May not suit sensitive gut

Didn’t suit me. Indigestion and really bad heartburn. Noticed this happening after taking a few doses. I have sensitive gut so not for me!

So many benefits

L-Lysine isn't made in the body but is needed for wound healing and increasing energy. It produces carnitine, a nutrient responsible for converting fatty acids into energy by way of the mitochondria. I find the Vitacost L-Lysine to check all the boxes and is offered at a good price.

Excellent basic lysine at a good price

I bought this L-Lysine from Vitacost to support my immune system and collagen production in my joints and skin. The 500 mg dosage per tablet is very convenient—you can easily adjust your daily dose to suit your needs or a specialist's recommendations. The tablets are high-quality, the packaging is airtight, and the 300 tablets per serving are much more affordable than other brands. It's a great value for money.

It helps control herpes outbreaks

I feel that when I have a herpes outbreak, it goes away faster when I supplement with lysine. It's very effective; the bottle contains a good amount that lasts quite a while, the ingredients are high quality, it's beneficial, the formula is good, and I feel it has improved the quality of my skin.

Great deal

I take it twice a day. The tablets aren't too big, so they're easy to swallow. Plus, it's a great deal with 300 tablets.

Excellent!

Everything was hermetically sealed and well protected during delivery. The vitamins themselves look well-made and neat.

I buy lysine from iHerb. I've tried various brands, but I don't think there's any difference in effectiveness. This case is also large.
