What are the potential side effects of consuming acidophilus milk?
We found no official source on side effects of acidophilus milk itself. The NIH's NCCIH says probiotics, which include Lactobacillus, have a long history of apparently safe use, but the risk of harm is greater in people with severe illness or weakened immune systems.

Does acidophilus milk have side effects?
We found no official page that lists side effects of acidophilus milk specifically. The closest official source is the NIH National Center for Complementary and Integrative Health (NCCIH) on probiotics, which names Lactobacillus as one of the most common probiotic groups and says probiotics can be found in yogurt and other fermented foods.
What does NCCIH say about probiotic safety?
Probiotics have a long history of apparently safe use, mainly in healthy people, but few studies have looked closely at safety. NCCIH says few side effects were reported in studies, and that solid information on how often and how severe they are is lacking.
What harms are possible?
- Infections
- Harmful substances made by the probiotic microbes
- Transfer of antibiotic resistance genes to other gut microbes
- Contamination: some products contain microbes not listed on the label
Who should be careful?
- People with severe illnesses or weakened immune systems, where the risk of harm is greater
- Premature infants: severe or fatal infections have been reported, and the FDA has warned health care providers
- Seriously ill hospital patients
NCCIH advises talking with a health care provider before taking a probiotic supplement, especially if you have health problems. Ask a doctor or pharmacist if you are unsure.
What we did not confirm
We did not find an official source for bloating, gas or allergy claims about acidophilus milk, so we do not list them.
