I'm a herbalist and have always taken nutrients. However, for more than 30 years, since having my son, my lower legs and ankles swell terribly when I sit for long periods. They call this edema in the medical world. The last fee years, my feet and legs would swell to the point that I couldn't get my shoes on if I took them off for relieve of the pressure. No doctor in 30+ years and has cured me of this. I read up about amino acids and decided to Start taking them. This dosage is waaay more than needed daily, so I take very little. However, within 3 days the Adema was gone and I have no more swelling in my legs and feet when I sit for long periods. This leads me to believe that I was lacking in these nutrients, and the edema was the symptom warning me something was wrong. Not once in 30 years did doctors tell me that edema could be caused by an amino acid deficiency. I am angry that doctors are happy to drug you up to hide symptoms, but don't bother to heal the underlying ailment. Ive been taking very small doses of this product for more than a month and the edema has never returned. If you have edema, try these amino and maybe, just maybe, an amino deficiency is what is causing your symptoms as well. Also. I won't confirm just yet, but my memory and sleep has been improving since taking this as well. I've seen about a 15% improvement in my memory, and this past week, I've been sleeping better and waking up before my alarms. I suffer from acute insomnia, so this is a huge result. I'll see if my memory and sleep continue to improve with use and update in a few months.
