Supports overall health
5-HTP is crucial for the body's serotonin production, positively affecting the nervous, immune, and hormonal systems. It aids in reducing stress and improving sleep quality while decreasing susceptibility to infections during the cold season. Proper dosage is important, and although it's effective, one should consider their health needs and consult a doctor if necessary.

Positive mood change

I am 17 and have been taking this for two weeks, combining it with various nutritional supplements. It's excellent and has had no side effects for me. In just two weeks, I felt the difference. I used to feel cold, frustrated, and depressed. With this product, I became more positive and happy, which has positively impacted my studies as I’m in my final year of school. I recommend consulting a doctor before starting any new supplement regimen. Thank you, iHerb, for the speedy delivery.

Antidepressant alternative
3 people found this helpful
This product is extraordinarily effective—one pill eliminated my depression that had persisted even while I was on prescribed antidepressants since 2003. I stopped my medication cold turkey, and thanks to 5-HTP, I experienced no withdrawal symptoms. I highly recommend it, especially in combination with L-Tyrosine.

Seasonal mood relief

There’s a positive effect on my seasonal depression, particularly in autumn. Though it doesn't completely uplift my mood, my sleep has improved, and mood swings are less severe. I’ve experienced no side effects and would recommend it for anyone struggling with the gloom of the season. Stay healthy!
