Ask HN: Which vitamin supplements do you take?

I would be interested in knowing what vitamin supplements you all take and why (Include the brand name).

I currently take: - Centrum multivitamin - Now foods vitamin D3 (2000IU)

I also just bought the Now foods omega 3 supplement. It smells rancid. I'm probably going to throw it away. Does anyone know of a good, purified brand? (Preferrably something that uses d-gamma and d-delta forms of vitamin E to prevent oxidation/rancidity)

Why do you take vitamin supplements?

I don't take them and would only do so if I had some reason to think I was deficient in them and then only the the particular vitamins in which I was deficient.

instead of extra vitamins, I just eat less carbs. Same effect ;)

Kirkland's fish oil/omega-3 (this one is good enough for me, no issues)

Now/Carlsson's vit D3 (2000IU)

LEF's magnesium, taurine and super-k (vit. k1 + k2)

GNC's creatine monohydrate

I take these on and off or cyclically (some are bad combinations). I'm thinking of getting a multivitamin, but most of them have their own shortcomings.

Dear naysayers: It's straightforward enough to take supplements at breakfast and then build on that with later meals. And it's actually quite a lot of fun to experiment with something fundamental to well-being.

I currently take a multivitamin, Omega 3, 600mg calcium + 400 IU Vit D, plus 6000IU of D separately, and variable amounts of whey protein. The multi is an all-arounder, the Omega 3 is for perceived brain power benefits. I go for a lot of Vit D because it's just been amazing for mood, confidence, general well-being, and I started with the calcium to complement it. The whey protein is used to keep me on the straight-and-narrow with the rest of my diet, by controlling hunger in a form which offers few obvious downsides.

As far as brands go, I typically get supplements either from Trader Joe's or from CVS. I don't really pay much attention to which ones I'm using as I haven't seen a quality difference yet. I've been going through some Omega 3 from Trader Joe's for ages, no problems with it. For the whey I'm currently using "Designer Whey." I don't know if I'll stick with it; every protein brand seems way different.
