Vitamin D is your inner sunshine. Without enough D, you can feel tired, depressed, and fatigued. It’s necessary in the production of calcium, immune system support, and bone and joint health.
Unfortunately, it’s next to impossible to get enough Vitamin D from fruits and vegetables. Mushrooms are the only vegetable with naturally occurring Vitamin D but don’t provide enough of the necessary daily intake. We recommend everyone take supplements during the winter, especially vegetarians and vegans.
The National Institute of Health Office of Dietary Supplements recommends that anyone up to age 50 intake 5 micrograms or 200 IU per day.

• Muscle pain and loss of muscle strength
