Biotin sits at 5000 mcg and absorbs most of the discussion, because the number is so large. But thirteen nutrients are declared on the Gelagen panel, and several of the others are closer to everyday amounts. Here is the quieter half, as printed per two-gummy serving.
Vitamin C: 20 mg, 22 percent
Listed as ascorbic acid. Vitamin C is needed by the enzymes that stabilise a new collagen strand, so it is the collagen-related nutrient actually present on the panel. There is no collagen itself on the label. A fruit or a salad supplies far more vitamin C than 20 mg, so think of this as a modest top-up rather than a main source.
Vitamin D: 10 mcg, 50 percent
Listed as cholecalciferol. Vitamin D is the one that depends heavily on sunlight, diet and the season, and it supports normal function in several body systems. The figure here is half the daily value. If you already take a separate vitamin D supplement, add the two numbers together.
Vitamin E: 7.4 mg, 49 percent
Listed as d-alpha tocopheryl acetate. Vitamin E is a fat-soluble antioxidant nutrient, and it is easy to confuse with the B6 figure printed on pages for this product elsewhere. On the panel, 7.4 mg belongs to vitamin E.
Zinc: 2.7 mg, 25 percent
Listed as zinc citrate. Zinc takes part in protein building and normal cell division, which is why it appears in skin and nail formulas. At a quarter of the daily value it is a supporting amount.
Iodine: 42 mcg, 28 percent
Listed as potassium iodide. Iodine is needed to make thyroid hormones. People with a thyroid condition, or who take thyroid medicine, should ask their doctor before adding any supplement that contains iodine, and should also mention biotin, since high-dose biotin can distort thyroid blood tests.
The trace entries
Choline is listed at 0.04 mg and shows 0 percent of its daily value, and inositol at 40 mcg with no daily value established. They are on the panel for completeness. They are small and the label does not pretend otherwise.
How to use this
None of these five is a headline, and that is exactly why they matter when you are adding up your day. A multivitamin, a vitamin D tablet or a fortified cereal can each contribute the same nutrients, and the totals are what count. Write the numbers down once and you will not have to guess later.
The four largest entries, biotin, B12, folate and B6, are written up on the nutrients page. To see availability, use the order page. These statements have not been evaluated by the Food and Drug Administration, and this product is not intended to diagnose, treat, cure or prevent any disease.
