Taking Tylenol? The Glutathione Connection
Tylenol (acetaminophen) is one of the most commonly used painkillers, but it comes with side effects. The most concerning effects of using Tylenol are liver damage and glutathione depletion. You might be wondering: how can I prevent liver damage and glutathione depletion? I’ll let you know my favorite strategies and supplements by the end of this article.
What Happens When Glutathione Gets Depleted?
Glutathione is the body’s master antioxidant. Low levels are associated with aging, increased risk of infections (including COVID-19), cancer, neurological problems, diabetes, and more. Low levels of glutathione might make people more susceptible to liver damage from acetaminophen.
What Happens When The Liver Gets Damaged?
The liver is responsible for processing many kinds of chemicals so that our bodies can get rid of them through our bowels. It also regulates blood sugar (via glycogen), produces bile for fat digestion, and When the liver isn’t working optimally, digestive problems and fatigue are common early signs. More serious signs of acetaminophen-induced liver damage include: nausea, vomiting, abdominal pain, confusion, drowsiness, and coma.
Luckily, the liver is very resilient, and even if some degree of liver damage is experienced (either from overdoing it with Tylenol or from something else), the liver usually starts to recover within a couple days of stopping the drug and is fully back to normal within several weeks or months.
How To Prevent & Repair Liver Damage?
Prevention is preferable to repair. The best way to prevent liver damage from acetaminophen is to use it in the recommended doses for the recommended periods of time and not to take too much. However, it is easy to overdose on acetaminophen because it is often found in combination products, so it is important to always read medication labels. It is also very important that acetaminophen not be combined with alcohol.
The liver will repair itself without outside intervention, however it needs building blocks for repair either from supplementation or diet. Important nutrients for optimal liver health and function include vitamin C, vitamin D, B-vitamins, B12, folate, zinc and glutathione. Castor oil packs can also be helpful, as can a liver-focused herbal blend like Liver Detox (Professional Strength).
How To Prevent And Treat Glutathione Depletion
Prevention or treatment of glutathione depletion depends on having a robust network of antioxidants in the body. Glutathione is the “master antioxidant” but there are many other antioxidants which are helpful including: vitamin C, vitamin E, quercetin, beta glucans (eg from medicinal mushrooms), zinc, selenium, and others.
Glutathione can be supplemented directly (it is in my Essential Immune Support formula), or it’s precursor, N-acetylcysteine (NAC) can be supplemented. Supplementing with Vitamin C is also an effective way to increase glutathione levels.
Eating a diet that supports glutathione levels is another option. N-acetylcysteine can be found in protein-rich foods like meat, yogurt and egg yolk and in vegan sources like oatmeal, cruciferous vegetables, garlic, and onion. Other antioxidants are easy to find in brightly colored fruits and vegetables.
Which Dr. Green Mom Supplements Can Support Liver & Glutathione Levels While Taking Tylenol?
For most of my adult patients, taking Essential Immune Support (which contains glutathione, quercetin, vitamin C, zinc, selenium, and more) in addition to daily Super Nutrients provides all the protection that their liver needs to handle routine acetaminophen use.
Pregnant and breastfeeding mothers can bump up their antioxidant protection by adding extra vitamin C and beta glucans found in Mother’s Immunity Support to their Prenatal and Postnatal Daily Nutrients.
For children’s protocols, I’ll often add extra vitamin C and/or zinc to their Super Nutrients gummies to support the antioxidant network if they are taking Tylenol for more than a day or two. This is especially true if the kids have trouble getting in the recommended daily servings of fruits and vegetables.
Tylenol is a safe and effective painkiller to use for short periods of time and in the recommended doses. However, Tylenol does carry the risk of liver damage and glutathione depletion, especially if overused or used alongside alcohol.
Maintaining good levels of antioxidants helps the body process acetaminophen with ease and could possibly reduce side effects. Antioxidants can be found in a number of healthy foods and can also be taken as supplements.
