Made from quality ingredients
KSM-66 is one of the highest concentration, full-spectrum ashwagandha root extract on the market today, standardized to >5% withanolides by HPLC.
Panax ginseng is a traditional adaptogenic root extract with a light beige to brown color, a characteristic herbal aroma, and a mildly bitter taste. It is known for its numerous benefits, including helping to maintain good cognitive performance and physical and mental capacities in cases of weakness, exhaustion, tiredness, and loss of concentration.
The B complex is a group of vitamins B1, B2, B6, B12, folic acid, pantothenic acid and niacin, which are important for our nervous system. In addition to their common function, each of the B vitamins has other important roles in our bodies.
Chamomile extract is a plant extract derived from chamomile flowers. Chamomile supports digestion and helps with indigestion and flatulence.
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.
L-carnitine is an amino acid derivative. It is a natural compound that is produced by the body itself or can be obtained from certain foods and food supplements.
L-Tyrosine is a non-essential amino acid that occurs naturally in the human body and in a variety of protein-containing foods. It is a building block used by the body in several biological processes and is a precursor to various naturally occurring compounds.
Vitamin C plays a role in the protection of cells from oxidative stress. It contributes to the functioning of the nervous system, has a role in the functioning of the immune system and contributes to the reduction of tiredness and fatigue . Vitamin C also contributes to normal collagen formation.
