RobE - this is in regard to your question regarding nutrients being able to bolster detoxification in the liver.
Detoxification in the liver is broadly categorized into "Phase 1", and "Phase 2" pathways. Both these pathways utilize enzymes to neutralize undesirable compounds. Phase I detox employs a group of enzymes (about 50-100), collectively referred to as "Cytochrome P450". Isozyme P450 2D6 that Phase Dancer referred to is part of this system. P450 enzymes are sometimes able to directly neutralize the toxin (as is the case with caffeine), and other times they must convert the substance to other chemically reactive forms which are then metabolized by Phase II detox pathways.
Despite these pathways being very effective, a problem arises when we bombard our liver with toxins, whether they be MDMA, alcohol or various other drugs. Phase I detox in particular, generates large amounts of free radicals - molecules which have the potential to inflict cellular damage. If your Phase II systems aren't working effectively, these toxic intermediates persist for much longer, and cause more damage.
As Phase Dancer said, the efficiency of the detoxification pathways, such as in the 2D6 instance, can be dependent on genetic factors. There are two other crucial factors however, and they are:
1. The person's level of chemical exposure.
2. The person's nutritional status.
The importance of nutritional status can be exhibited by the following example.
The most important liver antioxidant enzyme for detoxifying Phase I metabolites is "glutathione peroxidase", which is made from the amino acids cysteine, glutamic acid and glycine. Phase II detox is heavily dependent on glutathione, so if your toxic load (i.e. drugs) is very high, it is depleted radidly, and Phase II grinds to a halt. Now, glutatione is actually dependent on the trace mineral, selenium - which is why you find selenium in antioxidant formulas. No selenium = no glutathione = problems.
As Phase Dancer pointed out, the problem is that everybody varies. Some of us have very effective Phase I, and not so effective Phase II - others, it's the other way around. But the one thing we can control is our nutrient intake - and this is vital, if we wish to remain in good health. While the jury is still out on neurotoxicity (at least in regard to how it occurs), we can safely consider MDXX as hepatotoxic - i.e. not good for your liver. When your consider all the other crap you might ingest on an average night (alcohol, cigarettes, speed, and all the other dubious chemicals in pills) looking after yourself between rolls becomes paramount.
So what does our liver love? Well, the key nutrients for Phase I detox are:
* Copper
* Magnesium (also good for mad jaw disease, as we know)
* Zinc
* Vitamin C
These are all involved in Phase I detox at different levels, some in enzyme synthesis, others as direct antioxidants. Certain other substances are highly effective in inducing effective Phase I detox. These include:
* Indole-3-carbinol - This is found in broccoli and cabbage, and is a powerful anti-cancer compound - (eat your greens!)
* Limonene - A phytochemical found in oranges and other citrus, that induces both Phase I and Phase II detox.
Phase II -
Phase II employs a biochemical process called "conjugation", where nasty metabolites are neutralized. However - and this is important - certain substances inhibit this process.
In grapefruit, there is a compound called "naringenin" which decreases your cytochrome P450 activity by up to 30%(!) This is a problem, especially as lots of people advocate drinking grapefruit juice just before rolling... now, it won't kill you, but it has the potential to significantly increase the toxicity of any novel chemical such as MDMA. But - you can actually increase the efficiency of the Phase II pathway also, by taking certain nutrients:
* Lipotropic Factors - This is a collective term for Vitamins B6 and B12, folic acid, choline, betaine and methionine. They can be supplemented individually, or obtained as a complex from Naturopaths etc. Together, they increase levels of glutathione, and another compound called
S-adenosylmethionine, or SAM-e for short.
The other major liver detoxifier/protector is a herb called Milk Thistle. This contains a complex of flavonoid compounds referred to as "silymarin", which exhibit some of the most powerful pro-liver effects known. Taken supplementally (as a standardized herbal extract), both before and after rolling, can dramatically reduce the damage to your liver. It actually helps to prevent the depletion of glutathione, and appears to form a protective "shield" around liver cells, allowing them to escape free radical damage.
Anyway, sorry this is a bit longwinded. Hope this is of some help to you - just remember, anything you can do to offset the damage caused by pills, and other drugs, your body will thank you for. To me, this is what "harm-minimisation means".
