Ark Drops is a dietary supplement sold as a liquid tincture, marketed primarily as a “Breathe & Focus Formula” that claims to improve breathing, mental clarity, and athletic performance. The product is essentially a blend of mint oils in a carrier oil, sweetened with monk fruit extract. It is not an FDA-approved drug and has not been evaluated for the claims its manufacturer makes.
What’s Actually in Ark Drops
The ingredient list, recorded in the NIH’s Dietary Supplement Label Database, is short. Ark Drops contains peppermint oil, Japan mint oil, green mint oil, and an ingredient called “frosted mint.” These are suspended in a medium-chain triglyceride (MCT) carrier oil derived from caprylic acid, a common base used in supplement tinctures. Monk fruit extract is added as a natural sweetener.
There are no vitamins, minerals, adaptogens, or novel compounds in the formula. The product is, at its core, a concentrated mint oil blend you place on or under your tongue.
What the Manufacturer Claims
The company behind Ark Drops, ARK of Sweden, markets the product with language suggesting it can “increase strength, endurance, and muscle recovery” during physical activity. Their website states the drops are “formulated using research-based ingredients shown to enhance breathing, focus, and mental performance.” The marketing describes the sensation of taking the drops: “Your chest opens up. Breathing becomes effortless.”
These claims lean heavily on the well-known cooling sensation of menthol, the active compound in peppermint and related mint oils. Menthol stimulates cold receptors in the mouth, throat, and nasal passages, creating a subjective feeling of airway opening. This is the same reason menthol is used in cough drops and chest rubs. The sensation is real, but it reflects nerve stimulation rather than a measurable increase in airflow or oxygen intake.
As a dietary supplement, Ark Drops does not need FDA approval before being sold. The manufacturer is responsible for ensuring safety and the accuracy of its label, but the FDA does not verify supplement health claims the way it does for pharmaceutical drugs.
The Company Behind the Product
Ark Drops is sold through ARK of Sweden’s website, which positions the brand as Scandinavian in origin. A related UK entity, Drop Ark Limited, was registered in Watford, England, but that company was dissolved in December 2025 according to UK government records. The product continues to be sold through its US-facing online store.
Potential Side Effects
Because the active ingredients are concentrated mint oils, the side effect profile mirrors what’s known about oral peppermint oil. The National Center for Complementary and Integrative Health notes that peppermint oil taken by mouth can cause heartburn, nausea, abdominal pain, and dry mouth. Most side effects tend to be mild, but people prone to acid reflux may find that peppermint oil worsens their symptoms. This happens because menthol relaxes the muscle at the top of the stomach, making it easier for acid to travel upward.
Peppermint oil applied to skin or mucous membranes can also cause irritation or rashes in some people. Since Ark Drops are placed directly in the mouth, anyone with sensitivity to mint oils should be cautious with the product.
Does It Work as Advertised
The honest answer is that there’s no published clinical evidence specific to Ark Drops. The product’s marketing uses the phrase “research-based ingredients,” which refers broadly to studies on peppermint oil rather than to trials of the product itself. Peppermint oil does have some evidence supporting its use for irritable bowel syndrome symptoms and minor tension headaches, but those applications involve specific doses in specific formats (typically enteric-coated capsules for gut issues).
For athletic performance, the evidence is thin. A few small studies have explored whether inhaling menthol before exercise changes perceived exertion or breathing comfort, and some show a mild subjective effect. But “it feels easier to breathe” is different from “your body is taking in more oxygen” or “your muscles are recovering faster.” The marketing language blurs that distinction. The cooling sensation in your throat and chest after taking the drops is genuine, but it doesn’t translate to the kind of physiological improvements the branding implies.
At its simplest, Ark Drops is a flavored mint oil product in a convenient dropper bottle, sold at a premium price point with performance-oriented branding. If you enjoy the refreshing sensation of strong mint and find it helps you feel more alert or clear-headed before a workout or during your day, that experience is valid. Just know that what you’re getting is functionally similar to a high-quality peppermint oil you could buy for a fraction of the cost.
