Do I take it with every dairy meal?

Just one capsule daily, following the product directions—no need to time a capsule with each dairy meal. Holy Cow is a consistent daily routine, not an instant lactase enzyme.

What’s inside my daily capsule?

Holy Cow combines a 16 billion CFU probiotic blend, including Bifidobacterium adolescentis, with XOS and D-ribose in one daily capsule. Explore the full ingredient list on the product label.

What research is behind Holy Cow?

Holy Cow features the same specific strain of Bifidobacterium adolescentis evaluated in the published human study. The findings apply to that strain—not every strain of the species or Holy Cow’s complete formula.

What does the 65% finding mean for me?

The studied-strain group reported 65% lower average combined daily symptom scores than placebo during the two-week study. It’s an encouraging finding—not a prediction of your individual results.

What should I know about the study?

The randomized, placebo-controlled study involved 21 adults over two weeks. Participants restricted milk and soft dairy during supplementation. The 65% finding compares average combined daily symptom scores of 1.04 for the studied strain and 2.97 for placebo; it is not the percentage of people who improved.

The lactose challenge did not show a significant improvement in breath hydrogen, a measure used to assess lactose maldigestion. The small, short study does not establish long-term outcomes or unrestricted dairy tolerance. Individual results vary; follow the product directions and pay attention to your own response.

Is Holy Cow intended for milk allergy?

No. Holy Cow is intended for lactose digestion support, not milk allergy. Ask a qualified healthcare professional about persistent symptoms or a suspected allergy.
