Why iQ Brew Works

synergistic

/sɪnəˈdʒɪstɪk/
adjective
1. relating to the interaction or cooperation of two or more organizations,   substances, or other agents to produce a combined effect greater than the sum of their separate effects.

iQ Brew works by combining ingredients that work in synergy as opposed to being stacked. A lot of supplements these days fill their products with small doses  of individual ingredients just so they can claim the benefits, when in fact, the dosage in their product is so small you would require multiple servings a day just reach the minimum effective dose of the ingredient and potentially get the benefits (multiple servings more than likely means being spread out over the course of the day, before and after meals and affecting the bioavailability of some of the ingredients)

By choosing ingredients that work synergistically AND by using them in clinical dosage amounts, we're ensuring that when you look at the studies on our ingredients, you can bet that you will experience similar results due to not only the effective dosage being represented in each serving, but the combined effect yielding a greater outcome.

So what in iQ Brew is Synergistic and how?

CAFFEINE AND L-THEANINE

The calming effects of L-Theanine are greater than caffeines ability to stimulate, this means that when combined with coffee, it allows you to be alert and stimulated, but without the risk of being so stimulated you become distracted, jittery or anxious. In studies it has been shown to blunt caffeines "spike" in alertness and sustain it over a period of time, keeping you level headed and focused for a greater period of time.

Huperzine A and Alpha GPC

Essentially, your brains ability is limited by the amount of acetylcholine (The learning Neurotransmitter) it produces, knowing this, the body also produces and enzyme called acetylcholinesterase, this enzyme breaks down acetylcholine. 
Huperzine A works by preventing the breakdown of Acetylcholine by this method.
Whilst Alpha GPC is a precursor to acetylcholine, meaning that while Alpha gives you the building blocks to create more acetylcholine, Huperzine prevents the increased number of neurotransmitters from being broken down.
