Vitamin D3 Dosage for the Immune System

Quickie facts about Vitamin D3:

  • Keep your blood levels above 50 nanograms per milliliter (Ideal range 50-80 ng/ml or higher)
  • More than 3/4 of all US teens and adults fall below 30 ng/ml
  • The government RDA is 400 IU, this is way too low!
  • Most adults need to supplement 2,000 – 5,000IU per day.
  • Get your doctor to test you or order your own Vitamin D3 test. 
  • Milk is not the answer to Vitamin D!
    • For example, a glass of milk has only 100 IU Vitamin D3, you would need to drink 40 glasses of milk to get the recommended amount.

Vitamin D3 and the Immune System

Former CDC Chief Dr. Tom Frieden opinion piece on Fox News: Coronavirus infection risk may be reduced by Vitamin D

Vitamin D supplementation reduces the risk of respiratory infection, regulates cytokine production and can limit the risk of other viruses such as influenza.

A respiratory infection can result in cytokine storms – a vicious cycle in which our inflammatory cells damage organs throughout the body – which increase mortality for those with Covid.

Adequate Vitamin D may potentially provide some modest protection for vulnerable populations.

“This is especially important for people who are Vitamin D deficient – and, surprisingly, that might include more than 40 percent of US adults. People who live in the northern part of the U.S. are at greater risk of deficiency.”

Get Vitamin D3 with K2

Vitamin D frees up calcium. K2 is like a traffic cop, helping calcium move out of the arteries into bones.

Which Vitamin D Supplements are the Best?

The best supplements combine Vitamin D3 with K2 and come in a gel capsule with a quality oil like olive oil. Vitamins D and K are fat soluble vitamins, that is why we prefer olive oil capsules instead of white powder capsules or tablets.

Here are some options for you:

Gel Capsules

  • D3 5,000 + K60 Softgels, (in olive oil)
  • D3 10,000 + K60 Gels, (in olive oil) Recommended when your levels below 40ng/mL or for those with autoimmune conditions

Vitamin D3 Drops (with or without K2)

  • For lower doses choose D3 drops with or without K2
  • Metagenics or Bioclinic Liquid D3 drops, where 1 drop = 1,000IU D3.

Vitamin D3 Dosage for Children and Adults

Recommended supplementation per day based on age:

  • 1,000 IU per day for infants
  • 2,000 IU per day for children
    • Below age 5 years, give 35 units per pound per day
    • Age 5-10, give 2,000 – 2,500 units per day
    • Age 10 – 18, give 2,000 to 4,000 units per day
  • 5,000 – 10,000 IU per day for adults, depending on current Vitamin D levels

Get Tested and Take D3/K2 with Magnesium

How to Dose Vitamin D when sick

I take 5,000 – 10,000 IU per day typically. If I feel like I might be getting sick, I ramp up significantly to 50,000 IU or more, per day, for three days.

Typically at this time of year, most people need 5,000 IU to 10,000 IU per day. If you have not been supplementing, you are probably deficient.

Everyone needs to supplement. This information is critical for people to understand. Get tested, supplement wisely and you will see the benefits in your own life.
