In the jade roller–colored realm of wellness, where you can pick up $80 crystal water bottles, adorably packaged ceremonial-grade matcha, and reishi-infused wellness shots, there’s nothing like mānuka honey.
Made from the nectar of New Zealand’s mānuka tree, mānuka honey is prized for its antibacterial, antiviral, and anti-inflammatory properties. New Zealand’s Māori people have used the mānuka plant for medicinal purposes for centuries, but mānuka honey didn’t gain global popularity until the late 1980s after New Zealand biochemist Peter Molan’s discovery of methylglyoxal (MGO), an antimicrobial and antibacterial compound found in high concentration in mānuka honey. (Some honeys have it in trace amounts, but not nearly as high as in mānuka honey.) Today mānuka honey can be seen across Instagram slathered on skin to fight acne and recommended by holistic health practitioners for its ability to fight throat infections and help heal wounds.
A small jar of high-grade mānuka honey can run upward of $180, making it one of the world’s most expensive honeys. It’s also reportedly one of the world’s most fraudulently labeled ingredients.
According to a 2014 report by the New Zealand Ministry of Primary Industries, New Zealand produces about 1,700 tons of real mānuka honey each year, but over 10,000 tons of “mānuka honey” is sold on the global market. The truth is, that pretty jar of mānuka in your medicine cabinet might be adulterated or diluted with other honey. It might not be mānuka honey at all.
The mānuka flower blooms for only two to six weeks each year and only grows in New Zealand (and, according to Australia, Australia). Hives produce a limited amount of high-grade monofloral mānuka honey each season, driving prices up to $1,000 per kilogram. Those sky-high prices are one of the main reasons the product is frequently mixed with other honey and even synthetic chemicals. According to The Guardian, New Zealand’s historic case again Evergreen Life Ltd. earlier this year included 67 charges of alleged adulteration of mānuka honey with chemicals, including dihydroxyacetone, a chemical used in tanning lotions.
Inaccurate labeling is another rampant issue. Just last year, Trader Joe’s had a class action lawsuit filed against it for selling mānuka honey fraudulently labeled as 100 percent pure that tested between 57.3 and 62.6 percent mānuka honey. (There’s a motion to dismiss the lawsuit this month.)
Fera Science Ltd., a British research company that investigates and tests food products, found that mānuka honey sold in America was much lower quality mānuka than advertised on the jar. Manuka Doctor 20+ was shown to have such low levels of MGO that it didn’t even register on the test, suggesting that it was possibly not mānuka at all. Wedderspoon’s honey, which is labeled with the brand’s own grading system, “KFactor,” showed low levels of mānuka’s unique compounds. (The “KFactor” system measures a combination of properties, but not MGO.)
Labeling and terminology are two of the biggest hurdles consumers have to overcome when searching for a jar of authentic mānuka honey. “Labels with ‘Active’ and ‘KFactor’ can easily mislead consumers,” Sunil Pinnamaneni, Chief Technical Officer of Agritesting laboratories, tells Healthyish.
MGO, a measure of how much methylglyoxal is present in the honey, is the most widely known mānuka honey grading system in the United States. The higher the MGO rating (it maxes out at 1000 mg, which is where things get pricey), the higher the antibacterial strength in the honey. However, MGO grades are determined by the company selling the honey with no third-party market authentication.
