The American Medical Association states 20 nanograms per milliliter (ng/mL) is a sufficient vitamin D level.

Many modern studies suggest 40 ng/mL is the lowest we should maintain, and that 60 to 80 ng/mL is a much more ideal level.

Personally, l like to keep mine between 80 - 90.  The fear is that D, being a fat-soluble vitamin, could cause hypervitaminosis D.  Dr Harris states he has never seen that happen in his 50 years of practice.

Vitamin D is involved in all the cells and tissues in the body, including your immune cells. All cells need the active form of vitamin D to affect the genetic blueprints within the genes.

Seventy-five percent of American adults and teens are deficient in vitamin D, based on a sufficiency level of 30 ng/ml. Since 30 ng/mL is still on the low end, most are bound to have insufficient levels for optimal health.

Research demonstrates the vitamin D level of 40 ng/mL lowers your risk of cancer by 67%, compared to having a level below 20 ng/ml.

A vitamin D level above 60 ng/mL lowers your breast cancer risk by more than 80%, and a level of 40 ng/mL lowers the risk of premature birth by 60%. There’s also a strong inverse relationship between vitamin D and other cancers, including colorectal cancer, which is the third leading cancer killer in the U.S.
Vitamin D affects the biology of the cells and their activity throughout the body. Therefore, D can be involved in a wide variety of dysfunctions and labeled diseases from fetal development, heart disease, diabetes, lung disease, premature births, and the formation of cancer.

According to a study in Anticancer Research, it would require 9,600 IUs of vitamin D per day to get a majority (97% of the population) to reach 40 ng/mL. The average American gets nowhere near this level unless they are supplementing.

GrassrootsHealth, through its D*Action study, found up to six times variability in achieved serum levels.  Therefore, one person taking 5,000 IUs of vitamin D per day may achieve a level of just 20 ng/mL while another is able to reach a level of 120 ng/mL taking the same amount. This is one reason OHS uses predigestion to allow for maximum absorption.  It is important we test at least two times per year to make sure are levels are adequate.

According to data published in the Archives of Internal Medicine, 75% of American adults and teens are deficient in vitamin D, based on the low level of 30 ng/mL.

Many studies have shown people with higher vitamin D levels have a far lower risk of a wide variety of internal cancers.  In summary, the research has demonstrated that serum vitamin D levels of 40 ng/mL, diminishes cancer risk by 67%, compared to having a level of 20 ng/ml or less. Research shows most cancers occur in people with a vitamin D blood level between 10 and 40 ng/mL. The optimal level for cancer protection has been identified as being between 40 and 60 ng/mL.

Vitamin D in adequate levels also increases your chances of surviving cancer if you have it.  This includes melanoma, the most dangerous form of skin cancer. There is also evidence vitamin D can improve treatment outcomes. For example, adding vitamin D to the conventional treatment for pancreatic cancer was found to boost the effectiveness of the treatment.

It also plays a significant part in protecting you from COVID-19 and protects you from autoimmune diseases. Vitamin D Deficiency has been linked to colorectal cancer.  In a 2018 study, researchers found an inverse relationship between vitamin D and colorectal cancer, which in 2022 is the third leading cancer killer in the U.S. The vitamin D levels of 5,700 colorectal cancer patients in the U.S., Europe and Asia were compared to 7,100 cancer-free controls.
  • People with a vitamin D level of 12 ng/mL or below had a 31% higher risk for colorectal cancer compared to those with levels between 20 and 25 ng/mL
  • Those with levels between 30 and 35 ng/mL had a 19% reduced risk for colorectal cancer
  • Those with levels between 35 and 40 ng/mL had a 27% reduced risk
  • For each 10 ng/mL increase in circulating vitamin D, the risk for colorectal cancer was reduced by 19% in women and 7% in men
We could keep citing research on vitamin D for many more pages but let us suffice to say adequate levels of vitamin D crosses many borders to allow us to have better physiology, with increased health and wellness.

OHS has Vitamin D in many of the synergistic formulas and Paks.  If wanting to increase bone density and help remove unwanted calcium deposits, consider DAK1K2 developed by Dr Marc Harris.

This is my favorite D and is what I take and recommend most often.

For elevating vitamin D also consider Longevi-D K2, which also contains CoQ10 (Ubiquinone-Fermented) and acerola cherry in a Cultured Media Blend and Opti-Blend Delivery System.
