Vitamin D

Vitamin D, the sun vitamin, actually gets converted into and acts like a hormone in our body. It is produced when we expose our skin to UVB radiation from the sun. Vitamin D is very important in overall immunity and plays a big role in protecting the lungs from injury. Low levels of this vitamin in the body have been found to be correlated to a higher mortality rate from respiratory infections. Vitamin D affects serotonin production in the brain and also moderates inflammation in the gut. It has even been shown to regulate the aging process.

.

Many aspects of our modern life get in the way of optimal vitamin D production. We spend most of our time inside and when we are outside we wear clothes and sunscreen. Vitamin D deficiency is common. Especially amongst people of darker skin tones living far away from the Equator where UVB exposure is much lower. The darker our skin, the longer it takes us to produce vitamin D, and the more sun exposure we need to reach optimum levels. Supplementation is recommended to most people living in colder countries where sun exposure is very low during several months of the year. The recommended adult daily allowance value for vitamin D is 600 IU/day, which is a very low dose and may not be enough to correct deficiency. The upper tolerable level is 4000 IU/day. To find the right amount for you consult with a qualified practitioner such as a nutritionist, naturopath or medical doctor.

During spring and summer, get outside and expose the most amount of skin you can to the sunlight (without a sunscreen) for a minimum of 15 minutes a day. Be responsible, if you are going to spend a lot of time in the sun, risking getting sunburned, please wear sun protection after a limited amount of unprotected exposure. Happy sun bathing ☀️
