    Probiotics for healthy skin

    A side of kefir with your kombucha?

    Probiotics, which are helpful bacteria that protect the body from harmful bacteria, are literally everywhere. Strolling through the aisles of any grocery store, we can find yogurts, milks, juices, and other consumables that contain naturally-occurring probiotics such as lactobacillus or bifidobacterium, or foodstuffs that are artificially teeming with these celebrated organisms.

      I used to have a lot of acne on my face and back; after I've been taking probiotics, my skin, hair and nails are much healthier now. I've been reading more and more about these beneficial microorganisms in sites like http://bestprobiotics.org and articles found on this site.
