The Important Role of Vitamin D – Beyond Immune and Bone Support

Vitamin D is an essential nutrient well known for its role in immune function, bone metabolism, and reduction in cardiovascular diseases. However, there are other less-known effects of vitamin D that this lecture will explore, including its influence on cellular metabolism linked to mitochondrial activity and neurochemical regulation within the nervous system.

Q: What to do if serum vitamin d level is really high, in 400’s for example?

A: You need to check their sources of Vitamin D and look to cut back. Just because the levels come back high like this does not automatically mean the individual is toxic, but the longer times goes on it could become a problem.This is where repeat testing is important.

Q: Please discuss systemic dangers for levels above 80-100ng/ml

A: I did discuss this in the lecture. Hypercalcemia, bone problems, e.g., pain, kidney problems, including kidney stones. 

Q: Why did the child with total D of 153 have all in the D3 category if you stated that they were supplementing that made it elevated, if D3 is from sun exposure? 

A: Diet/supplements can go to Cholecalciferol (D3) too. Here is a diagram:

Q: What do you think of Vitamin D injections? 

A: I have not used them.

Q: I have a client with high serotonin on neurotransmitter test, so this can be caused by gut inflammation, and can be corrected by vitamin D, is this right? 

A: It is more likely that the high serotonin is from something else such as supplements like tryptophan, 5-HTP, or even medications such as SSRI’s. There are certain foods that can generate serotonin too such as eggplant and bananas.

Q: What if you have the VDR SNP? How to manage? 

A: You need to test an individual’s Vitamin D levels, along with varying dosages of Vitamin D to maintain their level is the optimal range. In a situation like this running a test every 6 to 8 weeks for a period time can be done to get the levels consistent in the healthy range.

Q: Do you test animals? Dogs and cats? 

A: No.

Q: Not sure if addressed; which level should be checked? 25 (OH)d or 1,25 (OH) 2d? 

A: 25(OH)D since it has a longer half-life than 1,25(OH)D. The 25(OH)D is a good indicator of overall Vitamin D status.
