From Soil to Supplement

Step 1

It all begins with the soil

We believe healthy plants start in healthy soil. To obtain maximum potency from an herb, we plant seeds in micronutrient dense soil sustained by regenerative agricultural practices.

Step 2

Nurture & observe each plant

We allow our herbs to flourish until the right moment to harvest to ensure the purity and potency of each plant. We conduct pre-harvest testing in our on-site laboratory to ensure each ingredient is harvested at peak potency.

Step 3

Extract the whole-plant

Every herb is carefully extracted, without harsh solvents or chemicals, to preserve its beneficial properties.

Step 4

Test for purity & potency

Each product is tested for microbes and heavy metals in our on-site ISO Certified laboratory. When we’re confident each batch is made to a Gaia Herbs standard, they are bottled in our on-site manufacturing facility & sent to you.

Your Questions, Answered

Why is TrustScore flagging Pullulan (or Organic Pullulan)?

Our powder filled caps use pullulan caps. Pullulan is a plant-based polysaccharide (a type of carbohydrate) made by fermenting tapioca starch with a yeast-like microorganism. These caps allow us to have a certified organic capsule. Pullulan capsules are also vegan and gluten-free.

Are your products Organic?

Gaia Herbs purchases Certified Organic ingredients when possible. If not Certified Organic, they are Ecologically Harvested. Ecologically Harvested herbs include herbs that are harvested in their natural habitat, (i.e., wild harvested) according to specific guidelines for harvesting these herbs (i.e., away from roads and industry, as well as guidelines to avoid overharvesting).

All Ecologically Harvested herbs must pass pesticide, heavy metals, and microbial testing prior to being used in our products.

Do you test for pesticides?

Yes. Gaia tests for purity using an analytical method called Gas Chromatography-Tandem Mass Spectrometry, or GC-MSMS. This testing is used in our extensive pesticide testing program when testing our raw herbs.

What is your policy on GMOs?

Gaia Herbs is committed to using and supporting only non-GMO materials. Gaia does not purchase GMO herbs and/or ingredients. We do a purchasing review to ensure we eliminate the possibility of hidden GMOs making their way into our products.

All herbs propagated and grown on Gaia Farm are Certified Organic and therefore are GMO-free. Our seeds, whether sourced from our farm or a trusted supplier, are also GMO-free. We will always do everything possible to ensure that our products are non-GMO.

Do you test for Heavy Metals?

Yes. 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.

What if this product doesn’t work for me?

We stand behind our products and if you are not 100% in love with a Gaia Herbs product purchased from us we will promptly issue a refund. You can request a refund up to 45 days from the ship date from Gaia Herbs. Please visit our Satisfaction Guarantee for the full policy and information on starting a return.
