Micronutrients & recovery
Vitamin D deficiency is a widespread pandemic in industrialized countries, linked to osteoporosis, fractures, and increased risk of chronic diseases, requiring supplementation of 400 IU/day for infants, children, and adolescents.
If you are a parent, ensure your children get 400 IU of Vitamin D daily, especially if they spend little time outdoors. This prevents rickets and supports bone health.

Vitamin D deficiency, once pandemic among children in the industrialized countries, is now found to be extremely widespread, can lead to osteoporosis and bone fractures... The American Academy of Pediatrics (AAP)... recommended an increase of the levels of vitamin D supplements to 400 International Units per day.
Why this rating
Based on AAP guidelines and observed clinical rickets emergence.
