Made from scientifically proven active ingredients
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 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 contributes to the normal synthesis of catecholamines, including adrenaline, noradrenaline and dopamine.
Vitamin C is an important antioxidant that protects our cells from oxidative stress. It is necessary for the normal functioning of bones, teeth, cartilage, gums, skin and blood vessels.
