Effective and Easy to Take
These are great! I use them to help prevent cold sores. It’s difficult to find lysine in capsule form, especially at all affordable price. They digest so much easier than tablets. I keep reordering these. The smaller size is convenient too, easy to swallow.

Works fast! Like in 10-15 minutes!
Works so fast! I bought a more expensive one this month and instantly regretting it. Thorne brand literally works in ten minutes while this other brand takes over an hour and it was more expensive. I love Thorne supplements and I’m sticking with this brand moving forward. Can’t wait to repurchase.

Quality and safety
I’ve done a lot of research on supplement quality, and Thorne consistently ranks among the best. They use high-quality ingredients, follow rigorous manufacturing standards, and perform extensive testing for purity, potency, and contaminants. While they’re not the cheapest brand, I feel the quality, safety, and consistency make them well worth the investment. I specifically use Lysine to prevent reoccurring cold sores and it works!
