Has anyone
@tanedout tried high dose B1, I think
@Helen has suggested it in the past. Sorry for the wall of text below, just found all this, and seems like some good connections with
electrolyte protocol and ACCUTANE, FIN, NADPH, Sulforaphane THIAMINE, copying relevant posts from this user on acne.org: tryingtohelp2014
Retinoic acid = decreased Transketolase (thiamine deficiency)
Accutane inhibits hippocampal neurogenesis by using up the NADPH reducing cofactor... Thiamine
NADPH needed as a CYP26A cofactor for retinoic acid detoxification.
NADPH (B1) and FAD (B2) cofactors should be promoted.
===
Vitamin K2 has nothing to do with the activation of CYP26 or any other CYP enzyme needed specifically for all trans retinoic acid detoxification. its not a co-factor.
However Thiamine is a co-factor to produce K2 (menaquinones ) so anything related to a K2 deficiency could be just the missing cofactor.
Thiamine is a cofactor for NADPH which is needed for CYP26A

NADPH oxidase and thyroid function
An interesting aspect of the NADPH oxidase system is that it plays a major role in thyroid function. Thyroid hormone synthesis is dependent on NADPH in both the thyroid and the liver. In the thyroid, two separate NADPH oxidase systems are used to generate free radicals, particularly hydrogen peroxide(H2O2), that are used to build the thyroid hormones T4 and T3(5, 6). In the liver, the less active T4 is converted in to T3 by an NADPH-dependent enzyme, 5'-deiodinase(7, 8) that utilizes reduced glutathione to make this conversion. Again, the solution to problems like this are much more complex than just throwing thiamine at them. T4 and T3 help regulate the conversion of riboflavin to FAD(9, 10, 11) which participates in many of the thiamine dependent enzymes as a cofactor and both FAD and selenium are needed for the glutathione cycle to work properly.
NADPH provides the reducing equivalents for biosynthetic reactions and the oxidation-reduction involved in protecting against the toxicity of reactive oxygen species (ROS), allowing the regeneration of glutathione (GSH).[3]NADPH is also used for anabolic pathways, such as lipid synthesis, cholesterol synthesis, and fatty acid chain elongation.
The NADPH system is also responsible for generating free radicals in immune cells. These radicals are used to destroy pathogens in a process termed the respiratory burst.[4] It is the source of reducing equivalents for cytochrome P450 hydroxylation of aromatic compounds, steroids, alcohols, and drugs.

NADPH ACCUTANE FINASTERIDE connection.
we need to increase NADPH.
60% of our NADPH is made through the Thiamine dependant the pentose pathway.
Red blood cell transketolase activity is reduced in deficiency of thiamine (vitamin B1), and may be used in the diagnosis of Wernicke's encephalopathy and other B1-deficiency syndromes if the diagnosis is in doubt.[8] Apart from the baseline enzyme activity (which may be normal even in deficiency states), acceleration of enzyme activity after the addition of thiamine pyrophosphate may be diagnostic of thiamine deficiency (0-15% normal, 15-25% deficiency, >25% severe deficiency).[9]
#1: Direct 5-Alpha Reductase Inhibition
Competitive Inhibition
5-alpha reductase doesn’t just arrive out of nowhere. In order for this enzyme to form and mediate the whole DHT conversion process, it needs the help of a coenzyme known as nicotinamide adenine dinucleotide phosphate… or in other words, NADPH.
5-alpha reductase needs NADPH to convert free testosterone into DHT. So an effective way to stop the formation of 5-alpha reductase (and reducing DHT) is to…
Compete with the coenzyme NADPH, or Block NADPH
These are two mechanisms of direct 5-alpha reductase inhibition – or for the lay person – reducing 5-alpha reductase by stopping it from forming. And while it’s still up for debate, the hair loss drugs Finasteride and Dutasteride – two 5-alpha reductase inhibitors – appear to work in this way.
Mechanism 1: Compete With NADPH
Some research shows that Finasteride competes with the coenzyme NADPH. Finasteride’s molecules take the place of NADPH in a cell, and in NADPH’s absence, 5-alpha reductase cannot form. The end-result? Less DHT. And another 5-alpha reductase inhibiting drug – Dutasteride – seems to do the same thing (using a slightly different molecule).
Mechanism 2: Block NADPH (Or Bind To NADPH And Change Its Structure)
There’s also research showing that instead of competing with NADPH, Finasteride may instead bind to NADPH and change NADPH’s structure into a different coenzyme – one that doesn’t support the formation of 5-alpha reductase. The bottom line: free testosterone can no longer convert into DHT.
Interestingly, zinc may also reduce 5-alpha reductase and through a similar manner. Evidence suggests that zinc reduces NADPH production, thereby decreasing 5-alpha reductase activity. The less enzyme activity, the less DHT.

