The Importance of Vitamin D3 Dosage

The recommended daily intake of 10,000 international units (IUs) of vitamin D3 is highlighted as a crucial maintenance dosage for most individuals. While typical recommendations range from 600 to 2,000 IUs, these lower amounts are primarily designed to prevent rickets and maintain bone health rather than support the broader range of benefits that vitamin D offers. Research indicates that over 90% of the population has insufficient vitamin D levels, which can impair immune function, elevate blood pressure, and contribute to conditions such as depression and inflammation. A comparison is drawn between the sunlight exposure needed for vitamin D synthesis and its efficacy, especially emphasizing that even in sunny climates, factors like skin color, geographic location, and lifestyle can significantly affect vitamin D production.

The Case for Daily High-Dose Vitamin D3 Supplementation

Many people only take between 600 to 2000 IUs of vitamin D each day. Did you know that 10,000 IUs of vitamin D3 is only .25 mg?

Vitamin D is the most important vitamin. It controls 10% of your genetics. Over 90% of the population has less than 40 ng per mL of vitamin D3 in their blood. The guidelines of 600 IUs of vitamin D3 are based on preventing rickets, supporting bone health, and managing calcium in the blood, not for the countless other functions of vitamin D.

Low vitamin D levels are caused by people staying indoors, location, skin color, and other lifestyle and genetic factors.

Low vitamin D symptoms include:

•Low back pain

•High blood pressure

•Depression

•Anxiety

•Inflammation

•Poor immune function

Sunblock blocks the absorption of vitamin D. In 1980, society became sun phobic in an attempt to prevent skin cancer, which has continued to increase despite less sun exposure.

You need 10,000 IUs of vitamin D daily, especially for immune function. This amount of vitamin D is the same amount you’d get from 20 minutes of sun exposure in the summertime.

When you get a blood test for vitamin D, they’re not checking for the active form and are not accounting for vitamin D resistance. Many things block the vitamin D receptor and contribute to vitamin D resistance, including genetics, plastics, forever chemicals, age, weight, inflammation, pregnancy, and lactation.

Vitamin D3 won’t work without magnesium. As you increase your vitamin D intake, the demand for magnesium increases. Vitamin K2 and zinc are also vital when increasing your vitamin D dosage.

Vitamin D has potent anti-cancer and anti-tumor benefits at therapeutic doses. It can also combat inflammation and autoimmune conditions. Dr. Coimbra of Brazil has seen positive effects with high doses of vitamin D in people with autoimmune conditions.
