Larine: remineralizing oral care with hydroxyapatite

Larine is an oral care brand that sells products formulated to support enamel remineralization. Its catalog is built around hydroxyapatite, the mineral that, according to the company, makes up 97% of tooth enamel. The proposition is presented as a fluoride-free and sugar-free alternative, compatible with the oral microbiome.

Products and formats available

The store offers four main lines, each designed for a different moment in the daily routine:

• Remineralizing Gum: formulated with nano-hydroxyapatite and xylitol. Available in flavors such as mint, ginger, cinnamon, berry, extra hydroxyapatite, mastic, peppermint, bubble gum, pumpkin spice cinnamon, candy cane peppermint, watermelon, fruit punch and piña colada. Some flavors are seasonal or limited edition.
• Remineralizing Toothpaste: combines hydroxyapatite with probiotics.
• Remineralizing Mints: also with hydroxyapatite and probiotics, designed for care on the go.
• Remineralizing Pouches: a recent addition to the catalog.

The company also sells an Enamel Starter Kit, a starter set that includes several of these products and that, according to the site information, includes a free bamboo toothbrush and a travel bag.

The Natural RMX50 Complex system

Larine builds its offering around the Natural RMX50 Complex, a proprietary enamel support system built around hydroxyapatite. The brand presents its routine as a response to continuous enamel erosion: if brushing is done twice a day, habits such as coffee, meals and snacks take up the rest of the day. That is why it proposes three complementary products for different moments: toothpaste in the morning and at night, gum throughout the day and mints for when you are away from home.

Shipping and return policy

Orders are processed in a warehouse located in the United States and ship within one to two business days. For customers within the United States, estimated delivery is 7 to 14 business days. The company also ships internationally to most countries, with typical delivery times of 7 to 21 business days depending on the destination. All orders include tracking information. The return policy allows you to request a full refund within 30 days of purchase.

Subscriptions, wholesale purchases and support

Larine offers a subscription program with discounts of up to 25% on recurring orders. For wholesale purchases, such as family packs or gifts, the company directs customers to its wholesale sales page or to the contact email address. Customer support is handled through that same address.

Reported data on use and satisfaction

According to an internal survey of 128 customers conducted in June 2026, 73% use Larine products daily, 86% use them four or more times per week, 75% plan to keep buying them, 69% would recommend them to family or friends and 51% report a longer-lasting feeling of oral freshness. The company also states that more than 300,000 people have used its products and that 614 clinical professionals shared the brand on FrontrowMD without receiving compensation.

Product considerations

Most products are suitable for family use, although the company recommends adult supervision for children under six years old, for example to prevent them from swallowing gum. Each product's label indicates the recommended age. The site includes a notice stating that these statements have not been evaluated by the U.S. Food and Drug Administration and the products are not intended to diagnose, treat, cure or prevent any disease.
