Neocate lcp vs neocate syneo

Wondering if anyone tried the 2 and if they've found synergy any better than lcp? My son us currently on LCP but his skin hasn't cleared, it's better but he's still so irritated. Because of various reasons he's had quite a few courses of antibiotics (not what I wanted at all but drs insisted he needed them) and I've read that early introduction to antibiotics can mess with his gut ! So now I'm eager to get some good bacteria back in and have read that synobiotics are good for reversing antibiotics damage. The drs have reluctantly prescribed Syneo now, they reallt didn't want to i guess its more expensive but I wasn't backing down ! Just wondered if anyone had any knowledge of the 2 and noticed any difference
