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.

Narejeno iz znanstveno dokazanih učinkovin

L-Carnitine

L-Carnitine

L-carnitine is an amino acid that is crucial for fat metabolism because it ensures that long-chain fatty acids are transported to the mitochondria where they are converted into energy.

Vitamin C

Vitamin C

Vitamin C contributes to the protection of cells from oxidative stress and is also essential for the formation of collagen.

Magnesium

Magnesium

Magnesium plays a key role in maintaining the normal functioning of the nervous system and muscles and supports energy metabolism and electrolyte balance. With magnesium citrate, the form that allows the best absorption and bioavailability, you can replace lost magnesium and avoid deficiencies that can manifest as unpleasant fatigue, lack of energy and muscle dysfunction, especially as frequent muscle cramps.

Calcium

Calcium

Calcium is an essential mineral that plays a crucial role in maintaining strong bones and teeth. Calcium citrate, a natural form of calcium, can help replenish calcium levels in the body. A deficiency in calcium can lead to weakened bones and teeth.

B-complex

B-complex

The B complex is a group of vitamins B1, B2, B6, B12, folic acid, pantothenic acid and niacin, which are important for our nervous system. In addition to their common function, each of the B vitamins has other important roles in our bodies. Vitamins B1 -5 and B12 work against fatigue and exhaustion. Folic acid is important for the normal functioning of the immune system. Vitamin B2 is important for the absorption and metabolism of iron and also acts as an antioxidant, protecting our cells from oxidative stress.
