Hi Arx;
I'm glad that NOW brand works wll for you. I would like to be able to recommend brands to people that are easy for them to find. With family, friends, and neighbors, it's too complicated to recommend the more obscure brands.
Before 5yrs. ago, I was taking Twin Labs cyanocobalamin subs. It was all I could find in stores. I was uneasy about it even then.
When I began methylcobalamin, close to 5 yrs. ago, I started with Jarrow's,luckily.
About a year ago, I tried to find a type without fillers and flavorings, and tried Bio-Alternatives brand, which contained only methylcobalamin and purified water. I began to tank on it.
I have some Holistic Health brand and Perque brand hydroxycobalamin. I think they are excellent for people who can make the conversion from inactive B12 to active B12. I seem to have trouble converting, so I'm back with the methyl-B12.
I have some ET brand, and I believe it works well. My husband combines it with the AOR brand. Even though he doesn't have CFS, he has realized that he has some milder neuropathy and other symptoms that are relieved by taking B12. ( He discovered this when the Jarrow's changed.)
Thanks for letting us know that the NOW brand is also effective, Arx.
