What to do
Take probiotics with cool water on an empty stomach, not in coffee or hot drinks.
How to fit both into one day
Probiotic
morningempty stomach
Take probiotics on an empty stomach or 30 minutes before a meal — gastric acid is lowest then. Separate from antibiotics by two hours.
Putting Probiotic in the morning and Coffee in the evening satisfies the 0-hour separation without disrupting either one's absorption window.
