grape seed extract supplementation systematic review
| Ingredient | Label amount | Practical assessment |
|---|---|---|
| Lycopene 10% | 5,000 mcg | If “10%” denotes standardization, this may provide only about 0.5 mg lycopene, a very small dose. Evidence for broad health benefits from lycopene supplements is limited. |
| Lutein 8% | 2,000 mcg | Potentially only 0.16 mg lutein. This is far below the 10 mg lutein used in the evidence-based AREDS2 eye formulation. |
| Beta-carotene 10% | 5.17 mg | Potentially about 0.52 mg active beta-carotene if the 10% describes active content. It is not a proven general antioxidant therapy. |
| Grape-seed extract 10% | 10 mg | Likely only about 1 mg active extract, depending on what the “10%” means. Trials suggesting changes in oxidative-stress biomarkers typically use much higher doses. |
| Zinc sulfate monohydrate | 27.45 mg compound | This likely corresponds to about 10 mg elemental zinc, based on the stated 58.33% RDA. Useful for preventing or correcting zinc deficiency, not a general antioxidant treatment. |
| Selenium | 70 mcg elemental selenium | Around a normal nutritional dose. Selenium is required for antioxidant enzymes, but extra supplementation has not shown general preventive benefit in selenium-replete people. |
