Vitamin D is one of the most common vitamin deficiencies seen in the medical practice although levels are rarely checked. The majority of my patients from New Jersey to San Diego are vitamin D deficient. I want to share with you why and how you can easily solve this problem.

1. Fatigue

Vitamin D 2000 units daily at night can improve energy levels. The deficiency is rampant and easily remedied with over the counter supplements, specifically Vitamin D3 2000 units daily at night with dinner. Studies have shown a direct connection with improved muscle weakness, improved mood, improved sleep, and improved metabolism.

2. We Are Always Indoors

The Sun provides us with light, energy, nutrients but as we’ve evolved to be indoors more, we’re less exposed. This can be helpful in reducing risk of skin cancer but can also leave you deficient in nutrients, including Vitamin D. Today, we sleep indoors, work indoors, and simply don’t spend enough time outdoors to rely on it as a source of Vitamin D. This is why supplementing is essential and easy to do with over the counter products. At times a prescription is recommended for higher dose if your Vitamin D levels are extremely low.

3. Cancer Risk Reduction

Vitamin D deficiency increases the risk of colorectal cancer, breast cancer and prostate cancer. A recent study found vitamin D deficiency increases the risk of colorectal cancer, especially in women.

4. Lactose Intolerance or Milk Disinterest

In order to obtain enough vitamin D from milk you have to drink an exorbitant amount. You also have to be lactose tolerant which the majority of people are not.

The majority of the world is lactose intolerant. An alternative to milk is almond milk but the Vitamin D levels do not compare.

5. Vitamin D Levels are Rarely Checked

This one’s not completely true. You can check your vitamin D but your insurance company probably won’t pay for it. If you can I recommend asking your doctor to check your vitamin D levels before supplementing but if you can’t, supplementing with 2000 units daily can help you with fatigue, colon cancer risk reduction, immunity, metabolism, and mood.
