Probiotics
Probiotic supplements: timing, strains, and survival
Survival through stomach acid usually matters more than the exact clock time.
Key takeaways
- Morning, 30 minutes before breakfast, on an empty stomach.
- Space at least 2 hours from antibiotics.
- Avoid hot drinks within an hour; heat kills strains.
- Match the strain to the goal, generic 'probiotic' is rarely the right answer.
What this category covers
Probiotics span Lactobacillus, Bifidobacterium, Saccharomyces, and Bacillus species, each with strain-specific effects backed by trials in specific conditions. The big four timing rules are the same across strains: empty stomach, no hot drinks immediately after, separated from antibiotics, daily consistency. Spore-forming species (Bacillus coagulans, Bacillus subtilis) are far more forgiving on all four counts.
How timing differs across probiotics
Most strains: morning, 30 minutes before breakfast, with a small amount of cool water. Spore-formers: with or without food, any time of day. If you take antibiotics, dose the probiotic 2 to 3 hours apart and continue for two weeks past the last antibiotic dose.

FAQ
Refrigerate or shelf-stable?
Refrigerated strains often have higher live counts at expiry. Shelf-stable spore strains travel better and are more reliable in heat.
How long until I notice effects?
For IBS symptoms, 4 weeks is a fair trial. For antibiotic-associated diarrhea protection, effect is concurrent.
Bigger CFU is better?
Not necessarily. Strain identity and trial-matched dose matter more than headline CFU numbers.
