How it supports your body

Many of us don't get enough Vitamin D3 from our diet or by being in the sun. Being deficient in Vitamin D is stressful on our bodies as it is important for the immune system and responding to oxidative stress. People with low levels of Vitamin D are more likely to have more PMS and report worse cramps. There are some suggestions that if you have low Vitamin D, supplementing with it could help reduce PMS symptoms.
