All FAQsOur award-winning Spermidine is a natural polyamine that counteracts ageing and promotes longevity by activating autophagy, the body’s cellular renewal and recycling process.
Autophagy is an important process that occurs in cellular and tissue regeneration and it works by self-eating damaged cells and then uses some of those damaged cells to make way for cellular repair and cleaning. It is an evolutionary self-preservation mechanism that also helps remove toxic proteins in the body associated with numerous neurogenerative diseases. Sadly, as we age this process slows down. Increasing autophagy as we age is an important component in helping to slow down the ageing process and will help support better health span and lifespan. One of the main benefits of fasting is to activate autophagy which is typically triggered around 24 hours into a fast. Autophagy helps remove toxic proteins in the body associated with numerous neurogenerative diseases.
A polyamines-rich diet in Spermidine is one of the Blue Zone secrets of the Okinawans who regularly live active lives into the 90s and 100. Okinawa is regarded as one of the healthiest places to live globally, where the average life expectancy of women is 90 years old. Okinawans eat food called Natto which is naturally high in Spermidine. Okinawa, known as the land of the immortals, experience less cancer, heart disease, and dementia than Europeans. They have more centennials than anywhere else in the world and they live active lives well into their 90s.
Our new Liposomal formula represents a significant upgrade from our previous formula. The Liposomal technology uses a unique delivery method that allows for a higher number of the nutrients in a product to be absorbed by the body. Using a liposomal technology for supplements allows for better absorption, 8x times greater bioavailability, and is more biocompatible to the human body. This improvement ensures optimal efficacy and effectiveness in promoting cellular renewal and supporting healthy ageing. We use Liposomal technology for not only enhanced bioavailability, but also for protection of nutrients against the gastrointestinal tract. The liposomal delivery system allows for better penetration into cells, maximizing the benefits of Spermidine.
There is more than 20 types of polyamines present in the human body. Spermidine, spermine, and putrescine are the most prevalent polyamine present in all living organisms. The synthesis of polyamine is highest in cells of fetus and newborns due to its cell proliferative property. It was found that polyamines are loaded in breast milk.
Yes, our Spermidine is 100% gluten-free and vegan, free from soy, GMOs, and artificial fillers.
Our Liposomal Spermidine surpasses traditional Spermidine supplements in several key ways. The liposomal delivery system enhances bioavailability, ensuring up to 8 times greater absorption compared to traditional forms. This advanced formulation not only increases efficacy but also optimizes the delivery of Spermidine to cells, supporting enhanced cellular renewal, healthy ageing, and overall wellbeing.
Spermidine has been shown in studies to lengthen and strengthen hair and keep it in the growth (anagen) phase for longer by upregulating the expression of Keratin 1. Spermidine could help to support hair and nail growth by promoting cellular renewal and enhancing the body's ability to repair and regenerate cells. This process strengthens hair follicles and nail beds, leading to healthier, stronger hair and nails over time.
Taking Spermidine could help to support cellular renewal and recycling, support healthy ageing. It also promotes strong hair and nail growth. Spermidine may increase energy and fitness, and improve sleep quality.

Spermidine is a naturally occurring compound found in a variety of foods, including wheat germ, mushrooms, soy, and certain fermented products. It has gained interest in the scientific community for its potential to support the body’s natural cellular maintenance processes. One area of ongoing research involves spermidine’s connection to autophagy—a biological mechanism through which the body clears away old or damaged cellular components This natural process plays a role in maintaining cellular balance and is believed to become less efficient with age. Early-stage studies suggest that spermidine may help support this function, although further human research is needed to confirm these observations. Populations with traditionally high-polyamine diets, such as those in Okinawa, Japan, are frequently studied for their healthspan and lifestyle habits. While the relationship between dietary spermidine and longevity remains under investigation, these cultural patterns have contributed to the growing interest in spermidine as part of a proactive approach to wellness. Spermidine supplements are increasingly being used to complement balanced routines focused on healthy ageing. For best results, they should be paired with a varied diet, regular movement, sufficient rest, and a consistent self-care regimen.
Autophagy is a natural process in the body that helps maintain cellular balance by removing components that are no longer functioning efficiently. It's part of the body’s internal maintenance system and plays a role in how cells stay organised and functional over time. Often described as a type of cellular housekeeping, autophagy allows the body to recycle certain materials, breaking them down so they can be reused where needed. Researchers are exploring how this process may contribute to overall cellular health, particularly as part of the body’s natural response to ageing. While studies are ongoing, autophagy has become a topic of growing interest in discussions about nutrition, fasting, and lifestyle practices that support long-term wellbeing.
As we grow older, many of the body’s internal systems tend to become less efficient—and autophagy is no exception. Autophagy is a key cellular process that helps break down and recycle components that are no longer functioning optimally, supporting overall cellular balance and maintenance. When this process slows down, it may result in the accumulation of cellular byproducts, which researchers believe could contribute to some of the changes typically associated with ageing. These may include reduced energy levels and a general decline in cellular efficiency. Although the relationship between autophagy and ageing is still being explored, supporting healthy autophagic activity is becoming an area of interest within longevity and wellness research.
Yes, autophagy is a process that can be influenced by certain lifestyle factors. It tends to become more active under conditions where the body senses a need for internal maintenance, such as periods of low nutrient availability or physical stress. Fasting: Extended periods without food—typically in the range of 12 to 16 hours—may encourage the body to begin recycling older cellular components as it shifts its energy use. This is one of the most widely researched ways to support natural autophagy. Exercise: Physical activity places temporary stress on cells, which may help initiate internal clean-up processes, including autophagy. Regular movement is considered beneficial for overall cellular function and metabolic health. Balanced Diet: A nutrient-rich diet that includes vegetables, whole grains, and healthy fats may support cellular integrity and long-term wellbeing. Certain food compounds are also being studied for their potential to influence autophagy. While more research is needed, some emerging studies suggest that natural compounds like spermidine—found in foods such as wheat germ and soy—may also play a role in supporting the body’s autophagy pathways as part of a well-rounded lifestyle.
In addition to its role in supporting cellular maintenance, emerging research suggests that Spermidine may also play a role in promoting hair and skin vitality. One area of growing interest is Spermidine’s potential influence on the anagen phase of the hair cycle—the stage where hair actively grows. Early laboratory studies have examined how Spermidine may help support the environment needed for healthy follicle activity, particularly in relation to cellular renewal. While more clinical data is needed, these findings have led to increased interest in Spermidine as part of wellness routines aimed at supporting hair health from within. As with all supplements, results can vary, and it’s important to view Spermidine as one element within a broader self-care strategy that includes good nutrition, sleep, and stress management.
Most users report that they have seen visible improvements in their hair and nails health within 3 to 4 weeks.
Hair and nails much improved since taking
Perhaps a coincidence, but once I started taking this supplement some MS pain I'd been suffering with for months, and believed to be the new normal, cleared up.
I’m amazed by this product. I added it to my basket with my usual mnm order just to try and thought it was really only for hair/nails/skin, etc. but I feel I have so much more energy than usual since taking it and my recovery, the next day is so much better. I have a WHOOP monitor that monitors my heart rate (I’m 47) and heart rate variability etc and it has been the best it has been in five years literally since the day I started taking this and every day since. Admittedly, that has only been three weeks but I’m very impressed.
My hair is so much better. I was worried as it was thinning, but after two months I can see the new growth and family have also commented.
I believe that spermadine is a very important supplement and unless you eat a vast quantity of spermadine rich foods you should take this supplement.
