Your Body's Master Antioxidant

Glutathione is a naturally occurring antioxidant that your body creates to reduce oxidative stress. It plays an essential role in your immunity, warding off diseases such as cancer, diabetes, and rheumatoid arthritis. It also supports a variety of essential functions, including weight loss, improved skin tone, increased energy, improved cognitive function, workout recovery, and more.

Glutathione production naturally slows down as you age. To offset this decline, you may consider taking a daily supplement. Like many supplements, digestive enzymes break down nutrients before they can enter your bloodstream. This has many turning to injectable glutathione.

At Valley Medical Weight Loss and Med Spa, we offer convenient, affordable glutathione injections at all four of our Phoenix metro locations, helping you maintain optimal levels of this powerful antioxidant for whole-body wellness.

What is Glutathione?

Most antioxidants are consumed in the foods we eat, but glutathione is one of the few antioxidants that is produced by your body. It is a tripeptide and a combination of three amino acids:

  • Cysteine
  • Glutamic acid
  • Glycine

Why it matters:

  • Produced naturally by your body
  • Found in every cell
  • Highest concentrations in the liver
  • Critical for detoxification
  • Protects cells from damage
  • Declines with age and stress

Foods That Support Glutathione Production

While produced by your body, there are foods that can stimulate glutathione production. This includes:

Sulfur-rich foods:

  • Broccoli
  • Brussels sprouts
  • Kale
  • Cauliflower
  • Beef

Foods high in vitamin C:

  • Citrus fruits
  • Bell peppers
  • Papaya
  • Strawberries
  • Kiwi

Selenium-rich foods:

  • Brazil nuts
  • Brown rice
  • Chicken
  • Cottage cheese
  • Eggs

Foods that contain glutathione:

  • Avocado
  • Spinach
  • Asparagus
  • Okra
  • Tomatoes

Beneficial herbs:

  • Milk thistle (tea or supplement)
  • Turmeric (cooking or supplement)
  • Cinnamon
  • Cardamom

Lifestyle Factors

Healthline advises that glutathione production also slows down when you don’t get enough sleep and don’t engage in regular physical activity. Even with foods and supplements, to keep up with the rate at which production declines as you age, you may want to consider weekly injections.

Factors that deplete glutathione:

  • Aging
  • Poor sleep
  • Chronic stress
  • Poor diet
  • Excessive alcohol
  • Environmental toxins
  • Smoking
  • Lack of exercise

Now, let’s dive into how glutathione works in your body.

#1 Improved Immunity

Your immune system is your body’s natural defense system, and glutathione plays a vital role in supporting your immunity. We are all exposed to oxidants (aka free radicals and toxins) on a daily basis. From the air we breathe to cleaning chemicals, UV exposure, processed foods, and more. Oxidants decrease immunity, and antioxidants restore immunity by clearing our system of harmful free radicals.

Glutathione can:

  • Help restore the body’s normal immune system function when you are sick
  • Reduce the risk of illness and infections, making it ideal during cold and flu season
  • Regulate internal functions, decreasing your risk of cancer, diabetes, and rheumatoid arthritis
  • Support white blood cell function
  • Enhance natural killer cell activity
  • Reduce the duration and severity of illness

Oxidation also causes internal inflammation, which is something you can’t see, but may feel physically, mentally, and emotionally.

Signs of oxidative stress:

  • Chronic fatigue
  • Brain fog
  • Frequent illness
  • Slow recovery
  • Muscle aches
  • Premature aging

#2 Detoxification

Injected glutathione rapidly enters your bloodstream, where it is synthesized in your liver. Your liver plays a vital role in helping your body detox. Detoxing goes beyond minimizing oxidative stress to removing excess fat stored in your liver.

Glutathione has been proven to improve the protein, enzyme, and bilirubin levels in those with both alcoholic fatty liver disease and nonalcoholic fatty liver disease.

How glutathione supports detoxification:

  • Binds to toxins for elimination
  • Supports Phase II liver detoxification
  • Protects liver cells from damage
  • Helps metabolize medications
  • Removes heavy metals
  • Processes environmental toxin

Even if you don’t have fatty liver disease, you can kickstart weight loss by detoxing, which is why we suggest our injectable glutathione with our MIC shot as part of our Premier Weight Loss Program.

