Allergen and Ingredient Information

What allergens are your products free of?

Gaia Herbs products do not contain gluten, dairy, meat, peanuts, sesame, shellfish, yeast or eggs.

Do your products contain tree nuts?

Gaia Herbs processes fresh Black Walnuts in our facility. They are found in the Black Walnut Fresh Green Hulls Liquid Herbal Extract and Wormwood Black Walnut Supreme Liquid Herbal Extract. All equipment is cleaned between manufacturing lots per GMP requirements.

Products made by Aboca for Gaia Herbs do not contain any tree nuts. Tree nuts are not used in Aboca’s facility.

Are any of your products vegan or vegetarian?

Most of our products are vegan; all Gaia products are vegetarian. The following Gaia Herbs products are not vegan because they contain honey or other bee-derived ingredients:

Bronchial Wellness Herbal Syrup

Echinacea Goldenseal

Propolis Throat Spray

Echinacea Goldenseal Supreme

GaiaKids Black Elderberry Syrup

GaiaKids Bronchial Wellness for Kids

PlantForce™ Liquid Iron

Propolis Extract

Vitex Elixir for Women

Are your products free from corn?

The L-Tyrosine in Thyroid Support is derived from non-GMO corn. The citric acid in PlantForce Liquid Iron is derived from corn (glucose). There are trace amounts of corn in Eleuthero root, Mental Alertness, Energy Vitality, Gingko Gotu Kola, Elderberry capsules, Immune Shine, Turmeric Boost Restore, Turmeric Boost Uplift and Throat Shield Lozenges and Spray and Sleep and Relax Tea. No other products contain corn-derived ingredients. As of May 2019 Vitamin C, listed on the label, (derived from corn), was removed from Vision Enhancement and is no longer listed on the label. The xanthan gum that is used in our products is produced by bacterial fermentation.

As of May 2015, we use 190-proof non-GMO sugar cane alcohol for all products extracted at our facility in Brevard, North Carolina. Those new labels list “alcohol USP” or “organic alcohol USP.”

For products made before then, we used 190-proof alcohol derived from corn and wheat. The alcohol used for extraction is distilled and certified gluten-free by the manufacturer. The distillation process eliminates proteins (gluten is a protein).

Are your products soy-free?

As of 2016, Gaia Herbs products are soy-free. In 2015, Gaia transitioned to non-GMO sunflower lecithin. This exclusively replaced our previous lecithin, sourced from non-GMO soy (labeled as non-GMO soy lecithin). The new labels read “lecithin” to allow flexibility to use a different type of non-soy/non-GMO lecithin in the future.

Are Gaia Herbs products gluten free?

Gaia Herbs does not use any gluten containing ingredients in our products. Our products are tested annually for gluten by a third-party lab using the ELISA test method for gluten, with a detection limit of 5 ppm. All of our products have tested below the federal limit of 20ppm gluten for a ‘gluten free’ claim, with the exception of Milk Thistle Seed liquid alcohol extract (not the Milk Thistle capsules) and Gas & Bloating tablets.

We use oat seed (Avena sativa) picked during the milky stage of growth (called Oats Milky Seed) in a few of our products. Our oats are processed within 48 hours of harvest and are not cross contaminated with any gluten containing grains and have tested gluten free. Oats are a gluten free grain unless cross contaminated with other grains that contain gluten, however, some very sensitive people avoid even gluten free oats.

Please contact info@gaiaherbs.com for further info about gluten testing in our products.

What is the source of your alcohol?

As of May 2015, we use 190-proof non-GMO sugar cane alcohol for all products extracted at our facility in Brevard, North Carolina. Those new labels list “alcohol USP” or “organic alcohol USP.”

For products made before then, we used 190-proof alcohol derived from corn and wheat. The alcohol used for extraction is distilled and certified gluten-free by the manufacturer. The distillation process eliminates proteins (gluten is a protein).

What is the source of your glycerin?

Gaia Herbs’ glycerin is derived from a blend of non GMO rape seed oil (also known as canola oil), non GMO sunflower oil, and sustainably certified non GMO palm oil. Glycerin is a distilled product and therefore does not contain any protein derived allergens.

What are the ingredients in your Liquid Phyto-Caps®?

Gaia Herbs hypromellose capsules are the same vegan and gluten-free Liquid Phyto-Caps® that we have always used. With recent labels we have changed the wording on the label to be more accurate with labelling requirements. Other companies are also following suit, and you will see this occurring on many more product labels in the upcoming year. Gaia’s cellulose capsules are made from HPMC (Hydroxypropyl methylcellulose, also known as hypromellose), which is derived from cellulose from pine trees. Hypromellose is semi-synthetic, meaning that the ingredients are naturally derived, but there is a processing step in the lab to break down the cellulose and rebuild it. The capsules have passed third party testing for residual solvents according to USP guidelines. Some grades of HPMC do have polymer plasticizers mixed in, however Gaia Herbs has chosen a capsule which contains only the cellulose from pine trees mixed with water. There is no danger of phthalate consumption with Gaia Herbs capsules.

What are your other capsules made of?

Some of our capsules are made from pullulan. This is derived from naturally fermented tapioca. Pullulan capsules are also vegan and gluten-free.

Purity, Integrity, and Potency

Does Gaia Have 3rd Party Testing?

Third party testing is used by Gaia Herbs on an as needed basis, however, most of our testing is done in house because of the sophisticated equipment and knowledge needed to test our products. Our lab has also been audited by a third-party lab to ensure the scientific validity of our instruments and methods and received a 100% score. Gaia’s products are not USP or NSF certified; their test methods are not usually directed towards the testing of full spectrum herbal products. We have established specifications, many of which can be seen online. We post these results online as well as the test methods that we follow (on the Certificate of Analysis through Meet Your Herbs. Gaia Herbs is registered by the FDA and was audited by the FDA in Dec 2011, August of 2014 and June of 2017.

Where is Gaia’s Turmeric Sourced and Is It Tested for Lead?

The recent concern regarding lead contamination in turmeric seems to be based in turmeric being sold in Bangladesh that has been intentionally adulterated with lead chromate to enhance the color. We test all incoming materials for heavy metals including lead, mercury, cadmium, and arsenic, and our turmeric is primarily sourced from Indonesia and India. You can check sourcing and testing info for each particular batch of product by scrolling to the bottom of any product page to view the results of the latest batch of product or entering the Meet Your Herbs ID # printed on the bottle at Meet Your Herbs.

Gaia Herbs uses ICP-MS to test for arsenic, mercury, cadmium and lead. ICP-MS stands for Inductively Coupled Plasma Mass Spectrometry. This instrument is the centerpiece of Gaia’s heavy metals testing. This powerful technique is capable of observing a wide range of metal at quantities as low as a nanogram of metal in a gram sample. The ICP-MS allows Gaia to obtain precise and sensitive data for all materials in a high speed manner. The plasma vaporizes the sample and ultimately breaks it down to the atomic level. The mass spectrometer is then able to detect all atoms of interest.

How does Gaia Herbs test for pesticides?

Gaia tests for purity using an analytical method called Gas Chromatography-Tandem Mass Spectrometry, or GC-MSMS. This testing is used to check all raw herbs for pesticides. Read more about this with Meet Your Herbs.
