Can tuna be substituted for amino acid supplements?

Sep 27, 2008 by Jacob J | Posted in Diet & Fitness

Silly question I know, but amino acid supplements are basically protein right? I was curious because people take amino acid supplements before they do their cardio. So could tuna be substituted as an amino acid supplement since it has almost no carbs or fats and lots of protein?

Yes, protein is simply made of amino acids, so tuna would work similarly. The main advantages of aminos are that they are digested quickly and some specific aminos can have almost drug-like effects.

It's one of those small issues though. The main thing is to follow a great training and nutrition plan. If you need a good plan I would recommend this one: http://www.athleticmusclebuilding.com

It worked well for me.

Tired of taking supplements- brewers yeast in place of taking an amino acid supplement?

Nov 12, 2009 by rissa | Posted in Alternative Medicine

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)

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!

Glutamine: A Good Supplement for Bodybuilding? | ABC article directory

Since glutamine is a non-basic amino acid, even though it makes up about 65 percent of amino acids in the thickness, the assembly can dream up it out of other amino acids and molecules in times of loss. During emphasis, our amino acids are diminished, which limits muscle extension. So, it makes quick-wittedness to use glutamine as a appurtenance for bodybuilding for some people. However, prevalent scrutiny does not show that glutamine is an requisite addendum for bodybuilding. Some engrossing findings of the examination are that while glutamine does travail under clinical weight testing, it doesn't do anything to boost a workout; quantities of glutamine that would charge an ordinary bodybuilder anywhere up to $1000 a year were hand-me-down for this trial.
