What are the health benefits of drinking acidophilus milk?

Quick answer

Acidophilus milk is cow's milk with Lactobacillus acidophilus added. It has the nutrition of ordinary milk, and some people find it easier on the stomach, but strong health claims are not settled. The NHS says probiotic evidence is limited, so treat it as a food, not a remedy.

What are the health benefits of acidophilus milk?

Acidophilus milk is milk to which the bacterium Lactobacillus acidophilus has been added. Like ordinary milk it provides protein, calcium and other nutrients, and the amount depends on the fat level and brand, so read the nutrition panel. The extra feature is the live bacterium.

What does the research say?

Common claims are better digestion, easier tolerance for people who struggle with lactose and general gut support. The NHS says evidence for probiotics is limited: they may help restore gut bacteria after illness or treatment and may ease irritable bowel syndrome symptoms, while claims beyond that have little support. Individual responses to lactose vary, and some people tolerate it better than regular milk while others do not.

Sweet vs fermented acidophilus milk

Type Taste Notes
Sweet acidophilus milk Tastes much like regular milk Often sold low-fat; one US label example is 1%
Fermented acidophilus milk Tangy, like kefir or yogurt Drink plain or use in smoothies

Who should be careful?

  • People with a milk allergy should avoid it; it is dairy.
  • People with a weakened immune system or a health condition should speak to a doctor before using probiotic products, as the NHS advises.
  • If you are lactose intolerant, try a small amount first.

How to buy and store it

  • Look for “Lactobacillus acidophilus” in the ingredients.
  • Keep it cold and drink by the date on the carton.
  • Shop-bought probiotic foods may not contain the stated bacteria in the stated amounts, the NHS warns.
