Vitamin D – the mood-boosting sunshine nutrient
-Sep 4, Jenny Paul , Health -
Vitamin D is a fat-soluble vitamin which is essential for normal growth and development. We’ve included this master nutrient in Lumity’s Morning & Night supplements, so here’s a closer look at why.
It has become very newsworthy recently because many adults are believed to be deficient in this essential vitamin. This is because so many of us live in countries that aren’t naturally very sunny.
Season, time of day, length of day, cloud cover, smog and skin melanin content are among the factors that affect UV radiation exposure and vitamin D synthesis.
Few food sources provide sufficient vitamin D, so sunlight exposure or supplementation is important.
However, low exposure to the sun or exposure exclusively with thick, high SPF sunscreens means that this source of vitamin D can be very low, and supplementation is required to provide sufficient vitamin D for all the body’s needs.
What is vitamin D and what is it used for?
Vitamin D is required for the absorption and metabolism of calcium and phosphorus to support the necessary hardening of bones.
Its role in the absorption of calcium is also key for a healthy neuromuscular system, muscle strength, normal blood clotting and heart function.
It is also considered to be helpful with seasonal depression.
Which foods contain vitamin D?
Whilst spending time in natural sunshine is a great way to boost your vitamin D levels through cholesterol in the skin, it does occur naturally in some foods.
Fish, including salmon, sardines, mackerel and tuna are all sources of vitamin D, holistic nutritional wellness coach Naomi Buff says.
“If you’d like to boost your vitamin D levels through diet, try eating more fish. Oily fish like sardines, salmon, tuna, mackerel and caviar are all rich in vitamin D.
“A teaspoon of cod liver oil contains plenty of vitamin D.
“If that doesn’t sound appealing, eggs, raw milk and mushrooms also contain this nutrient.”
What are the benefits of vitamin D?
Vitamins A and D taken together have been shown to reduce the incidence of colds, reduce muscle spasms (especially when related to anxiety states) and ease asthma and arthritis.
Studies have shown that omega fatty acids and Vitamin D are associated with longer, healthier telomeres. With each cell cycle, telomeres, the protective caps at the end of chromosomes, shorten. When telomeres become too short, the cell dies.
FAQ: What is the recommended dosage of vitamin D?
Lumity contains 15 µg of Vitamin D3 which is over 300% of the RDA. Taking too many vitamin D supplements over a long period of time can cause too much calcium to build up in the body (hypercalcaemia). Consult a doctor if you have any questions about your own Vitamin D supplementation.
