Since so little formal empirical research has been done on Atkins, and since there SO many ways of "doing Atkins," ranging from high to low nutritional benefit, I tend to use more supplements than others may choose to use. I especially tend to watch electrolytes (calcium, magnesium, potassium) carefully, as mineral depletion seems to make my workouts hard.

I take extra calcium (100 mg), magnesium (200 mg), potassium (200 mg), chromium picolinate (200 mg), vitamin C (1000 mg), vitamin E (400 IU), flaxseed oil, fish oil, L-carnitine, Coenzyme Q-10, and a multivitamin. I realize this sounds like a lot, and it is, but I figure the only thing I KNOW I'm always getting is protein and beta carotene (from all my dark green leafy veggies, broccoli, etc.).

I am sure that others do just fine with little or no supplementation, but since I'm still pretty new to this WOE, I prefer to start out being sure I have what I need, then taper to the bare essentials later.
