Itâs no secret that I love being in the sun âď¸ it always makes me feel great and studies show just how important it is for our longevity.
Thereâs been so much conjecture on sun exposure but thereâs been little focus on the importance of Vit D3 and its benefits.
First, I want to get one thing really clear - sun protection is absolutely important - but so is exposure to Vit D3.
Up to 50% of adults are deficient, especially women over 40 and those living in less sunny climates or working indoors.
Vitamin D3 is not just a vitamin itâs a prohormone that controls over 1000 genes linked to immunity, inflammation, bone health, mood and longevity.
Multiple studies have shown that Vit D3 deficiency can increase dementia risk by 80%! Thatâs a whopping number. While people that supplement with Vit D3 have a 40% REDUCED risk of dementia.
Low levels are also associated with increased risk of:
- osteoporosis and fractures
- impaired immune response
- higher rates of autoimmune disease
- mood disorders like depression and anxiety
- impact white brain matter
- accelerated biological ageing.
Your body can make Vit D3 from sunlight, but age, sunscreen, darker skin tone and even gut health can reduce absorption.
By getting a blood test you can easily check your levels to ensure you arenât deficient.
