Hair, skin, and nails are often the first places nutritional deficiencies show up. While topical products help, lasting beauty requires nourishing these tissues from within.
The Building Blocks
Biotin (B7)
Supports keratin infrastructure. Deficiency causes brittleness. Note: High-dose biotin can interfere with lab tests. Dose: 2,500-5,000mcg.
Collagen
Provides structural protein for skin elasticity and nail strength. Hydrolyzed collagen peptides are well-absorbed. Dose: 5-15g daily.
Vitamin C
Required for collagen synthesis. Also protects skin from UV damage. Get 500-1,000mg daily.
Zinc
Essential for protein synthesis and cell division. Deficiency causes hair loss and skin issues. Dose: 15-30mg.
Silica
Trace mineral found in connective tissues. Supports collagen formation. Bamboo extract is a good source.
Omega-3s
Reduce inflammation and support skin hydration. Dry, flaky skin often improves with adequate omega-3 intake.
Common Deficiencies That Affect Appearance
- Iron: Hair loss, pale skin, brittle nails
- Vitamin D: Hair loss, slow wound healing
- Protein: Weak hair and nails, poor skin elasticity
Lifestyle Factors
- Stay hydrated (skin especially needs water)
- Manage stress (cortisol accelerates aging)
- Get adequate sleep (repair happens during rest)
- Protect from sun (UV damage ages skin)
