Vitamin D and Autism
New research is showing that up to 75% of children on the autism spectrum show significant improvement with high dose Vitamin D supplementation.
Vitamin D levels are very often significantly lower in children with autism and ADHD.
Vitamin D has many vital roles in our body, including enhancing intestinal absorption of other critical nutrients such as Calcium, Magnesium, Iron, Phosphate and Zinc. Vitamin D is also very involved with immune function and regulating the inflammatory response within the body.
Vitamin D deficiency has been proven to play a role in many conditions such as autoimmune and behavioral disorders.
Unfortunately, very few foods contain Vitamin D. It is pretty limited to Wild Caught fish (salmon), mushrooms and some shellfish as well as fortified milk. Most of our Vitamin D supply is meant to come from the sun.
Recommended intakes for infants and children vary from 400IU to 1000IU per day depending on specific needs of the child.
However, higher doses are many times warranted for certain conditions and when deficiency is known.
Serum (blood) Vitamin D levels are very important to know prior to supplementing and should be checked again after about 6 months of supplementing. Ask your doctor or healthcare provider for the 25(OH)D, also called 25-hydroxyvitamin D. According to research, ideally levels should be at least 45ng/ml.
Reports and research shows that there appears to be better cognition, focus, and eye contact in autism spectrum disorders and ADHD as vitamin D levels are normalized.
