Understanding the Benefits

Many of us fall short of Vitamin D3, whether from diet or sunlight. Yet, Vitamin D is vital for our immune system and tackling stress. Interestingly, low levels of this vitamin have been associated with more severe PMS symptoms and cramps. Supplementing with Vitamin D could help alleviate PMS symptoms, especially if you're deficient.
