ResveratrolRich®, Resveratrol Concentrate, Super Strength, 60 Vegetarian Capsules

Excellent! I've been using it for a month, and the results are good. Hydration Boost: My skin feels softer and more hydrated throughout the day, even in dry weather. I have sensitive skin, and this product didn't cause any irritation or redness. Pleasant Scent: no scent, small pills

I've been taking resveratrol for a while, amongst other supplements to stay young. I'm not sure if they help, and I'd look much worse if I didn't take them, so I keep on taking them just in case 😅 I'm 53 and people say I look young for my age...

One of my choice in my list. I re-buy it many times, share with you guys and it's good! I am sure.

I love this product, I have been using this product for about 6 months and have felt an overall improvement in my health. Any product one takes, it does take a few months before it starts to work. We didn't get to where we're at overnight so it does take time for improvement.

The supplement has a strong antioxidant and anti-inflammatory effect, supporting the work of the heart and brain. It improves memory and concentration, blood circulation, normalizes cholesterol and has antiage effect in general. The product is made in the more useful form trans-resveratrol.

This resveratrol supplement impressed me with its quality and carefully selected ingredients. The size of the capsules is convenient to take daily, and the package is compact and well-sealed. I started using it mainly for its antiage properties, and I’ve already noticed a reduction in fine wrinkles and an improvement in my skin texture. Another big benefit is its help with inflammation—something I didn’t expect but really appreciate. The taste is mild and not unpleasant, especially compared to other supplements. A great choice if you’re looking to boost your skin and overall health with resveratrol.

Well you know what I mean. Ostensibly it has the stuff inside of it that it says it has. I need the benefit of quality resveratrol for various purposes, so as long as that ingredient truly is in this package then we're all good. There is no taste as it is inside capsules.

I take one capsule daily. Not sure if working or not, but I have not been sick in a very long time and feel good. I bought this brand after doing a lot of lable reading. I wanted to get the best product for the price I could find. Most other brands you have to take more capsules then I wish to take in a day. This was the best concentrate I found for the price I was willing to pay. I bought online because it's more expensive in my local stores. However, it is about the same price at Mother's Market, but it's a drive to get there. With the price of gas, it would end up costing more. Ordering online is so fast and easy and saves wear and tear on my car. Yes, I would recommend this product to those people that would like extra antioxidants added to their health!

Supplement name: Natural Factors, Resveratro Rich®, Resveratrol Concentrate, Super Strength, 60 Vegetarian Capsules Supplement scores: 6 Introduction & context: This supplement delivers 500 mg of trans-resveratrol per capsule, sourced from Japanese knotweed (Polygonum cuspidatum). Claimed benefits include cardiovascular support, antioxidant protection, and healthy aging. Priced at around $0.67 per capsule, it carries NSF certification for sport and quality. No batch-specific lab data on contaminants is publicly available. Evidence summary: Human trials on resveratrol are numerous but inconsistent. A 2023 meta-analysis (10 RCTs, n=664) found modest reductions in systolic blood pressure (-2.6 mmHg) and LDL cholesterol (-1.9 mg/dL) at doses ≥300 mg/day, but no significant effects on fasting glucose or body weight. Notably, no trials in this analysis used 500 mg/day. Bioavailability remains a challenge; standard resveratrol has poor absorption (AUC0-t ≤100 ng·h/mL), though some formulations (e.g., phytosomes) improve it modestly. Formulation & quality analysis: The product uses trans-resveratrol, the active and bioavailable isomer. However, it lacks bioavailability enhancers like piperine or lecithin. Vegetarian capsules and cellulose filler are standard and unremarkable. The absence of third-party contaminant testing raises minor concerns about purity. Safety & interactions: Resveratrol is generally well-tolerated up to 5 g/day in short-term studies. Potential risks include bleeding disorders and interactions with anticoagulants or CYP450 substrates. Caution is advised for pregnant/lactating women and those with hormone-sensitive conditions. Value & practicality: At $0.67 per 500 mg dose, it’s priced competitively with similar products. However, the evidence for efficacy at this dose is weak, and better-absorbed formulations may offer superior value. Alternatives like pterostilbene (a methylated resveratrol analog) show promising bioavailability data (AUC ≤4× higher). Overall verdict + score: Weak evidence, standard formulation, and uncertain purity earn this supplement a score of 6. While not harmful, it’s unlikely to deliver meaningful benefits at the studied dose. Who it's for: Individuals curious about resveratrol’s potential may try it, but temper expectations. Those seeking cardiovascular or longevity support might consider higher-dose, bioenhanced options or prioritize proven alternatives like omega-3 fatty acids or CoQ10. I would not take or recommend it based on current evidence.

fantastic quality ingredients are great I love this company size is good enough and benefits are felt in no time.
