I've been looking for a good supplement to support my cognitive health long-term, and this one with Fisetin and Quercetin caught my eye because of the science-backed ingredients.Honestly, it's a high-quality product. The capsules are easy to take, and I haven't had any negative side effects at all, which is always the first thing I look for. It feels like a clean, well-made supplement.I will say, after taking it for a few weeks, I'm cautiously optimistic. It might be just placebo, but it feels like there be minor brain effects. My thinking just seems a little sharper, a little less foggy. It's not a dramatic change, but it's a subtle improvement that I've noticed.My only real hesitation is the cost. It's slightly pricey for just a 1 month's supply, which makes it a bit of a commitment to keep taking it long enough to see the full benefits.Overall, I'm giving this four stars. The product is high-quality, and I think it's having a positive, albeit subtle, effect. The price is the only thing holding it back from being a perfect five. If you're looking for a well-made supplement for long-term brain health and don't mind the cost, it's definitely worth a try.
