I've just finished off my first 6 weeks of using GABA & wanted to write a review. First of all, I suffer from sometimes mild to severe anxiety & mild depression. Herbs have always been my first choice against medications because of less side effects and some herbs are safer than chemicals.I was using an anxiety formula but wanted to narrow it down to just one herb to see if it would work as good, so after some research I decided to try GABA. I wanted to try GABA because it is safe, has no side effects and is supposed to calm nerves, be a relaxant and help with sleep. The whole month I took one pill in the morning and one pill at bedtime. It worked right away for me and i noticed less anxiety, with an easier time falling asleep at night. Now that I have been using it for several weeks i think that one pill per time might not be as strong, so i am going up to 2 pills during the day and one at night to see if that helps some. Over all this has helped me feel less anxious and i am hoping that 2 pills in the morning will take the tension off on stressful days. These pills are quite big but not hard to swallow and do not have an awful taste like Valerian root does. Inside the pills is powder, which my doctor says is better to take because they digest better in the body. I wouldn't say these are strong as prescription medications are but for an herb they do work well.
