I Was Introduced To These Supplements From A Company Called

I was introduced to these supplements from a company called Sisel. The supplements and information were given to me for my daughter who was born with small optic nerves, panhypopiruitarism and a seizure disorder which she takes daily meds for. I'm looking for a medical opinion on the supplements. From the research I've done, the company has a shady past and the literature is not backed by any studies or definitive medical facts (every other sentence is "May help" or "may improve." My question is would you medically recommend supplements like this for a child with health problems, decreased immune system and already taking daily meds?
