Research

The science behind the superfood.

Our belief in kefir isn't just tradition — it's backed by a growing body of scientific research. Kefir has been studied for thousands of years of traditional use and, more recently, in laboratories and clinical trials around the world. Here's an honest look at what that research shows.

A note on honesty: kefir is a wholesome food that supports wellness as part of a balanced lifestyle. It is not a medicine or a treatment for any condition. Where the science is strong, we say so; where it's still emerging, we say that too. If you have a health concern, please speak with your doctor.

Gut & digestive health — the strongest evidence

Kefir's rich probiotic diversity enhances intestinal balance and lactose digestion. Many of its bacteria are hardy enough to survive the harsh conditions in your gut, meaning they arrive where they're needed most.

Bone health — encouraging

Kefir is a strong natural source of calcium, delivering roughly 30–40% of the recommended daily intake in a single glass. A six-month clinical trial in patients with osteoporosis found that kefir combined with calcium improved measures of bone turnover and bone mineral density more than calcium on its own.

Skin health — a fast-growing field

The link between gut and skin is one of the most exciting areas in modern wellness. In one of the first studies of its kind, drinking kefir was shown to strengthen the skin's barrier and noticeably improve skin hydration in both healthy and eczema-prone volunteers. Research into topical probiotics — the science behind our masks and scrubs — shows they can support the skin's microbiome and barrier, with promising early findings for calming, blemish-prone, and sensitive skin.

Research on kefir is active and growing. We'll keep this page updated as science develops.
