Glutathione: Doctors Say You Cannot Ignore Its Anti-aging Benefits

Learn why doctors recommend we include glutathione in our diet to preserve our youthful body and skin.
What You Need To Know About Glutathione Supplements


Why Doctors Love Glutathione 


The molecule we’re talking about here is no snake oil… it’s an important antioxidant that you’ve probably barely heard of. It’s glutathione, a substance that is naturally produced in the liver and found in meat, fruits, and veggies. 

Glutathione (pronounced “gloota-thigh-own”) might be a mouthful to say, but it’s becoming a household name nonetheless. It is known as the "mother of all antioxidants" and the "great protector," and it’s not hard to see why.

It is a protein comprised of 3 amino acids—glutamine, cysteine, and glycine—made naturally in the liver and used in every cell in the body. 

However, aside from collagen supplements, many doctors are recommending to also take glutathione supplements  as it is one of the most important molecules your body needs to stay healthy and youthful.


What Does Glutathione Do?


As an antioxidant, glutathione protects cells against the oxidative stress that damages cell membrane proteins. Glutathione not only fights free radicals (those evil organic molecules that are responsible for aging, tissue damage, and diseases) but also recycles used anti-oxidants in the body. 

It is critical for immune function and controlling inflammation. It is the master detoxifier and the body’s main antioxidant, protecting our cells and making our energy metabolism run well.

The caveat is that glutathione gets depleted with age, poor diet, pollution, toxins, infections, and radiation, among other lifestyle factors. 

Top British medical journal, the Lancet, found the highest glutathione levels exist in healthy young people, lower levels in healthy elderly, and lowest in sick elderly.

Glutathione deficiency can lead to a multitude of diseases and health conditions (Main PA, et al. Nutr Metab(Lond). 2012; 9(1):35

  • Premature aging, Alzheimer's, and Parkinson's disease
  • Chronic infection, auto-immune disease, fatigue
  • Cancer, diabetes, asthma
  • Heart disease
  • Liver disease, kidney problems
  • Skin aging, wrinkles, grey hair


How Glutathione Works


According to Dr. Hyman MD, the secret of its power is the sulfur (SH) chemical groups it contains. Sulfur is a sticky, smelly molecule. It acts like fly paper and all the bad things in the body stick onto it, including free radicals and toxins like mercury and other heavy metals.

What Is Glutathione

As a detoxifier, It binds metals and other toxins and transforms them into compounds that can be excreted in bile or urine. Once bound, these toxins become water-soluble and can be transported out of cells. 

Normally glutathione is recycled in the body — except when the toxic load becomes too great due to aging and overexposure to chemicals, pollutants and sun damage.

However, the binding of toxins to glutathione creates a demand on the body to make new glutathione. Deficiency results when a tissue or system cannot keep pace with the demand

But there’s good news! Glutathione is produced naturally in your body and the liver harbors the body's largest supply!


Glutathione Benefits for Skin and Health


This master antioxidant is associated with so many health benefits that it’ll make your head spin. 


1. Supports The Immune System 


Having a strong immune system is key to good health. Glutathione is critical to helping the immune system fight infections and prevent diseases like cancer. Glutathione is found in all cells of the body, including the cells of the immune system, which fights disease.

Glutathione’s role in strengthening the immune system is two-fold. First, glutathione increases the count of T-cell lymphocytes, or white blood cells. White blood cells are the star players of your immune system that work to destroy bacteria and viruses.

Secondly, glutathione stimulates the activity and production of natural killer cells. Say what?! A natural killer cell is no Charles Manson or Ted Bundy—it only kills the bad guys. A type of lymphocyte, natural killer cells rapidly eliminate virus-infected cells from the body. Take that, disease!


2. Removes Free Radicals and Heavy Metals From The Body


All antioxidants capture and remove free radicals from the body. So, why is glutathione the leader of the pack? Because it is found in every cell of the body, say the experts.

Gustavo Bounous, MD, director of research and development at Immunotec and a retired professor of surgery at McGill University in Montreal, Canada, said, "It's the body's most important antioxidant because it's within the cell."

You heard that right.

Glutathione is in an advantaged position for fighting free radicals because it is intracellular. Glutathione also teams up with other antioxidants like vitamin C, vitamin E, and selenium to support them in destroying free radicals.

But that’s not all. Glutathione helps to remove heavy metals like arsenic, lead, and mercury from the body. Heavy metals enter the body through inhalation, ingestion, or absorption. Long-term, low-level exposure to heavy metals is detrimental to your health. It can lead to problems like diabetes, liver damage, and kidney damage. Glutathione binds to heavy metals in the body and moves them out of the tissues. So, the first step to eliminating heavy metals from your body is to raise your glutathione levels.


3. Detoxifies The Body 


We’re constantly bombarded with toxins in our daily lives from cigarette smoke, household cleaners, plastic food containers, pesticides, fertilizers, pollution, UV rays, blue light, prescription drugs, you name it. While it might be healthier to abandon your modern lifestyle and move to an isolated forest to subsist on foraged nuts and berries, that’s not a realistic or even desirable plan for most. One of our best defenses against the toxins in the modern world is, you guessed it—glutathione.

According to studies, glutathione has multiple detoxification functions. Glutathione binds to toxins, pulls them out of the cells, and carries them to the liver where they are processed and then excreted through the kidneys, lungs, or bowels.

