Max GXL is a glutathione supplement. Originally manufactured by Max International, Max GXL is supposed to increase the levels of glutathione (GSH) in the body, which come down naturally as you age. The supplement does not contain any direct GSH, but it uses ingredients to trigger its production in the body and provide you with anti-aging benefits.

Max GXL contains vitamin-C and several other natural ingredients that help boost your immune system, slow down the aging process, improve heart and lung function, and enhance concentration. It certainly makes big claims, but we have reviewed it in detail to help you decide if it is worth your time and money.

Max GXL Pros

  • May improve immune function somewhat
  • Uses a combination of natural ingredients
  • May help boost energy production a little

Max GXL Cons

  • Contains a proprietary blend
  • Company has a tainted reputation
  • No money-back guarantee

What You Need To Know About Max GXL

Max GXL is designed to stimulate the production of molecule called glutathione, which works as an antioxidant and antitoxin in the body. By using a combination of ingredients, Max GXL claims to strengthen your immune system, slow down the aging process, prevent lung and heart disease, and detoxify your liver to improve overall health. Unfortunately, it fails to fulfill all of its claims, as we could not find satisfactory customer reviews supporting the claims they have made.

What Are The Side Effects Of Max GXL?

There is no information available about the side effects on the original website, but Max GXL includes certain ingredients that may be associated with side effects, such as nausea, vomiting, and gastrointestinal discomfort. It contains several ingredients that make it quiet ‘unsafe’ during pregnancy and breastfeeding. Check our ‘Side Effects’ section for complete details.

How Much Does Max GXL Cost?

Max GXL costs you $65/bottle, but some sites may offer it at a discounted price – you should still expect to spend more than $50 to get it.

Our Verdict On Max GXL

Max GXL makes big claims, but it fails to deliver any results. Most people are reluctant to make a purchase considering the fact that Max International has to deal with a lawsuit in the past for not offering correct information about their products. You could find links to clinical studies confirming that Max GXL works, but all links to those studies are dead. It makes you wonder if they are just trying to trick you into making a purchase.

Customer reviews are not satisfactory either, with most people seeing no results. We are not in favor of products with proprietary blends, and Max GXL falls into that category. We do not know what is there in the blend, so we cannot say what sorts of side effects you may have to deal with. So, avoid it and look for something better!

Max GXL Review

Max GXL is a dietary supplement that uses several vitamins and herbs to help increase the levels of glutathione in the body. It does not contain GSH but claims that the ingredients in the supplements help trigger the production of glutathione naturally. Unfortunately, it fails to live up to the hype, which is mainly because many of its ingredients do not work as claimed and others are under-dosed.

The presence of n-acetyl d-glucosamine is actually a good thing because it may help protect intestinal lining and boost your immune system to certain extent. However, it is not going to work if you do not take enough of it, and that seems to be the case with Max GXL. There is no information about how much of n-acetyl d-glucosamine is in the supplement, but considering the customer reviews about the product, we believe there is not enough.

Max GXL Facts

  • A combination of herbs and vitamins
  • 180 capsules per bottle

It contains milk thistle, which helps boost liver health. They have included it in the blend thinking that since glutathione is produced in the liver, improving liver health would automatically increase the production of GSH. This is not always the case, and we cannot say how much more GSH will be produced. Moreover, there are no details about how much of milk thistle is there in the blend – you need to take at least 140mg thrice a day to have its antioxidant effects. We believe that milk thistle is under-dosed in Max GXL.

Max GXL includes cordyceps, a genus of fungi, to provide you with anti-tumor and anti-diabetic benefits, but there is not enough evidence to confirm its therapeutic benefits. No information about the amount of cordyceps used in Max GXL makes it even difficult to confirm if this ingredient really makes a difference. A lack of human studies means that there might be several side effects not discovered yet. Therefore, it is not a great choice either.

How to Take Max GXL

Max GXL provides you with 180 capsules per bottle. You have to take 3 capsules two times daily to see some results. You can take it with water. It means you will get a 30-day supply for up to $65.

We do not know how much of quercetin is there in this supplement, but many studies have shown that quercetin may work as an antioxidant and even posses antihistamine and anti-inflammatory properties. The problem is that it works only when you take an adequate amount of quercetin on a regular basis, but we believe that it is under-dosed in Max GXL because its antioxidant effect is not that prominent. Another important thing to bear in mind is that you do not always need to use a supplement that contains quercetin because you can get loads of it from dietary sources, such as citrus fruits, red wine, tea, sage, dark cherries, and dark berries.

It is good to get so much vitamin-C from Max GXL. This may help improve your immune system and even prevent free radical damage. It also plays a role in the production of the neurotransmitters, norepinephrine and serotonin. Should you spend over 50 bucks just to get a supplement loaded with vitamin-C only? We do not think so really. You can get so many supplements with vitamin-C at a much lower price. Moreover, you do not need that much if you are not already deficient in it. High doses of vitamin-C may lead to certain problems such as kidney stones, blood clots, and toxicity. You have to be careful when using a vitamin-C supplement in pregnancy.

Max GXL Concerns:

  • No money-back guarantee
  • No mention of scientific research
  • Very expensive
  • Lawsuit filed against the manufacturer

It also includes L-glutamine and N-acetyl cysteine to trigger the production of glutathione, but there is not reliable data to confirm if these ingredients are really going to work in that way, and even if they do work how long it will take them to raise the levels of GSH to a considerably level. Therefore, we believe it is better to switch to dietary sources to increase your GSH levels and do not rely on something as ineffective as Max GXL.

