Do You Need to Take Vitamin D Supplements?

Recently, major studies into the effects of Vitamin D have concluded that the public do not need to supplement with Vitamin D. This conclusion is based on the findings that there is no proven health benefit of taking Vitamin D to improve bone health. This may cause a lot of people to say adios and throw away their supplements, but hold your horses, as supplementing with Vitamin D is essential for a range of other health benefits too!

What is Vitamin D?

Vitamin D is a fat-soluble vitamin that helps regulate the amount of calcium and phosphate in your body. It also plays a vital role in overall health of all individuals.

Why Should You Take Vitamin D Supplements?

The major study on vitamin D discourages the UK population from taking Vitamin D supplements because trials show that it doesn’t present any benefit in protecting against falls and fractures. However, supplementing with Vitamin D produces a whole host of other health benefits. Vitamin D can help with:

  • Your pelvic floor – Vitamin D helps maintain strong pelvic floor muscles and normal bladder function. The Vitamin D receptor is found in the detrusor wall (muscle of the bladder), and insufficient levels may impact bladder function. A lack of Vitamin D can lead to weaker pelvic floor muscles which can cause your pelvic organs to droop from their naturally elevated position. Vitamin D can help fight against this muscle degradation. There is also a strong correlation between women who suffer from pelvic floor disorders and Vitamin D deficiency.
  • Vulvodynia – Women with vulvodynia often lack essential nutrients for the vulvar, vaginal, and pelvic tissues to function optimally; one of these deficiencies is Vitamin D.
  • Vaginal Dryness and Atrophy – Vitamin D is effective in decreasing the pH and dryness of the vagina and improving cell health.
  • Endometriosis – There is a correlation between low Vitamin D levels and endometriosis. Vitamin D can help to reduce inflammation.
  • PMS – Vitamin D can reduce PMS side effects such as irritability, anxiety and sadness.
  • Heart Disease – Low Vitamin D levels can increase the risk of heart disease.
  • Testosterone Levels – Vitamin D deficiency is linked to testosterone deficiency.

Natural Sources of Vitamin D:

The main source of Vitamin D comes directly from sunlight. From late March until the end of September, you should receive your daily dose of Vitamin D from the sun every day. The body can create Vitamin D from direct sunlight on your skin when you are outside. However, between the colder months of October through to early March, you don’t receive enough vitamin D from sunlight.

Vitamin D can also be found in several foods, including:

  • Fish – such as salmon, herring, sardines, mackerel and fresh tuna
  • Red meat
  • Liver
  • Egg yolks
  • Fortified foods (foods with added nutrients) – such as most fat spreads and certain breakfast cereals

Remember that supplementing with Vitamin D can help you to improve and maintain a variety of health issues, not just bone health. Take a look at Kegel8’s supplement range to find out what vitamins and minerals can help you!
