I love niacin.

There is nothing better to detox heavy metals and it gives the energy patient of heavy metal poisoning don't have.

Now understand that put aside the detox of mercury and lead which have Cilantro/Chlorella and EDTA respectively to chelate them. For EVERY other heavy metals ( Aluminum, Strontium, Arsenic, Barium, ...) it's a great chelator, like all amino acids are.... except this one gives energy on top of chelating. I wouldn't stick to 1 amino acid only to detox.... I would make a cocktail, the more amino acids the better, so you might as well diversify, after all amino acids, are essential components to our life on this planet.
