Ensuring adequate calcium intake is one of the most effective ways to improve bone health and slow the progression of osteoporosis.

Full-fat kefir is not only an excellent source of calcium but also vitamin K2 — which plays a central role in calcium metabolism. Taking K2 through supplements has been shown to reduce the risk of fractures by up to 81%.
Recent animal studies have linked kefir to increased calcium absorption in bone cells. This leads to improved bone density, which should help prevent fractures.
2. Kefir may protect against cancer
Cancer is one of the leading causes of death worldwide. It occurs when abnormal cells in your body grow out of control, like in a tumor.
Probiotics in fermented dairy products are thought to reduce tumor growth by stimulating your immune system. So it’s possible that kefir may fight cancer.
This protective role has been shown in several lab studies. One older study found that kefir extract reduced the number of human breast cancer cells by 56%, compared to just 14% for yogurt extract.
Keep in mind that human studies are needed before any firm conclusions can be drawn.
3. Kefir may improve allergy and asthma symptoms
Allergies are caused by inflammatory responses to certain foods or substances. People with oversensitive immune systems are more prone to allergies, which can cause problems like asthma.
Animal studies have shown that kefir suppresses inflammatory responses associated with allergies and asthma, but human studies are needed to better investigate these effects.
