What is it?

Amino acids.

You build 280,000 different proteins from 22 amino acids. 9 of which must come from your diet or supplementation. Click To Tweet

Amino acids are the raw material used to create, grow, and sustain life.

Most of us don’t get enough of certain amino acids, and too much of others. Our biology works with the resources available and throttles mental and physical performance as necessary.

Supplementation is a way to even the ratio of imbalanced aminos, orchestrating and harmonizing the body's many systems. Click To Tweet

Long-term amino deficiencies can result in degeneration and eventual disease. Whether world-class athlete, wellness enthusiast, or hard-charging executive, consuming more essential amino acids can give you an edge. This guide explains why amino acids are a top supplement virtually everyone needs more of, and how to get started.

The Nine (9) Essential Amino Acids

First, what even is an amino acid?

I wrote off amino acids in school because I didn’t understand them well. I like to think of them through two lenses:

  1. Quantity. When constructing a house, builders use large amounts of raw materials: stone, wood, brick, metal, glass, and plastic. Everything from the foundation to the roof is built from a catalog of raw materials. Each structure in the house requires multiple materials. Here, aminos are the materials, and together they make a structure (protein).
  2. Quality. For another analogy, think of Scrabble. Aminos are the letters in your hand. Combine multiple, and the word corresponds to a protein. The best hands include various letters. Such is the case with amino acids. You need specific amounts of each to build different proteins and perform your best.

In science terms, proteins are strings of amino acids. Frequently referred to as “the building blocks of protein”. Each individual amino acid is involved in different bodily processes, and some are currently considered more important than others.

Of the 22 total amino acids, your body can produce all but nine (essential) amino acids. Essential amino acids must come from either diet or supplementation. Protein-rich food contains different amounts of each individual amino. Animal proteins have particularly beneficial ratios of essential aminos.

Whenever your body wants to create something it does so through proteins. Proteins are made from different combinations and ratios of aminos. Thus, amino acids are the foundation of life. Click To Tweet

In fact, human genes are merely blueprints to build proteins. None of this building can occur without amino acids.

At one point plants may have provided enough. Historically, plant microbes always built the necessary amino acids. Collateral damage from pesticides and insecticides has decimated beneficial plant microbes (by interfering with the Shikimate pathway). Now, plants no longer contain the same levels of medicinal, alkaloid compounds. For more information on how this works, check out any of Dr. Zach Bush’s guest podcast appearances.

I advocate getting most aminos from your food. Then fill in any gaps with smart supplementation.

Who Should Take EAAs

Unfortunately, dietary protein lacks enough of certain amino “letters”. When your body creates new proteins, it has too much of some and not enough of others. Though you can survive and thrive on amino acids in food alone, peak performance requires more.

Essential amino acid supplements fill the gap.

Essential amino acid supplementation is for anyone looking to:

Aminos are the catalyst for nearly every chemical process in the body, such as enzyme production, hormone regulation, cognitive ability, neurotransmitter balance, and metabolism.

Virtually Everyone Needs More

Essential amino acids are an antidote to insufficient dietary protein intake. Even if you chow down drumsticks, rib-eyes, and wild-caught salmon, you’re likely missing specific amino acids critical for your brain and body to operate smoothly.

Most of us don’t get enough of the right amino acids.

The folks that stand to benefit most from supplementing EAAs include:

  • Vegans
  • The elderly
  • Athletes and hard-charging Type-A personalities

Some plants do contain all nine EAAs, but not in the right ratios of quantities. 

Essential amino acids are especially important for vegans because plants lack sufficient anabolic aminos like Leucine.

Other reasons to supplement EAAs include:

And consuming dietary protein rich in non-essential amino acids (NEAAs) can burden the liver and kidneys with additional harmful byproducts like ammonia and uric acid.

“An alternative insurance policy against low performance is to take a supplement containing the essential nine amino acids.”

An Athletic Super Supplement

In my years of competitive collegiate Rugby and Football, I vetted every compound available. I browsed the internet for any new promising compounds.

Early in my research, I came across amino acids. Before I understood the role of the other aminos, I mistakenly took BCAAs.

Studies of fitness supplements are muddied by a slew of problems, including two of particular interest: funding by vested parties, and studying a very different population. Little research on healthy, high-performance-focused folk exists.

Still, I came across study after study showing ergogenic effects of essential aminos. Competitive athletes and bodybuilders benefit in three main ways:

  1. Increases strength and endurance
  2. Staves off muscle tissue breakdown
  3. Prevents bonking, or “hitting the wall”

Here’s what one study had to say:

“[Aminos] can positively affect muscle mass, muscle strength, muscle power and VAT, counterbalancing more than one year of age-related loss of muscle mass and strength”

Other athletic benefits of supplementing EAAs include:

Essential Amino Acids vs. Branched-Chain Amino Acids vs. Whey

GrassFed Whey Protein Amino Acid Profile & Ratios
Good quality whey proteins should list the profile of specific amino acids (essential and otherwise).

