Klyyr vs. GuruNanda.

Quick answer

Klyyr vs GuruNanda compares two fluoride-free hydroxyapatite pastes with different jobs. GuruNanda's Sensitive Toothpaste leads with 5% potassium nitrate, a sensitivity active, and lists both calcium hydroxyapatite and nano-hydroxyapatite without saying how much. It adds six essential oils, arginine, and vitamin K2.

Klyyr One+ publishes a combined 10% nano + micro hydroxyapatite blend, contains no potassium nitrate, and is not a desensitizing drug. Both are SLS-free. GuruNanda uses hydrated silica and two surfactants; One+ lists no silica and one surfactant.

01 How much hydroxyapatite is in GuruNanda toothpaste?

GuruNanda does not publish a hydroxyapatite percentage for its Sensitive Toothpaste. Its separate Toothpaste Booster lists 15% nano-HAp, but it is added on top of toothpaste. One+ discloses 10% nano + micro.

02 Does GuruNanda toothpaste have fluoride?

No. The Sensitive Toothpaste is fluoride-free, like One+.

03 Why does GuruNanda contain potassium nitrate?

Potassium nitrate is a common sensitivity active. GuruNanda lists 5%. One+ does not contain it and makes no desensitizing claim.

04 Is GuruNanda SLS-free?

Yes. It uses cocamidopropyl betaine and sodium cocoyl glutamate. One+ uses sodium cocoyl glutamate only.

05 Is GuruNanda or Klyyr better?

No head-to-head trial is cited here. The measurable differences are the sensitivity active, HAp disclosure, silica, and flavor system.
