Ray,
Do you know anything about "hypersensitive dopamine autoreceptors"? From my experiences with dopaminergic meds and supplements (they make me feel very tired) and from reading some of Dr. Jay Goldstein's work, I think that I probably have that problem. I wonder how that would fit it with selegiline, DLPA, Norival etc. When I took selegiline, I felt tired from it until many hours later when I got the activating effects. I've tried DLPA and do get a little bit activated on that - particularly when I add it to selegiline or when I consume a little bit of chocolate. So obviously the PEA effect is not a wash out with my malfunctioning autoreceptors. I wonder how the Norival would fit in to all of this. Probably wouldn't have much success with that either. I guess I'll have to try it to know for sure. I'm not even sure what I asking here. Just trying to figure out the full picture of what I'm dealing with I guess. Any insights you might have would be appreciated.
Thanks,
Kara

Sounds like me I guess too. Unfortunately it's even more difficult to get lowish adrenal function treated or even tested...especially ACTH.
I think I'll have to try though.
It's all or nothing with most endos (Cushings, normal, or addisons).
Before taking thyroid hormones by morning cortsol was 310 (about 11 in US)..some say for safety it should be over 12..or preferably 15(multiply by 28 I think from memory for rest of world's units) or more to cope when your metabolism raises with the thyroid meds.After about 3 months on THYROID (Armour) my muscles went strangely really tight..like an athletes...then I developed carpel tunnel like symptoms. I had to add in cortisol to normalise, relax the muscles and stop the pain.
Before adding in the cortisol , my saliva 4 times a day cortisol tests showed pretty low...so low at that midnight (although I couldn't last up that long awake, so took it earlier)..it showed "too low for a reading"..and yes that was hw I felt.
So in me anyway adding in the thyroid meds seemed to cause my already "just coping most of the time" adrenals to crash..or that story seems to cover the symptoms.I guess liquorice would raise ACTH levels? (I need to check this)
I think it raises with
cortisol(by not converting)
and oestrogen(no idea how)
and raises sodium(maybe by helping retain in urine) as well as lowering potassium.
Ray, I'm really very interested in yur approach ..like lowering the antibodies ..as that has been what I have always thought would be the way to go.
You're way ahead of me though and my brain is not functioning very well at present..just wants to go away and do something else and forget it all(fishing sounds good).
I haven't heard of a lot of things you are taking..do you order them from the US..and how did you find out about all of this?
More later, but thanks. It's all very inetersting.

"This idea may be supported by previous findings that complete loss of 1(OH)ase activity by genetic mutation of the 1(OH)ase gene in humans did not cause a reduction in serum 1,25(OH)2D3 levels sufficient to cause severe rickets (5, 6). It is therefore likely that, at least in humans, enzyme(s) other than 1(OH)ase (CYP27B1) are also specifically or nonspecifically responsible for 1,25(OH)2D3 production."

This explains where oestrogen fits in..maybe increases the no of vitD receptors that drives the uptake of calcium into blood(I think it's saying) ..makes sense. I found increasing oestrogen increased my calcium blood levels slightly(doubt if significant though)..still low normal range
"Estrogen and 1,25(OH)2D3 appear to have common activities in the intestine. It has been shown in animal studies[75] that estrogen stimulates the expression of the 1,25(OH)2D3 receptor that drives the calbindin-mediated transport of calcium across the intestinal epithelial cells. It is possible that the negative effect of vitamin D deficiency on the bones of aged patients is enhanced by this lack of estrogen-dependent expression of the 1,25(OH)2D3 receptor."

> Always find it strange that we call vitamin D a vitamin when it's a steroid! I've heard that all the fat soluble 'vitamins' A, D, E, K can be toxic in large doses, but hear different ideas about safe and toxic doses. I did buy a vitamin D cream from biotics but it gives me a splitting headache, so might try some other sources - I definitely couldn't take megadoses of that one! Frequently if there's an enzyme block, taking a precursor of something can cause a build up that further inhibits the enzyme - that happens with omega 6 oils with LA to GLA so perhaps that is my problem with vitamin D?

