Vitamin D3

Vitamin D3

Vitamin D3 or cholecalciferol is a supplement to prevent and treat vitamin D deficiency. In addition, vitamin D3 is needed to help absorb calcium and phosphorus in the body.  

Vitamin D3 is a form of vitamin D which can be found in several types of food, such as beef liver, cheese or egg yolks, and its formation in the body will be assisted by exposure to sunlight. Vitamin D3 supplements are needed by someone who cannot meet the needs of vitamin D3 naturally.

In addition, vitamin D supplements can also be used to prevent and treat rickets , osteoporosis, or treat low levels of calcium and phosphorus due to parathyroid gland disorders, such as hypoparathyroidism .

Keep in mind that vitamin and mineral supplements are consumed to meet the body's need for vitamins and minerals, especially when the intake of vitamins and minerals from food alone is insufficient.

If you are experiencing a special medical condition, consult your doctor to get the dosage, product type, and duration of use that suits your condition.

Vitamin D3 supplements can be taken before or after meals. However, this supplement should be consumed after meals because it can increase the absorption of vitamin D by the body.

Store vitamin D3 in a place that avoids direct sunlight. Keep supplements out of reach of children.
