Threonine is an essential amino acid that helps build connective tissues such as elastin and collagen. It also helps regulate muscle growth and can balance mood and digestion. Essential amino acids are not created by your body — they rely on diet to become part of your system. If you’re not getting enough threonine through diet alone, a supplement is a great aid to ensure your body stays healthy and functioning.
If you’re looking for the best of the best, Life Extension Magnesium L-Threonate has 2,000 milligrams of L-threonine per capsule and is made with raw ingredients for purity and quality.
Threonine, or L-threonine, is both an essential amino acid and a regulated protein in your body. Essential amino acids are not synthesized by the body, says Examine. It aids in muscle growth and helps strengthen cognitive functions such as memory. If you are lacking in threonine, you may suffer from mood swings, irritability, confusion and digestive issues. High-protein foods are a great source of threonine.
Once ingested, threonine changes to a chemical called glycine. Glycine works in the nervous system to regulate muscle growth, reduce muscle spasms and boost cognitive functions.
Threonine supports digestive health, muscle growth and strength, prevents fatty liver and may alleviate anxiety and depression.
A typical dose of threonine is anywhere from 150 to 500 milligrams daily. You may take them once daily or multiple times a day before meals. The dose and timing depends on your needs. Consult your physician to know what is right for you.
Threonine supplements come in powder or capsule form. If you have trouble swallowing or ingesting pills, a powder is a great option. However, powder needs to be mixed with liquid and may have a taste some consumers dislike.
Some capsules are made with gelatin. Gelatin is derived from animals and is not vegetarian or vegan-friendly. Check the supplement ingredient list to know if it is gelatin-free. If it’s not listed on the ingredients, go to the brand’s website for more information.
Threonine supplements are generally considered safe. Some people may experience mild side effects such as nausea, upset stomach, skin rash or headaches. It is not advised for women who are pregnant or breastfeeding to take threonine supplements. Also, people taking certain medications associated with Alzheimer’s disease should avoid threonine supplements as there may be negative drug interactions. Consult your doctor if you are concerned about potential side effects.
Threonine supplements range in price from $11 to over $20 depending on quality, form and quantity.
