MYTH #1: VITAMIN D IS STORED IN FAT FOR USE

Vitamin D IS fat soluble, but is not stored as a means of maintaining healthy blood levels, so is needed on a regular basis. In fact, the more fat a person has on their body, the more likely they are to have D deficiency.

  • “You don’t need to supplement with vitamin D because it is stored in your fat cells for use.”

Is this true? The fat storage for use debate…

MYTH #2: VITAMIN D IS EASILY TOXIC

Toxicity is rare! It can be seen when taking too much D, such as 50,000 lU/day or more over 6 months or longer. Supplementing is considered safe*; testing D levels is important when taking higher doses.
“Careful not to take too much, vitamin D can be easily toxic.”
Is this true? How much is too much?…
  More information

Almost all who get only the RDA of 400-600 lU/day of vitamin D are deficient! Studies demonstrate the need for roughly 10 times more than the current daily recommendation.

MYTH #4: VITAMIN D TESTING IS UNNECESSARY

There is a higher risk of deficiency among certain individuals (darker skin, higher BMI, older age). Many other factors also influence how each person responds to D, making it useful for everyone to test their levels. Test from home: grassrootshealth.net/test

It is possible to get enough D from sun and food alone (such as for native African tribes and some outdoor workers) but it is very unlikely for most. Nearly everyone requires a vitamin D supplement to avoid deficiency.

MYTH #8: Vitamin D Supplementation Never has Side-Effects

“Vitamin D supplementation has the same safety for everyone”
Is this true? Unfortunately, no. While it is true that the majority of individuals have no issues when taking vitamin D (in fact, many notice improvements in how they feel), there is a very small percentage of people who do experience unwanted side-effects. There are several rare but very real situations in which individuals with certain conditions may experience what seems to be a hypersensitivity to vitamin D supplementation, and sometimes, to the sun as well.

People with Primary Hyperparathyroidism (PHPT), Sarcoidosis, and other Granulomatous Disorders should take extra caution with vitamin D. If you know or suspect that you have any of these conditions, or if you experience what feels like a hypersensitivity or negative effects due to vitamin D, please work with your health care provider to address these conditions, and work with them to safely resolve any existing vitamin D deficiency.
