How to Improve Your Child's "Waste Removal System" to Improve their Autistic Symptoms

How to Improve Your Child's Waste Removal System to Improve Autistic Symptoms

Before we dive into how you can supercharge your child’s waste removal system and actually improve their autistic symptoms, I want to highlight something.

We’ve published other articles showing how certain supplements and diet changes can help improve your child’s autistic symptoms. If you want the best results for your child, these different strategies actually work best together. 

Not only should you remove MSG from your child’s diet, but you should also fix their gut bacteria and gut lining. Using glutathione and other supplements to improve your child’s ability to remove waste from their system works better if we aren’t putting in waste in the first place and their body is better able to handle it with better gut lining and bacteria.

If you want all the articles from this series in a nicely designed eBook, simply click below and enter your email address. We’ll send it to you right away.

Using Glutathione to Improve Your Child’s Autistic Symptoms

Quick Note: Make sure your child is supplementing with vitamin C and E which are great for antioxidant support. Those are easy to find and simply help support our bodies natural defense system.

However, what we want to focus on here is improving their ability to produce glutathione. Glutathione is our bodies natural powerhouse when it comes to antioxidants. It helps neutralize free radicals, regulate our blood pressure and inflammation, helps the liver process toxins, and plays a role in DNA synthesis.

Glutathione is obviously important. However, people with autism have impaired waste removal systems. This means their bodies don’t produce glutathione like it should.

The big problem here is, we can’t directly supplement with glutathione. Taking a direct glutathione supplement has been shown not to be very effective.

But there is good news! It turns out that if we supply the body with more glutathione precursors (the building blocks the body uses to make glutathione), the body will start to produce more glutathione!

Using N-acetyl-cysteine (NAC) to Produce more Glutathione

The first thing we can look into is supplementing with N-acetyl-cysteine (NAC). NAC is typically an asthma remedy, but in one study children with autism who supplement with NAC over 12 weeks showed an 80% reduction in ABC Irritability subscale scores compared to the group who didn’t.

Make sure you work with your doctor before using a NAC supplement for your autistic child. They will be able to shed more light on them and help get your child the correct dosing since it’ll be different for every child. I really want to stress this, that working with a medical professional is key to getting all this right.

Why Whey Protein is Great for Your Child

Next, and an easier one to supplement with is whey protein. Whey protein is derived from dairy, so it may be best to go with goat whey protein to avoid problems with dairy and casein. I recommend this one by Teras. 

The reason you want to supplement with whey protein is that it replenishes glutathione by providing the precursor cysteine. This makes it a great supplement to help support glutathione when it comes to increasing metabolism and strengthening the immune system. 

However, although this is a great supplement to support glutathione, this is one you'll want to be careful about implementing. While goat milk has less casein than cow’s milk, there still is some casein in it. So work this in slowly, testing to see if your child has a negative reaction to it.

If you have already healed their gut lining and improved the makeup of their gut microbiome, their ability to digest casein, in general, should be better. 

Veggies that help Produce Glutathione

Next, you’ll want to add sulfuric foods to your child’s diet. It has been shown that when your sulfur amino acid intake is low, your glutathione levels drop. Here’s a quick list of foods to consider adding to the diet:

  • Arugula
  • Bok Choy
  • Broccoli
  • Brussels Sprouts
  • Cabbage
  • Cauliflower
  • Collard Greens
  • Kale
  • Mustard Greens
  • Radish
  • Turnip
  • Watercress

Now, getting your child to enjoy some Brussels sprouts or kale may sound like a crazy challenge. However, if you get creative, you can probably pull it off!

A couple of ideas to help:

Kale Smoothies

  • Almond Butter
  • Kale
  • Yogurt (if you’ve slowly worked it back in after healing their gut bacteria)
  • Frozen Banana
  • Frozen Berries
  • Kefir (once again, slowly worked in since it’s dairy)

This smoothie will actually taste very sweet and like almond butter. The Kefir and Yogurt are full of good bacteria for your child’s digestive system.

Cauliflower Rice

If you put cauliflower into a food processor, it eventually gets down a texture like rice. You can use this as a base for other foods or on the side of meals.

Cauliflower Mashed “Potatoes”

If you chop up cauliflower, steam it until it’s soft, then blend it in a food processor, adding chicken stock along the way, you get a mashed potato-like texture.

Roasted Vegetables

Brussels sprouts and broccoli definitely taste better if you put a little olive oil, salt, and pepper on them and then bake them in the oven until they are soft enough for a fork to easily go in and out.

Vitamin B

Another supplement we’ve seen before that will help with the waste removal system is vitamin B. Vitamin B has been said to be “perhaps the most critical to keep the body producing glutathione” by Dr. Mark Hyman.

Supplementing will help, but some good foods to get it naturally are:

  • Liver
  • Spinach
  • Asparagus
  • Avocado
  • Beets
  • Broccoli


Polyphenol-Rich Foods

Lastly, to improve the waste removal system, it’s good to get your child regular doses of polyphenol-rich foods, such as tea, cinnamon, and turmeric. While there’s actually very little science to back up that polyphenols have health benefits like they have been hyped up to be, it certainly doesn’t hurt to give them to your child! Especially turmeric, which is an extremely anti-inflammatory spice.


That’s the protocol for improving the waste removal system. I hope you can see by now, with all the studies and protocols piling up, there’s a huge amount that can be done to improve your child’s autistic symptoms.

Great article. Can you tell me why we can’t supplement direct with Glutathione? Is there an absorption issue? I am aware of a number of supplements including some liposomal. Thanks for your time.

Hey Adam,

Thanks for sharing that info. We really appreciate it. It’s definitely a good idea to look at all possible sensitivities and work to rid them from your diet. Glad you found success in making those changes concerning a low salicylate and low phenol diet.

All the best,

Hi, I’m writing this comment in regard to Polyphenols, it has been shown that a lot of people who experience autistic symptoms have salicylate intolerance,

I made my autistic symptoms practically none existent when I went on a low salicylate and low phenol diet, I’m actually badly salicylate intolerant so eating a bit of that would make my face red and cause a myriad of problems

So maybe revise or put a disclaimer on that polyphenol part, saying that it can increase autistic symptoms, that was the underlying cause of mine and tags also how I cured my rosacea and dust mite allergies

Pharmanac is a NAC in tablets that can be cut in half if needed that make a fizzy fruit flavored drink.We are waiting on our first order and hope they are good. Honeycombs herbal company makes an oral product called NAX which has 22 mg each of vit.C and NAC in a glycerin base. The tablets are much stronger in potency ,but the oral spray has obviously helped our youngest children.
