Your Patients and the Benefits of Amino Acids 

CHK stand for Clinical Health and Knowledge, reflecting our ongoing commitment to quality, scientific research, and the promotion of accurate information.

Amino Acid Nutrient Support

Amino acid nutrients can be used to naturally support many specific areas of normal brain, gut, and overall health.

  • Healthy, normal appetite 
  • Healthy, normal sleep 
  • Healthy, normal energy 
  • Healthy, normal memory and learning 
  • Healthy, normal movement and balance 
  • Healthy, normal motivation 
  • Healthy, normal focus 
  • Healthy, normal reward drive
  • Healthy, normal toxin maintenance

For more specific information about the areas of support, view the Health Benefits of Amino Acid Support area on the provider home page and click on each area. 

Your Patients Supported by Science

Numerous peer-reviewed research articles examine how amino acids can promote normal health in various ways.

Serotonin and the catecholamines regulate several key pathways in the body. Our formulations have been studied using many methods, including biomarkers to examine the correlation between amino acids and many areas of health and wellness. 

Our amino acid formulations:

  • Offer balanced support of serotonin and the catecholamines (dopamine, norepinephrine, and epinephrine). 
    • Serotonin is known to control mood, appetite, sleep, memory, learning, and temperature regulation * 
    • The catecholamines are known to control movement, balance, motivation, and the drive for reward *
  • Support the Central Nervous System (CNS) via vitamins and co-factors, which cross the blood brain barrier (BBB) 

*These areas of support represent healthy, normal support and not disease management. 

Using amino acid nutrients to support normal health is not a new practice. Many companies offer products that contain amino acid nutrients. CHK Nutrition’s formulas are different because they address a critical area of brain and neurotransmitter health that many formulas have overlooked – the need for balanced amino acid administration.

Improperly balanced amino acid nutrients may deplete serotonin and/or the catecholamines throughout the body. It is possible to do more harm than good by administering incorrectly balanced amino acid precursors. CHK Nutrition’s amino acid formulas support balanced amino acid administration.

Common Reasons Patients Request Our Balanced Amino Acid Nutrients

“My life is busy and I feel like I am stuck in a fog of to do lists. I don’t know what is worse, the exhaustion or periodically forgetting things. I would like to find a supplement that may help support focus.”

“Most nights I sleep reasonably well, but occasionally I end up with a couple nights of bad sleep, which leaves me feeling rundown for days. I would like to find a supplement that may help support sleep patterns.”

“I am not normally an angry person, but lately I have a shorter fuse. I feel frustrated and am struggling with patience. It doesn’t happen all the time, but I don’t want it to happen at all. I would like to find a supplement that may help support calmness.”

“I feel like there is a continual weight on my shoulders. My responsibilities leave me stressed and feeling like I am one step away from yelling, “the sky is falling.” I know that I don’t have to focus on everything. Sometimes I can prioritize and keep things in perspective, but other times it can be taxing. I would like to find a supplement that may help maintain a balanced perspective.”

“I can usually convince myself to eat well for three or four days, but by day four or five I find myself caving to bad choices. It feels like my willpower is taxed and I would really like to find a supplement that may help support a balanced appetite”.

Your Patients and Side Effects

Have a plan to help your patients

Amino acids have relatively few side effects. Side effects are generally mild and typically occur in a small percentage of the general population. The most common side effects are nausea, heartburn, gas and bloating. These can typically be reversed with proper nutrient management.

Most patients can take amino acid nutrients without any side effects. The best way to help your patients and to prevent them from permanently ending amino acid nutritional support is to educate them in advance that some patients experience side effects when starting amino acid nutrients.

Information on side effects can be found in Managing Side Effects and The D5 Dosing Guide, seen below:
