I have been using Isotonic for my workouts for a few weeks now and I have to say I am really impressed with the results. It keeps me hydrated throughout my workout and I don't feel tired or fatigued like I used to. I also love the added vitamins and minerals that help support my immune system. Overall, great product!
As someone who plays sports regularly, I need to make sure I am properly hydrated and my electrolytes are in balance. Isotonic has been a game changer for me. It keeps me energized and helps me recover faster after an intense game. I also love the added L-carnitine which helps with muscle function.
I recently started a new job which requires a lot of physical activity and I was struggling to keep up with the demands of the job. Isotonic has been a lifesaver for me. It keeps me hydrated and provides the energy I need to get through the day. I also love that it has added vitamins and minerals that contribute to normal psychological functions. I feel more focused and alert throughout the day.
Made from quality ingredients
L-carnitine is an amino-acid derivative that plays a key role in fat metabolism in the body. It is a natural compound produced by the body and can also be obtained from certain foods and dietary supplements.
Vitamin C helps protect cells from oxidative stress, supports the nervous and immune systems, and helps reduce tiredness and fatigue. Vitamin C also contributes to normal collagen formation.
Magnesium contributes to the normal functioning of the nervous system and muscles, normal energy-yielding metabolism, and also supports electrolyte balance.
Calcium is an essential mineral that supports muscle function, the normal function of digestive enzymes, and is necessary for maintaining healthy bones and teeth.
B-complex is a group of vitamins—B1, B2, B6, B12, folic acid, pantothenic acid, and niacin—that are important for our nervous system. In addition to their shared function, each B vitamin has other important roles in the body.
