Let’s Talk About Vitamin D

I have always absolutely loved prescribing vitamin D to nutrition patients because of the multiple health benefits, including bone health, heart health, thyroid health, immune support and oral health. There is also some incredible research on how adequate vitamin D can support mood. Let’s take a closer look at this incredible vitamin…

What is Vitamin D?

Vitamin D is a fat-soluble vitamin used by the body for many important processes. Our bodies synthesise vitamin D naturally through adequate exposure to sunlight, or through dietary sources, such as oily-rich fish such as salmon, mackerel, and herring, sun-exposed mushrooms, eggs and dairy products. We love this Cauliflower Pizza recipe for a food-based hit of vitamin D.

How about a supplement?

Around 50% of the population has vitamin D insufficiency as they are not getting enough of this important vitamin through sun exposure and diet alone, which is where a quality supplement may be helpful.

I’m so excited to have just launched our very own JSHealth vegan Vitamin D + Bone + Heart Health formula. It is a “Foundation” range vitamin for a reason, as it really is essential for good health and wellbeing. This therapeutic formula is a great addition to your supplement routine to ensure you have all the vitamin D you need. 

5 of My Favourite Benefits of Vitamin D

Bone Mineralisation

Vitamin D is essential for the absorption of calcium and bone mineralisation, which is positively associated with bone mineral density for healthy, strong bones.

Calcium Absorption

One of the main functions of vitamin D is to increase calcium absorption from the intestines for the development of the bone matrix. Without enough vitamin D, the body absorbs no more than 10-15% of calcium from the diet. When there is enough vitamin D, the body absorbs 30-40% of dietary calcium.

Mood

Research shows that lower levels of vitamin D can negatively impact neural activity in the brain. Vitamin D has been linked with the production of serotonin (the happy hormone) and low levels of serotonin are evident in those with depression. This suggests that vitamin D may improve mood could help relieve symptoms of depression.

Heart Health

Low vitamin D is linked with increased risk of cardiovascular conditions and is also linked with high blood pressure, which is why having enough vitamin D is so key for heart health.

Immunity

Vitamin D plays an important role in immune responses and immune system cells are able to synthesise and respond to Vitamin D.
