Best Flavonoid Supplements of 2026

"I've tried a few different hangover products, but this one stands out as the most effective and noticeable remedy. Not only do I feel significantly better the next day, but it's also more affordable than what I used before. The fact that it includes liver support ingredients makes it my go-to choice now."

"After using this during a week of daily vacation drinking, I was amazed — no hangover, not even a headache! My husband and I don't normally drink much, but these pills made a huge difference. They truly work like magic and I will definitely buy them again."

"I've relied on these for weddings, reunions, and big nights out. They allow me to be fully functional the day after drinking. I did notice that if I don't drink enough water with the pills, I can get a racing heart and restlessness at night, but drinking plenty of water with the supplement fixes this. Overall, it's been a miracle supplement for my hangovers."

"My doctor recommended this blend and I've found it to be a fantastic immune defender whenever I feel unwell. It's very effective for me, easy to take, and I think it's a great value."

"Whenever I feel a cold coming on, I increase my dose and it really helps shorten the duration of my symptoms. I've been satisfied enough to repurchase whenever I need more."

"I love that this supplement combines several vitamins and herbs into one pill, which makes my routine much easier. It's easy to swallow, and while I just started taking it, I prefer this over taking multiple pills."

"After my husband started taking this for his tinnitus, he experienced a clear reduction in ear ringing. When he stopped before a medical procedure, his symptoms got worse again, so we're convinced it's effective. I'm usually skeptical about supplements, but this one really made a difference in our home."

"I've struggled with tinnitus for over two years and tried many supplements, but none have helped so far. I gave Lipo-flavonoid a shot because of the money-back guarantee. Unfortunately, after nine days, my symptoms seemed worse, and I felt a bit unsteady, so I decided to stop. It's worth a try, but for me, it didn't work out."

"With age, my tinnitus has gotten worse and become more noticeable, especially in the mornings. After starting this product, my mornings are quieter and I've seen real improvement. I'm also using it with another supplement for added benefit, and together, they've significantly reduced the ringing in my head."

"I've dealt with tinnitus for nearly 20 years due to my career in EMS and exposure to loud noises. To my surprise, this supplement has quieted my tinnitus almost completely. It's not a cure, but it provides noticeable relief as long as I remember to take it daily. Missing a dose brings the noise back, so consistency is key. For me, this has been a game-changer in restoring peace of mind."

"After taking the recommended dosage for several weeks, I noticed my tinnitus level dropped significantly—from a 6 out of 10 to just a 1. I did have to stay patient, as it took nearly a month to kick in. Busy, stressful environments still make it flare up, but overall, my daily life has improved. I also take vitamin B12 alongside this product."

"I followed the instructions and used this supplement as directed, but unfortunately, I noticed no change in my tinnitus after 17 days. Additionally, I was disappointed to find it contains ingredients like titanium dioxide and Red Dye #40, which I try to avoid. While it may help others, it didn't work for me."

"As someone with an autoimmune condition and a weak immune system, I’ve noticed that since using this product, I haven’t been sick or had a cold for years. It’s definitely helped me stay healthy."

"Being a high school nurse, I’m exposed to a lot, but taking two daily has really helped keep me from getting sick."

"My healthcare provider recommended this, and since starting it, I’ve managed to stay healthy—I truly appreciate how well it works!"

"After struggling with BPPV vertigo for a long time and trying various therapies, I finally found relief using this along with the red bottle version. It really helps if you're patient; for me, it took a few weeks to kick in. I’ve regained control over my dizziness and can do Pilates again."

"I started taking this daily after my friend recommended it for my vertigo, and it’s made a world of difference. The spinning sensations vanished, and even when I stopped for a week, I didn’t notice any negative effects. This little pill truly worked for me."

"This supplement didn’t quite work for my ears. My ears stayed clogged and itchy despite finishing almost the whole bottle. While I like the Lipo Flavonoid for tinnitus, this particular product didn’t help my symptoms."

"I've really enjoyed this product—the taste is perfect when I mix it with hot water, honey, and a scoop of collagen. It's become my favorite healthy pick-me-up during colder months."

"After trying a scoop in Greek yogurt and then in my morning coffee, I noticed a great improvement in my mood and energy. The chocolate flavor is deep but not too bitter, and it blends well if the liquid isn't too hot."

"Honestly, I was let down by this cocoa. The name made it sound decadent, but in reality, the texture was gritty and the taste extremely bitter. It didn't dissolve well and left an unpleasant aftertaste. I wouldn't recommend it."

"I've really come to appreciate this brand for its clean, minimal ingredients and high quality. The capsules are easy to take, gentle on my stomach, and I notice a boost in my immune system. Plus, the value for money is great!"

"Pure Encapsulations Quercetin has been helpful for my histamine and mast cell issues, providing noticeable support for flare-ups and sensitivities. I also like that it's filler-free and easy to tolerate."

"After switching from my old quercetin brand, I found that this one works well, especially alongside my medication for uric acid. I did notice some extra joint pain at first, but adjusting my dose helped. I feel it's effective overall."

"I've made this a monthly staple in my home because the product provides excellent immune support and anti-inflammatory effects. The fact that it works as a zinc ionophore is its real benefit, helping zinc get where it needs to go for overall health. I highly recommend taking both this and zinc together."

"I've noticed that this supplement gives me a significant energy boost—it takes a few hours to kick in but then lasts all day. At first, I didn't appreciate that effect, but now I find it really useful. As for immune benefits, I can't say, but for sustained energy, it's impressive."

"I started using this after hearing quercetin helps with allergies. It has greatly reduced my urticaria, helped me avoid urinary infections, and even made flu symptoms milder. After six months, my autoimmune inflammation is now normal—all without needing immunosuppressants. It's also non-drowsy and less expensive than allergy meds."

"As a mom with a hectic schedule, I truly appreciate how Cata-Kor NMN keeps my energy levels steady without any crashes. It fits seamlessly into my morning routine and is gentle on my stomach, which is a must for me. After a few weeks, I feel more refreshed, balanced, and able to manage my busy days. This supplement has become an essential part of my wellness routine."

"I've tried several energy supplements, but this NMN formula stands out. The combination of NMN, Quercetin, TMG, and Resveratrol is impressive and I noticed improved energy and focus quickly. The capsules are easy to swallow and feel high quality. I highly recommend it for anyone looking to support their daily vitality."

"After hearing about NAD from my sister, I decided to try this product. I found the capsules easy to take with no taste and have already noticed an increase in my energy levels and improved skin appearance. I'm confident that continued use will bring even more benefits."
