Premium natural ingredients with proven effects

Nettle leaf extract

Nettle is one of the most well-known medicinal plants and is excellent in stimulating the excretory functions and removing water from the body. It also supports the excretory functions of the kidneys, venous circulation and contributes to the functionality of the urinary tract.

Elderberry Extract

Elderberry supports sweating and contributes to weight loss and weight management. It also supports the immune system and improves blood circulation.

ID-alG™

ID-alG™ is an extract of the brown seaweed Ascophyllum nodosum, which is rich in long-chain polyphenols called phlorotannins. They help to inhibit the action of the two main digestive enzymes, lipase and amylase, and block up to 77%* of carbohydrate digestion and 63%* of fat digestion.

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.

L-Tyrosine

L-Tyrosine contributes to the normal synthesis of catecholamines, including adrenaline, noradrenaline and dopamine.

Asparagus extract

The hemlock tree (Polygonum aviculare) is a type of plant found all over the world. It helps in the excretion of water and the elimination of bacteria through the urinary tract.