4. Lightens and Brightens The Skin


You don’t have to become a sun-deprived hermit to lighten your complexion. To get porcelain-like skin, consider brightening your skin tone with glutathione treatments. Glutathione converts melanin to a lighter color and deactivates tyrosinase, an enzyme that helps to produce the pigment.

In countries like the Philippines, glutathione treatments have been used for many years to brighten skin, achieve a more even skin tone, and diminish blotches and scars. One study showed a lightening in skin color among its subjects after just 4 weeks of orally administering glutathione.


5. Decreases the Signs of Aging Skin 

Age may make you wiser, and it certainly makes a bottle of wine more flavorful, but it doesn’t do your skin any favors. As you get older, your skin starts to break down, leading to wrinkles, fine lines, dryness, discoloration, thinness, and a lot of other icky symptoms. While aging isn’t totally avoidable, you can turn back the clock and achieve a more youthful, radiant complexion with the aid of glutathione.

Glutathione is one of the world’s lesser-known anti-aging secrets. It protects the skin against oxidative damage and detoxifies the skin and body, helping to reverse acne and wrinkles. Glutathione also protects skin cells from UVA and UVB rays and HEV light, and it plays a critical role in repairing wound tissue.

Studies show taking oral glutathione 250grams/day have positive anti-aging beneficial effects on skin properties.

How can you ensure you have ample supply of Glutathione?


Now you know how important this glutathione is to your health and maintaining youthful skin!

Unfortunately, our body alone can’t make enough glutathione to counteract the negative effects of modern living. We’re all susceptible to the perils of oxidative stress. But there’s hope. You can optimize levels of this antioxidant bad boy with a healthy diet and supplementation.


3 Ways to Boost Glutathione 


Studies have demonstrated the anti-aging effects of the oral administration of glutathione. So, what are you waiting for? Here’s what you can do to defend yourself against aging and free radicals to take back your health and rejuvenate your skin. 


1. Consume Foods That Support Glutathione Production


Sulfur-Rich Foods 


Glutathione levels in the liver and lungs take a nose-dive when your intake of sulfur amino acids is insufficient. A diet rich with glutathione can help boost your glutathione levels and your body will thank you.

Foods high in sulfur include:

Green leafy and cruciferous vegetables: broccoli, kale, collards, cabbage, cauliflower.

Sulfur Rich Food


Selenium-Rich Foods: Precursor to Glutathione Synthesis


Selenium is a powerful anti-oxidant and our body needs selenium to create glutathione.

Food rich in selenium includes:

  • Brazil nuts
  • tuna, halibut, sardines
  • animal meat protein
  • eggs
  • spinach


Cysteine-Rich Foods and Supplements:


Whey protein provides a great source of cysteine and the amino acid building blocks for glutathione synthesis.

It is the precursor to glutathione synthesis.

2. Exercise To Boost Glutathione 


According to Dr. Hardick, exercise is one sure way to boost glutathione naturally. The first longitudinal study measured the effect of exercise on glutathione levels and it shows a positive connection.

It is recommended that a combination of cardio and weight training is most effective to boost glutathione production naturally.


3. Take Glutathione Supplements and Glutathione Supporting Supplements


Sometimes it is hard to determine how much glutathione you have from the food you eat. One of the most effective ways to ensure you have a good supply of glutathione is by taking glutathione supplements.

Oral glutathione supplements are known as L-glutathione, reduced glutathione, or GSH. Taken by mouth, glutathione can help to neutralize toxins, strengthen the immune system, and slow the signs of aging. It can also help to reduce melanin production and lighten the skin naturally.

There are also other supplements besides glutathione itself that you can take to optimize glutathione levels in the body. The supplement N-Acetyl-L-Cysteine (NAC) is shown to naturally increase the body’s production of glutathione. NAC is actually a precursor to glutathione. Studies show that it is helpful in treating psychiatric disorders like addiction, schizophrenia, and bipolar disorder. 

Dr. Hyman MD also recommends taking Whey Protein and Alpha Lipoic Acid because both of them can help stimulate glutathione production in the body.

Whey protein provides a great source of cysteine and the amino acid building blocks for glutathione synthesis. 

According to Dr. Hyman, Alpha Lipoic Acid is a close second to glutathione in importance in our cells and is involved in energy production, blood sugar control, brain health, and detoxification. The body usually makes it, but given all the stresses we are under, we often become depleted

There is also some evidence that vitamins C and E can help raise glutathione levels. Studies have shown that vitamin C raises glutathione in red blood cells and improves the overall antioxidant capacity of blood. Vitamin E is an important antioxidant that has been shown to prevent damage from reactive oxygen and protect glutathione-dependent enzymes.

A family of antioxidants including vitamins C and E (in the form of mixed tocopherols) work together to recycle glutathione.


How About Topical Glutathione Treatments?


Topical glutathione treatments are a clinically proven way to effectively whiten the skin and improve the skin’s condition. According to one 10-week study, the application of glutathione lotion led to a significantly lower skin melanin index as well as improved moisture, suppressed wrinkles, and smoother skin.

However, oral glutathione supplementation is more effective if you want to treat the whole body and experience a wider range of benefits rather than just treat a specific area.
