Beyond Aminos for Performance, Anti-anxiety meds, and All the Essentials
FOOD for thought:
Branched-Chain Amino Acids only account for roughly 35% of the essential amino acids in our muscles. That leaves 65%…. BCAAs are out. Vegans trying to gain muscle or “vegan athletes” could consider supplementing LEUCINE specifically due to MANY vegans lacking proper leucine levels for muscle growth but we see no reason to load up on BCAAs without other essentials. BCAAs are cheaper than EAAs (duh). There is an abundance of marketing claims behind BCAAs (but they are so 2005). We recommend eating real food sources of protein and supplement with EAAs for specific application.
Specific applications may include:
Brain health (sleep, mood, anxiety)
Muscle Preservation (growth and maintenance)
Nursing (yes, that is correct…)
… and many others.
How we formulated KTX Nutrition’s Essential Amino product:
1.) There is a very specific ratio needed of essential amino acids to make protein. The balance study is done on nitrogen utilization.
2.) We removed L-histidine. Arguably an essential amino acid, L-histidine can be formed by the body with the proper ratios of the 8 essentials and has been proven to decrease the efficacy of the other EAAs from 99% to 94% when consumed in addition to Arginine. Every % counts.
3.) We use 100% L-Form aminos. Any aminos not “L-Form” are essentially useless and a waste of money. Many supplements will claim high numbers of amino acids but really they are just loaded with “fillers” like “r-form” or those no listing any “L-” before the amino type.
4.) Our aminos will not cause a blood glucose spike, insulin sensitivity, and are not “cheap quality” like BCAAs. The essentials contain branched chain aminos L-Leucine, L-Isoleucine, and L-Valine however these BCAAs are not “superdosed” like many other products and they are in proper nutrition balance.
EAAs compared to FOOD:
Products like “whey protein” may only convert 15-20% of the protein by weight into useable Aminos. This means 100 grams of whey protein consumed would compare to taking 20 grams of essential amino acids, but will also likely add some undesirable gastric effects, unfavorable uric acid levels, as well as inflammatory issues at this amount.
Similar to Aminos in the form of BCAAs (branched chain amino acids), up to 70% of a beef steak can be converted into carbohydrate once consumed. Over consumption of these proteins will spike blood glucose, create insulin sensitivity, and are not ideal protein forms. This is one of the main reasons many people who eat excess flesh meat protein without a balanced diet have metabolic health concerns.
Lastly, egg whites are still trending (we don’t know why). Approximately 16% of the protein consumed from egg whites is effectively utilized into body protein. This is a horrible conversation rate and the egg white lacks the nutrients and supportive aminos that come along with the yolk. This is mainly in part to the majority of the methionine existing in the yolk, which increases the efficacy of the protein retention from the WHOLE EGG. We encourage whole egg or no egg at all. (+ they should be free range eggs).
SO What Are Amino Acids?
Amino acids are the building blocks of protein and serve as the catalyst for nearly every chemical process in the body. Most people associate amino acids purely with protein synthesis and muscle gain, but they’re also necessary for nearly every other physiological function, including enzyme production, hormone regulation, cognitive ability, neurotransmitter balance, and metabolism. There are 20 amino acids in total, and all of them are required to make these vital processes happen.
What Are the Essential Amino Acids (EAAs)?
Of the 20 amino acids, nine are classified as essential. Essential amino acids are the ones that the body can’t produce itself; they must be acquired through diet, specifically from protein-rich foods like meat, fish, and eggs, and of course, amino acid supplements. EAAs support the body in several critical ways:
Lysine plays a role in growth hormone secretion, which supports muscle repair and recovery. It’s also a critical component of structural proteins like collagen and elastin, which are important for building strong connective tissue.
Methionine helps the body process and eliminate fat, promotes cardiovascular health, and supports liver function to help the body eliminate toxins.
Phenylalanine has a pain-killing and antidepressant effect and is necessary for the synthesis of norepinephrine and dopamine. It also stimulates the release of adrenaline and noradrenaline, which are critical for nervous system function.
Threonine supports fat metabolism and immune function. Like lysine, it’s also a crucial component of structural proteins and connective tissue.
Tryptophan is a precursor for serotonin, which regulates sleep, appetite, and mood. It also has pain-suppressing qualities and can increase pain tolerance during hard workouts or competitions.
Leucine is critical for protein synthesis, blood sugar regulation, and growth hormone production.
Isoleucine helps prevent muscle from breaking down during exercise, which could lead to faster recovery. It’s also important for immune function, hemoglobin production, and energy regulation.
Valine helps stimulate muscle regeneration and is involved in energy production.
