The results are quickly noticeable and the weight loss is more successful than if I had only exercised and eaten healthily. I sleep much better and notice a change around my waist!

After about a week of use, I already have significantly less food cravings, and I also noticed that some fat has been lost, especially in the stomach area. Great!

L-Carnitine

1. L-Carnitine

L-carnitine is an amino acid derivative that plays a key role in the body’s metabolism of fat. It is a natural compound that is produced by the body itself or can be obtained from certain foods and food supplements.

Coffee & Guarana Extract

Elderberry helps to supports the immune system, helps in weight control and helps to lose weight in addition to dietetic measures.

ID-alG™

4. ID-alG™

ID-alG ™ is a grape seed extract and an extract of the brown seaweed Ascophyllum nodosum, which is rich in long-chain polyphenols called phlorotannins. Ascophyllum nodosum reduces fat absorption and helps eliminate fat deposits, which consequently affects body weight.
