 57 and healthy, or so I thought before starting to take Primeadine GF. I’ve always lived a healthy an active lifestyle, but when menopause hit me at 50, my whole self changed, starting with the thin hair, dry skin and very low energy level.

    I am in my 2nd month of taking Primeadine GF and the positive changes I’ve experienced are astonishing! My energy level has gone up the roof, to the point of me getting embarrassed in my spin class when my gym mates can’t keep up with me. I feel bad for them and now want to spread the love and recommend Primeadine GF, so that they too can feel as wonderful as I do.

    My skin is glowing, my hair is thicker and I have no shortage of healthy baby hair growing. I can now jog 7 miles straight, whereas before I could only do a combination of power walk + jog 3.7 miles. Even my sex life has improved because of my beautiful energy.

    Thank you Leslie Kenny and Oxford Healthspan for changing my life for the better!!!

    Improved aerobic endurance and exercise recovery

    I'm a 53 year old runner and have been taking Primeadine GF for several months. I recently increased my intake to 6 tablets per day. My recent blood test results showed increased hemoglobin and RBC counts. More importantly, I've notice that my aerobic endurance has improved significantly and my recovery is better. Primeadine GF is a game changer for athletes!

    Noticing multiple beneficial effects already.

    I have been taking the daily dose of Primeadine GF for 4 months now and have definitely noticed more than one difference already: my skin has improved (and been complimented on by others), my nighttime hot flushes have stopped so my sleep quality has improved and overall energy levels have increased. Having read the science behind this supplement I am committed to taking this on a long term basis. Would certainly recommend it.

    Deep sleep impact.

    I’ve been struggling with deep sleep for quite some time now, almost a year. My avg was 30mins a night, and being a functional health consultant I tried every tool I had on my belt to sort it but sadly nothing worked. This meant my sleep debt was high, my body was massively under recovered and my gym sessions dropped from 5 days a week to 2 max, I just wasn’t recovering enough. I had the fortune of meeting Leslie and hearing the amazing results others had with primeadine so thought why not try one more thing.

    I’m so glad I did, my deep sleep has increased by 1hr after only 2 weeks. And this one extra hour has been consistent every single night. Some nights it’s higher but never lower. I’m so impressed with this supplement I’m recommending it to all my clients whether they have deep sleep issues or not as sleep is the key to all things health and therefore should be everyone’s first focus on their health journey.

    Thank you Leslie and team for such a fantastic product.
