Some of the benefits of Vitamin D3:
- Supports immune system
- Supports a healthy heart and cardiovascular system
- Promotes healthy energy levels and endurance
- Promotes well being
- Supports cognitive function and a healthy brain
D3 is a vitamin derived from 7-dehyrocholesterol, however it acquires a hormone like action when converted to1.25-dilhydroxy or calcitriol by the liver and kidneys. As a hormone calcitriol controls, phosphorus, calcium, bone metabolism along with neuromuscular function.
The RDA of Vitamin D is set at very low levels and apparently came into being from what I have read to prevent a very painful bone disease called (osteomalacia) and rickets. The RDA (recommended daily amount) or RDI recommended daily intake is set at between 400-600 IU. Too low a dose of vitamin D3 has also been implicated in symptoms such as back pain, depression, insulin resistance , cancer, and immunity disorders.
Some newer studies have elevated the upper intake limits on vitamin D3 to 10,000UI daily. I am NOT a doctor and NOT giving medical advice, however I have been taking 5000IU of vitamin D3 for about 5 years now and probably get another 1000-1500IU in my food intake and multi-vitamin supplement.
