This is not a miracle pill. Supplements are, like the name suggests just supplements. That said, Spirulina is not something you absolutely need to have in your daily diet. It is however something good to have. I have made changes to my daily such as changing my diet, leading a more active lifestyle and finally, introducing supplements into my diet. I must say I am feeling rejuvenated. No longer am I that tired. This could be due to my weight-loss, my strengthened body, the supplements or all 3. I am more convinced that all this goodness is due to all 3 changes working synergistically. Grab a bottle now and try it. I took a leap and faith with the 720 capsules bottle and never looked back. You can always go for the smaller quantities on your first try. Good luck with the results!!!
