What is Brain Complex?

Brain Complex is a premium natural supplement designed to help with mental performance, focus and motivation. You can’t take care of your body if you don’t take care of your mind first, so WeightWorld created the Brain Complex as a natural way to give yourself a kick start. Consisting of a one of a kind blend of carefully chosen vitamins, amino acids and natural ingredients, this formula is designed to support brain function and help men and women have the mental energy and motivation they need to stick to their health goals.

Weight loss and motivation

What are the key factors that can help us with our weight in the long term? Of course, diet and exercise are the actions to weight loss, but behind them you need energy, self-control, motivation and focus in order to stay on track. According to research from the Personality and Social Psychology Review, these do not come as an unlimited supply and there needs to be a source. Generally, this is found in glucose and sugar, but it’s not going to be that healthy. For those of us avoiding sugar, it can mean we need a natural way to help recharge our batteries and give us the mental energy we need.

Brain Complex ingredients

In their exact quantities, each of the 17 active ingredients that make up this natural formula have all been carefully combined and selected due to a variety of potential benefits, including in promoting mental focus, energy and motivation. The key active ingredients that make up this exclusive includes:


Vitamin Blend
Within the formula are a number of brain vitamins including B1, B2, B3 and C. These are known to contribute to normal psychological function, to the reduction of tiredness and fatigue and to the protection of cells from oxidative stress.


Amino Acids
This mental-performance formula is full of beneficial amino acids, including L-Taurine, L-Theanine, L-Tyrosine and L-Phenylalanine. These are often used as a natural way to support mental performance and physical activity.
