Anxiety after Taking Both Vitamin D and Fish Oil

by Martin

I've noticed that when I take 5000mcg of vitamin D3 at night I feel far more anxious than usual, even a little confused. and not with it. I also get that response to fish oils, so is it worth me looking for non fish D3?

And I will increase my magnesium after reading this page though as I'm not getting enough for sure. Thanks for the easy to read information on your site!

Probably Rancid Oils..
by: Kerri Knox, RN- The Immune Queen!

Hi Martin,

Yes, do increase your magnesium as that would be the first thing to suspect when getting an anxiety reaction after taking vitamin d as I've outlined on the Magnesium and Vitamin D page.

But it's VERY curious that you have the same reaction with fish oils. I really doubt that that is the issue with your vitamin d because the VAST majority of vitamin d products are already made from lanolin. I tried to find someone a vitamin d without lanolin and it was NOT easy.

What I DO suspect is that, at lease in your Fish Oil Supplements and maybe your vitamin d too, that the oil has gone rancid and that is what is giving you a hard time. Rancid oils in supplements is a BIG problem and unless you use VERY high quality supplements- particularly with fish oils that go rancid easily- then you'll almost certainly get rancid oils or Polyunsaturated Oils that your body is not liking you to be eating.

So, for vitamin d, I'd suggest switching to a DRY Vitamin D3 Supplement and spending the extra money on a HIGH Quality Omega 3 Fatty Acid Supplement such as the Omega 3 Supplements that I offer on my site

If you get it in capsules, it's CRITICAL that they guarantee that they are fresh and of the highest quality, or you can get it in a liquid and that way you are able to smell it yourself.

Hope this helps...