This monthly program is for anyone who is ready to commit to scientifically proven strategies. We also offer a Weekly Weight Loss Program.

On that note, let’s dive a bit deeper into how glutathione aids in weight loss.

#3 Weight Loss

Weight loss is directly linked to your metabolic rate. Your metabolism refers to how much energy (calories) your body requires to do all the things it does on autopilot. This includes digesting nutrients, processing waste, fighting free radicals, balancing hormones, breathing without thought, and more.

Glutathione injections aid in weight loss by:

  • Helping your body build more muscle, which is essential because muscles require more energy than fat
  • Optimizing liver function to burn off more stored fat
  • Regulating blood sugar levels for diabetics and non-diabetics alike, which can minimize weight gain
  • Minimizing muscle fatigue and supporting your body in muscle recovery after working out
  • Reducing inflammation that can interfere with weight loss
  • Supporting mitochondrial function for better energy production

Perfect complement to:

#4, Cognitive Function

Studies find that minimizing oxidative stress in the brain is essential for both everyday cognitive function and minimizing the risk for and progression of neurological disease. This is because oxidants create inflammation in the brain (and body) and kill brain cells.

The less inflammation in your brain, the longer you can stay focused and clear, and the less likely you are to experience brain fog.

Benefits for brain health:

  • Improved focus and concentration
  • Enhanced memory
  • Reduced brain fog
  • Better mental clarity
  • Faster processing speed
  • Protection against cognitive decline

Alzheimer s.gov also found that low levels of glutathione are linked to an increased risk for Alzheimer’s disease. This is exciting news, as a proactive approach to cognitive function is the best approach.

Neuroprotective effects:

  • Protects neurons from oxidative damage,
  • Supports healthy brain aging,
  • May reduce risk of neurodegenerative diseases,
  • Helps maintain cognitive performance

#5 Balanced Hormones

One of glutathione’s many roles is producing hormones, including estrogen, progesterone, and testosterone. While we all experience hormonal fluctuations during different seasons of life, your injections can help your body balance your hormone levels.

For example, insomnia is a common symptom of menopause, but glutathione has been proven to minimize the oxidative stress that contributes to insomnia.

Hormone support:

  • Regulates estrogen metabolism
  • Supports testosterone production
  • Balances progesterone levels
  • Reduces cortisol (stress hormone)
  • Improves thyroid function
  • Enhances insulin sensitivity

There are a multitude of factors that contribute to hormonal fluctuations, including high levels of stress. When you are stressed out, your body produces more of the stress hormone cortisol. Too much cortisol causes a negative ripple effect throughout your body.

This is one of the many reasons to take an active approach to managing your stress. Glutathione can be part of your stress-management routine.

Also consider: Hormone Replacement Therapy (HRT) for comprehensive hormone support

Keep your “why” top of mind:

  • Write it down in your journal
  • Create a vision board
  • Set it as your phone wallpaper
  • Share it with your support system
  • Revisit it weekly

#6 Improved Sleep

Melatonin is another hormone that injectable glutathione can help your body regulate. Melatonin helps you fall asleep, stay asleep, and wake up feeling refreshed.

You can also take melatonin supplements or use creams and patches, but you may be able to minimize your need for them with your weekly amino acid injections.

Sleep benefits:

  • Supports melatonin production
  • Reduces inflammation that disrupts sleep
  • Balances hormones for better rest
  • Improves sleep quality
  • Reduces nighttime waking
  • Enhances recovery during sleep

Just like we mentioned above, reducing oxidative stress in the body minimizes inflammation and improves your quality of sleep. It’s a vicious cycle, as reduced sleep can contribute to decreased glutathione production.

So, if you have trouble sleeping, your weekly injection may be one of the ways to personalize your sleep routine.

Additional Benefits

Skin health and anti-aging:

  • Brightens skin tone
  • Reduces hyperpigmentation
  • Improves skin elasticity
  • Reduces fine lines and wrinkles
  • Protects against UV damage
  • Promotes even complexion

Athletic performance:

  • Faster muscle recovery
  • Reduced muscle fatigue
  • Improved endurance
  • Better workout performance
  • Reduced exercise-induced oxidative stress

Overall wellness:

  • Increased energy levels
  • Better mood
  • Reduced chronic inflammation
  • Enhanced overall vitality
  • Stronger immune response
