I was briefly a patient of Dr. Atkins a while back, and his core recommendations were:

Atkins Basic 3
Atkins Essential Oils
CoQ10
Carnitine

From there he would add based on other problems such as joint pain, high blood pressure, etc... but these recommendations were individiualized. If cost is an issue (when isn't it? ), you may want to just add some essential oils to your multi. You could take his Essential Oils supplement, but I like a product called Coromega. If your multi doesn't have about 200 mcg of Chromium picolinate, you may want to add that (and that one is cheap ). CoQ10 is great for heart health, but it can get pricey, as does Carnitine. For what it is worth (notta), I take:

Life Extension Mix Caps
Life Extension CoQ10
Coromega
Life Extension Alpha Lipoic Acid