In terms of formula, Max GXL fails to impress, but it is important to point out that they may not be the most reputable supplement companies out there. They have faced legal issues for not sharing authentic details about their products. We checked the official website and noticed that they have mentioned how different studies have confirmed the usefulness of Max GXL. Unfortunately, the links are dead and you cannot actually confirm if their claims are right. They do not offer a money-back guarantee either, so you are surely going to lose your money if you decide to try it. We believe you should look for another supplement with scientifically proven ingredients and no proprietary blend, so you could know what to expect when using it on a long-term basis.

What Does Max GXL Claim To Do?

Max GXL is a dietary supplement geared towards elderly folks who are supposed to have low levels of glutathione – it is a molecule responsible for keeping your immune system working at its best. They claim that anyone can take it to slow down aging by triggering the release glutathione. Here are some other claimed benefits:

  • It helps boost immune system
  • It helps improve memory
  • It helps boost energy production
  • It helps slow down aging effects
  • It helps keep your skin in good condition
  • It helps detoxify your body

Does Max GXL Work?

Max GXL contains vitamin-C and many other ingredients that look good on paper, but it seems that the formula lacks some power and fails to deliver promised results. The proprietary blend leaves us wondering how much of everything is included in the formula, which makes it difficult to know about its side effects. Still, we know it is not safe for pregnant women, and people with allergies should avoid it too. It may help boost your immune system, as it includes vitamin-C, but do not expect much in terms of anti-aging benefits. Unfortunately, Max GXL is not a good choice- look for another supplement backed by actually clinical studies and positive customer reviews.

What Are The Ingredients of Max GXL?

Max GXL offers a combination of natural ingredients, which helps slow down aging process, boost immune system, and improve heart function.

  • N-Acetyl D-Glucosamine: It contains n-acetyl D-glucosamine, which is supposed to protect the lining of the intestines and stomach, and help improve your immune system. However, we have no information about how much of it is in Max GXL.
  • Milk Thistle: Used mainly to promote liver health and trigger the release of glutathione, Milk Thistle is a nice choice, but is definitely not free of potential side effects.
  • Cordyceps: Used in traditional medicine to help improve kidney function, cordyceps can cause several side effects and have no real human study to confirm the benefits.
  • Quercitin: Found in veggies and fruits, quercetin is supposed to work as an antioxidant in the body, which helps protect you from chronic diseases, including cancer and heart disease. It may also have an anti-inflammatory effect.
  • Vitamin C: You get plenty of vitamin-C from Max GXL. You need vitamin for proper wound healing and functional immune system. It acts as an antioxidant but too much of it can lead to certain problems.
  • L-Glutamine: You get lads of L-glutamine from Max GXL, which is supposed to improve your digestive health and boost your immune system. It helps eliminate waste product ammonia from the body, but may increase your risk of experiencing chest pain, hearing problems, dizziness, and joint pain.
  • N-Acetyl Cysteine (NAC): Usually used in the treatment of liver toxicity and chronic bronchitis, NAC may also help trigger the production of glutathione.
  • Alpha Lipoic Acid: Produced naturally in the body, Alpha Lipoic Acid acts as an antioxidant and lowers your risk of stroke, liver disease, glaucoma, and diabetes. Overdose can cause lightheadedness, nausea, and skin rash.

Does Max GXL Have Any Side Effects?

No real information about the side effects of Max GXL is available on the official website, but we are not comfortable recommending it because it uses a proprietary blend, which provides no information about how much of each ingredient is there. For instance, it contains n-acetyl-d-glucosamine, but too much of it can increase the amount of insulin in the body, which could lead to high levels of cholesterol and hypertension. It is not safe during pregnancy, and it can also make asthma worse.

Similarly, it contains milk thistle, but we do not know how much of it is there. Its use is associated with allergic skin reactions, decreased platelets, eczema, diarrhea, fever, elevated liver enzymes, headaches, giddiness, increased bilirubin levels, liver damage, loss of appetite, nausea, and insomnia.

Cordyceps supplements can also cause several side effects. The most common side effects are nausea, upset stomach, and diarrhea. But, you need to bear in mind that this ingredient has not been studied extensively, which means there could be many other side effects waiting to be discovered.

The presence of quercetin may also produce certain side effects, including upset stomach and headache. Some studies have shown that excessive intake of quercetin may lead to a loss of protein function. Moreover, it may damage the kidneys, so it is better to avoid it when you have a kidney disease. Pregnant women should also avoid quercetin.

The presence of vitamin-C is another reason why you are likely to experience gastrointestinal problems while taking Max GXL. It can cause problems like chest pain, dizziness, faintness, diarrhea, flushing, headache, inflamed esophagus, heartburn, skin irritation, and urinary complications. The risk of experiencing these symptoms may go up because Max GXL also contains L-Glutamine and alpha lipoic acid.

Are There Any Customer Reviews For Max GXL?

There are not many reviews for Max GXL, but most people have not noticed any immediate benefits after taking it for a few days.

I’ve been taking Max GXL 5pills twice a day for the last 5 days. I was told it helped a lot with inflammation and nerve pain. I have some pain in my legs and thighs from a hernia surgery. Thus far I haven’t noticed any difference.

I Finished the bottle and followed the directions on how to take it. But did not see any improvement or benefits by taking it. I will NOT reorder.

Does Max GXL Offer a Money-Back Guarantee?

No, you do not get a money-back guarantee with Max GXL.

Where Can I Buy Max GXL?

You can buy it from Amazon and some other third-party retailers.

  1. Maxgxl is useless. It was developed by a Dr. Robert Keller. He has died from
    Amyloidosis. I checked and found out that Amyloidosis can be caused by a deficiency of… guessed it, “Glutathione”. So, if maxgxl was so good, Keller would still be alive!
