Essential amino acid
5 out of 5 stars
Essential amino acid
I ordered this Natural Factors L lycine because it is an essential acid that the body cannot produce and has many benefits when it's added to your diet. I've used many supplements from this brand Natural Factors before and never had any issues so I trust them still. These capsules are huge so for anyone who has an issue swallowing capsules you may need a pill cutter as they are tablets. The bottle has an easy access flip cap. The label suggests two capsules 3 times a day so I just pair it with a meal. So far I have not experienced any negative side effects. There's no requirement to refrigerate after opening but just to keep it in a cool and dry place. The expiry date is four years away. I like how it's non gmo and lab tested for quality assurance. It says it's formulated and packaged in Canada but does not state where it is actually made.
Thank you for your feedback

    I have been taking these at night and do not notice any significant difference, to anything.
    Maybe I have to take it long-term to notice anything.
