Can you die from a melatonin overdose?
If you’re asking yourself this question, you have probably been trying to assist your sleep with some supplementation.
Lots of people take melatonin pills to fall asleep quicker and in a more relaxed manner when they are stressed out. What is more, a lot of them would even go over the allowed and recommended amount to induce quicker effects.
If you are one of them, you are probably asking yourself whether or not this could lead to any potentially dangerous consequences. That’s what we are going to address, so let’s skip right ahead.
The vast majority of people tend to believe that this supplement is a safe sleep aid. To be completely honest, the fact of the matter is that it is a well-known and safe way to tackle a range of different health condition, not just troubled sleep.
This is mainly because this is a hormone which is produced naturally by your body. It is also important to note that it isn’t nearly as powerful as a lot of the prescription assisting options out there. Even though the synthetic alternative is somewhat similar to the one which is produced in your body, it doesn’t come without its risks. Just like any other medication, you need to make sure that you are careful enough, even if it is available over the counter.
But, can you OD on melatonin?
To sum it up – melatonin is not known to be a potential cause of death, but you need to be aware that it could lead to certain complications if you overdose.
Melatonin Pill Side Effects
Drowsiness is undoubtedly amongst the most visible and common side effects when it comes to overdoing it with your supplementation. The idea is that if you take this supplement at the wrong time of the day, you are likely to start feeling drowsy. This could also lead to increased risks when you are operating certain heavy machinery or when you are driving, for example.
You are taking a hormone – hormonal changes are bound to happen. However, this could be far more serious than you think. For instance, women who undergo pregnancy are not advised to take melatonin as it could impact the growth of their fetus in a harmful way.
It is also something that could potentially reduce the libido of both sexes. It is capable of interfering with the sperm count of men and the ovulation cycles of women. With this said, if you are trying to have a baby, you should probably stay away from this supplement.
Another widespread consequence of taking a little bit too much of your melatonin pills is a severe headache in the morning. Keep in mind that this hormone is produced in your brain and as such, any immediate effect beyond what’s comfortable and what’s not for the body could quickly spiral into a tremendous headache.
Dizziness could easily come as a significant side effect of dosing off on melatonin. It could also be triggered by an allergic reaction to the supplement that promotes the production of this hormone. This is something quite unpleasant, and it is capable of severely disrupting your functioning.
If you take a seriously more substantial overdose, you could quickly start experiencing delusions, paranoia, confusion, hallucinations. Additionally, the feeling is being fueled by the disorientation that you get, and this is undoubtedly something that you shouldn’t be looking forward to.
This is undoubtedly one of the most common side effects of melatonin, regardless of whether you take it in a regular amount or you overdose it. You may easily experience stomach issues such as diarrhea, vomiting, and nausea. These are quite unpleasant, and this is something that you don’t want to deal with.
Anxiety & Depression
Anxiety, as well as depression, are also capable of being induced by the hormone. Keep in mind that they are commonly associated with severe hormonal imbalance and sudden changes which you could go through if you started taking melatonin.
How Much Melatonin is Too Much?
How Much Should You Take?
Now, this would seriously depend on the age of the one who is taking the supplement. Usually, adults are advised to dose the product between 0.2 mg to 20.0 mg. This is, of course, depending on the purpose that you want to achieve with melatonin. Of course, people are known to take more than that without any serious issues as there are a lot of individual factors involved. So, it is best if you talk to your doctor in advance.
This is a dosage which is quite common and should be somewhat mild. It is usually taken to handle sleep disorders in people who are blind. The dose of 10mg is taken before bedtime, and the entire treatment usually goes for about nine weeks.
This is a formidable amount of the hormone, and it should be used for specific serious purposes. For instance, if you want to combine conventional therapy for solid tumors with melatonin, you can take up to 40mg alongside radiotherapy. Of course, medical supervision is necessary.
The 30 mg melatonin dosage is substantial. As such, it is usually used to prevent and to treat lowered clot-forming cells. This is usually associated with cancer chemotherapy. The usage of melatonin continues throughout the entire therapy.
This is a serious dosage, and it shouldn’t be used at all. With this in mind, it’s important to note that this would result in a lot of unwanted effects which could be potentially very harmful. Keep this in consideration.
