Good Health High 5-HTP provides a high, 100mg dose of plant derived 5-HTP per capsule. 5-HTP is a precursor to serotonin, which is one of our 'feel good' brain chemicals. In the nervous system, serotonin has an important role in balancing stress levels and appetite, and supporting mental wellbeing and healthy sleep.

5-HTP is an organically-occuring amino acid which occurs in nature and is made naturally in the human brain. In supplement form, 5-HTP is sourced from the seeds of the Griffonia simplicifolia plant. In biochemical terms, 5-HTP precedes the creation of serotonin in the human brain, so this supplement is commonly taken to prevent serotonin deficiency and it's symptons, including anxiety, insomnia, depression and obesity.

Good Health High 5-HTP is our best-selling mood formula. It supports mental wellbeing and premenstrual emotional health, and helps manage carbohydrate cravings and emotional over-eating.


Adults: Take 1 to 3 capsules daily or as professionally advised. 

Warning: Do not exceed recommended dosage.


Not suitable for children, pregnant or breastfeeding women.

Should not be taken with prescription sleep medication, Parkinsons medication or Anti-depressants.

If symptoms persist, consult your healthcare practitioner.

Do not use if cap seal is broken.

Each Capsule Contains:

Herbal Extracts Equivalent to Dry: Griffonia simplicifolia (5HTP)  100mg

Contains No: artificial flavours, sweeteners, preservatives or colours used in this product.

I am so great full to my friend Lesley for telling me about 5HTP. I have been very low for the last 2 years. I have been struggling terribly in the last few months. I have a great job and don't want to risk losing it. I started taking 5HTP only a week ago and I cannot believe how much my spirits have lifted. I feel like the old me.

This is an amazing product that I started taking after seeing how well it worked on others taking it. I would not stop taking it now, as it has made a huge difference. I'm so glad I found out about this product and can get it easily and it is reasonably priced.

If the writers of the film, Grumpy Old Men, had found these High 5HTP capsules the movie would never have been produced. We call them Petes grumpy pills but, in reality, they are anti-grumpy and we always can tell if he has forgotten to take them! Got a grumpy grandpa? Buy him these as a special, loving treat!

  • star

I just started using 5-HTP for a few weeks and I have felt more 'emotionally balanced' and less irritable, in a calm and rational state of mind to deal with things. 5-HTP is a great product to promote an increase in serotonin naturally -- I have a noticeable difference in mood when I'm taking it compared to when I'm not. Definitely worth a try if you do not want to take an SSRI.
