I remember taking Dexatrim capsules years ago high school. So when I was looking for something to kick start my diet, I remembered it had worked in the past so I was hopeful it would work again. I really felt the need to boost my metabolism and to get serious about my diet because I felt very flabby after my child was born. I felt this was a good option because I trusted the company brand as it has a long standing reputation. Unfortunately it didn't work for me. Dexatrim Max left me with a jittery shaky feeling and did not help result in weight loss. It caused my heart rate to unnaturally speed up and my legs physically felt week. It did not curb my appetite but it did not increase it either. I stopped using it after 2 weeks and decided it wasn't going to work for me. I had high hopes being that I used it in the past with decent results, this time around was not successful. Effectiveness It did not work for me and I only took it for a short time due to feeling ill after taking it. I suppose it may work for someone who doesn't have a reaction to it. My co-worker didn't have any side effects and had better success. Everyone is different and reacts to supplements differently. It is not expensive so I would suggest someone give it a try before using one of the other much more expensive supplements. Plus it is available in drug stores and mass retailers. Side Effects Dexatrim left me feeling jittery and shaky. I had increased heart rate and leg weakness. It was not safe for me to continue using especially because I am a full time mom to an infant. Dexatrim Max and I had a very short lived relationship though it has worked for other people.
