interesting note about the B50 complex. I recall you mentioning before but i don't recall the backup detail (?) That potentially harmful?
AMPK sensor: Friend or foe?
@BioEclectic
Starting point: Too much of a good thing can become counterproductive (cancer).
BioEclectic, a forum user on bioenergetic.com, recently asked me why it was not appropriate to regularly take a complex Vitamin B50 supplement. OK if it's 2x/week or these are the RDA if taken regularly, knowing that we will then have chosen a co-enzymated form (with cofactors), without yuck ingredients. (…)
Short answer:
AMPK functions as an energy sensor in our cells. This sensor plays a key role in the balance between anabolic and catabolic programs for cellular homeostasis in response to metabolic stress.
In the case of a tumor, the cancer cell attempts to slow down oxidative metabolism and works to divert the supply of glucose for its own benefit in order to grow. The cancer cell will therefore try to down-regulate the influence of AMPK, which acts a little too much like a traffic agent to supply the different organs, instead of promoting the flow of fuel to the advantage of his own needs.
So, what the link with cancer?
Taking high dose of thiamin (B1) or pyridoxine PLP (B6) – they are just 2 examples of antioxidant – they act to moderate the AMPK sensor, to dampen the effects. Right in cure or if the dose turns round RDA but not for prolonged use.
Reactive oxygen species (ROS) are continuously produced as a by-product of mitochondrial metabolism and eliminated via antioxidant systems.
Cancer cells try to moderate / neutralize anti-stress.

Cancer cells are usual, at a certain age, and have to be considered “normal” if the size does not exceed a €2 coin…
