Introduction 

Glutathione often called the “master antioxidant” is pretty well known. Our bodies need it to stay healthy and strong. It’s found in all of our cells, and it has lots of  functions in our body. It helps us get rid of toxins, boosts our immune systems, and protects us from harmful molecules called free radicals. But as we get older, our bodies don’t make as much of it. Because of this, we’re more likely to get sick. This article is packed with tips on how to increase your glutathione levels safely and naturally. Lastly, we will answer some frequently asked questions regarding this topic. 

Understanding Glutathione 

In this section we will try to understand what glutathione is and it’s functions in the body.  

What is glutathione? 

Glutathione is a tiny protein made up of three different substances which is cysteine, glutamic acid, and glycine. Together, they act as a powerful tool to fight off dangerous molecules we come across every day from factors like pollution and certain types of foods. 

Glutathione’s role in the body 

Glutathione carries out many tasks within the body which are as follows.  

• It fights off harmful molecules to keep our cells from getting damaged. 
• It helps our liver get rid of toxins. 
• It helps build and repair our body’s DNA. 
• It helps our bodies make use of other helpful nutrients like vitamins C and E. 
• It strengthens our immune system by controlling swelling and boosting the function of certain immune cells. 
   

The forms of glutathione 

There are two types of glutathione in our bodies, a type called reduced glutathione (GSH for short), and another called oxidized glutathione (GSSG). When GSH gets busy fending off harmful molecules, it becomes GSSG. But don’t worry, our bodies can change GSSG back into GSH so it’s ready for action again. 

Natural Ways to Increase Glutathione Levels 

Below we have described natural ways that may help our bodies get enough glutathione. 

1. Consume sulfur-rich foods 

Eating foods that are rich in a mineral called sulfur is one way. Foods like broccoli, kale, cauliflower, and Brussels sprouts are great choices for this. 

2. Increase vitamin C intake 

Vitamin C is also important because it helps our bodies store more glutathione. Foods like citrus fruits, kiwis, and strawberries are all high in vitamin C. 

3. Add selenium-rich foods to your diet 

Then there’s selenium, which directly helps make glutathione. Foods like fish, organ meats, and Brazil nuts all contain lots of selenium. 

4. Eat foods naturally rich in glutathione 

You can also eat foods that naturally contain glutathione, like broccoli, avocados, spinach, and asparagus. 

5. Supplement with whey protein 

Another option is supplementing your diet with whey protein. It’s brimming with cysteine, one of the building blocks of glutathione. 

6. Consider milk thistle 

Milk thistle supplements, which contain a helpful compound called silymarin, could help as well. Animal studies have shown that it boosts glutathione levels. Run it by your doctor before using it.  

7. Try turmeric extract 

The spice turmeric, which contains a powerful antioxidant called curcumin, may also help. More research is needed here though. 

8. Get enough sleep 

Don’t forget the importance of sleep, either. Not getting enough of it can lower your glutathione levels. 

9. Exercise regularly 

Regular exercise can also help. But remember to keep it balanced and don’t overstrain. Keep your diet varied and ensure you rest plenty. 

10. Avoid drinking too much alcohol 

Drinking too much can bring your glutathione levels crashing down. It does this mainly by lowering levels in the lungs. So, try to limit how much you drink. 

Glutathione Supplementation 

If these natural methods aren’t working, you might consider glutathione supplementation. But keep in mind, there are potential risks and side effects.

Benefits of Supplementation 

 Some research claim the following regarding glutathione supplementation. 

• They may boost the function of certain immune cells and control swelling. 
• They are proposed to help the liver get rid of toxins and deal with harmful substances 
• They are said to reduce the effects of harmful molecules, which may protect against chronic illness and brain diseases. 
• They may help the body make use of other helpful nutrients like vitamins C and E. 
• They may help improve skin health by lightening dark spots and reducing signs of aging.  

Always remember to consult your doctor before incorporating these supplements into your routine.  

Potential Risks and Side Effects 

However, glutathione supplements are not for everyone. There are risks and side effects to bear in mind which are as follows.  

• Risks for some users: There isn’t enough information to show that these supplements are safe for pregnant or breastfeeding people. If you have any existing health problems or are taking other medicines, ask your healthcare provider before using glutathione supplements. 
• Possible reactions: Taking oral glutathione could cause issues with your stomach. You might experience things like bloating, cramping, or loose stools. Plus, inhaling glutathione could make mild asthma symptoms worse due to sulfites. 

How to Choose a Glutathione Supplement? 

• Choosing the source: It’s best to buy from brands that use high-quality sources like whey protein. 
• Check before you buy: Look at the product’s purity, quality, and strength. Also, make sure it’s been third-party tested. Consider the format (like capsules or liquid), cost, and dose as well. 

Recommended Dosage for Glutathione 

It depends on things like your age, sex, and medical history. Ask your healthcare provider to know the best dose for you. 

1. General dosage guidelines 

Daily, most people may take between 250 and 500 mg of oral glutathione. Studies suggest you need at least 500 mg a day for two weeks or more to notice a change in your levels. Always take the dose recommended by your doctor.  

2. Different conditions and recommended dosages 

The right dose might vary based on the circumference .  

• Cystic fibrosis: A study gave children with cystic fibrosis 65 mg/kg/day of oral reduced glutathione for six months.  
• Parkinson’s disease: A clinical trial gave 1,400 mg of glutathione through injection three times a week for four weeks. 

Interactions with Other Medications and Substances 

If you’re already on medication or taking other substances, you might need to think twice about glutathione supplements: 

Drug interactions possible 

Glutathione might not react well with some medications, especially ones used in chemotherapy. Also, too much acetaminophen can lower your levels of glutathione, which could increase its toxic effects. Always ask your doctor before you start glutathione supplements if you’re on any medications. 

1. Substances that may deplete glutathione levels 

Certain factors can bring down your glutathione levels too which are as follows.  

• Constant stress 
• Poor diet 
• Drinking way too much alcohol 

Be aware of these and make changes in your lifestyle where needed to keep your levels up. 

2. Substances that may increase glutathione levels 

On the flip side, there are foods and nutrients that can support glutathione production which are as follows.  

• Foods full of sulfur  
• Foods packed with vitamin C  
• Foods that contain selenium  

Glutathione for Skin Lightening 

Some people use glutathione to lighten their skin and reduce dark spots. However, this use is  controversial, and more research is needed. 

1. How does glutathione aids in skin lightening? 

Glutathione might work by blocking the action of an enzyme called tyrosinase. If this enzyme isn’t doing its job, the body will make more of a lighter pigment, instead of a darker one that gives skin it’s colour. 

2. Effectiveness and safety 

On one hand, preliminary evidence suggests that oral and topical glutathione could temporarily lighten skin. They’re mostly well-tolerated. On the other hand, we still need more large-scale studies to be sure that it works and find out the best doses and formats to use. 

3. Potential side effects 

The practice of injecting glutathione for skin lightening is a major safety concern. The US Food and Drug Administration has warned against injecting skin-lightening agents such as glutathione due to risks like severe problems with the liver and potentially life-threatening reactions. 

Conclusion 

Glutathione is a really important antioxidant that does so much to keep us healthy. Maintaining your body’s natural glutathione levels is key. This may be done through your diet, lifestyle, and in some cases, supplements. But be mindful of the potential risks and side effects tied to glutathione supplements, and always talk to your healthcare provider before starting something new. 

At the end of the day, a balanced lifestyle, a good diet, regular exercise, and enough sleep may go a long way in supporting healthy glutathione levels.
