Does biotin effect methylation? I can only find info on it's role in the citric acid cycle. I had complete remission of symptoms for a week on biotin/, but then back to normal . Trying to see if I depleted something else or need more. Thanks.
Hi, David.
Not that I know of. Biotin is one of the nutrients that is depleted in HPU/KPU though, and some of the others that are also depleted in that condition (notably zinc and B6) are needed by the methylation cycle and related pathways.
I'm guessing that you must have been low in biotin, and hence had a backlog of substances that were able to enter the Krebs cycle and give you an energy boost when biotin came up. But over time, this "money in the bank" was used up and then you were again subject to another metabolic limitation that is more fundamental than the biotin deficiency.
Best regards,
Rich
Hi David,
I was going to mention magnesium. My understanding is that increased biotindase activity will place demands on magnesium. If you supplement enough biotin you'll show signs of mg deficiency like twitching etc. I know you know all about magnesium
Susan Costen Owens wrote the Biotin Section in the DAN! book, and she mentions lipoic acid and pantothenic acid in relation to biotin/biotindase. I'm sorry my level of understanding isn't good enough to tell you how this might fit in your case!
Susan runs the yahoo group "trying low oxalates". I think oxalates can replace biotin in certain enzyme functions if you have dysbiosis wich leads to low biotin and/or leaky gut which leads to oxalates circulating. A search for biotin in that group brings up more information.
...I don't know if there's anything there that might give you a clue what to look at next? I was just reading about Biotin myself so thought I'd put my 1 cent in!
Best,
Anne.
Rich, I've been looking around the Krebs cycle, its intermediates, and biotin associated carboxylases looking for a clue. Nothing is jumping out at me as a limiting factor that could be supplemented. Still looking...
The energy-enhancing properties of MCTs are attributed to the fact that they cross the double mitochondrial membrane very rapidly, and do not require the presence of carnitine, as do LCTs (Fig. 2). The result is an excess of acetyl-coA, which then follows various metabolic pathways, both in the mitochondria (Krebs Cycle) and in the cytosol, resulting in the production of ketones. Scientists attribute the increased energy from consumption of MCTs to the rapid formation of ketone bodies. MCTs are thus a good choice for anyone who has increased energy needs, as following major surgery, during normal or stunted growth, to enhance athletic performance, and to counteract the decreased energy production that results from aging.

I take high doses of biotin and have oxalate problems. It helps alot with my fatigue and with candida problems.
WHen a person has oxalate problems , there is often what is called a dumping process whereby the oxalates come out of storage and make a person feel worse. I have found this with taking biotin. So maybe you are in a stall period because you have done nothing to address lowering you oxalate total load/. There is a low oxalate diet one needs to follow and depending on the person will take time to see permanent results.

Hi Nancy, thank you so much! It was one of your posts that got me to look at and try biotin. That's when I discovered that biotin, and many other nutrients, are depleted by clonazepam (Klonopin) which I have been on for several years. I'm now trying to taper and hopefully recover from the anti-nutrient damage it has caused.

Hi David,
I hadn't heard that clonazepam depletes biotin -- I've read it depletes b12 and coQ10 however -- but was wondering if you have a link or links to the 'many other nutrients' that it depletes?
I've tried to taper off (using the Ashton method) and got close, but then my medicaid doc switched me back(!). Long story, but eventually want to get off of it as well. I'm sure you know that it's the only benzo that has anemia and low white blood cell count as "side effects".
THANKS,
Dan
Wondering how much you guys think clonazepam has to do with our symptoms? In my case, I think it's affected me a great deal. Since I've been on it, (at least 2 1/2 years, though I'm not sure), my mental PEM has increased to the point where I can no longer read books, and even short durations on the computer are detrimental. Yet, it snuck up on me and I never attributed the symptoms to the benzo because it was "helping". Plus, "it's such a small dose".
In my case I'm prepared to say it has everything to do with my condition. Still trying to taper by cutting, water titration didn't work for me. I'm at 1/8 of a .5 mg tablet (62 micrograms or .0625 mg). It's not an accurate cut at that size of course, I may get a compounding pharmacy to make some lower dosages.
Hi Dan,
The book I quoted previously: "Barbiturates deplete biotin, folic acid, and vitamins D and K. Benzodiazepines deplete these nutrients, plus calcium and melatonin."
Clonazepam is an anticonvulsant, there is quite a bit of data on anticonvulsant nutrient depletion. Here are a couple:
Effect of long-term treatment with antiepileptic drugs on the vitamin status.
Vitamin status in patients on chronic anticonvulsant therapy.
I haven't seen any mention of Coenzyme Q10 depletion in my research. Biotin is the most depleted from what I've seen.

Read these 2 quotes somewhere, (I think the first is Dr. Ashton):
"For most long term users of benzodiazepines, the risks of usage outweigh the benefits. In most people the benefits wear off. Although a person taking a tranquillizer or sleeping tablet regularly may believe they still derive benefit, all the medication is really doing is suppressing withdrawal symptoms."
"Withdrawal either occurs through the development of tolerance without an increase in dose, or through a decrease in dosage below your "tolerance point". Your tolerance point is the dose point below which the functioning of your receptors becomes impaired due to a deficiency in stimulation from the drug. Your tolerance point may be lower than your actual dosage, such that you can sometimes cut your dose by some amount without experiencing withdrawal symptoms. However, this does not mean that you will not experience withdrawal symptoms by cutting the dose further."
In my case, I was taking .5mg every night. According to the second quote, this would create "development of tolerance without an increase in dose". I definitely think this was going on. I've been tapering with Fred's advice. I'm down to 3/4 of a .5mg pill after 30 days, but I'm taking divided doses throughout the day and I'm feeling a little better. I think, (hope!), getting off clonazepam is going to help. Going to take awhile though.
David -- I'm not sure if clonazepam (klonopin) is officially considered an anticonvulsant, but that might be splitting hairs. I totally understand where you're coming from (the way it helps with fasciculations, etc.,) but just haven't seen it in lists of anticonvulsant drugs.
Have you? That would be important to know for sure.
