Is this truly folinic acid? Or just folic acid?

Hi. Its Folate (as calcium folinate folinic acid)

Does anyone notice a difference between folinic acid and methylfolate?

Yes. Folinic acid helps me feel less anxious. Methylfolate does not have this effect for me, and helps me focus, most noticeably. I feel considerably better with methylfolate, while folinic acid has a more subtle effect. I am homozygous C677T and take both daily.

Glen is a part of the problem on why people with severe gluten reactions aren’t taken seriously. Cross contamination with gluten alone can be dangerous not only for celiacs. Gluten ataxia causes brain damage and seizures from gluten exposure. I came here to find the answer to this question and sadly there is usually a jerk like Glen in the bunch. It’s why as a person with celiac disease and gluten ataxia it’s difficult to trust people I don’t know with preparing anything I’m going to put in my mouth. Glen please keep your misinformed opinions to yourself.

Why does it mention Krill Oil?

Hmmm... I think there's a mix up of another supplement's information. Source Naturals MegaFolinic doesn't have any krill oil in it at all. I've used this supplement for years, folinic acid is the better form of folic acid, especially for people that have absorption issues, we probably all do today though. :)
