Vitamin D Recommendations

All babies (especially those who are breastfed) should get 200-400 IU of vitamin D each day, from birth up to 12 months.

Why it matters:

  • Keeps baby's blood in optimal levels to support healthy bones and immune function
  • Prevents rickets (soft, weak bones) without any risk of overdosing at these amounts

How It Works

Our Vitamin D₃ Drops deliver precisely 200 IU per drop to support your baby’s growing bones, immune system, and overall health.
