All of the products are made here in the USA.

Tennant Products was designed for adult consumption, however some products are suitable for children. Please consult your physician or your childā€™s pediatrician before using any of our supplements.

Tennant Products provides a ā€œBest Byā€ or ā€œExpirationā€ date which is usually found stamped on the bottom of a bottle or container. This date is the date that we guarantee the potency, freshness and/or quality of that particular product if stored correctly.

A Suggested Use is provided on each of our supplement labels. Your healthcare practitioner may have specific protocols for the products that are uniquely suitable for you.

The list of products that do not contain any animal based ingredients are:

All Oils, Essential and Bioterminal
Activated Bamboo Charcoal
Adrenaline Support Formula
Brain Food, and Plus
Fulvic Super-Concentrate
Fungal Detox
Herbal Voltage
Lugolā€™s Iodine, caps and liquidĀ 
N1O1 Nitric Oxide Lozenges
Raw Materials, caps and liquid

Most of our products are vegan. The following products contain an ingredient or ingredients from animals:

Adrenal Desiccated GlandularĀ - Contains bovine adrenal

Digestive Enzyme FormulaĀ - Contains porcine and bovine animal-based ingredients.

Microbiome Support FormulaĀ - Contains bovine colostrum.

Restore Professional Whey Formula, Chocolate, Strawberry and VanillaĀ - Contains bovine colostrum and whey, as well as a product thatā€™s derived from beeswax.

Restore Professional Veggie Formula and Restore Veggie (non-pro) FormulaĀ - Contain a product thatā€™s derived from beeswax.

Some essential oils are suitable for internal use with proper guidance from a healthcare or medical practitioner.

Those oils are:
Germ DefenseĀ 
Helichrysum Blend
Liver Detox Tea

Yes, all our essential oils are certified organic. Free from herbicides, fungicides and pesticides.

We recommend applying the oils to the concerned areas and avoiding any contact with the eyes, mucous membranes or sensitive areas.

You can take Dr. Tennantā€™s Lugolā€™s Iodine Liquid or Dr. Tennantā€™s Lugolā€™s Iodine Plus Capsules at any time during the day, so long as it is not taken at the same time as medication, probiotics, or beneficial live cultures as the iodine will likely counteract and can make them ineffective. It is recommended to allow two hours between taking iodine and medications or probiotics.

Yes you can, although it is more beneficial to let the tablet dissolve in your mouth. We also advise that you not swallow the tablet whole as this could become a choking hazard.


We cannot recommend storing in the freezer as we have not tested this method of storage. In theory, it should not denature any of the ingredients as long as there is no moisture or liquid to freeze. Most importantly keep Dr. Tennantā€™s Restore away from heat and moisture.

We do not recommend this as the high temperatures may break down or denature some of the ingredients. Although we have been told that some customers put it in their oatmeal for breakfast which sounds interesting, we havenā€™t tried it yet so we cannot say if it actually tastes good that way.

The suggested use is once a day, but many customers can still see benefits from either a half serving a day or one serving every other day.

All forms of restore contain some beeswax and cannot be considered vegan. Our veggie protein formulas are considered vegetarian and not vegan for this reason.

No, Restore uses organic monk fruit extract as the natural sweetening ingredient.

Both formulas are robust and comprehensive for daily vitamin and mineral nutrition. All formulas contain 22g of protein, but the non-professional formula is made with our veggie protein only, does not contain dairy or hormones such as pregnenolone or SAMe, and has a few ingredients with slightly lower quantities. The non-professional formula was designed for the entire family from young children to seniors. As well as for individuals taking hormone medications.
