Every moment of every day,
a complex balancing act is taking place in your body.

Complex metabolic processes break down the foods you eat into component chemicals and elements. Your circulatory system shuttles these raw materials around the body to where they're needed. Your brain consumes about 20% of your body's energy, and is greedy for the nutrients required to synthesize neurochemicals. Learn more about your brain.

When the brain doesn't get the nutrients it needs, cognitive capabilities are diminished. Remember – the brain is the center of all your senses, all your thoughts and memories. Any or all of the brain's functions can be disrupted by inadequate nutrition.


L-glutamine, often simply referred to as "glutamine" for short, is one of the most important amino acids for your body. It's so important that, at any given point in time, 60% of the amino acids in your body are glutamine (or some variation thereof). Glutamine is important for the health of your intestines, your immune system, your muscles, and - most importantly - your brain.

Although glutamine is important for brain and body health, it is not what scientists would call "essential". An essential amino acid is one that you have to get from either your diet or a dietary supplement. Glutamine, on the other hand, is synthesized in your muscles. But just because your body can make more of it on its own doesn't mean that it will. You have to give it the right nutrients if you want to get all the benefits that glutamine has to offer.

Glutamine Benefits

One of the main reasons glutamine is an important part of Constant Focus is because of its profoundly healthful impact on your brain. When your brain has a good supply of glutamine in it, it converts it into two different substances: glutamic acid, and GABA. Gaba is important for reducing anxiety and maintaining a healthy emotional balance. It's so effective that some doctors even recommend it to patients that are having problems taking common anxiety medications or for people with sexual dysfunctions related to anxiety. It can also help some relax better at night and experience a healthier sleep cycle - which is one of the best things you can do for optimal brain health!

Then there's glutamic acid. This is a form of glutamine that is rapidly synthesized and uptaken by the brain whenever the body doesn't have enough glucose to power your normal brain functions. It's said to have a more profound effect on enhancing neurological function than other stimulants like sugar or caffeine. Best of all, it doesn't come with the "sugar crash" you would get once those other stimulants are depleted from your body.

One of the most important things glutamine does for your body is to correct any toxic ammonia imbalances in your system. And, yes, the brain can collect a toxic amount of ammonia in it if you aren't careful. When this happens, it can lead to rapid brain cell aging and impaired cognitive function. It can even lead to neurodegenerative diseases if left unaddressed for too long. But supplementing with healthy amounts of glutamine can protect your brain cells from free radical damage and ammonia toxicity.

Glutamine Studies

You shouldn't just take our word for it on the health benefits of glutamine. Look at the science behind it. All the way back in 1995, a study published in the American Journal of Clinical Nutrition discovered that even as little as 2g of glutamine was enough to significantly boost both glutamine and HGF levels in the brain. This is important for two reasons. Number one, more glutamine in general provides more energy for your brain, which helps enhance cognitive function. Two, higher HGF levels triggers higher levels of BDNF, or brain-derived neurotrophic factor. This hormone is essential for helping your brain heal damaged brain cells and grow new ones. It's also an essential part of long term memory maintenance.

A more recent study from 2003 did a similar experiment on an even larger group of middle-aged/elderly subjects. It was published in the journal of Nutritional Neuroscience, and it was a double-blind, placebo-controlled study, so you can rest assured the methodology was sound. Glutamine supplements combined with Niacin (which is another ingredient in Constant Focus) showed a 70% improvement in cognitive function thanks to a triggered boost of IGF-1. And it accomplished this task in as little as three weeks.

These obviously aren't the only studies on glutamine and its cognitive enhancement properties. But they are the most well-known and definitive ones performed on humans. There are dozens more performed on lab rats and other animals whose brains perform similarly to that of humans. And they all pretty much say the same thing: that glutamine is great for your brain.

So Is Glutamine Good for Brain Optimization?

As you can clearly see, glutamine is crucial for brain health and optimization. It helps keep your nitrogen levels balanced so that you flush more toxins out of your brain cells. It's also great for the overall healthy function of your nervous system. And if you don't get enough glutamine on a regular basis, the health of your gut - and the gut-brain axis that keeps you physically as well as mentally healthy - would be severely compromised. So do yourself a favor and give yourself the gift of glutamine by purchasing your own supply of Constant Focus today.
