Laclede has had the generic version tested by independent labs. As the formula and use of enzymes is patented, and they have successfully defended copies for many years now. The CVS version has so few actual enzymes in it, that it was not worth their lawsuit. It isn't even serious competition of any sort numerically. It is worse than a cheap imitation, it is something that does not do anything that it represents. Probably why it is not wildly poular or takkng any market share from them.
As a side note the GSK corporation bought the Biotene brand last month. Laclede will still manufacture it for them, but the Biotene brand is now owned by GSK.
It is an expensive product, not because the Pellico family made millions of dollars in selling it, they never really did. Michael was a scientist that wished to do good in the world after his father died of cancer. It is expensive because the INGREDIENTS are so expensive. There have been few imitations because once someone realizes what it costs to make it (properly) they lose interest in how small the profit margin is compared to making a conventional product like other toothpastes and mouth rinses that do not contain enzymes.
If you want to use the CVS product it does have some of the qualities, the moisturizers etc. but it does not contain enough of the expensive enzymes, and certainly not the PBF protein product to actually keep your mouth healthy.
I wish to state for the record that I have no interest in GSK (stocks etc.) they are not contributors to OCF, (though I wish I could get them to be) and I have known Michael Pellico for what he is; which is a true humanist for decades. He still drives a 6 year old Toyota to work everyday, and has little interest in things material. He likes to tinker in his laboratory, makes veterinary products that are enzyme based as well for his sisters vet products company, and is working on a vaginal product that has the same qualities as the oral products, as that is an area that suffers dryness with age, and increasing risk from fungal (Candida) and other infections. He gives much of his money away to the needy. A model of a man that there are few like in the world.
I have no reason to promote these products except I know them to work in myself, and I know the measure of the man behind the idea.
