Vitamin D Benefits

What’s So Important About Vitamin D?

Here are our clinic’s two specialized interests in Vitamin D:

  1. High levels of Vitamin D enhance tissue growth in our PRP Stem Cell Joint Repair process. Read more.
  2. Vitamin D gradually lessens overall pain and muscle weakness. Read more.

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.

A study of nearly ten thousand people confirmed that Vitamin D reduces inflammation in 25 different diseases.

No Covid deaths with Vit D blood level of 50 or greater. There is “Evidence that Vitamin D Supplementation Could Reduce Risk of Influenza and COVID-19 Infections and Deaths“. And, click here for more about Covid-19 and Vitamin D. And, most recently determined, Vitamin D and Vitamin K2 status reduce severity of Covid-19. Even a meta-study with nearly 2 million people shows that building up Vitamin D in your body reduces the risk of infection and the risk of severe symptoms and death.

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, treating pain, 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 no longer founded concern about levels above 100.


We recommend taking Vitamin D3 every single day. Some doctors prescribe very high doses of D on a weekly or monthly basis. This may work for helping bones. However, there is an entirely different system in the body that needs daily dosing, and this includes the system of repair, as in PRP Stem Cell Joint Repair. Here is a scientific talk on why daily dosing is needed.

Doses up to 40,000 IU/day or 280,000 IU/week are safe, according to important peer reviewed research. A Mayo Clinic publication says that you would need to take over 50,000-100,000 IU per day for months or years to create Vitamin D toxicity. Here is another summary of the myths around Vitamin D toxicity. Instead, many people are on doses that are far too small. We commonly recommend 15,000 IU/day for patients during the process of PRP Stem Cell Joint Repair, and that exact dose has specifically been found to be safe in 2017 research. Many doctors are simply unaware of this scientifically sound, newer research, and they may tell you that our recommended dose is too high, or that our target lab test blood level is too high. Don’t believe them! Print out the research studies at the three above links and literally hand the studies to those doctors!

A recent study demonstrates that deficiency of Vitamin A also impairs stem cell function. Vitamin K2-7 (MK-7) is a valuable partner for higher doses of Vitamin D3 because it directs calcium into appropriate locations such as bone, treating osteopenia/osteoporosis, and reducing chances of calcium accumulating painfully in rotator cuff tendons, knees and other joints. You are encouraged to share the link for this scientific slide show about Vitamin K2-7 with a doctor who might be following you for osteopenia or osteoporosis.

We recommend that you take three little gel caps of this product, every single day. Or you can take one little capsule of this product, plus one little capsule of this product. Take it anytime during the day, but some research has shown that it could be 50% more effective taken with your biggest meal of the day. Don’t miss a day. Don’t increase or decrease the dose. Keep it constant. Consider taking Vitamin C such as this, and a magnesium supplement such as this to  increase your absorption of Vitamin D. Maybe after about a year, have your blood tested, as discussed above.
