Premium natural ingredients with proven effects

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.

Guarana and Garcinia Cambogia

Guarana provides a sustained energy boost and stimulates fat metabolism, contributing to weightloss. Garcinia cambogia (Garcinia gummi-gutta) contains hydroxycitric acid (HCA), a natural compound that inhibits the enzyme lipase, which is responsible for fat breakdown in the body. This helps in preventing fat accumulation and weight loss in the body.

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.

Gymnema sylvestre extract

Gymnema sylvestre (Gymnema sylvestre) is a plant used in Ayurveda, a form of ancient holistic medicine practised in India. The Hindu term for it is gurmar, roughly translated as 'sugar destroyer'. This is because gymnema leaves contain a compound called gymnemic acid, which selectively inhibits sweet tastes, resulting in a reduced desire for sweet.

Kelp

Kelp (Ascophyllum nodosum) is a large seagrass that grows in nutrient-rich underwater habitats in shallow oceans. It is a source of iodine, which plays a role in the production of thyroid hormones and the normal functioning of the thyroid gland. Iodine also plays a role in cognitive function and contributes to the functioning of the nervous system.

Zinc

Zinc contributes to normal immune function, contributes to normal DNA synthesis and cell division, helps protect cells from oxidative damage, helps maintain normal bones and contributes to normal cognitive function.
