Lysine is an amino acid that's naturally found in food and can also be taken as a supplement. Many people swear by lysine for its potential effects on cold sores, genital herpes, and other conditions, but you don't want to take it without considering the side effects. Here's what you need to know before taking lysine supplements.

Possible Side Effects

The most common side effects of taking lysine include nausea, diarrhea, and abdominal cramps. However, these symptoms are typically mild and will go away after discontinuing the supplement or reducing the dose.

In rare cases, some people may experience more serious symptoms such as dizziness or confusion. Before taking any supplement, make sure to consult your doctor first.

Can You Take Too Much Lysine?

Yes - like any supplement, you should not exceed the recommended daily dose of lysine unless instructed by a medical professional.

The recommended daily dose is usually between 500-3,000 mg per day depending on your individual needs and current health status.

Taking too much lysine can lead to high levels of calcium in your blood which can cause serious health issues such as kidney stones or even heart arrhythmias.

Will You Gain Weight With Lysine?

No - there is no evidence that taking lysine supplements will cause weight gain or loss in healthy adults.

However, if you're already overweight or obese then adding a few extra calories from lysine intakes may still result in weight gain over time if you do not adjust your diet accordingly to compensate for those extra calories.

Thus it's important to monitor your overall calorie intake when taking this supplement so that you don't unintentionally add more calories than necessary into your daily diet!

Who Should Not Take It?  

Those with kidney disease should not take lysine supplements without consulting their doctor first since it could worsen their condition due to its effect on calcium levels in the body.

Additionally, pregnant women should avoid using this supplement as there are no studies showing its safety during pregnancy and lactation periods yet!

Furthermore, if you have an allergy to any component within the supplement then stay away from it altogether just in case!   

Counter Indications

As mentioned above those with kidney disease should not take this supplement unless specifically instructed by their doctor first since it can increase their risk of developing complications due to its effect on calcium levels within the body!

Additionally, those who are pregnant or breastfeeding should avoid using this supplement since there isn't enough research yet proving its safety during these periods!

Finally, those with allergies should always check ingredient labels before consuming any product just in case they might be allergic to something within it!


Ultimately if you're considering adding lysine supplements into your daily regimen then it's important to talk with your doctor first about possible side effects and counter-indications related to this particular amino acid!

Additionally, make sure not to exceed recommended doses as too much of anything can lead to negative results including high blood calcium levels which could cause serious health issues down the road!

Finally, always read ingredient labels carefully before consuming any product especially if you have allergies just in case something might trigger them!   

Lysine is an interesting amino acid that has potential benefits for certain conditions but also has possible side effects that one should consider before taking it – so make sure to consult with a healthcare professional beforehand just in case anything goes wrong later down the road!
