Anyone here take high doses of Vitamin C and lysine?

 sorry i was confused about the lysine. i wonder where you saw the info. it looks like there are a lot of sites that talk about it in conjunction with other issues besides the heart

Hello I take Lysine and Vitamin c but not in high doses Please have your dosage checked if you are self medicating high doses of vitamin C are not good for heart problems ot Lysine.  Moderation is the key for Lysine and vitamin C to work for boosting the immune system.  Have your Dr check you frequently to make sure that you are not overriding your own immunity with the high doses of the Lysime and Vitamin C.  High doses of either may cause a conflict that they decrease the immunity to some degree for disrupting the neurotransmittal system or the menengeal concept if taken in correctly and can cause heart arrythmia and other symptoms if taken incorrectly over time.  Again Moderation is the key although I have had success with Lysine and Vitamin c in Moderation in immunity.  Take Care, and have a good day.
