Vitamin D is considered to be an essential nutrient, and is often associated with sunlight.

Vitamin D provides a number of benefits to the human body including support for the bones, overall mood, amongst other things.

This vitamin forms a part of the ‘24 micronutrients’ which are essential for human survival.

Everyday foods that are rich in vitamin D include fish, eggs, and various dairy products.

It is believed that vitamin D supplementation brings with it a number of benefits, such as improved cognition, better immune health, stronger bones, and a better sense of overall well-being.

Vitamin D supplementation can also reduce the risk of cancer, multiple sclerosis, diabetes and heart disease.

It is quite normal for individuals taking vitamin D supplementation to experience substantial increases in their testosterone levels.

The body itself produces vitamin D with the help of cholesterol and sufficient ultraviolet light from direct exposure to the sun.

Sometimes the sun may fail to provide sufficient ultraviolet light, especially when the UV index is 3 or lower.

The best location to enjoy the adequate amounts of UV index is close to the equator, in between the 37th parallels.

Although the majority of people are not deficient in vitamin D, this does not mean that they enjoy optimum levels.

The Best Way to Take Vitamin D

Vitamin D

The recommended daily amount for vitamin D supplementation is between 400 and 800 IU per day.

Some medical professionals believe that this is too low for grown adults, and instead they recommend up to 2000 IU per day in the United States, and up to 4000 IU per day in Canada.

Recent studies into vitamin D supplementation seem to suggest that the upper safe limit is actually 10,000 IU per day.

Nevertheless, a moderate amount of between 1000 and 2000 IU per day is sufficient enough to meet the requirements of the majority of people.

It is recommended that vitamin D is taken on a daily basis, in the form of meals that are rich in this vital nutrient.
