Vitamin D3
60 Vegan Capsules (1-Month Supply)
Item# RTX-DS0600-060

Vitamin D3, also known as the sunshine vitamin, is required by the body to carry out essential functions and to maintain proper health of the system. The human body has the capability of synthesizing vitamin D3 on its own with the help of the sun. This requires exposure of skin to sun’s radiations for a particular period. Vitamin D3 is found to be abundant in fish, eggs and meat.1 Rejuvenation Therapeutics’ Vitamin D3 comes in a capsule loaded with the required amount of vitamin D3. It is gluten-free and has no artificial fillers or rice. It is completely suitable for vegans.

Vitamin D3 and bone health
Vitamin D3 plays a very significant role in the absorption and metabolism of calcium and phosphorous. Calcium and phosphorus are essential for bone and teeth health. Deficiency of vitamin D3 will prevent the absorption of calcium from the diet into the body resulting in fragile bone health.2 Studies show that an intake of 800 IU a day reduces the risk of bone health related issues.3

Vitamin D3 and immune health
Vitamin D3 production is directly related to the level of exposure of our skin to ultraviolet B radiation of the sunlight. Research indicates that children who were exposed to sunlight have better immune health.4 Low level of vitamin D3 in adults corresonds higher risk of immune health issues.5

Vitamin D3 and cardiovascular health
In a study conducted among 50,000 men over a period of 10 years, it was found that men who were deficient of vitamin D3 were twice at risk of poor heart health compared to men with optimal levels of vitamin D3.6 There are vitamin D3 receptors in the heart,7 through which vitamin D3 promotes a healthy inflammatory response in the cardiovascular system.8

It is almost impossible to receive the required amount of vitamin D3 only through sunlight and diet. Dosage of 5000 to 6000 IU is required to bring the serum 25OHD levels greater than100 nM/l. This can be efficiently obtained by supplementing your diet with Rejuvenation Therapeutics’ Vitamin D3.