Histidine is a precursor to histamine. Histidine’s status as “essential” is debatable since it can be easily produced in the presence of the other essential amino acids. This is why histidine did not make the cut in our “essentials blend.”
What Are the Branched Chain Amino Acids (BCAAs)?
Three of the essential amino acids – leucine, isoleucine, and valine – are known as the branched-chain amino acids (BCAAs), named for their branched chemical structure.
The BCAAs are unique because they are metabolized in the muscle instead of the liver. This means that they’re available in the bloodstream soon after ingestion and can be used for quick energy during exercise. BCAA supplements are popular among athletes because they’ve been linked with increased muscle mass, decreased fatigue, and improved glycogen storage.
However, the supposed benefits of BCAAs are often embellished, misunderstood, and some even flat out wrong.
The Problem with BCAAs:
A recent meta-analysis of research conducted between 1985 and 2017 revealed zero human studies in which BCAAs alone were responsible for more efficient protein synthesis or improved athletic performance.
In fact, the meta-analysis detailed two studies which found that BCAAs decreased muscle protein synthesis and actually accelerated the catabolic rate of lean tissue. This means that muscle was being broken down faster than it could be repaired.
The catabolic state was so aggressive in the presence of BCAAs because the body was rapidly trying to derive the other essential amino acids to complete protein synthesis. Without a complete profile of essential amino acids, the body was left with no choice but to break down muscle to derive the six that were missing.
In other words, BCAAs do not work in isolation; all of the essential amino acids are required to complete protein synthesis.
The study concluded that the idea that BCAA supplements stimulate muscle growth or produce an anabolic response is entirely unwarranted. And that’s just the beginning. In addition to being ineffective for building muscle or faster recovery, BCAAs can also have deleterious effects on overall health:
High doses of BCAAs can deplete B vitamins. The utilization of BCAAs requires several B vitamin cofactors. This siphoning of B vitamins can disrupt the hundreds of other biological functions that require them including digestion, nervous system function, cognition, and hormone production.
An overabundance of BCAAs can hinder serotonin production. The BCAAs and tryptophan both use the same carrier system to get to the brain. This means an overabundance of BCAAs will disrupt the brain’s uptake of tryptophan and therefore create a shortage of serotonin. Low serotonin can cause depression, anxiety, sleep problems, carbohydrate cravings, attention disorders, and more.
BCAAs may cause insulin resistance and interfere with blood glucose regulation. Increased BCAA levels are associated with a high risk of metabolic disorder and insulin resistance, and may even predict the development of type 2 diabetes
Why EAAs Are Superior to BCAAs
Despite all of this, BCAAs are still essential for human health and actually serve as a good source of fuel for workouts.
They simply don’t build muscle in isolation.
You need adequate levels of all of the essential amino acids to optimize health and complete protein synthesis. Think of it this way: BCAAs begin the process of protein synthesis, and the other six EAAs complete the process.
This is why it’s best to choose supplements that contain all of the essential amino acids if you truly want to maximize performance, recovery, and well-being.
Health Benefits of Essential Amino Acids:
Muscle Maintenance: EAAs have significant muscle-preserving effects, especially when training in a fasted state. These include decreased indicators of muscle damage and the maintenance of a healthy inflammatory response.
Exercise Recovery: Supplementing with EAAs post-workout increases muscle protein synthesis and net muscle protein balance. This may stimulate faster recovery and reduce fatigue after training.
Appetite Regulation: Having a sufficient balance of amino acids may help normalize appetite because EAAs activate the brain cells that regulate hunger and satiety.
Cognitive Function: Appropriate levels of tryptophan are necessary to produce serotonin and optimize cognitive performance.
Improved Sleep: Amino acid supplementation has been shown to improve sleep and mood and reduce symptoms of depression.
Metabolic Health: Proper ratios of amino acids could increase red blood cell count, hemoglobin, hematocrit, and serum albumin. They can also lower fasting blood glucose, support better red blood cell formation, and improve glycogen replenishment
Fasting and Ketosis: Ingestion of high amounts of leucine triggers an insulin spike, which may “break a fast” and interfere with ketosis. However, this only happens when leucine levels aren’t balanced by the other EAAs, which help buffer the glycemic response. The insignificant insulin response from a supplement with the proper ratios of EAAs won’t interfere with fasting or ketosis, and might even make them easier!*
*The one exception is fasting for autophagy or cellular healing. In this case we support water fasting with nutrient dense re-feeds, where EAAs can be used in conjunction with healing foods. For the proposes of insulin and performance goals EAAs may be used in a fasted state pre, intra, and post workout with great success.
EAAs crush BCAAs as the best amino acid supplement, and their benefits go far beyond building muscle. EAAs are a true nutritional powerhouse that can help you optimize your training, recovery, sleep, mood, and so much more.
