I am not familiar with any of those products. I've had issues with toxicity in another KAL product, though, and don't trust their standards. I only use 5-MTHF, not folinic acid.
You may also need other methylation cofactors, like B2, B6, magnesium, trimethylglycine, amino acids, like glycine, and B1 and molybdenum for the transsulfuration pathway.
Products from companies I trust and use are:
Allergy Research or Nutricology NT Factor
Thorne MethylGuard Plus
Thorne Neurochondria
Thorne 5-MTHF
Thorne Pyridoxal-5-phosphate
Thorne Riboflavin-5-phosphate
There are similar products from Seeking Health and Designs for Health that is use if Thorne wasn't available.
I also do injections of high potency B complex and methylB12. There is a Spanish company that makes high quality MB12, the name behind with F as I recall..
