Learn About Our Ingredients

Ingredients Matter.

We are what we eat. We know that if we consume the right nutrients, we feel better. We understand that vibrant, healthy lives require the ability to create new healthy cells.


Every ingredient is carefully curated.

At Tennant Products we take great pride in ensuring our products contain the purest ingredients on the planet in their most bioavailable form. It is critical that each ingredient is sourced, tested for identity and microbiology, stored appropriately and cared for throughout the manufacturing process with the utmost care. We go to great lengths to ensure that each ingredient is in its natural form so it can be used by the body without additional stress, waste or extra energy exerted.


Only the Best

No GMOs, fillers, sugars, artificial flavors or toxic excipients are used in any of our products. All products are manufactured in the USA. At Tennant Products, we also trace back each of our ingredients to the original source to ensure there are no additional toxins or ingredients added along the way.



We also ensure that the ingredients provided are in the most bioavailable form, or “methylated form.” Methylation is a process that happens in our bodies millions of times daily. This is a process where nutrients are broken down into forms the body can use. There are many steps in this process, and often times each step contains many sequences to get from point A to point B. Studies have shown us that more than 40% of the population have issues with this process of converting nutrients, so we go the extra mile to ensure the ingredients we provide are each in their most usable form for your body regardless of how well you methylate.


“Fast Pass” for Methylation

An example of this is Vitamin B3. Niacin or Niacinamide is often used as part of the Vitamin B-Complex. Niacin actually has to go through several steps to convert into NADH, the form our bodies use for energy. Tennant Products is giving you NADH instead of the Niacin as this is the form our bodies use, and it can be immediately put to use.  Removing the additional steps our bodies complete millions of times throughout the day is like receiving a “Fast Pass” at Disneyland where you simply skip the line and show up for the ride without having to wait in line.


This approach ensures the body will use the nutrients provided in Tennant Products’ formulas, because they are not only in the most pure and natural form but also are ready for immediate absorption.


Backed by Science

The nutritional world is ever-changing and evolving. Scientists are publishing new studies about how nutrition is evolving, and new research is constantly being updated. Tennant Products is following these studies and trends, backed by science, to ensure we are able to provide the best products backed by science and published research.


One example of this is a change we made in our Vitamin E. Initially, Dr. Tennant’s® Restore Professional used mixed tocopherols as they were thought to have the best overall bioavailability. Then several studies were published about tocotrienols and their improved bioavailability in the body. After additional research, Tennant Products made the switch from mixed tocopherols to DeltaGold® Tocotrienols as the studies showed significantly improved bioavailability for Vitamin E; and we were able to trace the DeltaGold® Tocotrienols to the source, ensuring no potential GMOs or toxins would be involved. Yes, this ingredient costs a little more, but wouldn’t you rather know the origin of what you consume and have the easiest form for your body to use?
