About this product
Nutritional support for hair and brittle nails is more plausible than routine hair regrowth. Zinc and biotin may help when low intake contributes to problems, while the limited nail findings concern sustained biotin use over months. The 3,000 mcg biotin amount does not establish greater growth in people whose nutritional needs are already met.
The botanical additions introduce more uncertainty than the clearly stated nutrient amounts. Apple extract is identified with procyanidin-B2, but the supplied findings do not establish a clear hair benefit from its serving. Horsetail lacks a species, plant part and silicon yield, so its 200 mg weight cannot show an amount relevant to hair-strength findings.
The formula includes both 15 mg zinc and 2 mg copper, making their quantities clear. Zinc oxide and copper sulfate are less favorable mineral choices, while calcium D-pantothenate is a clearly identified B5 source. Reasonable value for biotin is tempered by costlier nutrient contributions and uncertain added value from the botanical ingredients.
Pros
Discloses all active ingredient amounts Provides biotin at an amount relevant to the limited nail findings States copper as well as zinc content Names the B5 source clearly
Cons
Zinc oxide and copper sulfate are less favorable mineral forms Horsetail has no disclosed silicon yield or botanical species Apple and millet additions do not establish extra hair-growth benefit Several nutrient contributions are relatively costly
