Amino Acid Supplements

Question: Tired of taking supplements- brewers yeast in place of taking an amino acid supplement? is brewers yeast almost a complete source of amino acids if i took the rec. dose of 4 TBS a day? (its so much cheaper than amino acid supplement and has b vitamins and other minerals)

Answer: Well, that's a tough yes/no answer. You're right that it's a good protein source that has a good variety of Amino Acids and other nutrients... but the other nutrients might cause you problems. A typical Brewer's Yeast has about 8 grams of protein per tablespoon... but it also has almost 100 mcg of Chromium in that same tablespoon. In order to get the RDA of 50 grams of protein, it would be about 6 tablespoons of Brewer's Yeast... which would be about 600 mcg of Chromium. The reason that could be a problem is that the RDA of Chromium is 120 mcg and is normally recommended up to 200 mcg per day... but more importantly, Chromium may enhance insulin sensitivity, which can affect glucose levels. Needless to say, that can be potentially harmful (or potentially helpful depending on the dosage and needs) for diabetics or hypoglycemics, but it can also throw off blood sugar levels for those who aren't in higher doses like that. Before taking that much Brewer's Yeast, I would check with a doctor that knows about nutrition to see if it would be safe. If you would like a safer alternative, you could also take a whey protein powder (or pea or similar non-milk protein if you can't handle the dairy) to get most all of the essential Amino Acids. Good luck and I hope I helped!
