Detoxification is important for everyone, as we discussed last week in the shocking list of things that add toxins to modern life. Unfortunately, detox is also easy to get wrong - even for practitioners. So here are some of the basic foundations to good, effective, ongoing detoxification.
You Detoxify in Many Different Ways
Sweat, breath, urine, feces, even menstrual blood, and everything your body excretes are potential removers of toxins, which is great news for us. The bad news is that it isn't as easy as moving the toxin into the bladder and then the next time you go to the bathroom, you're done. Detoxification happens in three phases, all of which involve chemical reactions. We will go into these phases in more depth next episode, because this is a lot of why detox can feel bad.
The Three Phases of Detoxification:
Phase I: The toxin undergoes one or more chemical reactions, converting it to some kind of intermediary molecule that will bond easily with our major toxin conjugators. This often makes it far more toxic and dangerous to your body. This step also tends to release a lot of free radicals. Phase I detox happens largely because of the cytochrome P450 family of enzymes, mostly in the liver.
Phase II - The newer, often more active toxin floats around in your bloodstream, wreaking havoc until it can go through one of six conjugation reactions, which involve bonding it to something else that will ultimately help it be carried out of your system. These six reactions include sulphation, glucuronidation, glutathione conjugation, methylation, acetylation, and glycination. These pathways need specific resources, like glutathione, sulphur, and methyl groups, and there are several gene SNPs that interfere with these resources.
Phase III - This is the step that carries toxins into waste tissues through transport proteins and antiporters. These help to carry toxins through the blood-brain barrier out of the central nervous system, out of cells, and into the gut lumen, kidneys, or sweat. This isn't like a filter; your body must actually expend energy to push these toxins out.
You Can't Detox if You Don't Eliminate - Detox Basics!
Obviously, if you're pushing toxins into your gut, your sweat, or your urine, then you have to be eliminating those substances for the detox to work. You can't detox if you only poop once per week - you have to fix the bowel issue before toxins will be able to move out of your body. Also, if you try to "do a detox" while your bowels aren't moving, then prepare to live in a world of misery. Likewise, if you don't sweat easily, then sweating isn't an effective method of detox for you. Interestingly, non-sweaters who work on their toxic burden often see an increase in their ability to sweat over time.
Also, I'm hoping it goes without saying, but your body needs a lot of water to detoxify. More, even, than the standard 64 oz or eight 8 oz glasses suggested. Coffee doesn't count toward your water total, and if you're trying to detoxify, lots of water with a good source of trace minerals like Himalayan salt or trace mineral concentrates is key.
The Most Important Thing is Not Adding More Toxins
This may be even more basic than "detox basics," but it can be easy to forget. The less toxin exposure you have, the more able your body is to deal with what comes in, so doing a quick clean up of the toxins in your house and body is the best way to start any kind of detoxification ambitions. Last week, we touched on some of them, but the highlights include:
Voluntary (cosmetic) implants like breast, cheekbones, calf, pec, and gluteal implants
Unnecessary prescriptions and supplements (work with your doctor on this one)
Air fresheners, artificial fragrances, and odor removers
Stain guards or waterproofing chemicals for fabric
Phthalates and parabens in personal care
Artificial colors, fragrances, emulsifiers, and preservatives in food
Pesticides and herbicides around your home and in your food
Plastic food storage or food preparation containers
Aluminum or non-stick cookware
You Need Nutrients to Detoxify
Detoxification takes a lot of energy and resources from your body. You need antioxidants to help deal with the free radicals released in toxin metabolism, and also free radicals created by damage that the toxins are doing to your tissues. This can include vitamins like C, A, E, and D, and other compounds from fresh fruits, veggies, and herbs. Also, you need the raw materials for the six types of conjugation reactions, including methyl groups, glutathione, sulphur, glycine, and the vitamins and minerals involved in cellular energy.
This means, at the very least, a great-quality multivitamin and a clean, nutrient-dense diet, but it could also mean specific support if you have something like an MTHFR polymorphism, in which you would need extra active B vitamins and methyl groups as well as extra glutathione to make up for any production deficiencies. This is part of why it's important to work with a practitioner when you're detoxifying, so that they can help you identify areas in your diet, lifestyle, and genetics that may need extra support.
What Does it Mean to Push Detox?
I want to say a bit about pre-packaged detox kits or products, and the trouble they can cause if you aren't ready for them. Most detoxification products PUSH detoxification, rather than supporting detoxification. They include herbs and nutrients that upregulate cytochrome P450 enzymes, meaning that you go through phase I detox extra quickly and get all these intermediary toxins and free radicals. If you don't have phase II and phase III nutrients and substances in line and ready, then it's all going to suck. We will dive into this problem in the next episode.
