Kirkland (Costco) Multivites give me a real gut ache (no joke - I've heard others say the same.) The nice thing is you can break them in two, and save money plus not get the gutache.
I honestly function the same with and without vitamins - but I'm pretty rigorous about eating good food.
They give me a gut-ache, too, but every multi-vitamin I've taken has done this. I've just come to accept it as a necessary evil.
Why would you split the vitamins in half? Wouldn't that mean you're only getting half the ingredients per dose?
Stay away from GNC multi vitamins.
They smell like dog pooo and they will give you an upset stomach. Plus they are very expensive.
My brother left a bottle at my house and I tried them for a week. I think I would have less stomach pain if I drank sewer water from a 3rd world country.
The only ones that ever upset my stomach, and I've got a delicate stomach, were these mega-packs from Sam's Club. About 1000% of your daily requirements and I'd get all flushed when I took them. Found out later that was from all the niacin. If I broke them up and took 3 then in an hour or two the other 3, then I was okay.
I think the vitamins that upset the tummies contain too much of something, maybe zinc or iron.
I take Nature Made multi's or One-a-Day, or Centrum, or whatever for a multi, then two or three 1200 mg fish oil caps-also Nature Made, and sometimes an extra B-complex, and potassium if I'm running and/or sweating a lot.
Did a LOT of Web peeking regarding glucosamine.
Unlike many supplements, I did not find any 100-percent "No, the stuff is phony" comments.
I did read that the research is inconclusive but that some folks may benefit to a certain extent from the stuff.
No apparent adverse affects to speak of. Of course, mega-doses of anything can be bad!!!! Even vitamins proven good for you can cause severe, even deadly problems, if too much is ingested for too long.
I believe vitamin E was one of the dangerous ones if way too much is thrown down the throat.
Wouldn't hurt to try the stuff. If I remember right, not all brands are created equal with some brands containing more of the active ingredient.
Might behoove you to search the Web for the full story.
