What is it?
Alanine is a nonessential amino acid used by the body to build proteins.
Alanine is present in prostate fluid, and it may play a role in supporting prostate health. One study, involving 45 men with benign prostatic hyperplasia (BPH), found that 780 mg of alanine per day for two weeks and then 390 mg for the next two and a half months, taken in combination with equal amounts of the amino acids glycine and glutamic acid, reduced symptoms of BPH;1 this work has been independently confirmed.2
Where is it found?
As with the other amino acids, excellent sources of alanine include meat and poultry, fish, eggs, and dairy products. Some protein-rich plant foods also supply alanine.
Alanine has been used in connection with the following condition (refer to the individual health concern for complete information):
| Rating | Health Concerns |
|---|---|
 |
Benign prostatic hyperplasia (in combination with glycine and glutamic acid) |
Reliable and relatively consistent scientific data showing a substantial health benefit. Contradictory, insufficient, or preliminary
studies suggesting a health benefit or minimal health benefit. For an herb, supported by traditional use but
minimal or no scientific evidence. For a supplement, little scientific support and/or minimal
health benefit. | |
Who is likely to be deficient?
Since alanine is synthesised in the body and is also provided by most foods that are sources of protein, deficiencies are unlikely to occur.3
How much is usually taken?
Most people do not need to supplement with alanine; for those who do use this amino acid as a supplement, appropriate amounts should be determined with the consultation of a physician.
Are there any side effects or interactions?
Alanine is free of side effects for the vast majority of people who take it; however, people with kidney or liver disease should not consume high intakes of amino acids without consulting a healthcare professional.
At the time of writing, there were no well-known drug interactions with alanine.
