Courses of Martin Jelínek are great complex and self-contained manual that helped me orientate myself in the branch of human nutrition, his health and supplementation issue. Because of time reasons, I chose online version of the course, so I could adjust the study according to my time schedule. Individual topics are synoptically, simply and readably processed and I liked them. I also appreciated system of mind maps. Thanks to them, lessons were well arranged and it was easier to remember them. It also supported my creativity. If you are interested in healthy nutrition and lifestyle, this course is definitely right choice.
