Made from scientifically proven active ingredients
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. Vitamins B1 -5 and B12 work against fatigue and exhaustion. Folic acid is important for the normal functioning of the immune system. Vitamin B2 is important for the absorption and metabolism of iron and also acts as an antioxidant, protecting our cells from oxidative stress.
The orange flavour adds freshness and a great taste to the drink. No added sugar.
Serenzo™ is a natural, organic active ingredient derived from the extract of the orange tree. Serenzo™ (acacia gum, sweet orange extract) has been shown to regulate stress and inhibit the action of the D2 receptor, which is responsible for the body's stress response.
