Chewables, and those that dissovle in water might work. Otherwise, figure out what part of a multi-vite makes you nauseous- it could be the Iron, B Vitamins (B1, 2 or 3 usually) or even the zinc, but I doubt that last. Do you get a nasty tasting “burp” that is “vitamin” tasting? If so, it’s very likely B1, 2 or 3.
In other words, go to a good vitamin store, and get a anti-oxidant pill, a multi-mineral pill and a B-complex. It’s not impossible you can get a free sample of each.
I am pretty certain it isn’t the anti-oxidants (Vit C, E, and a few others). But anyway, take one different each day, and see which makes you queasy. Usually, it’s best to take these with food, but not here, since you are testing.
Once you determine its (for example) one of the B-vitamins, then get a Niacin, B-6 and then B-12 individual supplement, and see if it’s any of those. Similar if it’s a mineral causing it.
Let’s say you find it’s B-1. Then, get an antioxidant sup, a Multi-mineral complex, Folic acid, then B-12, Niacin & B-6.
For women, here’s what you may want: Iron, B-12, B-6, Calcium & Magnesium, Folic Acid & Anti-oxidants. YMMV, depending on diet, age, smoking, and so forth. You may not need anything else, so why take it? Don’t take mega-doses, either.
Note that eating a balanced diet may well be better. You can also consult your personal MD.
