Thanks.

I ordered the Kirkland 5mg from CostCo. They had a $3.00 non-member surcharge, but since they do not have one where I live it was not worth $55 to join.

I was just surprised to see Puritan Pride say to take it with food. Empty stomach it will be .

I am thinking 5mg/day. Your 5mg/day maxed out your lab. What level should I be trying to obtain for PN and homocysteine control? Typically, what is the dosage used by most folks?

Your comments have been very helpful. Thank you very much!

Next is to look at P5P.
