Does quality matter? I take inexpensive B12 and it sometimes flares my physcosis?
I’ve taken b12 for over 10 years. I noticed nothing.
Quality might matter since B12 can be difficult to absorb for the body. When buying you should look for somthing that claims good bioavailibility.
I started taking vitamins B6 and B12 several months ago and they work great, I feel much better with no side effects! I also tried B8 but that did nothing.
I take B12 every other day . My primary care doctor tested my levels and said they were a little high.
