During the 1930s, many adults and infants were suffering from vitamin D deficiency and to combat this problem, the American government implemented the milk fortification program. Now vitamin D has been added to dry cereals, orange juice, yogurt, and margarine. In the United States infant formula is also regulated and must contain 40-100 IU/100 kcal of vitamin D and 40-80 IU/100 kcal in Canada (NIH).
Vitamin D Chart
The United States Food and Drug Administration works diligently monitoring the nutrient contents, in products. The daily value for vitamin D is 400 IU, but labels do not have to expose this information, unless they guarantee that they are fortified with this very important nutrient.
While UVB radiation are the best source of vitamin D most individuals are more concerned about skin cancer, so they will don their sunscreen, which decreases sun exposure and affects vitamin D synthesis. Since this nutrient is stored in the adipose tissue and liver, many individuals that have been diagnosed with vitamin D deficiencies will gain more body weight that those with normal levels.
Recommended Vitamin D Dosage
The recommended vitamin D dose of sunshine exposure should be approximately 5-30 minutes, but only between the hours of 10:00 a.m. and 3:00 p.m. and at least bi-weekly. Fortified foods and supplements, along with sun exposure can help combat this condition.
- Breastfed (0-12 months) infants – 400 IU/daily
- Toddlers and adolescents between the ages of 1-13 should consume 600 IU/daily
- Adolescents and older adults between the ages of 14-70 should consume 600 IU/daily
- Pregnant and lactating females between 14-50 years old should consume 600 IU/daily
- Over 70 years of age 800 IU/daily is recommended
While food and sun is the biggest source of vitamin D, some individuals will be required to take a daily supplement to suffice their needs.
Vitamin D for infants will most be obtained from formula or breast milk. These vitamin D dosages are necessary to combat weak bones, poor immunity, and infection.
Vitamin D Drops For Infants
When purchasing vitamin D drops for babies and infants, you need to make sure that they are regulated by the FDA, because they ensure that these consumable products are safe for human consumption.
Always make sure that you consult with your pediatrician, before administering any type of supplement for any child under the age of 6. Infants and children with a serum 25-hydroxyvitamin D concentration of below 30 nmol/L or 12 ng/mL, they will be at a high risk for rickets. Adults with these levels will be at a high risk for osteomalicia (weak bones).
Vitamin D toxicity can lead to rental stones, weight loss, nausea, and constipation. It is very important to monitor your child’s intake of vitamin D with the help of your pediatrician to prevent this from occurring.
