What supplement makes you worse and what do you do about it?
This last week I experienced a die-off effect for about two days that I think was related to something I ate. As a result, I became hypersensitve to the sublingual vitamin B12 that I take - 2000 mcg three times a day.
The effect was that for about two hours after taking B12 I would get a tingling, painful feeling in my upper back and lower neck, just the left of center. It was not numb but felt like it was vibrating. I backed off the B12 for a couple of days until it passed.
Vitamin D will also occassionally give me a runny nose for a hour or so after taking it. It's just an annoyance so I don't alter my dosage of that.
So my question is: what supplements worsen your sypmtoms? And do you back off, or just plow through it? Is there anyone that increases that supplement?
