Probiotics may have some benefits for people living with psoriasis. You can get probiotics through your diet or by taking supplements.

Probiotics are live microbes that are good for your body. Your body contains trillions of them. And every person’s collection of microbes, called a microbiome, is different.

Since the 1990s, scientists have been studying how gut microbes affect different conditions like psoriasis. Recent research suggests that taking probiotics may help improve the condition.

People with psoriasis often have higher amounts of inflammation-causing bacteria in their intestines. Adding beneficial bacteria to your diet might balance your intestine’s bacterial mix.

This is because probiotics stimulate your body’s T cells. Your T cells are responsible for regulating your immune system. They can also reduce inflammation.

Research on microbes and psoriasis is more recent. Earlier research suggests that probiotics can ease symptoms for people with:

Specific gut microbes may offer benefits to the body outside the intestines. For people with psoriasis, this may mean reduced skin inflammation.

One 2012 case study looked at the probiotic treatment of a woman with pustular psoriasis. Her psoriasis wasn’t responding to traditional treatments, so medical professionals explored other options.

She was put on the probiotic Lactobacillus. This is generally used in the production of yogurt, cheese, and fermented foods. Within 2 weeks, her lesions began to subside.

A 2013 study looked at the effects of the probiotic Bifidobacterium infantis 35624 on people with psoriasis. Researchers concluded that taking the oral probiotic reduced the biomarkers for inflammation.

Although there is promising evidence, the Food and Drug Administration (FDA) hasn’t yet approved probiotics to treat any disease. More research is necessary to find out which strains of probiotics are most helpful.

Adding probiotic-rich foods to your diet is an easy way to introduce these bacteria into your system. Probiotic bacteria are commonly found in the following:

  • yogurt
  • fermented cheeses, such as Gouda, cheddar, Swiss, and parmesan
  • sourdough bread
  • pickles
  • acidophilus milk

You may also consider taking a probiotic supplement. If you do take a supplement, consult your doctor. Together you can choose the best option and select an appropriate supplement for your needs.

Be sure to discuss any other medications or supplements you may be taking.

Traditional treatments for psoriasis depend on the severity of the outbreak, where it is on your body, and how well you respond to a particular treatment.

For light to moderate outbreaks, treatment usually starts with topical ointments and creams. These may contain corticosteroids, coal tar, or vitamins A or D.

Some topical treatments are prescription-only items, and others are available over the counter.

Healthcare professionals may treat more severe outbreaks with systemic drugs, immune suppressants, or biologics.

They may also use a combination of these medications. Phototherapy and laser therapies can also be effective when combined with other treatments.

When you have a psoriasis flare, take note of your overall status at the time of onset. This includes any medications you’re taking, any food or drink you’ve had, and any activities you may be participating in.

This will help you identify potential triggers.

Stress, smoking, and certain medications are known triggers. Some people also report that heat, certain foods, perfumes, or chemicals can set off a psoriasis flare.

If you decide to add probiotics to your psoriasis regimen, keep a log to record which probiotics you add and any results you experience. This will help you track any changes or improvements.

In the meantime, stick to your psoriasis regimen. Keep your skin lubricated and clean, use the recommended ointments, and take any prescribed oral medications on schedule.

If you experience any unusual symptoms, don’t hesitate to contact a doctor.
