Three complexes to be taken at key times of the day following chrono-nutrition principles
Weight Loss - Complex 1
Targets belly and hip fat
To be taken upon waking, our Complex 1 incorporates a patented ingredient derived from gynostemma pentaphyllum for fat loss.
Its technology makes it 10 times more powerful than traditional gynostemma pentaphyllum extracts. The key mechanism is the activation of AMP-activated protein kinase (AMPK). Activation of the AMPK pathway supports body fat reduction by promoting fat oxidation while decreasing fat synthesis.
It also combines Acetyl-L-carnitine and Cola Nitida to help the body transform fats into energy, promote slimming, and contribute to body weight control. The complex also includes certain vitamins important for healthy metabolism and maintaining normal digestion (including vitamins C, B1, B2, B3, B5, B6, D3).
