Years ago I had Hyperthyroidism that caused me to lose all of my muscle and had me within 5 months to live before inevitable organ failure. I had RAI (Radioactive Iodine) treatment and, though I regained my weight and muscle, it had no strength and I was in constant pain. I was diagnosed with Hypothyroidism and muscle degeneration, I feared being on pain pills for the rest of my life and was always on the lookout for anything that could help.I decided to try this supplement and it's been a godsend! In the first week of using it I had a 50% reduction of my pain and 50% energy increase. Now, I'm not a doctor and can't claim this will work for everyone in my situation but I can say that, for me, it's performed worlds beyond my expectations!When you've tried everything else, what have you got to lose?This gives me more energy and helps me get through the day, especially on those days I am working out. So far I am impressed.I like everything about the pills easy to swallow. I take them after workout . BCAA is great for your body. . Thank you , Tamara CloerI am getting up in age and as such am losing muscle tone. I have begun doing moderate workouts without results. A friend suggested taking Natures Craft branched chain amino acids which are supposed to help support healthy muscles. I have been taking them for a few months now and have noticed a pretty nice improvement in my muscle tone! I would suggest Natures Craft branched chain amino acids.I like to take this product before a gym workout or for a full active day as it helps my body feel better!Good choice! I've just finished my second bottle. I purchased this because I'm a nurse and the long shifts are hard on my body physically, as well as I'll sometimes go 12+ hours with no meal. These have helped support my muscle maintenance and literally feed my muscle tissues what they desperately need and lack many days. I've had no side effects what so ever and they're completely tasteless. Not only have I maintained tone and strength, but its improved and my body doesnt ache so badly after hard shifts and long days.Being older, I wanted to try something that would held keep muscle mass along with reducing soreness and fatigue. After a month I feel that I have gained muscle and haven't been sore at all. I use amino acids for my horse to build muscle, so why not me!!
