Thank you! There are some commercial toothpastes (like Tom's of Maine [1]) and chews (like BasicBites [2]) that contain arginine. I expect we'll see it incorporated in more products soon.

RE: oral probiotics, there is some promising evidence of oral probiotics in improving oral health. We wrote a guide [3] based on the available research that might be helpful.

For lysine, we're still looking into the evidence, but we're excited to see more innovation and research into oral care product ingredients that work with the oral microbiome.
