Hi XXXXXXX,
Thanks for writing to us.

It will be helpful if you please mention the indication for which you have started taking L-Arginine.

L-Arginine is an amino acid, which is not needed as supplement because it is normally synthesised in the body.

Low blood pressure is sometimes seen as side effect of L-Arginine. Low blood pressure can result in headache. So, it is advisable that you get your blood pressure and other vitals monitored.

I hope this is helpful to you. If you have any further query, I will be happy to help.
Regards. Thanks.