Got very confused with the Vitamin D articles! All the different formulae and enzymes and routes sent my head in a spin!
I did try my 'biotics' liquid calcitriol again, and got the same headache! Thought about the A and D connection, so tried 12,000 iu of vitamin A from halibut oil, and it feels great! I don't get on with cod liver oil, so this might be a good combination.

That's the trouble with abbreviations - I meant linoleic acid, the omega 6 fatty acid! ALA is the same as lipoic acid, and is also know as thioctic acid. Think you're right, lipoic acid can interfere with T4 to T3 conversion - I take it as lipothiamine in a very small amount and do fine with it - it's essential for energy production and can help with glutathione recycling.>

G6P is needed to make NADPH, the molecule that supplies the energy to recycle glutathione.

Decreasing estrogen isn't exactly helping my dopamine problems. Boosting dopamine can't help either because my system won't allow for it. Not a hopeful picture...

Thanks. My problem is that once the extra dopamine is provided, the hypersensitive dopamine autoreceptors make sure it's taken away quickly. Any attempts to boost it will ultimately fail. (I can take any kind of stimulants and they will put me to sleep.) I would love to go in there and just disable some of those d*mn autoreceptors!!!

Hi Ray,
Did you find that taking glutathione itself helped at all?. I've read it is not absorbed well and it's better to take the NAC and synthesise the glutatione in your body, but without one of the glutathione enzymes(I'm not sure if you mean an enzyme that helps make glut. or one that breaks it down actually).
Just asking as a doc has just given me some glutathione...personally I would prefer to try the NAC..but I'm wondering if you found any benefit from taking glutathione itself?>
> Don't do that well with methionine alone but do well when I combine it with lysine - wonder if it's helping make carnitine? TMG and B12 are both excellent, but the B12 from intensive nutrition works best - other B12s have made me feel awful!
>
I was just reading about methione and lysine combined to make carnitine and was wondering whether to try carnitine or methionine..I have already tried l-lysine ..no effect(tried 2 bottles of) but still have another bottle here I can use of lysine. Of course it could be the tablets..with tyrosine I found I had to take the powder(or powder in capules form Thorne Research) and it had a great effect but the tablets did nothing.

SJW made me anxious..so does niacinamide, and NADH after a while...I haven't worked that out as yet!but any thoughts are most welcome!
Think my cyp3A4 enzyme can be low sometimes, does it work on hydroxylase enzymes too? Interested that it also increases p-glycoprotein, and so helps with glutathione transport across cell membranes (and other conjugates too). For infection, I do well with lactoferrin, medium chain triglycerides and citricidin.....phew, hope you're not overwhelmed or bored!Err overwhelmed..not bored. I've looked at vitamins/minerals for about 20 years..some hormones for about 3 years..but everything else is new, so I'm struggling. Most of the things you are taking are new and interesting ..as well as probably relevant to me.
One thing I could give my feedback on is inflammation and cortisol.
I find that cortisol reduces inflammation. This is different from what some of the writings seem to be saying..or I may have mmisinterpreted?
I think folk use (with me sometimes and only out of desperation) cortisol to reduce inflammtion and antibodies too I think..feels like it.
Prednisone is prescribed (as well as cortisol) to reduce inflammation I think....as in Lupus.Out of all my female cousins, the only one without autoimmune problems (hashimoto/ Lupus) is the one who was on very high dose cortiol for a long period of time (due to a growth?..well something they drained with a shunt.. in her brain). Sorry none of my family seem to not bother with any names of what is actually wrong with them, what they are given to take etc.

Just adding..
I was interested in methionine to form carnitine as I read it helps with mitchondria function..and hence metabolism..which I'm still trying to increase.
I'm on thyroid hormone (THYROID/Armour/T4&T3 etc.)which has helped but my temperature is still way too low ...hence the brain fog, cold etc.There is a bok a guy on the thyroid forum recommended to me. I have it out of the uni lbrary now..and It's the best!..On physiology and I think you'd be interested in it.
You can also read it online for free if you have account at Amazon..that means giving them your credit card details though.
It's called "Review of Medical Physiology" by William F. Ganong 21st edition , 2003. It's updated every 2 years. This is one book I'm definitely going to buy..maybe next edition! For now I'll just renew it from the library.pp303 of above book..you can view online

Hi Kara,I don't think the article was about a straight decrease in estrogen, it was more about the loss of natural rhythm to the menstrual cycle, paticularly in the luteal phase.
The other article talked about tryptophan excess altering the sensitivity of the dopamine receptors - so maybe something that antagonizes dopamine, may make it's receptors overly sensitive, as a compensation? what do you think?
"The greater prolactin response to l-tryptophan infusion in depressed subjects may be the result of an increase in dopamine receptor sensitivity, secondary to reduced dopamine levels."Another abstract made a mention of genetic errors in the dopamine receptor too...
Sorry, don't have any straight answers!

