Before we talk about the main benefits of 5-HTP, let’s just mention the importance of 5-HTP in our body.
As you might know, serotonin cannot cross the blood-brain barrier, so it has to be made within the brain.
However, 5-HTP is known for its ability to cross the blood-brain barrier (even better than tryptophan).
So that’s where things get interesting.
Let’s check out the main benefits of 5-HTP now.
1. 5-HTP Can Suppress Your Appetite
5-HTP is mainly known for its effects on your appetite.
Multiple studies show that supplementing 5-HTP can decrease your appetite, which results in weight-loss.
The appetite is suppressed by the increased feelings of fullness which 5-HTP triggers.
There is a study of 20 people with diabetes who were randomly assigned to receive either 5-HTP or a placebo for two weeks. The results showed that those who received 5-HTP consumed around 435 fewer calories per day, compared to the placebo group .
Another double-blind study on 25 subjected showed that a 2-week supplementation of 5-HTP (750 mg/day) to obese women and men was associated with less food intake and a significant weight-loss. 
To conclude, studies show pretty strong evidence that supplementing 5-HTP can suppress your appetite and help with weight-loss.
2. 5-HTP Can Help With Depression
Another very strong benefit of supplementing with 5-HTP is its power to help with depression by increasing the serotonin levels.
Those effects of 5-HTP on symptoms of depression have been well studied, especially how the 5-HTP increases serotonin level, which directly influences depression. [4, 5]
However, current research shows that while 5-HTP can be effective as an individual compound, combining it with other proven supplements is more effective for treating depression.
If you do have symptoms of depression, I do recommend consulting your doctor.
3. 5-HTP May Improve Your Sleep
As we already mentioned several times, 5-HTP produces serotonin, which can also be converted into melatonin.
Melatonin, however, is one of the crucial hormones that influence your sleep. It is increased in the evening to promote sleep and it decreases in the morning to help you wake up.
There is a study which showed that a combination of 5-HTP and GABA significantly reduced the time it took to fall asleep, increased sleep duration and improved sleep quality .
Another study showed that supplementing 5-HTP may also decrease sleep terrors in kids .
While more studies have to be done to know the recommended daily dosages, first studies show lots of potentials.

4. 5-HTP May Help Reduce Migraines
I’m now sure if you knew, but a lot of researches believe that migraines can be triggered by low serotonin levels .
Since 5-HTP increases serotonin, it could help to reduce your migraines frequency.
Actually, a study done on 124 people found that supplementing 5-HTP for 6 months significantly decreased the number of migraine attacks .
Again, if you have issues with migraines, I’d recommend talking to your doctor first, but keep in mind that 5-HTP might help you out.
5. 5-HTP Might Improve Symptoms Of Fibromyalgia
Last but not least, supplementing 5-HTP might improve your symptoms of fibromyalgia.
Fibromyalgia is a disorder characterized by widespread musculoskeletal pain accompanied by fatigue, sleep, memory and mood issues .
While we don’t know the exact cause of fibromyalgia, it is believed it’s related to low serotonin levels.
Early evidence shows that supplementing 5-HTP may improve typical symptoms of fibromyalgia .
More research has to be done to prove the early evidence, but it looks promising.
All right, we just covered 5 amazing benefits of supplementing 5-HTP.
But are there any side effects that you can expect by supplementing?
Let’s find out.
