  • When you eat meat or other protein-rich foods‚ your body breaks it down into amino acids that are used to build other types of protein to help you function. One of these amino acids‚ known as L-threonine‚ is also responsible for helping your body produce more energy‚ keeping your liver healthy‚ supporting wound healing‚ and maintaining healthy tissues. Most people have enough due to their consumption of chicken‚ eggs‚ nuts‚ and cheese‚ you should have enough L-threonine. However‚ vegetarians who avoid animal products are at risk for a potential deficiency.

    When you don't have enough of this important amino acid‚ you can feel sluggish and have a harder time staying healthy. You may also experience symptoms of liver problems. Regardless of your situation‚ you may want to consider taking an L-threonine supplement if you follow a vegetarian or vegan diet‚ since these are often low in protein.

    L-Threonine 500 mg by Douglas Laboratories provides you with a convenient way to increase your levels of this important amino acid. This helps ensure that your body has enough proteins to keep your body functioning as it should. Taking this supplement might help your liver stay healthy‚ boost your immunity‚ and increase energy. L-threonine itself is the only active ingredient in this product‚ making it less likely to cause interactions with other supplements. Each capsule gives you 500 mg of L-threonine.

    One bottle of Douglas Labs’ L-Threonine contains 60 capsules‚ which should last for two months. Take one capsule a day‚ unless otherwise directed by your doctor.

    I Love this!

    I started taking L-Threonine by Douglas Laboratories the day they arrived....I take way too many muscle relaxers and finding one that doesn't put me into a coma (asleep) is hard to find. These do the job, although I don't find that the relief lasts very long (an hour, usually) I would still rather take these than the pain killer/muscle relaxers


      No sleepiness.


      Doesn't last long enough.

    I would recommend this item to a friend.
