Healthy hair, skin, and nails begin beneath the surface. While good nutrition, hydration, and sleep set the foundation, certain vitamins and minerals play direct roles in how these tissues grow, repair, and maintain strength. Deficiencies in a few specific nutrients can often show up first in dull skin, brittle nails, or thinning hair.
Research shows that targeted supplementation — particularly with biotin, zinc, folate, iodine, and B vitamins — can help maintain the structure and vitality of these tissues when diet alone isn’t enough.
Biotin (Vitamin B7)
Biotin supports keratin production, the structural protein that makes up hair, skin, and nails. Studies in The Journal of Clinical and Aesthetic Dermatology show that biotin deficiency is linked with brittle nails and thinning hair, and supplementation can improve nail thickness and hair strength over time. Common sources include eggs, almonds, and leafy greens, but supplementation may help fill nutritional gaps.
Folate (Vitamin B9) and Other B Vitamins
Folate helps form red blood cells, which deliver oxygen and nutrients to growing tissues, including the scalp and skin. Along with vitamins B6 and B12, folate also supports cell division — an essential process for new hair growth and skin renewal. Clinical research highlights that consistent intake of B-complex vitamins contributes to healthier-looking hair and improved texture, especially when combined with protein-rich diets.
Iodine
Iodine is essential for thyroid hormone production, which influences metabolism and cell regeneration. A balanced thyroid supports consistent hair growth and prevents dryness or brittleness in both skin and nails. Iodine is naturally found in seaweed, eggs, and iodized salt, but it’s also included in many hair-skin-nail supplements to maintain optimal thyroid function.
Zinc
Zinc plays a central role in protein synthesis and wound healing. It’s critical for maintaining the oil balance of the scalp and supporting the structural integrity of skin and nails. Deficiency has been linked to hair shedding and slow nail growth. Research in Dermatologic Therapy notes that zinc supplementation in individuals with low levels can help restore normal hair density and nail condition.
Vitamins A, C, D, and E (DAKE)
These fat-soluble vitamins work together to protect and maintain skin health at the cellular level:
-
Vitamin A helps regulate skin cell turnover.
-
Vitamin C is required for collagen synthesis and antioxidant protection.
-
Vitamin D supports the hair follicle cycle and immune health of the scalp.
-
Vitamin E helps maintain skin hydration and protects against oxidative stress.
Together, they help preserve elasticity, promote a healthy glow, and protect from environmental stressors like UV exposure and pollution.
Building an Effective Routine
While single nutrients can be beneficial, the most effective formulas combine multiple vitamins and minerals in balanced amounts. A daily supplement that includes biotin, zinc, folate, iodine, and B-complex vitamins — along with DAKE vitamins — supports the full structure of hair, skin, and nail growth from within.
Pairing supplementation with adequate hydration, protein intake, and antioxidant-rich foods (like berries and leafy greens) enhances results naturally. Consistency over time — not short bursts — is what allows these nutrients to work at the cellular level.
