Dear Howard:
The best chromium supplements that doesn't cause "jumpy" conditions is the chromium chloride. The chromium picolinate people complain to me about jumpiness, by the way. Therefore for the time being, I prefer to use chromium chloride as it caused the least problem. The second choice I used is likely to be chromium polynicotinate, because it's a vitamin B from of chromium. Picolinate might have been well documented, but this is also a problem since the patent holder also financed the research trials, without comparisons to the other forms of chromium. Therefore, I prefer to use the ones with the least problems. In my experience, if they do have problems the side effects can bet bad in a few cases, and hence it's best to stick to the ones without any problems from general use.
In any event, magnesium supplements will be the primary remedy when we have to discuss with heart muscles, and heart beats, it helps muscles become more relax, while calcium makes them too contractive.
