By Michael A. Smith, MDAlmost 70,000 industrial chemicals can be found in our environment these days, with 1,000 new synthetic chemicals introduced each year.1
Mind you, only a fraction of these new chemicals have been tested for safety in humans. Doesn't that make you feel warm and fuzzy inside?
So what’s the best way to protect yourself against this toxic deluge? The short answer is to detox. However, before you start shopping around for detox products, you might want to look at the detoxifying abilities that your own body offers.
If you weren’t already aware, the human body actually has an incredible detox system built right into it … and it’s called your liver.
The Liver is a Detox MachineYour liver is responsible for metabolizing and detoxifying the natural or synthetic chemicals that enter your system. The liver actually works in two phases to detox your body:
- Phase One – The liver uses oxygen and enzymes to burn toxins. This process is called oxidation, and it makes the toxins more soluble in water. Making them more water soluble means they can be more easily excreted from your body by your kidneys or liver. Since most environmental toxins are fat-soluble to start with, they’re difficult or impossible to eliminate without your liver’s help.
- Phase Two – This is called conjugation. In this phase, the oxidized chemicals from phase 1 are combined or “conjugated” with sulfur, specific amino acids, or organic acids, and then passed out of your body.
Over time, your liver can become damaged from the detox process and start to dysfunction. When this happens, the toxins start to take over ... and you can probably imagine what happens from there.
This is why the first step in any detox program should be designed to support your own liver’s detox phases and to optimize its overall function. So let’s take a look at two key nutrients that can do just that.
Milk Thistle – a Phytonutrient for Liver SupportMilk thistle has been used for over 2,000 years as a life-supporting nutrient. It’s even been approved by the German Commission E Monographs for inflammatory liver conditions, helping to establish it as a respected, safe, and effective botanical.
Milk thistle is rich in polyphenols, which are plant-based antioxidants. There are two broad categories of polyphenols — silymarin and silybinin. These powerful antioxidants offer protection against food toxins, alcohols, and environmental toxins by ultimately supporting liver function.
Silymarin, for instance, has been shown to significantly reduce liver-related mortality in patients with alcoholic liver damage.2,3 Also, silymarin extracts have successfully improved liver function blood tests and produced improvements in general well-being in patients with viral hepatitis.4
There are many different sub-types of silymarin and silybinin.5,6 Here are the primary ones to look out for in a high-quality milk thistle product:
- Silybin A
- Silybin B
- Isosilybin A
- Isosilybin B
SAMe Boosts your Liver’s Antioxidant ArsenalEnvironmental toxins increase oxidative stress and end up depleting your liver of its natural antioxidants, like glutathione. Without glutathione, your liver can actually become damaged during detoxification, especially during phase one.
S-adenosylmethionine, better known as SAMe, is a precursor to glutathione. Supplementing with SAMe helps restore glutathione levels and allows your liver to protect itself from the onslaught of free radicals produced by toxins. For this reason, many liver experts are recommending SAMe these days as an area of increased study for humans with liver disease.7
Aside from optimizing liver function, the US Department of Health and Human Services also lists balanced mood and joint support as additional benefits that SAMe offers.
So how much SAMe should you take? Everyone is different, but we generally suggest supplementing with about 800 to 1200 mg per day.
Detox Begins & Ends with a Healthy LiverThe first step in ANY detox program should be to enhance your own “built-in” detox system, the liver. For this reason, milk thistle and SAMe are two great nutrients worth considering.
If you want information on the best “external” detox choices, we’ll be covering that topic soon here on the blog. Please stay tuned.
