Your product is great
Kitties with CKD benefit greatly from B12 supplementation in its natural form (Methylcobalamin) as it reduces inflammation
If you are very B12 deficient you will notice an increase in energy and a reduction in symptoms of tingling, numbness, or twitching/zaps within 24 hours
Doctors need to diagnose a Vitamin B12 deficiency or a condition that needs it
Tell your clinician about any medicines that may affect vitamin B12 or folate testing, such as antibiotics, methotrexate, pyrimethamine, colchicine, para-aminosalicylic acid, or heavy alcohol use
The sensation you felt after drinking the wine may, or may not, have had anything to do with the B12 but personally I have a tiny (snifter) glass of fortified wine every day without any adverse effect and I'm still " clivealive " and nearly 77 years old Don't forget to get your Folate level checked, Thank you clivealive