I have been using transdermal glutathione, with good results, but still need the co-factors. Thiodox works well, but eventually I need a break - I'm sure I knock out other anti-oxidants if I take it for a while..

Acetyl-carnitine gives me a splitting headache. I wonder whether the fillers and binders in the tyrosine tablet stop you absorbing it?

> OK I've heard from a few diferent people that oranges, adn especially bitter oranges makes them feel better...what is with bitter oranges?
I've heard that bitter oranges like grapefruits can inhibit liver enzymes (like cyp3a4) and for some people with low glutathione, the preservation of glutathione makes them feel better - the toxins are still there though! It means they only detox as fast as they can cope with - Jeff Bland calls them pathological detoxifiers!
>
> SJW made me anxious..so does niacinamide, and NADH after a while...I haven't worked that out as yet!but any thoughts are most welcome!
SJW boosts cyp3A4 and can deplete glutathione too - I need thiamine, riboflavin, lipoic acid and selenium to go with niacinamide, not sure if that's what you go through?
Not sure if the rest of this was from you or another, let me know if you had another question - hope the answers were of some use!Ray

If taking methionine, it's a good idea to take B12 and folic acid (and maybe betaine too). I find I do better with sublingual b12 and activated folate from thorne called folacal. Folic acid has to be excreted through the bile, then reabsorbed before it can be activated - so it can easily go amiss.
Just found out this weekend how important creatine is for brain energy - I have taken creatine before and not felt that good on it. But at the weekend I found that creatine needs methylation to make it - and that 70% of methylation in the body is to methylate creatine - maybe that's why SAMe is so good for depression? I do feel really good when I take B12, folacal, or betaine, so going to up them! Also it seems that a lot of brain disease is associated with low creatine.

Hi Jan, came across this flow chart for the synthesis of carnitine - it's SAMe that's needed for it's formation, so again it's the whole methylation pathway that needs to work, not just methionine.
http://www.med.unibs.it/~marchesi/carnitine_biosynth.html
came across some articles that say creatine causes depression in some people - I wonder if taking creatine without taking methyl donors can result in a backlog of unactivated creatine, and so have a detrimental effect on brain energy?

>Ray,
I keep hearing and reading lately about serotonergics and their antagonistic effect on dopamine via the receptors. I'm not going to take any tryptophan or 5-htp even for sleep. Maybe my idea to start on Cymbalta isn't such a good one either. Even though it's balanced with NE, maybe I shouldn't be taking anything with serotonin activity at all.
Don't apologize for not having the answer. No one does yet. It doesn't exist.
Thanks as always for your imput,

Maybe not a good idea. I know I was pushing it earlier but now I don't think it's worth the potential dopamine antagonism.-K

> >II'm probably completely off course here, that the problem may be caused by competition for the same enzyme cofactors ...
Dopamine is produced from tyrosine by the action of tyrosine hydroxylase (TH), which uses tetrahydrobiopterin (BH4) as a cofactor. BH4 is also a cofactor for tryptophan and serotonin synthesis, and also for the enzyme nitrous oxide synthetase
or possibly its P5P B6 which I THINK is needed by somehow by tyrosine hydroxylase ?(not sure here) , and low adrenal function meaning it can take up to 21 days(heard that from a doc) to resynthesize enough tyrosine hydroxylase..not sure of this but I think it fits in somewhere with the competiton theory too.
The competiton means making too much of one(say serotonin) will deplete the ability to make the other (say dopamine)..and depletion will eventually cause oversensitivity of the related receptorsI guess.hmm guess I must be low on serotonin looking at this
