If you're searching for reliable advice about food supplements, you're in the right place. Here's what the AHA recommends:

The American Heart Association recommends that healthy persons obtain adequate nutrient intakes from foods eaten in variety and moderation, rather than from supplements. The Recommended Dietary Allowances (RDA's), published by the National Research Council, represent the best currently available estimates of safe and adequate dietary intakes.

What's more, all nutrients are potentially toxic when ingested in large enough amounts over prolonged periods. For otherwise healthy people, there are only limited data suggesting advantages for taking certain vitamin or mineral supplements in excess of the RDA's. These data are insufficient for any recommendation from the AHA.
