Let's talk vitamin D3!
Vitamin D helps in the production of estrogen, progesterone, and testosterone by acting as a prohormone in steroid and thyroid hormone production. It helps keep hormonal balance in women, especially during menopause and low vitamin D levels can contribute to those hormonal imbalances, like hot flashes, mood swings, and irregular periods.
Vitamin D is also involved in the metabolism of our thyroid hormones (T3 and T4) which are needed for metabolism, growth, and development.
Vitamin D also helps in the production of parathyroid hormone (PTH) which regulates calcium levels in the blood, making sure these levels are in a healthy range.
Vitamin D may also be involved in regulating insulin levels
by helping improve insulin sensitivity and reducing the risk of type 2 diabetes.
It may also be involved in the process of creating other hormones, such as cortisol, DHEA, and growth hormone.
We make our own vitamin D every time we walk our dog outside or watch our kids on the weekend play sports. However, if you feel you don't have enough vitamin D, you can supplement. It is fat soluble which means it stores up in the body. Nikki recommends taking 1,000-2,000IU vitamin D3 daily or if you are taking the 5,000IU vitamin D3 with K2, Nikki recommends taking that every other day to ensure your vitamin D levels don't get too high. If you're interested in testing your vitamin D level, just ask Nikki to add it to your hormone labs the next time you are in the clinic.
