5-HTP stands for 5-hydroxytryptophan, which is a dietary supplement used to treat a wide range of mood disorders and other issues.
Our bodies naturally make 5-HTP, but some people take extra to give their serotonin levels an added boost.
Serotonin is a neurotransmitter in our brains. It’s responsible for regulating our mood, sleep pattern and pain management.
Seen as a ‘happy pill’, 5-HTP supplements can be bought over the counter to treat a wide range of neurologic and metabolic diseases.
Although research is still ongoing, there is some evidence to show positive effects when treating:
It even plays a role in cognition, reward, learning and memory, making it highly sought after among people wanting to keep their brain and body in optimum health.
5-HTP is a relatively new supplement still undergoing research.
Tryptophan use has been associated with liver and brain toxicity, and eosinophilic myalgia syndrome (EMS).
This caused the FDA to ban the sale of all tryptophan supplements in 1989.
If you have high blood pressure or diabetes, consult your GP before taking these dietary supplements.
Good sources of tryptophan (a building block of 5-HTP) are:
Tryptophan is an essential amino acid.
When we eat foods containing tryptophan, our digestive system gets to work to convert it into 5-HTP.
5-HTP assists the central nervous system in transporting serotonin to where it needs to be.
This brings our levels of serotonin higher.
Serotonin is a precursor to melatonin  – a hormone which times circadian rhythms and helps you to fall asleep and wake up at the right time so you can feel rested.
Anecdotally, people have reported a few common side effects of taking these herbal supplements.
These often only result from prolonged use of a high dose, and include:
Ethanol is a main component of alcohol, and this can chemically react with herbal remedies and medications.
Anecdotally, you will find a lot of advice online telling you it’s a bad idea to drink while taking 5-HTP supplements.
Not enough research has been done for us to say definitively whether alcohol and 5-HTP are a dangerous combination.
Below we unpack some of the alleged reasons that this mix could be harmful.
Although you may get a temporary serotonin boost from drinking, alcohol depletes serotonin levels in the long run.
This means all of the good work your 5-HTP supplements have achieved so far is undone, and any problems you’ve been experiencing as a result of low serotonin levels can come back in full force.
Like antidepressants, mixing alcohol and 5-HTP can exacerbate the depressant effects of alcohol, making you more impaired more quickly.
Drug-induced hepatotoxicity is a liver injury that’s caused by drugs or herbal compounds.
Although there is no research available to show that this can occur in humans, there has been one case reported of a dog experiencing toxicity from 5-HTP.
Serotonin syndrome – also known as serotonin toxicity – is a serious and potentially deadly condition caused by too much serotonin within the synapses of the brain.
Symptoms of serotonin syndrome include:
This syndrome is still under investigation, but most cases can be cured by simply coming off the drugs or supplements.
Although there’s little research to suggest that combining 5-HTP with alcohol is the cause of liver problems, both 5-HTP and alcohol when taken separately can cause adverse effects on the organ.
Now, we’re learning that serotonin deficiency can negatively affect the liver too.
One study reported that activating the brain’s serotonergic system (which is the role 5-HTP plays) affects the regulation of the liver.
Therefore, if you are taking both HTP supplements and alcohol, you could be putting double the strain on your liver.
There’s a craze for mixing 5-HTP with booze to try to enhance the effects of alcohol and get more drunk.
However, for the reasons mentioned above, we strongly advise being cautious about this.
There is a theory that supplements which affect serotonin when taken with alcohol can be dangerous.
The results of mixing serotonin-regulating medication and alcohol is still being measured, but scientists believe it could have something to do with the way serotonin levels mediate alcohol’s effects on the brain.
The process by which our brains pass messages to our central nervous system is called serotonergic signal transmission.
When we drink alcohol, it changes the way our brains transport serotonin across neurons.
As 5-HTP boosts serotonin levels, the two chemicals can create a hormonal imbalance.
Other medications you should be wary of mixing with alcohol include:
Wait at least one day after you’ve taken 5-HTP before having your first alcoholic beverage.
This will ensure you don’t have a very high concentration in your system at the same time as alcohol.
If you’re looking to improve your mental health, therapy has some of the best success rates for beating mental health conditions.
The NHS reports that 66.4% of patients showed reliable improvement after undergoing psychological therapy.
Successful types of therapy include:
Exercise has been proven effective at treating a wide range of mental health issues.
And the good news is, you don’t need to break a sweat. Even walking for 20 minutes three times a week is enough to feel the benefits.
You could try:
Mindfulness simply means being present in the moment, and being aware of your thoughts, feelings and senses.
Mindfulness can significantly reduce depressive episodes.
This can include:
Serotonin syndrome or serotonin toxicity is a condition caused by excess serotonin levels within the brain’s synapses.
The increased levels of serotonin cause a hormonal imbalance that can result in:
Currently, there aren’t any supplements that are proven safe to consume alongside 5-HTP.
Be careful taking 5-HTP with any other remedy that causes drowsiness like poppy, chamomile and catnip, as this can cause you to feel too sleepy.
You should never drive under the influence of a sedative, as this can be dangerous, so it’s not recommended to drive after taking 5-HTP.
It’s illegal in the UK to drive if you are over the limit, so driving after you’ve had too much to drink is another big no-no.
Alcohol use disorder encompasses alcohol abuse, dependence, addiction and ‘alcoholism’.
It’s an illness where people struggle to control their use, think about alcohol a lot and keep drinking even when it’s causing problems in their life.
One study showed a reduction in alcohol intake in rats treated with 5-HTP.
However, more research will need to be completed in humans before we can definitively say that this is an effective treatment for alcohol dependence.
If you are looking to reduce your alcohol intake or recover from alcoholism, we can help.
