Think aging is written in your DNA? Research tells a different story.

A landmark study of Danish twins found that only 25% of the variation in human lifespan is genetic, with the remaining 75% determined by lifestyle choices, environment, and daily habits.1   That concept reframes aging entirely—you’re not limited by what you inherit. You shape your longevity every day.

Spermidine

Spermidine plays a critical role in several cellular functions including cell growth, autophagy, and DNA stabilization, but spermidine levels in the body decrease as we age.*

Maintaining healthy levels of this naturally occurring polyamine impact the body’s built-in renewal switch—which is essential for healthy aging.*

Customers Also Ask

1. What is spermidine?

Spermidine is a naturally occurring polyamine that plays a role in cell growth, autophagy, and DNA stabilization.* Solaray Spermidine delivers a clinically studied dose sourced from Miricell™ rice germ extract.

2. What are the benefits of spermidine?

Spermidine plays an important role in cell growth, autophagy, and DNA stabilization.* Because spermidine levels in the body decrease as we age, supplementation helps the body continue to perform these key cellular functions.*

3. What is autophagy and how does spermidine play a role in it?

Autophagy is your body’s cellular recycling system. It allows the body to disassemble damaged cell parts, which can slow or prevent function, and repurpose salvageable pieces into new, usable parts. This built-in renewal switch plays an important role in longevity because autophagy can decrease with age, leading to a buildup of damaged cells that prevent optimal function.
Spermidine plays a role in autophagy and other cellular functions including cell growth and DNA stabilization.*

4. What is a clinically studied dose of spermidine and why is it important?

A clinically studied dose is the specific amount of a substance, such as a drug or supplement, that has been established via formal scientific research.
Supplements can contain too much or too little spermidine. Solaray’s formulation delivers a clinically studied dose of 3.3 mg spermidine.

Reviews

Good looking bottle but what does it do?

"As an internal medicine doctor, I failed to find any data that confirms any reliable cardiovascular benefits of Spermadine. So, that said, I will move on to digestive tolerance. As a young male with a very active lifestyle, I was taking one capsule a day along with my daily Vitamin B complex and Vitamin D. No digestive distress was noted. Additionally, the pills are small size and easy to swallow. They come in a presentable package. Beyond that, I cannot comment much on the benefit of the product. I will not add this to my daily supplements after completing this 30 day course."

— HaiderK (3/5)

Mild energy boost and a clearer mind!

"These vitamins are great! Seems to be excellent quality, clean ingredients. They’re an easy size to swallow. They don’t have any sort of smell and the bottle they come in is a good quality typical vitamin bottle. I have felt like since I started taking them that I’ve had a little boost in overall energy and my mind feels a bit clearer than normal. I’ll be getting more and continuing to take them!"

— AlexD (5/5)

Easy to take, good quality, and so far I'm happy with the addition to my daily routine

"I've been taking Solaray UNLIMIT Spermidine for a little while now and so far I'm pretty happy with it. The capsules are easy to take and I haven't had any issues with them upsetting my stomach. It's hard to say exactly what results I'm getting from it since supplements can take some time, but I do like having it as part of my daily routine. Overall, it seems like a good quality supplement and I'd definitely consider buying it again."

— MilleB (4/5)

Helped reduce inflammation with no adverse side effects, although it had a slight unpleasant smell.

"I have been using spermidine for the last 30 days. The first thing I noticed is that the pills do have a weird smell but nothing too overwhelming. With that being said, I did start noticing a slight difference after seven days. The main thing is that it helped with my body’s inflammation by reducing it. However, I did not have any adverse side effects from it. It’s hard to say how much of the effects were from the supplements, but I will continue to use it hope that the results become even more noticeable."

— MunyrM (4/5)

Long Term Health Support

"I’ve been taking one capsule daily for about a month and although it may be too soon to feel any effects, I think I can tell a slight improvement in my daily short term memory. Spermidine is supposed to help with long term health so only time will tell. The smell when opening the bottle is very overpowering but luckily the capsule doesn’t have any aftertaste so it’s manageable."

— HaileyH (5/5)

Easy addition to my daily routine

"I’ve been taking Solaray unlimit spermidine as part of my morning routine and I like how simple it is to add to the supplements I already take the capsules are easy to swallow feel fresh and I appreciate the straightforward ingredient list and naturally occurring polyamine source. it’s still early so I can’t speak to long-term results yet but so far I’m happy with the quality and consistency."

— LuisaJ (5/5)

Working well

"I like these vitamins so far I've only been doing them for about a month but so far they seem to be going quite well. I don't necessarily feel anything different in my body but these are more for the cellular level so I know that these are working more silently! I also like that you only have to take one a day!"

— ShianeF (4/5)

Can’t really tell what it does

"When I first received this supplement I was ver excited to try it. I was going to give it 30 days and see what kind of difference it made. I even set up a journal to keep track. Umm, I can honestly say that I cannot tell you what this does. It says it was for cellular growth and has anti aging components but I can’t tell. I guess we’ll see what happens and how I feel when I go off of it. I can tell you that it was very gentle on my sensitive stomach and I did not feel any kind of side effects."

— StephanieK (3/5)

Good spermidine supplement

"I just recently learned about spermidine from influenster. It is supposed to boost autophagy, a natural process in our body to remove the broken cellular compartments and stimulate the repair process. It is advertised to support longevity, increase brain and heart health and reduce inflammation. While it sounds good on paper, I don’t know if it is true yet. At least my body tolerates it well. The pills smell a little bit like mushrooms. I think it is derived from mushrooms. It is formulated as veggie caps and tightly sealed. It is easy to take, and the dose is based on scientific studies. I would recommend regular exercise and a good daily diet as a core, and adding this supplement on top as support. I would not recommend taking this as the sole action for health."

— PhongL (4/5)

Strong smelling for sure!

"I’ve been happy with this Solaray Spermidine supplement so far. The capsules are a good size and very easy to swallow, with no unpleasant taste or aftertaste. I also like that each serving provides 3.3 mg of spermidine and the bottle contains 60 veggie capsules. One thing I noticed right away is that **the smell is quite strong when you open the bottle**. It doesn’t really bother me once I take the capsules, but it’s definitely noticeable and worth mentioning. The packaging is nice, the directions are straightforward, and it’s easy to add to my daily supplement routine. Since spermidine is something I’m taking for its potential long-term cellular and healthy-aging benefits, I don’t expect an immediate noticeable effect. Overall, I’m pleased with the quality and convenience of this supplement."
