Why choose us?

It’s easy! We are the actual manufacturer and never outsource to the lowest bidder. We actually quality check and manufacture the products ourselves. Easily verify our GMP certification. We have +31 years experience and over 10 million bottles manufactured.

  1. Guaranteed Authenticity: Every batch of USP Magnesium Sulfate is carefully sourced and ID tested on our relevant analytical instruments, ensuring safety. We refuse to accept any form of adulteration or flow agents. Every batch undergoes rigorous testing for ID, purity, potency, and microbiology before, during and after manufacturing.
      • Carefully Sourced
      • ID Tested
      • Purity Tested (micro and heavy metal)
      • Tested for Micro and Pathogens on Verified Instruments in BSL-2 Lab
  2. Carrageenan and Surfactant Free Capsules: Did you know that HPMC capsules, often marketed as “Veggie Capsules,” cannot be certified organic due to the chemicals involved in making clear capsules? Veggie capsules can contain hidden toxins, not from HPMC, but from the manufacturing process. FDA regulation 21 CFR 101.100(a)(3)(ii) allows manufacturers to avoid disclosing ingredients in food if present at “insignificant” levels. This is how carrageenan and surfactant chemicals have made it into HPMC capsules made by some capsule manufacturers. Dr. Clark Store keeps excellent control of the quality of the capsules we use. Nowadays industry insiders know to be wary of the possibility of carrageenan in capsules. According to our sources all HPMC capsules contained carrageenan and surfactants until about 2022. However, over 30 years ago, Dr. Hulda Clark knew not to use HPMC capsules. As a result NONE of Dr. Clark Store products contain HPMC capsules. All our products come in pure BSE free gelatin capsules, free from bones and prion risks. We ensure the highest safety and quality by using only the finest gelatin, just as Dr. Clark intended.
  3. Verifiable GMP Certification: Don’t trust flashy graphics about GMP claims! If someone tells you their factory is GMP certified without proving it to you, it's an empty promise and generally NOT TRUE. All our products are quality controlled by our manufacture and quality assurance company, VeriGMP®, a UL-certified company, ensuring testing and manufacture compliance with strict GMP quality systems. Instructions on how to verify our GMP certification can be found on our website/ Amazon company page. 
  4. No Magnesium Stearate and No Hidden Processing Aids: Only verified and thoroughly tested active ingredients, exactly as Dr. Clark wanted. No magnesium stearate. No processed chemicals. No toxic processing aids. All ingredients declared on the label.
    Manufacturers frequently add magnesium stearate to powders to be encapsulated in order to double or triple the speed of encapsulation. As mentioned FDA regulation 21 CFR 101.100(a)(3)(ii) allows manufacturers to avoid disclosing ingredients in food if present at “insignificant” levels, most manufacturers understand that they can add up to 3% of magnesium stearate without reporting this on the label. We never use magnesium stearate in any of our products! Never have and never will!

  • Relief from occasional constipation*
  • Liver and gallbladder cleansing aid*

Epsom salt is named after the saline spring at Epsom in Surrey, England where it was discovered. Epsom salt is a naturally occurring mineral compound composed of magnesium and sulfate, hence it is also called magnesium sulfate. Epsom salt has been well-documented through the years for its health and well-being benefits, and has been helpful in household chores and gardening task, too.*

As a dietary supplement
Magnesium plays an array of roles in the body. It helps to regulate enzymes that facilitate various functions in the body.*

While bones and teeth are heavily reliant on calcium to maintain structure and strength, calcium absorption is enhanced by magnesium. It also helps to regulate heart beat and supports normal blood pressure levels. And sulfates help to improve nutrient absorption.*

As a laxative
Magnesium sulfate increases the amount of water in the intestines, thereby encouraging elimination for occasional constipation relief. This product generally produces bowel movements within 30 minutes to 6 hours after use.*

As a liver and gallbladder cleansing aid
Magnesium sulfate relaxes and dilates the gallbladder, allowing the release of hardened deposits. Paired with olive oil, these impurities are expelled from the body. We have Epsom salt in capsules so you no longer have to suffer the bad taste of an Epsom salt solution. Please see Liver Cleanse directions for the Liver Flush.

Before using Magnesium sulfate you can perform a test in order to reduce your anxiety about the liver flush and to assess how you react to magnesium. The test is optional and should be done the week before you do the liver flush. Please see Liver Cleanse directions for how to perform the test.

Suggested Usage
As a saline laxative, adults take up to 15 capsules with at least 8 fl. oz. of water, or as suggested by a healthcare professional. Do not take for longer than 1 week. For occasional constipation, not a chronic condition.

In case of overdose, get medical help or contact Poison Control Center right away.
