Amino acid supplements are, like herbs, largely unstudied and unregulated; thus, as a group, their safety and efficacy cannot be assured. Still, Americans are downing them for undocumented promises, ranging from building muscles to calming jittery nerves. Last year, amino acid supplement sales rang up about $400 million in the United States, estimates Euromonitor International.
Should anyone be taking amino acid supplements? There is certainly no health reason to do so, according to many experts. The body does need amino acids, which it uses to build proteins and to make other vital molecules including those that send messages in the brain. However, most Americans are highly unlikely to face a shortage. Of the 20 amino acids that make up animal and plant proteins, the body can manufacture all but 9. And all of those 9—histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine—are typically plentiful in the diet in the form of proteins.
Nearly all Americans eat the RDA for protein many times over. Thus, people are not popping amino acid supplements because they are worried about meeting their protein requirement. They are after druglike effects. Some are amateur bodybuilders looking for legal, muscle-building alternatives to steroids (illegal drugs derived from the male hormone testosterone that are believed to increase muscle size and power). Others are less concerned about brawn than brain: They take high-potency supplements of single amino acids to give them more energy, calm them down, or even make them smarter.
Do They Work?
Many of the claims have logic behind them. Amino acids make up proteins and proteins pack muscle, so it is theoretically possible that some amino acid mixtures could help increase muscle mass. However, they certainly will not have that effect in the absence of weight training or other muscle-building exercises. And even when combined with exercise, the evidence that amino acid supplements are beneficial is tenuous at best, top scientists say. A more likely effect of taking such supplements, they add, is nitrogen-rich urine, since amino acids contain nitrogen.
Taking large doses of single amino acids could, in some cases, affect the brain, experts say. Overloading the body with a single amino acid can cause more of that amino acid to enter the brain, where it may be used to make neurotransmitters, chemicals that carry messages between brain cells and influence mood. For instance, the amino acid tryptophan is used to produce the neurotransmitter serotonin, which can have a calming or sleep-inducing effect. And a few studies suggest that tryptophan can have a sedative effect on humans; it may also suppress appetite. But consumers no longer can find this supplement on store shelves. The FDA banned its sale because of the substance's potential toxicity.
Although some amino acids may turn out to be useful drugs, the evidence supporting their purported effects is still slim. And some of those claims are downright fanciful. For instance, experts discount the possibility that any amino acid supplement could influence such a broad-based brain function as intelligence. Even for amino acids such as tryptophan that may indeed alter mood, no one knows what the effective—and safe—doses are.
Are They Safe?
Indeed, the biggest question about amino acid supplements is safety. In humans, short-term studies have shown that high doses of some amino acids are safe—up to a point. To date, however, scientists have not established safe intake levels for any amino acid.
Animal studies have suggested that amino acids may be harmful. In large doses, single amino acids can depress the growth of lab animals, change their brain chemistry, and cause damage to organs such as the pancreas and kidneys. The reason, experts say, is that a particular balance of various amino acids is crucial for the health of many body organs; thus, taking a lot of one amino acid can upset this balance and damage organs from the liver to the brain.
At least two amino acids in dietary supplements have been associated with serious injuries in healthy people, according to the FDA. The use of phenylalanine has been linked to various ailments including scleroderma, a disease in which fibrous connective tissue accumulates in the skin and often internal organs.
But the most famous example of amino acid toxicity is the tryptophan scare of 1989. That is when public health officials tied tryptophan supplements to an outbreak of a rare, painful muscle disease called eosinophilia-myalgia (EMS) that sickened 1500 people and killed 38. Studies later suggested the illness was due to impurities in a particular tryptophan product. However, the FDA has not ruled out tryptophan as the cause.
