We take great pride in providing you with supplements designed to help support the vital systems in your body.
With this in mind, it’s only natural that we go through rigorous testing and verification to ensure that every supplement contains what is claimed on the ingredient list.
This ensures that you, the customer, are getting exactly what you need.
To that end, let’s talk a little bit about the supplement process and how we end up with the supplements you see available on our website.
Here’s what this page covers:
- The formulation process
- The manufacturing process
- FDA-registered, NSF GMP-certified facility
- Third-party tested and verified
- Fillers and binders
The formulation process
Before our supplements are manufactured, they are created with you in mind.
I spend a lot of time researching and learning about ingredients, vitamins, and botanicals to find the combinations that are most likely to provide you with the results you are looking for.
The manufacturing process involves much more than just picking random vitamins and botanicals and throwing them together.
Finding ingredients that work synergistically with one another, using blends of ingredients at the right ratios, and using ingredients at the right doses are all important, and all make a difference.
Once I have my ideas formulated, I then go about testing and refining them.
The supplements you see on my website right now are the result of hours of research and testing.
These supplements have been refined over the years to focus on the exact problems that thyroid patients face and contain the ingredients these patients need to see results.
You can read more about this process on my supplement creation process page.
The manufacturing process
Formulating a supplement is only the beginning because the manufacturing process involves so much more.
Even though two supplement companies can start with the same formula, the end product can vary dramatically depending on ingredient sourcing, facility standards, and quality control at every step.
Manufacturing the right supplement is all about doing everything right at every single step.
And that’s what I try to do when manufacturing my supplements.
From the source of the ingredients to the bottles being used to the inactive binders and fillers, each of these plays a role in the end result.
This isn’t all, though; it’s just the creative process.
From there, my supplements undergo a battery of tests to ensure quality and purity.
Manufactured in an FDA-Registered, NSF GMP-Certified Facility in the United States
All of my supplements are produced and manufactured in an FDA-registered facility that is GMP-certified by NSF International (NSF/ANSI 455-2) in the United States.
GMP stands for Good Manufacturing Practice and is the baseline standard that supplement companies must follow to sell products in the United States. Our facility goes further by holding third-party GMP certification from NSF International, one of the most respected independent certification organizations in the world.
Our manufacturing facility is GMP-certified by NSF International (NSF/ANSI 455-2), meaning it is independently audited to meet rigorous standards that eliminate or reduce contamination, manufacturing errors, and mix-ups.
This third-party NSF GMP certification, combined with our FDA-registered facility status, ensures that you get a stable, safe, and consistently high-quality product.
Even though all of my supplements are manufactured in the United States, it does not mean that all ingredients come from local areas.
We get a lot of questions about the source of our ingredients.
Whenever possible, I try to get raw ingredients from the United States, but that’s not possible in every situation.
Some botanical ingredients, such as guggulsterone, are found in other countries and must be imported.
Our manufacturers take steps to ensure that all ingredients, even those that come from other countries, undergo testing prior to encapsulation.
Third-Party Tested and Verified
To ensure purity, all of my supplements undergo what is called third-party testing.
Even though every raw ingredient is tested prior to being used for content and purity, I spend extra money to send samples to a third-party source to verify.
Third-party laboratories test samples of each lot for:
- Arsenic
- Cadmium
- Lead
- Mercury
- Yeast count
- Mold count
- E. coli
- Salmonella species
- Staphylococcus aureus
- Enterobacteriaceae
- Clostridium spp
The result is that every single lot is tested at least twice.
All third-party testing is performed by ISO-accredited laboratories, which means the labs themselves are independently verified for competence and accuracy.
This process of testing and retesting means you don’t have to worry about taking something that is harmful or filled with contaminants.
It means that when you take my supplements, you know that you are getting the ingredients stated on the label without anything extra.
You can view downloadable third-party test results for every product on our third-party test results page. You can also email us at hello@restartmed.com to request the test results for any specific lot number.
Fillers and Binders
You’ve probably heard a lot about fillers and binders.
When supplements are created, they usually have some amount of inactive binders.
These binders can help with the manufacturing process, assist with absorption, and stabilize the ingredients.
Without these ingredients, you may actually get a worse product.
Having said that, it’s always ideal to use as few inactive ingredients as possible.
Why?
These ingredients can be the source of problems for some people.
I take several steps to combat this problem:
#1. I only use naturally occurring inactive fillers and binders.
Sometimes using binders is necessary, and when it is, there’s a big difference between using something that is synthetic and something that comes from nature.
I opt to use naturally occurring binders that come from sources such as plants, vegetable sources, and non-GMO sources.
The most common inactive ingredients across my product line include:
- Hypromellose – This is the capsule itself. It’s a plant-based alternative to gelatin capsules, making it suitable for vegetarians and those who avoid animal-derived products. Why we use it: because it’s the cleanest alternative, and it’s safe for those with alpha-gal syndrome or in those who want to avoid animal-based gelatin.
- Microcrystalline cellulose – This is a plant-derived fiber used as a flow agent during encapsulation. It ensures that the active ingredients move smoothly through the machinery so each capsule gets a consistent, accurate dose. Why we use it: because several of our formulas, such as Essential T2, require precise dosing in every capsule. Without MCC, our dosing wouldn’t be accurate.
- Vegetable magnesium stearate – This is a plant-sourced lubricant that prevents ingredients from sticking to the encapsulation equipment. Without it, capsules can end up with uneven ingredient distribution. Why we use it: many of our formulas use multiple powders with different densities. Without mag stearate, they separate during the encapsulation process.
- Silicon dioxide – This is a naturally occurring mineral used as an anti-caking agent. It keeps powdered ingredients from clumping together, which ensures uniform mixing and consistent potency across every capsule. Why we use it: many of our formulas use high doses of botanical ingredients that are “sticky” or “wet” powders. Without silicon dioxide, the powder clumps up and sticks to other ingredients.
This ensures that even when they are necessary, they are as inert as possible.
What does this mean for you?
It means for all intents and purposes that you won’t even notice that they are there, and they won’t impact how well my supplements are working in the body.
#2. I only use the minimum amount possible in supplements and avoid them when possible.
My first goal is to try to avoid them whenever possible, but when that isn’t possible, I opt to use as few as possible.
This sometimes means playing around with math, adjusting the size of capsules, and making changes to the ingredient profiles.
Doing this allows for each capsule to maintain as many active vitamins, botanicals, and minerals as possible while minimizing any extra space inside each capsule.
Again, the result is a better product for you.
