At 30, focus on correcting deficiencies rather than taking multiple supplements blindly. A basic routine can include:
• Multivitamin (once daily)
•
Vitamin D3 (if levels are low)
• Omega-3 fatty acids
• Biotin (for hair & nails, if needed)
• Collagen (optional for skin support)
However, I recommend getting basic blood tests (
Vitamin D,
B12, iron,
thyroid) before starting supplements. A balanced diet, adequate protein, hydration, sleep, and strength training are equally important for skin, hair, and weight maintenance.
