Vitamin D3 is a fat-soluble vitamin that is only naturally present in a few foods. Vitamin D is also produced in the body when UVB rays from the sun strikes the skin and triggers vitamin D synthesis.
What is vitamin D3 good for?
Vitamin D3’s primary role is promoting absorption of calcium and phosphorus, which is critical for bone growth and maintenance. Vitamin D3 also plays an important role in the function of muscles and the immune system.
How do I take Puori D3?
It is best to take your vitamin D with a meal.
How do I store Puori D3?
Store your Puori D3 in a cool, dark place as the capsules react to light and heat. Puori D3 comes in dark a dark bottle to protect vitamin D3 from exposure to light.
Where is Puori D3 sourced from?
Puori D3 is gently extracted from a natural source — sheep’s wool. It is then purified and blended with organic virgin coconut oil to ensure maximum absorption.
How does sunscreen affect vitamin D3 absorption?
UVB radiation from sunlight produces Vitamin D in the skin. However, UVB radiation also causes melanoma, skin cancer and photoaging. Sunscreen effectively blocks the UVB rays and protects the skin. Therefore, it might still be necessary to take a vitamin D supplement to reach adequate levels.
Can I get all the vitamin D I need from the sun?
The amount of vitamin D you can get from the sun alone depends on time of day, geographical latitude, the colour of your skin and the amount of skin you expose to sunlight. You produce most vitamin D in the middle of the day when the sun is high in the sky, and the closer to the equator you live, the easier it is to produce vitamin D from sunlight. For example, in Florida your body can produce vitamin D most of the year, while in Denmark or Sweden you can’t produce much vitamin D from September through May. The more melanin you have the darker your skin colour, which works just like sunscreen regarding UVB exposure.
Calcium uptake and bone maintenance
The main function of vitamin D is the hormonal role it plays in regulating the blood level of calcium and phosphorus. Vitamin D increases the intestinal absorption of calcium and the release of calcium from bones to ensure a constant calcium level in the blood.
Calcium is highly regulated and is kept almost constant in the blood for the normal function of the body. Tight calcium regulation is achieved by tapping into the calcium reserve in our bones when our dietary intake is reduced. What this means is that if we don’t get enough calcium in our diet - with the help of vitamin D for absorption - the integrity of our bones can be compromised leading to bone weakness.
Vitamin D is also needed for the mineralization of bones. Children need their bones mineralized as they grow to make them strong and adults are in a constant cycle of bone destruction and rebuilding to keep our bones strong. For this rebuilding process vitamin D is needed. Insufficient vitamin D can lead to Rickets in children where their bones remain soft or osteomalacia in adults where the bones are not sufficiently rebuilt and can break.
Another function of vitamin D is the role it has in the immune system. Many of the cells that are important for an immune response need vitamin D to function. An example is killer cells which target bacteria and viruses.
Vitamin D play a role in muscle function. Vitamin D receptors, which bind to vitamin D are found in the muscle, where it activates the synthesis of protein to maintain and build muscles. Vitamin D also plays a role in the contraction of muscles.
