They are not that large and the other ingredients are excellent. I take all 4 at once. And they work. I've bought them many times now and will continue to do so. Review: Great to take everyday - Big pill to swallow! I use to prevent cold sores on my lips. Seems effective because It works! I just swallow it down with lots of water. No side effects.
