Vitamin A
630 mcg · 70% DVSupplied as retinyl acetate, the preformed animal-form of the vitamin rather than beta carotene. Vitamin A is bound into the way skin cells mature and turn over, which is why retinoids — its prescription relatives — sit at the centre of dermatology. This is a nutritional amount, not a retinoid dose. Preformed vitamin A accumulates, and that is the reason the label warns pregnant women to ask a doctor first and the reason you should not run a second vitamin A supplement alongside it.
Vitamin C
20 mg · 22% DVAscorbic acid, and the most defensible skin entry on the whole panel. Your body cannot assemble its own collagen without vitamin C acting as a cofactor for the enzymes that stabilise the collagen triple helix. That is a real, textbook biochemical role. It is also the reason the collagen-in-a-gummy confusion around this product is so unnecessary: the formula supports the collagen you make rather than supplying any.
Vitamin D
10 mcg · 50% DVCholecalciferol, which is the D3 form, at 400 IU in the old units. Vitamin D receptors sit in the hair follicle and the keratinocyte, and shortage is genuinely common in anyone who works indoors or lives at latitude through winter. Half the daily value is a supporting amount, not a correction of a deficiency — that needs a blood test and a doctor.
Vitamin E
7.4 mg · 49% DVD-alpha tocopheryl acetate, the natural-source form. Vitamin E is fat-soluble and sits in cell membranes acting as an antioxidant, which is where the skin interest comes from. Note this number: 7.4 mg is vitamin E. Several pages about this product misattribute it to vitamin B6, which is on the panel at 2 mg.
Vitamin B6
2 mg · 118% DVPyridoxine hydrochloride. B6 is a workhorse in amino acid metabolism, and keratin is an amino acid product, so the connection to hair and nails runs through protein handling. Very high long-term B6 intakes are associated with nerve symptoms; 2 mg is nowhere near that territory, but it is worth knowing if you take a separate B-complex as well.
Folate
442 mcg DFE · 111% DVPrinted as 260 mcg of folic acid, expressed as 442 mcg of dietary folate equivalents. Folate is required for DNA synthesis and therefore for cell division, and a follicle in its growing phase divides relentlessly. If you take methotrexate or an anticonvulsant, folate interacts with both and this is a conversation for your doctor rather than a footnote.
Vitamin B12
6 mcg · 250% DVMethylcobalamin, which needs no conversion step in the body. B12 supports red blood cell formation, and red blood cells are what deliver oxygen to the base of every follicle. It is the first nutrient to run short on a plant-based diet, and shortage tends to announce itself as fatigue long before anything visible happens to hair.
Biotin
5000 mcg · 16,667% DVThe reason most people buy a gummy like this and the entry that needs the most care. Biotin is a coenzyme in carboxylation reactions and it is genuinely involved in keratin production. True biotin deficiency is rare and does cause hair and nail problems; correcting a deficiency you do not have is a different proposition. At 167 times the daily value this dose interferes with several laboratory immunoassays, which is a real, documented, clinically significant problem and the single most important fact on this page.
Pantothenic acid
5.2 mg · 104% DVVitamin B5 as d-calcium pantothenate. It is the backbone of coenzyme A, which every energy-yielding pathway in the body routes through. Nothing about it is exciting and everything about it is necessary. Just over the daily value.
Choline
0.04 mg · 0% DVCholine bitartrate at forty micrograms, which the panel itself rounds to zero percent of the daily value. We are not going to pretend this is doing anything. It is on the label, so it is on this page, and honest reading of a panel includes the lines that do not help the sale.
Iodine
42 mcg · 28% DVPotassium iodide. Iodine is a thyroid nutrient, and thyroid function has an obvious and well-documented effect on hair. That also makes it the entry to raise with your doctor if you have a thyroid condition or take levothyroxine, especially alongside the biotin note about thyroid blood tests.
Zinc
2.7 mg · 25% DVZinc citrate. Zinc is involved in wound healing, immune function and skin repair, and zinc deficiency produces recognisable skin and hair changes. A quarter of the daily value is a modest, sensible top-up rather than a therapeutic dose, and it is well below the level at which zinc starts competing with copper absorption.
Inositol
40 mcg · † DVCarries a dagger on the panel, meaning no daily value has been established. Inositol is a sugar alcohol involved in cell signalling and it appears in a lot of beauty formulas. Forty micrograms is a very small amount. Read it as a formulation inclusion, not as an active.