The three most popular forms of dietary aminos are essential amino acids, branched-chain amino acids, and whey protein.

Each has different uses, but the amino content differs wildly:

  • BCAAs: 3/22 amino acids
  • EAAs: 9/22 amino acids
  • Whey: 18/22 amino acids, but in uneven and sub-optimal ratios

Unlike its three-amino acid cousin BCAAs, the nine-amino EAAs are more broad-spectrum and absorbable to the body. The best compound is only as effective as its absorption.

Old-school bodybuilders use BCAAs, but they’re behind the latest research. Branched-chain amino acids don’t work:

But what about essential aminos and whey?

Get the best of both worlds by combining whey protein and essential amino acids. To summarize:

  • EAAs > whey > BCAAs.
  • Avoid BCAAs.

Where to Get the Best EAA Supplements

Few companies make quality essential amino supplements. I’ve talked to manufacturers and scrutinized half a dozen products so far.

Here’s how to find the highest quality essential amino acid products and avoid common shady practices:

  • Check the ingredients. Avoid proprietary blends that hide what’s in the product.
  • Note of the amino acid quantities. They should be within five- to tenfold of each other.
  • Check for certifications. Third-parties should test the supplements for purity and accuracy.

Watch for products spiked with extra leucine. Leucine is cheap, and the shady products on the market fill most of their canisters with it. Effective formulations balance them. You can always buy an L-leucine supplement and mix it into your drink should you want fortification.

Expect L-Tryptophan to be well below the rest.

The only three EAA products I’ve found that match my standards are:

In my experience, NOW Amino-9 is the best value.

Though if you want to go down the natural route, I suggest a form of highly bioavailable amino acids called spirulina (see my post on the best chlorella and spirulina supplements to learn more).

How & When to Take EAAs the Right Way

Once I picked up an amino product (hopefully not BCAAs), I began wondering when I should take it:

  • First thing in the morning?
  • Before a run or workout?
  • Intra-workout?
  • Post-workout?
  • Mid-day?
  • Before bed?

Luckily, aminos fit anywhere into a schedule. For the physically active, the best time window to take essential amino acids is beginning 10 minutes before exercise all the way until the end. Unlike protein shakes, amino acids rapidly enter your bloodstream where they protect against the ravages of intense exercise.

  • For short exercise, I’ll take them just before.
  • For endurance events, I’ll have a serving 10 minutes before, and sip on another over the course of two hours.

If you follow a fasting routine, amino acids do partially break a fast. Specifically, activating mTOR inhibits the cellular recycling process called autophagy. But EAAs don’t cause the same insulin spike that BCAAs do and thus are a better choice. For most intents and purposes, a moderate dose of aminos will not detract at all from a fast and may enhance it.

Most of the research I’ve come across suggests doses between 5-20 grams of EAAs depending on your use case, diet, and lifestyle. However, they’re safe in large doses, and competitive athletes often take more to stay anabolic during grueling events.

Link Between Amino Acids and Disease

You may have heard that too much protein accelerates cancer and other degenerative diseases.

Evidence suggests that restricting certain aminos can extend the lifespan of lab animals.

Of the 21 amino acids, a newer study suggests restricting the following to slow aging:

  • Methionine
  • BCAAs (leucine, isoleucine, and valine)
  • Tryptophan

While increasing glycine correlates strongly with increased lifespan. Perhaps the rich glycine content explains the collagen supplement craze.

This article nicely breaks down the link between amino acids, proteins, and aging.

Essential Amino Acids: The Human Performance Enhancer

You wouldn’t live long without essential amino acids.

Your body cannot make them, so you must consume them in food and supplement. That’s where the “essential” part in the name comes from.

But today, most of us walk around with insufficient levels. We’re artificially limiting our brains and bodies by starving them of the nutrients needed to repair, regenerate, and grow.

I began taking aminos for sports performance and continued when I realized they made me feel better off the field. Click To Tweet

While amino acid deficiency is rampant, certain populations have an even greater need for supplementation:

  • The elderly
  • Vegan and vegatarians
  • Hard-charging executives
  • Athletes

Not long ago, we could get our essential amino acids through plants. Not anymore:

“Widespread use of pesticides kills the Shikimate pathway in plants, preventing them from producing biologically critical amino acids. Even supermarket produce is becoming devoid of protein.”

— Dr. Zach Bush

Have you tried essential aminos? If you’re a BCAA fan, give the broad-spectrum EAAs a try and report back. I’m eager to hear your results.
