Vitamin D Benefits

What’s So Important About Vitamin D? Our clinic’s pain-related special interests in Vitamin D:

  • Chronic pain is associated with low Vitamin D.
  • High levels of Vitamin D make growth factors work better with our PRP Stem Cell Therapy.

Other medical conditions that can be prevented or treated by high levels of Vitamin D:

Cancer Hypertension Heart disease
Autism Obesity Rheumatoid arthritis
Diabetes Multiple Sclerosis Crohn’s disease
Cold & Flu Inflammatory Bowel Disease Tuberculosis
Septicemia Signs of aging Dementia
Eczema & Psoriasis Insomnia Hearing loss
Muscle pain Cavities Periodontal disease
Osteoporosis Macular degeneration Reduced C-section risk
Pre eclampsia Seizures Infertility
Asthma Cystic fibrosis Migraines
Depression Alzheimer’s disease Schizophrenia


  • Inflammatory arthritis is reduced by high blood levels of Vitamin D3.
  • Vitamin D3 helps prevent cognitive decline and may even be capable of reversing the plaques in the brain seen in Alzheimer’s disease.
  • High levels of Vitamin D3 reduce many cancers by 50%.
  • High oral doses of Vitamin D3 are far better than the flu shot.
  • Vitamin D helps people with diabetes, and helps prevent diabetes.

The above list is taken from Dr. Joseph Mercola. Dr. Mercola goes on to say that:

Researchers have calculated that simply increasing levels of vitamin D3 could prevent diseases that claim nearly 1 million lives throughout the world each year.

We commonly help people with knee pain, most of the time associated with wear of parts in the knee, also known as osteoarthritis. The knee pain gradually reduces strength of the quadriceps or thigh muscles which are key to recovery. Vitamin D is linked to such osteoarthritis and thigh muscle weakness in studies such as this article, this article, and this article, while this article studied both knee and hip pain.

Sources of Vitamin D:

  • Correct Vitamin D source: sunshine.  While there appear to be scientific advantages to getting Vitamin D through sunshine, getting enough is difficult. You have to expose most of your skin to sun between 10 AM and 2 PM through most of the year. And, you have to get just a bit pink and not burn your skin. As a result, even most residents of the Hawaiian island of Maui test as deficient.
  • Correct Vitamin D supplement: Vitamin D3 or cholecalciferol.
  • Incorrect Vitamin D supplement: Vitamin D2 or ergocalciferol, the synthetic Vitamin D in milk and prescription Vitamin D – much less effective.


  • We encourage lab testing of your blood to check Vitamin D3 levels periodically. Here are the goals:
  • Blood test normal range: 40-60 ng/ml according to a scientific panel of 48 Vitamin D scientists organized by
  • Blood test therapeutic range: 60-80 ng/ml, or more, for preventing cancer, treating illness, or supporting our tissue regeneration procedures. See this peer reviewed journal research study.
  • Many wholistic physicians try to have all their patients be above 100 ng/ml. The research study noted above has determined that blood levels up to 200 ng/ml are safe, though labs and most physicians still express concern about levels above 100.


Doses up to 40,000 IU/day or 280,000 IU/week are safe, according to important recent peer reviewed research. Many people are on doses that are far too small. We commonly recommend 15,000 IU/day for patients receiving PRP Stem Cell Therapy, and that dose has specifically been found to be safe in 2017 research.

Dr. Joseph Mercola makes the case that Vitamin D3 should ideally be taken together with Vitamin A and Vitamin K2-7, also known as MK-7. A recent study demonstrates that deficiency of Vitamin A also impairs stem cell function. Vitamin K2-7 (MK-7) also directs calcium into appropriate locations such as bone, reducing chances of it accumulating in rotator cuff tendons, knee joints, and other places that calcium deposits can cause pain.
