We, as consumers, have no way of concluding whether this claim is correct. I assume the same can be achieved by using commercially available mainstream toothpaste in the market. not worth the time or the money, and inaccurate claim.

Glass jar (substantial thickness but not heavy) easily recyclable, great product. No refill packs available, so you have to buy jar after jar with plastic lids. These also contain fluoride, which was important to me.

Lighter than a small tube, and easy to detrrmine how much to carry. They are light, no waste, and no tube. It is so nice not having to deal with the end of the tube having residue or trying to squeeze out what little remains.

The label on the package is laughable if not an outright lie. Comes in a plastic bubble mailer and the glass bottle is too small to recycle. Tastes like an expired tums that your grandma finds in the back of her medicine cabinet.
