Outcomes where both Ceramides and L. plantarum 299v have evidence — compare verdict strength side-by-side.
350mg wheat-derived ceramides (the dose used in the cited trial) or 30-40mg glycosphingolipids daily (a typical label dose, not the dose used in the cited trials)
Once daily with food
Wheat-derived phytoceramides (Ceramide-PCD)
1 x 10^9 CFU (1 billion) daily taken WITH the iron-containing meal is sufficient for the iron effect — in the dual-isotope crossover trial 10^9 was significant (28.6% vs 18.5%, p<0.028) while 10^10 was NOT (29.1% vs 20.1%, p=0.080). The freeze-dried capsule and IBS trials used 1 x 10^10 CFU daily, and the pregnancy trial used 1 x 10^10 CFU twice daily (2 x 10^10 CFU/day)
