Made from quality ingredients

ID-alG™

1. ID-alG™

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

L-carnitine

2. L-carnitine

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

L-tyrosine

3. L-tyrosine

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

Vitamin C

4. Vitamin C

Vitamin C helps protect cells from oxidative stress, supports the nervous and immune systems, and helps reduce tiredness and fatigue. Vitamin C also contributes to normal collagen formation.
