Natch: Boombastic Postbiotic Mouthwash Tabs Refill

Boombastic Postbiotic Mouthwash Tabs Refill is a refill bag containing 62 mouthwash tabs designed to support daily oral care with convenient, water-free freshness. Powered by postbiotics, hydroxyapatite, zinc, and an intense double mint & bergamot blend, these mouthwash tabs help support a balanced oral microbiome while delivering long-lasting fresh breath.

Unlike traditional mouthwash, Boombastic Postbiotic Mouthwash Tabs Refill is alcohol-free and made without unnecessary additives. Hydroxyapatite helps remineralise and strengthen tooth enamel, while zinc contributes to gum care and helps neutralise odour-causing compounds. The formula is designed for easy everyday use at home or on the go — simply chew the tab, let saliva activate it, swish for at least 30 seconds, and spit out. No water required.

Each refill bag is designed to reduce plastic waste and can be transferred into a reusable Natch glass bottle to help maintain freshness. The formula includes ingredients such as xylitol, hydroxyapatite, Lactobacillus ferment, peppermint oil, spearmint oil, bergamot peel oil, and zinc citrate.
