1-2 billion CFU (spores) daily. The IBS-D and gas/bloating trials used 2 x 10^9 CFU/day of MTCC 5856 (LactoSpore); the GBI-30 6086 (BC30) studies used 1 x 10^9 CFU/day.

Tablet or capsule delivering a named strain — MTCC 5856 (LactoSpore) for IBS, GBI-30 6086 (BC30) for the exercise and amino-acid claims
Taken per lactose-containing meal, not as a daily dose. Trials gave 3,000 to 11,250 units of lactase (mostly FCC units) immediately before or with a single dairy or lactose challenge. One 2022 trial used 4,662 FCC units and describes 4,500 FCC units as the amount in the EU-approved health claim. More lactose needs more enzyme: 50 g of lactose given in water overwhelmed about 6,000 units in one trial. Products differ, so dose by the enzyme units on the label rather than by tablet count.
With meals
Lactase tablets, capsules or chewables labelled in FCC units, taken with dairy
