Vitamin D is one of the 24 micronutrients critical for human survival. The sun is the major natural source of the vitamin D, but vitamin D is also found naturally in foods such as fish, dairy and eggs.
Vitamin D plays a vital role in a number of key functions within the human body, these include supporting cell growth, reducing inflammation, absorbing calcium and promoting bone health.
Supplementing with vitamin D is associated with a wide range of benefits, including increased cognition, immune health, bone health and well-being. Supplementation can also reduce the risks of cancer, heart disease, diabetes and multiple sclerosis. People deficient in vitamin D may also experience increased testosterone levels after supplementation.
Lack of Vitamin D has also been linked to muscle weakness, fatigue, and even mental health. Studies have shown that Vitamin D deficiency can contribute to an impaired immune system, making it more difficult to fight infections. Vitamin D receptors in our brains help brain cells receive and understand chemical signals- a lack of Vitamin D is likely to affect the way our brain communicates.
Most people are not considered to be deficient in vitamin D, however most people are not considered to have optimal levels of vitamin D either. Due to the many health benefits of vitamin D supplementation is encouraged if optimal levels are not present in the body.
How much Vitamin D do you need?
The current recommendation for Vitamin D is currently set at 400-800IU /day, but this is too low for adults. The safe upper limit in the United States is believed to be 4,000IU/day. However the latest research suggests that the true safe upper limit is 10,000IU/day.
For moderate supplementation, a 1,000-2,000IU dose of vitamin D3 is sufficient to meet the needs of most of the population. This is the lowest effective dose range.
Vitamin D3 supplementation (cholecalciferol) is recommended over D2 supplementation (ergocalciferol), since D3 is used more effectively in the body, so be sure to check which source you are supplementing with.
Each Força Fuel D3 tablet contains 5,000IU of D3, which means daily supplementation isn’t necessary if you’re trying to achieve optimal levels of vitamin D.
