Excellent!
my mother has alzheimer's, and she needs vit b complex, especially in vit b12, to protect her brain from further damage. I had research on how to take these supplements so that she would fully absorb these vitamins. I make sure that she will take these on empty stomach within 2 hours before or after taking metformin and ascorbic acid supplement for her body to fully absorb vitamin b12. after a few days of taking this life extension brand, I observed that she has gained energy.Excessive B6 levels
I've been taking these for 6 months now and have developed pain in my hands and feet. Just by chance I came across news articles online linking excessive B6 levels to peripheral neuropathy. I bought this product based on the reputation of the brand but it contains 5000+% the recommended level of B6 which is banned in some countries and is linked to peripheral neuropathy. Anyone taking this supplement needs to be aware of this. The condition is not always reversible. Can't understand why this company is not subject to lawsuits.
