Hey Dejuan, Ultra DOES have vitamin Bs in it...not just biotin. I looked at both
Ultra Hair and
Ultra Hair Plus.
Let's look at your plan: If you get B-complex 100mg, I assume you will be getting 100 mg of each B vitamin, but that means you will also get less B5 than you got from Ultra which BTW also provided 100mg of some of the other Bs too. It has 500mg of B5...as well as the other vits you want to continue taking. In other words, two tablets of Ultra are almost the same as taking
a B-complex pill and
a biotin pill and
an L-cysteine pill and
a vitamin C pill and...
Er...do you see where I'm going with this? If you are trying to avoid taking too many pills, then staying with Ultra is one sure way do that. Otherwise find another multi that provides the nutrients you're interested in, in the amounts you want, without leaving out other nutrients good for you. If you wanna take fewer pills without sacrificing your health or that of your hair, I suggest you get an excellent multi like
GNC Multi Ultra Mega Gold Time-Released and then add only biotin, B5 and MSM. The multi will give you everything your whole body/hair needs, including what the B-complex 100mg woulda given you. What's more, you'll also get selenium and C and E and...whatever else you were gonna add or leave out. And you will at least know that all those vitamins are balanced perfectly...so you don't have to worry about overdosing on any of them, and you probably won't feel sick like you've been feeling (just don't take 'em on an empty stomach). And you can trust their absorption will be good since the balance means "complementing not clashing" between the vits... and the time-release characteristic means you won't flush huge amounts water-soluble vits out of your body as soon as you take them. As for the supplements you'll be adding on your own, (ie biotin, B5 and MSM) as far as I know, no toxicity level is known so you can take as much as you want. But if you take too much, the excess will just be flushed out of your system - which is a waste, so don't go buckwild.
Now do you see why I like multis? Why should you use trial and error trying to find the combinations that work best for you when some scientists in white coats have already done all the hard work for you? I think we'd all take less pills (and be safer) if we found a basic multi that was as complete as possible, and then added finishing touches with the safe "usual suspects" like biotin, B5, etc which have no toxicity level. JMHO
