What kind of interaction is it?

Timing-sensitive: the two substances can be taken on the same day but should be separated by a minimum time window.

Is this interaction backed by published research?

Yes. NutriStack lists 1 citation row for the Berberine + Lactobacillus acidophilus NCFM pair, each linking to PubMed by PMID where available. Full sourcing methodology at https://nutristackapp.com/methodology/interactions.

Berberine + Lactobacillus acidophilus NCFM

Q: Can I take Berberine and Lactobacillus acidophilus NCFM together?

Yes, if you separate them in time. Berberine and Lactobacillus acidophilus NCFM have a documented timing-sensitive interaction. Berberine antimicrobial activity may reduce viability of live NCFM if taken together.

Q: How does this affect a NutriStack Stack Score?

-5 to your Stack Score per scored timing-sensitive row.
