The Mike Dulce Show.

What's up everybody?

Welcome to the Mike Dulce show.

Today we have a brief but very important episode. So I'm going to go straight to my good friend, Dr. Rhonda Patrick. We all know Dr. Rhonda Patrick. She is a multi-time guest on the Joe Rogan Experience podcast. She is the owner of Found My Fitness.

And I'm going to read Dr. Rhonda Patrick's words from her Instagram account.

Now, Dr. Rhonda Patrick says, many of you know that I supplement with 4,000 I use of vitamin

D per day. I just had my levels

of 25 hydroxy vitamin D analyzed, and they are 53 nanograms per milliliter, and I have hovered

around this level for many years. With the recent threat of COVID-19, a respiratory illness, I wanted to share

some data on vitamin D and general respiratory illnesses. I have shared this data a couple

years ago when it was first published, but it seems very relevant to remind people during a time when they will be spending

more time indoors since they have not been making as much vitamin D3 in their skin from

sun exposure. Vitamin D is a steroid hormone that controls the activity of close to 5% of the protein encoding human genome.

Many vitamin D regulated genes are involved in immune function.

A meta-analysis of 25 randomized controlled trials found conducted in 14 countries found that vitamin D supplementation cut the risk

of infection with respiratory illness by 50% in people that were vitamin D deficient and by 10%

in people with normal vitamin D levels.

According to the Endocrine Society, blood levels of 25 hydroxy vitamin D below 20 nanograms per

milliliter is considered deficient.

Less than 30 nanograms per milliliter is inadequate.

Individuals with levels between 30 and 60 nanograms per milliliter are considered adequate.

Meta analysis have shown that people with serum levels between 40 to 60 nanograms per
