It ultimately has control over all your bodily functions. The brain is a very vulnerable organ and is affected instantaneously by nutritional deficits and imbalances. These problems can manifest themselves in numerous cognitive disturbances, including short-term memory loss. Fortunately, the brain is also very responsive to nutritional optimization and supplementation and lifestyle upgrades. Buy from publishers who have a background in natural health.
Traditional publishers are often clueless about nutritional approaches to human well-being.
They only understand image advertising and best-selling sales. That's what I've been doing to earn my living since 1993. Do NOT buy packages that promise or imply they'll cure what ails you virtually overnight or make you healthy as a horse in a matter of weeks. Claims like these are obviously bogus. If the publisher won't stand by his products with an ironclad guarantee, you know he's not entirely on the up and up.
