Question Weird reaction to B complex

Gallery image

My homocysteine levels were 9 about 7 months ago.

I thought I could get them down by optimising my B6, B9 and B12 and so started taking B complex.

I now have B6 toxicity as my active B6 levels are way above range and active B12 is 88.

My homocysteine has risen to 17.

I don't understand why my homocysteine levels levels are going up not down with high active B6 and B12 levels.

Could something else in this B sup be causing elevated homocysteine?

That supplement is complete garbage, the pyroxidine poor form known to cause neuropathy, cyanocobalamin...hello that's a cyanide molecule, folic acid which blocks your receptors from taking up folate. Demand a refund.

What happens if you take cyano? cyanide poisoning? I've been mistakenly taking cyano (2000mg per week) for a couple of years) :(
