According to studies, exposure of sunlight which is best for vitamin D production is between 10am to 3pm. Experts have warned us about the exposure of UV radiation from the sun can cause skin cancer. Sometimes, it is not always possible for our children to get enough sunlight exposure (maybe due to weather, geographic reason and culture) to produce enough vitamin D. Therefore, parents shall look for alternative source of vitamin D for their health benefits.

Vitamin D is usually deficient for exclusive breastfed babies, because breast milk contain lower vitamin D compared to formula powders which are fortified with vitamin. It happens if mother is less expose to sunlight or without taking any health supplement.

Therefore, obviously for lactating mothers need to take enough vitamin D to provide sufficient vitamin D for the nursing babies. Consult your doctor about the safety dosage before taking the supplement.

According to the experts, consumption of food with vitamin D will only provide 100 – 200IU of vitamin D daily but exposure to sunlight with 30% of body part expose for 15-30 minutes from 10am to 3pm will provide 10000 – 20000 IU of vitamin D a day!

If you have a very young child, most infant supplements are found to be 400IUs daily. Upper limit for children less than 1 year old is 1000 – 1500IU daily.

This supplement for kids will be in the liquid drop form and gummies.
