Yes, I believe that whole food sources of nutrients are ideal, but when dealing with AF the body is not in an ideal state and has lost significant internal balance, necessitating "pharmacological" doses of nutrients from what I understand.
I think a good analogy would be if I caught the common cold, then I would probably treat it with whole food vitamin C, rest and plenty of fluids. But if I came down the flesh eating bacteria, I'm going on heavy dose Antibiotics and I.V. vitamin C ASAP.
