Dangerous supplement ....for sensitive people.
This caused a serious side effect in my son. About 1 hour after taking it he had severe back muscle stiffness and he couldn t bear the pain. Even with a muscle relaxant it took him 3 days to feel normal . Suggest not to be taken without doctor s supervision . Also the seller didn t take the product back after bringing to their notice , the side effect .

Life-Changing Supplement
I’ve been using NOW Foods L-Tryptophan 500 mg for a few months, and I am truly amazed by the difference it’s made in my daily life. I’ve struggled with anxiety and irritability symptoms for years, and this supplement has been a game-changer. Since I started taking it, I’ve noticed a significant reduction in anxiety and mood swings. I feel more relaxed, focused, and less easily frustrated throughout the day. What I love most is that it doesn’t cause any drowsiness or side effects – just a natural sense of calm and well-being. The capsules are easy to take, and the 120-count bottle lasts a long time, making it a great value. If you're dealing with similar symptoms, I highly recommend giving this a try – it’s been incredibly helpful for my mental health!
