Five Natural Detoxifiers for Everyday Life
Astaxanthin is one of the most potent antioxidants found in nature. A xanthophyll carotenoid with blood-red pigment, astaxanthin has been widely explored for its antioxidant, anti-inflammatory and immune-enhancing properties, along with beneficial effects on DNA repair.
Astaxanthin supplementation for four weeks was found to increase blood levels of the antioxidant glutathione in active young men. In an animal study, this marine biocompound emerged as a critical agent in protecting the brain against neuroinflammation and oxidative stress induced by environmental tobacco smoke.
Heavy metal toxicity poses serious human health risks. Exposure to pollutants, xenobiotics and heavy metals such as mercury and lead can affect the levels and activities of antioxidants and enzymes in the body. The algae chlorella offers numerous nutritional benefits and helps enhance the elimination of these heavy metals.
It reduced the half-life of chlordecone, an organochlorine insecticide, from 40 to 19 days and contributed to the removal of heavy metals in patients with long-term dental titanium implants and amalgam (mercury) fillings.
In young Korean adults, chlorella supplementation detoxified carcinogenic heterocyclic amines (HCAs). A 2015 study also showed that it helped women detoxify cancer-causing polycyclic aromatic hydrocarbons (PAHs), a class of chemicals produced when coal, gas, wood, garbage or tobacco is burned, through epigenetic modulation.
Garlic has a long history of medicinal use, as well as a culinary history as a staple in cooking. Its major component allicin, besides showing remarkable antiviral, antifungal and antibacterial activity, is thought to play a role in its antioxidant and detoxification capabilities.
Garlic appeared safer clinically and as effective as the drug d-penicillamine in treating mild to moderate lead poisoning. Clinical improvement was significant in a number of symptoms such as irritability, headache, decreased deep tendon reflex and mean systolic blood pressure after treatment with garlic but not drug therapy, wrote the researchers.
Along with onion, garlic also exhibited anticancer properties partly due to its ability to induce phase II detoxification enzymes. A separate study suggested that this effect may be partly due to organosulfur compounds in garlic, such as sodium 2-propenyl thiosulfate (2PTS).
4. Broccoli Sprouts
Broccoli sprouts, or baby broccoli plants, are cruciferous vegetables that may aid in natural detoxification. Broccoli, along with its phytochemical sulforaphane, may activate enzymes that may protect against toxicity from PAHs. Broccoli sprout extract may protect the liver from different types of xenobiotic substances by inducing detoxification enzymes and glutathione synthesis.
A small amount of broccoli sprouts may also help protect against chemical carcinogens. “[S]mall quantities of crucifer sprouts may protect against the risk of cancer as effectively as much larger quantities of mature vegetables of the same variety,” wrote the researchers of a 1997 study.
In animal studies, broccoli sprouts also attenuated oxidative stress from alcohol consumption. Thus they may protect the liver by increasing antioxidant capacity and downregulating associated stress.
5. Green Tea
Green tea offers not just a soothing beverage, but also acts as a shield from some everyday toxins. According to animal studies, green tea and matcha green tea can reduce the adverse effects of lead as well as lower gastrointestinal tract absorption of common offenders such as polychlorinated biphenyls (PCBs), polychlorinated dibenzofurans (PCDFs) and dioxins.
In the aging brain of animal models, catechins from green tea also protected against declining glutathione peroxidase levels and the ensuing age-related oxidative damage.
