This fisetin supplement provides powerful flavonoid support beyond what is typically available through food alone.*
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.

Fisetin is a powerful flavonoid, and flavonoids are important for long-term health.* Kiwis and strawberries contain a small amount of fisetin, but most people do not consume enough through diet alone.
One serving of Solaray Fisetin sourced from smoketree branch contains 10x more fisetin than an average cup of strawberries.

"Solaray Fisetin supplements are lab verified, gluten free, and vegan. Fisetin is a plant flavonoid from the polyphenol family. Fisetin acts as a powerful antioxidant. Solray’s Fisetin contains ten times more Fisetin than a cup of strawberries. Just take one VegCap daily with a meal or a glass of water. I received this complimentary in exchange for an honest review."

"I have been using Fisetin a little over one month now. I have noticed positive changes in how I feel day to day. Prior to taking Fisetin I was experiencing feelings of brain fog and tiredness even upon waking after sleeping all night. After taking Fisetin I just feel better, the brain fog is gone, as well as that lack of energy I had. I recommend this product to those experiencing lack of energy and brain fog."

"Solaray Fisetin is a simple way to get my daily flavonoid support. I take this every evening before bed, and I love how just one capsule has 10x more Fisetin than a cup of strawberries. Now that I’m over 40, this is especially important to add to my routine for my long-term health. Loving the boost of antioxidants and easy addition to my vitamin regime!"

"The delivery is fast enough. The product does not have any side odors. Medium-sized capsules. The capsules are vegetarian. It contains an Antioxidant. there are 30 capsules in a jar, I drank them as a dietary supplement. I can't say anything bad. I didn't find any miraculous properties either. I received the product for free from Influencer in exchange for an honest review."

"The Solaray UNLIMIT is a great source of Fisetin and flavonoid support! Please use as directed. Each VegCap contains 250 mg of Fisetin. This dietary supplement contains 10 times more Fisetin than a cup of strawberries, so it’s a very effective source. There are 30 servings per container and the source is Fisetin from Smoketree, essentially branch extract."
— AudrinaN (5/5)
"This supplement seems to absorb pretty well and while it’s difficult to see any significant difference day to day, does seem to help with general inflammation. I don’t usually have an issue swallowing pills but these are pretty hard to get down. There are also misspellings on the label which doesn’t really improve my confidence. An okay supplement for an okay result."
— KaylaH (3/5)
"I didn't really notice this supplement do anything in the first month of taking it. It was a larger capsule but I had no trouble swallowing it with my other supplements. It didn't really have a taste"
— PattyS (3/5)
"Fisetin is something I had never quite heard of before, but was interested in trying out. These capsules are pretty large, so they may be difficult to swallow for some. There’s no weird smell or aftertaste, so that’s a plus. Overall however, I do not notice any changes to my health. Not sure what they’ve done if anything. They seem pretty costly for the quantity, so personally I wouldn’t repurchase."
— HayleyH (3/5)
"A great formulation and the quality seems promising. I did a little research and found that if you take it with a meal that has healthy fats, it absorbs better. No noticeable negative side effects so far. Once I’m done with this first bottle I plan to repurchase. 30 day supply, I’m about a week in and have high hopes!"
— KatieD (5/5)
"This supplement is great targeting zombie cells and reducing inflammation and oxidative stress. Biggest thing you will notice is puffiness and inflammation go down with consistent use throughout the body. 250 is a good size. The pills are not too large or hard to swallow. Great price."
