I doubt methylation people look at it correctly. I think it is just since NADPH is lacking. MTHFR does not work, also folic into tetrafolate does not work. And MOREVER they are going backwards.
By giving methylfolate, some people are losing their gums , since there is no mutation really . There is lack of NADPH. And without NADHP you cant keep going further into thyroid, or l dopa , all those enzymes produce superoxide. and H2O2. This is why people taking methylfolate have all these inflammations and they call it detox)).
There isnt supposed to be a methylfolate without NADPH. Bypassing it. Creates oxidative stress. Freddd encountered it by almost losing all his teeth))
SO I think methylation enzymes just go backwards, basically MTHF goes backwards, DHFR goes backwards. This is all to produce NADPH
This is why they says that methylfolate recycles bh4, or folate recycles bh4. Since tetrafolate or methylfolate going backwards will produce NADPH. Then this NADPH will recycle glutathione which will recycle vitamin C which will recycle bh4.
And actually if you take folic acid, that will stop backward movement of Dhfr and people feel bad.
Lack of NADPH is what causes hairloss and methyl block.
vitamin C and NADPH is what turns cholesterol into bile acids. So this is the same. Most things really are about keeping vitamin C in active form along with vitamin E.
aging is the same. hairloss is the same. Vitamin C is what activates vasopressin. SO without active recycled C , you are screwed. since you will be dehydrated.
NO active C , no vasopressin, no active C - no bh4. You are offically dehydrated and eNOS making superoxide, Double whammy , how can hair survive this.
Basically a pool of free NADPH is what allows the body to run faster . LIttle pool of NADPH< boom slow down and sit. By passing it with thyroids, methylfolates, etc is weird if you ask me. May be that is why RIck Van K, died a couple of years ago. Who was into this methylation thing. Suddenly just died. I guess from a heart attack. And we know that heart wont handle oxidative stress. if you lose your gums like that. You can really lose heart tissue the same way.
SO we need to be careful about all this active stuff. IMO
