Can lysine cause weight gain?

I started taking L-lysine supplements recently for cold sores, but I'm also trying to watch my weight. My friend warned me some supplements can make you gain weight. Is there any truth to this with lysine?

As someone managing diabetes, I keep a close eye on every supplement. Lysine doesn't directly cause fat gain, but it can increase appetite in some people, which might lead to eating more. Keep tracking your daily food intake and check your blood sugar levels regularly.

I tried lysine for cold sores once and also noticed some slight weight changes, but it was mostly water retention. Drinking warm fennel seed water helped me a lot. But honestly, if you are gaining significant weight, check with your doc instead of trying more home remedies.

I totally get it, seeing the scale go up when you are trying to be healthy is so frustrating. Lysine generally doesn't cause weight gain on its own, but sometimes our body holds onto water. Give it a few days and see if it settles down.

I actually just finished a course of L-Lysine last month! In the beginning, I felt like my weight went up by a kilo, but it went back to normal once I completed the dosage. It is mostly temporary bloating, so don't worry too much.

Wait, really? I started lysine last week and I feel so bloated and heavy today. Has anyone else felt this same sudden weight gain within a few days of starting it? Please let me know, I am thinking of stopping it.

Oh god, I completely panicked when I started lysine because my scale showed a sudden jump! But my doctor reassured me that it doesn't cause actual fat gain. It just helps with protein synthesis and sometimes causes mild water weight which goes away soon.

Mere bhai, lysine toh ek simple amino acid hai, isse koi motapa nahi aata. Ha, thoda bhook badh sakti hai toh log zyada kha lete hain. Aap thoda dhyan rakho aur badhiya ghar ka khana khao, sab theek ho jayega.

Actually yaar, lysine directly weight gain nahi karata. Maine bhi use kiya tha gym ke time pe, standard supplements me hota hai. Agar weight badh raha hai toh maybe your diet or overall calories has changed, simple calculation hai.
