Kefir for better sleep?

Discover how this probiotic can help you get a good night's sleep

Sleeping well depends not only on having a relaxing nighttime routine, but also on what we eat. And in this regard, kefir—a fermented beverage rich in probiotics—can become a natural ally for improving sleep quality.

How does kefir help you sleep better?

Kefir is an excellent source of tryptophan , an essential amino acid that the body uses to produce serotonin and melatonin , two key neurotransmitters for regulating mood and the sleep-wake cycle.

  • Serotonin helps to calm the mind and improve emotional well-being.

  • Melatonin is known as "the sleep hormone" because it regulates when we get sleepy and how we rest.

  • Furthermore, studies have shown that the probiotics present in kefir can increase the production of GABA (gamma-aminobutyric acid) , a neurotransmitter that promotes relaxation and reduces anxiety, which also influences deeper and more restorative rest.

The gut-brain axis and the role of kefir

There is a direct connection between the gut and the brain, known as the gut-brain axis . A balanced gut microbiota improves neurological function, and probiotics—like those found in kefir—can modulate this axis, positively impacting sleep, stress, and anxiety.

Conclusion

Incorporating kefir into your daily diet, especially at night, can help you fall asleep faster and sleep better. Besides being a natural option, free of chemicals and side effects, its nutritional profile makes it a beneficial beverage for your mental and emotional well-being.
