Abstract
The present invention relates to metal carboxylates and more particularly to chromium(III) and manganese(II) salts of short chain fatty acids. A method of making the same such that there are only sub part per billion amounts of these metals in other valent forms present in the resultant salts, and the salts are suitable for use as nutritional supplementation of living organisms with the organic metal salts.
Claims2
A food composition for selectively supplementing essential trace metals in a diet comprising:
- a food composition including a Cr.sup.+3 salt of a carboxylic acid, and low levels of Cr.sup.+6 ;
- and,
- said low levels of Cr.sup.+6 in said food composition having the equivalent of less than 8.3 parts per billion of Cr.sup.+6 per 8% total chromium in the food composition.
