Thirteen ingredients is a medium-length label by supplement standards, and every one of them is checkable because every dose is printed. This guide gives each nutrient its paragraph — role, dose, evidence, and whether the dose is meaningful or trace.
The honest ones are more useful than the flattering ones.
- B12 as methylcobalamin — the bioavailable form
- Zinc as zinc citrate — well-absorbed
- Choline 0.04 mg = functionally absent
- Inositol 40 mcg = far below research doses
The headline: Biotin 5,000 mcg
Covered in full on its own page. The keratin-pathway vitamin at the dose the format supports, with the FDA lab-test caveat. The headliner for a reason — and the reason the warning comes first.
The antioxidant triad: A, C, E
Vitamin A (630 mcg, 70% DV as retinyl acetate) supports cell differentiation and turnover. Vitamin C (20 mg, 22% DV) is required for collagen cross-linking — modest at 22%, and we say so. Vitamin E (7.4 mg, 49% DV as natural d-alpha tocopheryl acetate — the better-absorbed form) protects cell membranes. Together they form the antioxidant layer of the formula.
One payment, nothing recurring, sixty days to change your mind.
Order Risk-FreeThe B-complex family
- B6 (2 mg, 118% DV) — amino-acid metabolism, relevant to protein synthesis for skin and nails
- Folate (442 mcg DFE / 260 mcg folic acid, 111% DV) — cell division, critical in rapidly turning-over tissue
- B12 (6 mcg, 250% DV as methylcobalamin — the bioavailable form, a quality signal) — DNA synthesis and red blood cell formation
- Pantothenic acid (5.2 mg, 104% DV as d-calcium pantothenate) — coenzyme A pathway, sometimes called the ‘skin vitamin’ in older literature
The mineral and micronutrient layer
- Vitamin D (10 mcg, 50% DV) — skin-cell growth and repair; half the daily value is sensible given that sun exposure provides the rest for many people
- Zinc (2.7 mg, 25% DV as zinc citrate — a well-absorbed form) — wound healing, protein synthesis, immune function
- Iodine (42 mcg, 28% DV as potassium iodide) — thyroid function, which in turn influences skin, hair and nail condition
The two honest traces
Choline (0.04 mg, 0% DV) — the label prints this itself as 0%. The adequate intake is 425–550 mg. At 0.04 mg, choline is functionally absent from this formula, and we are the page that says so rather than implying presence by listing it.
Inositol (40 mcg, † no established DV) — research doses for skin and metabolic contexts are in milligrams to grams. At 40 mcg, inositol is a label entry, not a meaningful dose.
Both are on the panel because honesty means printing what is there, not what you wish were there. And stating their limitations here is what makes the rest of the label credible. Full panel: the ingredients page.
The bottom line
Biotin leads, the antioxidant triad and B-complex form the body, zinc and iodine anchor the minerals, and two entries are honestly trace. Every dose printed.
