Research Update on Probiotics and Healthy Skin

There has been so much research on probiotics published that it’s hard to keep myself informed, and you as well. This week I’ll summarize three recent studies on probiotics. Let’s begin with research on probiotics and skin conditions.

Researchers examined the effects of three strains of probiotics on skin inflammation in mice: two strains of lactobacillus and one strain of bifidobacterium. Three groups of mice were given one of the probiotics for two weeks while two control groups were given a placebo. After two weeks, the skin of four groups of mice was chemically exposed to an irritant to cause inflammation while the fifth group was exposed to a control chemical.

The researchers examined both blood and skin of the mice for indicators of inflammation after seven days of exposure. The markers for inflammation were lower in the groups who took the preventive probiotics than either of the positive or negative controls. While this was a small study on mice, it did demonstrate that probiotics helped reduce the skin response to chemical irritation. This may be the first step in identifying a probiotic that could help conditions such as atopic dermatitis in the future.

Keep taking a wide-spectrum probiotic, especially if your skin has been less healthy than you want it to be. If you have a teen with skin problems, probiotics may make a big difference. Another research update on Thursday.

What are you prepared to do today?
