Description
Vitamin D is responsible for a multitude of biological functions, all of which are essential for overall health and well being. It regulates the amount of calcium and phosphate the body can absorb, both of which are needed for healthy bones, teeth and muscles. It also enables our blood to clot, our muscles to contract and our hearts to beat!
Our body’s main source of vitamin D is produced as your skin absorbs ultraviolet rays from direct sunlight. Despite this ability to make this crucial nutrient ourselves from the sun, an estimated 75% of people are deficient. Many factors affect the skins ability to produce vitamin D, including; time of day, skin colour, sunscreen and age.
The UV rays that help our bodies produce Vitamin D are the same rays that cause sunburn, which can lead to cancer. Although the sun is a valuable source of natural vitamin D, you must achieve a healthy balance where you can to prevent sunburn.
When the ultraviolet rays come into contact with our skin, they convert 7-dehydrocholesterol (7-DHC), a substance present in our skin, into pre-vitamin D3. The amount that is converted depends on the amount of time spent in direct sun and the melanin in our skin. Melanin is a pigment that gives skin its colour and is produced by cells called melanocytes. It provides some natural protection against sun damage, and the melanocytes increase their production in response to sun exposure.
After pre-vitamin D3 is produced, it is converted into vitamin D3. Then in the liver and kidney it is converted into active Vitamin D3. This biologically active form is also known calcitriol and it regulates the absorption of calcium in three different ways:
It stimulates your intestines to absorb
calcium from foods you eat or from supplements- It works in your kidneys to help recycle
calcium that would have otherwise been excreted - It regulates storage of calcium and the
process of bone building
Vitamin D is an essential nutrient that has great health benefits, but to accomplish these benefits vitamin D levels need to be maintained in a certain range. The majority of adults struggle to obtain and maintain sufficient vitamin D levels. Vitamin D is not present in many foods so our main source of vitamin D is reliant on sun exposure. This is problematic for most people for numerous reasons:
This is why Public Health England recommends a daily Vitamin D3 supplement to be taken by all. Including pregnant and breastfeeding women.

I jumped on these during covid after seeing some articles about those with vitamin d deficiencies being likely to end up in hospital with covid. Im 64 and never bothered with vitamin D in the past. The difference I felt, I can only assume ive been deficient most my life. Literally gave me a new lease of life as an elderly lady with not great health. Also noticed ive not been getting ill as frequent. Life saver!

Crazy how people buy vitamin D from big sellers like Holland and barrett that provide next to no vitamin d, literally a waste of time. After a little research I came across these. Only manufacturer who provides loads of information about the product as well as the product being super strong. Highly recommended.

Diagnosed with a defiancy after a blood test. Chose this product because you can take the tablets with the patches and spray for a big boost. Doctors confirmed my levels are excellent when I went back 3 months later. Will continue to use just the tablets now my defiancy has been corrected.
