I started with FitLine Optimal-Set and I couldn't believe what it was coming up with. I am much more energetic, I do not need naps anymore. Before using Fitline, the muscles were sore for a long time and were cramps and veins often. I love these products that make me feel more balanced and more vibrant! My stomach is also working normally now and my skin has experienced a significant change! Now, I have used these already for 8 years and I recommend them to everyone!
