Cold Remedies: say bye bye cold forever Pop a Probiotic

The buzz around gut-friendly probiotics just got a little louder. Not only do some of the microorganisms combat gastrointestinal woes, but they can also influence your body's T cells, the crucial white blood cells that help power your immune system. According to recent research published in the journal Postgraduate Medicine, women who downed daily probiotics saw their T-cell count skyrocket, making them much less vulnerable to infections.
Though you can score some of the healthful stuff in a variety of foods like yogurt, miso, and tempeh, you're better off taking a 60- to 90-milligram supplement every morning during cold season, says lead study researcher Mira Baron, M.D., an internist in Cleveland.
