How you can Take Acidophilus Powder

January 26th, 2013

When you want to boost the “friendly” or “good” bacteria in your intestines, acidophilus powder is the most popular probiotic choice. As an over-the-counter supplement, Lactobacillus acidophilus, more commonly referred to as L. acidophilus, or acidophilus, has successfully prevented diarrhea caused by antibiotics and has had mixed results in treating general diarrhea, according to the University of Maryland Medical Center. Although it is generally considered safe for adults, check with your doctor before taking acidophilus, as it may have unwanted side effects or interfere with any medications or other supplements you are taking.

Step 1

Check the acidophilus powder for instructions on storing after purchase. Unless directed otherwise, store the powder in the refrigerator.

Step 2

Drink a full glass of milk, water or fruit juice after swallowing the powder in pill form. If you are taking the acidophilus in powder form from a packet or bottle, mix it into your food, or into a glass of milk, water or fruit juice.

Step 3

Take 1 to 2 billion colony-forming units, or CFUs, of acidophilus daily for diarrhea. Read the supplement’s label for exact dosing instructions as the amount of CFUs per pill and per bottle of powder vary from brand to brand. Common powder dosages range from 1/4 tsp to 1/2 tsp a day.

Step 4

Take 1 to 15 billion colony-forming units of acidophilus a day for intestinal health. If you are taking an antibiotic and are taking the acidophilus to treat diarrhea from the antibiotic, wait two to three hours after taking the antibiotic.

Tips and Warnings

  • People use acidophilus powder for the treatment of a myriad of conditions, including asthma, allergies and eczema, but it’s unclear whether the supplement successfully treats any of these conditions. Additional research is needed.
  • People who have taken more than 1 to 2 billion acidophilus cells a day reported side effects including gas, upset stomach and diarrhea, according to the University of Maryland Medical Center.

    Do not take acidophilus if you have intestinal damage, an infection or a weakened immune system. Do not take acidophilus if you have an artificial heart valve due to risk of bacterial infection.

    If you have a high fever, do not take acidophilus for more than two days, unless your doctor advises otherwise.

    Never give acidophilus to a child without first consulting your physician. Acidophilus may not be safe for children age 3 and under.

    If you are pregnant or breast-feeding, talk to your doctor before taking acidophilus.

    Acidophilus may interfere with other medications and supplements. Do not take acidophilus with the medication sulfasalazine.

    Never apply any oral form of acidophilus to your body. While says strong evidence suggests the topical application of acidophilus treats bacterial vaginal infections, you should only use the suppository form of acidophilus for this purpose.
