NUTRAHARMONY Biotin, Collagen & Keratin is a hair, skin, and nail support supplement for men and women, with 5,000 mcg of biotin and a full eight-vitamin B-complex in a 180-capsule bottle.
Hair, skin, and nail routines often call for more than a single nutrient. This capsule formula combines a range of vitamins and other nutrients for people looking to complement their regular beauty routine with nutritional support for the normal hair growth cycle, hair strength and structure, nail resilience, and skin hydration and elasticity. It is formulated for men and women and for all hair types, including curly, textured, and color-treated hair.
Each serving of two capsules contains a blend of vitamins B1, B2, B3, B6, and B7 (biotin), totaling 25,000 mcg; that total does not include the weight of collagen and keratin. The formula also includes collagen, keratin, hyaluronic acid, vitamins A and E, and natural botanical extracts. The listed biotin amount is 5,000 mcg.
The B-complex supplies all eight essential B vitamins, including B7 as biotin, B9 as folate, and B12 as methylcobalamin. Together, these ingredients make the product a multi-nutrient option for people seeking broader beauty-focused nutritional support rather than a biotin-only formula.
NUTRAHARMONY is formulated to support the normal hair growth cycle and help maintain hair strength and structure. It is also designed to support nail strength and resilience, as well as skin hydration and elasticity. These are nutritional support claims, not a promise of a particular result or timeline for an individual.
A 90-day study involving 80 women showed support for a healthy hair growth cycle and visible improvement in scalp skin appearance (Study #1-0602, 2024). The product has also been clinically tested in double-blind, placebo-controlled studies; study references include NCT06605768 and NCT07520019. Visible changes can take consistency: the product guidance notes that one to three courses, or 30–90 days, may be needed depending on the individual.
The supplement is made in the USA using globally sourced ingredients at GMP-certified facilities, and it is third-party lab tested for purity and quality. These details provide manufacturing and testing context for shoppers comparing beauty supplements.
The formula combines several nutrient groups in capsule form: the B vitamins, biotin, collagen, keratin, hyaluronic acid, vitamins A and E, and botanical extracts. Its multi-ingredient approach brings these components together in one product, with a focus on ingredient transparency and a formula made without GMOs, gluten, unnecessary additives, or harsh fillers.
NUTRAHARMONY Biotin, Collagen & Keratin is suited to adults seeking a capsule-based, multi-nutrient addition to a hair, skin, and nail routine, including people with different hair textures or color-treated hair. Its two-capsule serving brings biotin, a full B-complex, collagen, keratin, and other listed nutrients together for beauty-focused nutritional support.