"I’m assuming you mean large amounts of Thiamine ( B1 ) as we’ve all taken this as part of our B complex supplements with very little effect yeah?
I’ve even stepped it up a notch by taking the “active” form of B’s more recently but again nothing noticeable in the way I feel.
How much Thiamine do we need to be taking to notice anything?"
up to 1500mg has been discussed. starting at a lower dose...and moving up. allthiamine cream is transdermal and gets around the whole digestive tract. it also crosses the blood brain barrier. this has been used successfully in autistic children. people have used both b complex and thiamine by itself read up on Dr Lonsdale. he is the expert in B1.
I think its a transporter problem..and you really need to saturate the serum. some things you have to watch with thiamine... magnesium gets used up and folic acid.

High dose Thiamine has been recommended as a treatment.
Thiamine is needed for NADPH (the first step is isotretinoin catabolism) 60% comes from the pentose pathway
Thiamine is needed to produce stomach acid (think SIBO , bacterial imbalance, Chrons etc)
Thiamine is needed for collagen formation
Thiamine is needed to produce ATP (think ER dysfunction/ROS/detoxification)
Thiamine is needed for estrogen clearance in the liver (along with riboflavin) estrogen dominance, low T LH FSH etc.
Thiamine is needed to recycle GSH.
Thiamine is needed in steroid formation
Thiamine deficiency is noted in low ceruloplasmin results.
The test needed for this is an erythrocyte transketolase test. normal blood tests are not accurate.
ALLTHIAMINE is preferred. i have been using the topical. I tested high for estrogen last summer. I believe i had an estrogen-induced form of cholestasis. Ive had high bilirubin for 20 years since accutane. In the past 2 weeks, the whites of my eys have been totally clear, and ill be getting a confirming blood test. Taurine did this for a few days..but it was hit and miss. We could have downregulated receptors, and the full effect could take a while to fix.
Magnesium and B1 should be taken together
Could accutane be the trigger like Gardisal?
something very very interesting here, and it related to P53 and FOX01

p53: key conductor of all anti-acne therapies
This review based on translational research predicts that the transcription factor p53 is the key effector of all anti-acne therapies. All-trans retinoic acid (ATRA) and isotretinoin (13-cis retinoic acid) enhance p53 expression. Tetracyclines and macrolides via inhibiting p450 enzymes attenuate ATRA degradation, thereby increase p53. Benzoyl peroxide and hydrogen peroxide elicit oxidative stress, which upregulates p53. Azelaic acid leads to mitochondrial damage associated with increased release of reactive oxygen species inducing p53. p53 inhibits the expression of androgen receptor and IGF-1 receptor, and induces the expression of IGF binding protein 3. p53 induces FoxO1, FoxO3, p21 and sestrin 1, sestrin 2, and tumour necrosis factor-related apoptosis-inducing ligand (TRAIL), the key inducer of isotretinoin-mediated sebocyte apoptosis explaining isotretinoin’s sebum-suppressive effect. Anti-androgens attenuate the expression of miRNA-125b, a key negative regulator of p53. It can thus be concluded that all anti-acne therapies have a common mode of action, i.e., upregulation of the guardian of the genome p53. Immortalized p53-inactivated sebocyte cultures are unfortunate models for studying acne pathogenesis and treatment.
THIAMINE......
In contrast, an increased number of thiamine transporters are observed in cells that overexpress thiamine transport genes (mTHTR-1) and in cells that are exposed to conditions that induce DNA damage or p53 activation.56 Thiamine diphosphate inhibits p53 binding, and thiamine inhibits intracellular p53 activity.57 Thiamine treatment significantly decreases p53 expression in the cultured retinal neurons from diabetic rats.58 These observations suggest that the pro-apoptotic transcription factor p53 is activated by cellular damage in HIV infection and that thiamine ameliorates these effects.

i have gilberts syndrome as well. well, just high bilirubin. i dont believe i ever had high bilirubin before taking accutane though. so its a chicken and the egg question.
if you have gilberts , you conjugate at 30% the normal rate. the same UGT enzyme that conjugates bilirubin is also responsible for the glucuronidation of accutane.
PHASE 2 ... read up on NRF2
every single person who has ever reported feeling better has unknowingly promoted the NRF2 response.
either from water fasting, TUDCA, CBD oil, etc etc etc.
