If you want to try L. Plantarum yourself, get the strain 299v if you can. There's one by Jarrow (not affiliated, just made good experiences with it). AFAIK, most other strains of L. Plantarum produce D-lactic acid, while 299v produces L-lactic acid (I've even seen a paper where they used 299v to treat acidosis). D-lactic acid can be hard to metabolize and can lead to acidosis. Probiotics-induced acidosis is a thing - not good, most people with this end up in hospital and need infusions and some kind of intervention for the long term. Acidophilus generally produces D-lactic acid, while e.g. L casei shirota (Yakult) does not. It pays to take a hard look at the strains in a probiotic.
