5 Best Marshmallow Root Supplements

Nature’s Way Marshmallow Root

Nature’s Way Marshmallow Root Review
CONTENT:

480mg marshmallow root capsules

PRICE/NUMBER OF CAPSULES:

~$12/100 capsules

2 capsules daily with food or water

Pros

  • Non-GMO, vegan-friendly
  • One of the top-rated marshmallow root supplements
  • Reviews mention benefits for stomach problems and interstitial cystitis (a chronic condition causing bladder pain)
  • Reviews also include benefits for sore throat and urinary problems

Cons

  • Capsules are big and might be hard to swallow
  • May have an aftertaste

First on our list is the Nature’s Way marshmallow root vegan capsules. It’s also one of the most popular marshmallow root supplements in the market with a 4.6/5 customer rating on iHerb and Amazon. A notable feature of this brand is aside from it being organically grown, it’s also part of the non-GMO project. This is a label you’ll see also in products tested by a nonprofit organization that has verification systems to make sure it’s not genetically modified (GMO) and doesn’t have GMO ingredients.

The brand keeps it simple by advertising this supplement as a traditional way to soothe digestion, but a lot of the reviews cited how the product also worked for a wide variety of health conditions. Moreover, some of the commonly mentioned are symptom improvement of interstitial cystitis (IC), sore throat, UTI, acid reflux, and leaky gut.

Although the majority of reviews are good results, a few of them reported not experiencing the benefits right away, but other reviews note that you’ll most likely see results after 2-4 weeks. The brand also recommends taking 2 capsules (960mg total) a day. 


Solaray Marshmallow Root 

Solaray Marshmallow Root Review
CONTENT:

480mg marshmallow root capsules

PRICE/NUMBER OF CAPSULES:

~$10/100 capsules

1-3 capsules daily with a meal or a glass of water

Pros

  • Non-GMO, vegan-friendly
  • Eco-friendly packaging (100% PCR recycled plastic bottles)
  • More affordable compared to other brands
  • Reviews mention benefits for cough and digestion problems

Cons

  • May have an aftertaste
  • People taking medications may have to consult with their doctors before taking this supplement to avoid drug interaction

With an average of 4.7/5 rating on iHerb and Amazon, it’s also one of the most familiar brands that gained a bunch of good reviews. It’s cheaper than other brands but doesn’t compromise quality because it’s lab-verified for potency and purity, plus it’s vegan-friendly and non-GMO.

Customer reviews also support its advertised benefit—for healthy respiratory function and digestion support. Those who suffer from leaky gut (a digestive condition of unhealthy gut lining due to bacteria and toxins leaking through the intestinal wall) reported symptom improvement after about 2 months. Several reviews also mention benefits for common digestion and stomach-related issues like irritable bowel syndrome (IBS), acid reflux, and IC, as well as for relieving cough.

Another notable feature of this product is the brand’s commitment to using 100% post-consumer recycled (PCR) plastic bottles for their packaging. However, based on some reviews, you may notice an unpleasant aftertaste, so it’s good to take it with a meal or a glass of water. 


Bulk Supplements Marshmallow Root Extract 

Bulk Supplements Marshmallow Root Extract Review
CONTENT:

100g marshmallow root extract powder

PRICE/NUMBER OF CAPSULES:

~$14/100g 

Take 1200mg (about ½ tsp) once or twice daily with meals

Pros

  • No additives
  • Lab-verified, third-party tested 
  • Manufactured to current good manufacturing practice (cGMP) standards
  • Reviews mention that the powder is easy to use and has a mild flavor

Cons

  • Limited product information available
  • Doesn’t thicken when added to liquid according to some reviews

This next product offers a unique approach because instead of the usual capsule, it’s an extract in powder form. Bulk Supplements marshmallow root extract has no other ingredients, hence, it’s free of added sugar, soy, gluten, and other additives. From over 600 reviews on Amazon, it also has an average of 4.5/5 rating as of this writing.

Moreover, one advantage of this powder-type supplement is its flexible use, which a lot of customers like. Some also mix it in their hot tea or coffee, use it as a DIY shampoo to detangle hair, or combine it with skin care products like lotion. A handful of reviews also say that this supplement helps relieve symptoms of stomach problems like gastritis and GERD, bladder problems such as IC, as well as cough and sinusitis. 

Furthermore, the brand says that the product is rich in antioxidants, may aid in digestion, and support the heart, lungs, and skin health. But some customers expressed that it somehow lacks product information—like how it was extracted and why it’s brown (apparently, other marshmallow root extracts are white). However, because it’s in powder form, it might still be a good option for people who don’t like taking capsules.

FAQs

What Are Marshmallow Root Pills Good For?

Marshmallow root contains a high amount of soluble fiber called mucilage. It’s a sap-like substance that contains antioxidants. In addition, research suggests that the medicinal properties of this plant come from the mucilage which may soothe inflammation of the mucous membranes in the body.

Because of this effect, it’s traditionally used to relieve dry cough and sore throat, as well as urinary tract infections, stomach ulcers, and other digestive issues. [1]

Does Marshmallow Root Heal a Leaky Gut?

Someone with a leaky gut has an unhealthy digestive tract lining and may experience symptoms such as bloating, cramps, and pain in the stomach. Moreover, research suggests that the mucilage of this plant can create a protective layer on the gut lining. This may also help with the symptoms by soothing the inflammation.[1]

Does Marshmallow Root Affect Hormones?

A study involving animals says that the effect is dose-dependent but also notes that the potential negative effects are balanced by the positive ones. However, further research is warranted.[2]

When Should I Take Marshmallow Root Capsules?

Marshmallow root capsules can be taken at any time of the day, as long as with water or meals to reduce the chances of having side effects.

Conclusion

Considering its history as an effective herbal medicine and low risk of side effects, marshmallow root supplements can be a good home remedy for various minor health issues. As with any supplement or herbal medicine, talk to a doctor before using it, and do not substitute your doctor’s recommended treatment with herbal remedies.
