CBD & Hemp Extract FAQs

1. What is the difference between Certified THC-Free, Full-Spectrum Hemp Extract, and CBD Isolate?

Oxygen Nutrition sells two types of products: Full Spectrum Hemp/CBD Extract and Certified THC-Free Hemp/CBD Extract. We do not sell anything that contains CBD isolate. Every single product in our CBD line provides the benefits of whole plant cannabinoids, also known as the entourage effect.

Here are the main differences between our products:


Full Spectrum

CBD Isolate

Does Oxygen Nutrition produce or use this type of hemp extract?



Oxygen Nutrition does not use CBD Isolate in any of our products

Do Oxygen Nutrition products contain THC?

0.00% THC

Less than .3% THC


Extraction Method

Low-temperature CryoPress + Liquid Chromatography

Low-temperature CryoPress



Certified THC-Free 

Oxygen Nutrition’s Certified THC-Free Hemp Extract products contain less than 0.00% THC. Each batch undergoes rigorous extraction and third-party testing methods to verify this. 

Full-Spectrum Hemp Extract

Oxygen Nutritions’s Full Spectrum Hemp Extract  is processed using low-temperature CryoPress with food grade ethanol. This process keeps cannabinoids, terpenes, chlorophyll, and many other naturally occurring compounds intact. 

While our Full-Spectrum Hemp Extracts contain trace amounts of THC, all of Oxygen Nutrition’s products contain less than 0.3% THC – strictly adhering to the standards set forth in the Federally Approved 2018 Farm Bill.

CBD Isolate

CBD Isolate is made by refining and isolating just one of hundreds of cannabinoids: CBD. This process strips out 100+ beneficial cannabinoids, terpenes, and many other compounds naturally found in the hemp plant. This produces a white powder that contains 99% CBD. Oxygen Nutrition never uses CBD isolate in any of our products. 


2. What is the Difference Between Hemp-derived CBD and THC, and How Does It Impact My Mind and Body?

In order to understand the difference between CBD and THC, you first need to understand the difference between hemp and marijuana. Although the two are often mixed up with each other, hemp and marijuana are very different.  

Hemp plants look very similar to marijuana but are bred to contain very little THC. Unlike marijuana plants, hemp plants are naturally rich in CBD and many other phytocannabinoids. The name “CBD” is actually an abbreviation; it’s short for cannabidiol, a naturally occurring compound with powerful wellness benefits. A plant-derived oil, CBD, comes from the hemp plant, a flowering herb indigenous to Central Asia. All of Oxygen Nutrition’s high-quality wellness products are made exclusively from hemp-derived CBD. Nutrient-packed and therapeutic, hemp-derived CBD may help balance your immune system, support chronic pain management, help sore muscles, aid in skin and lip protection, and more without any of the unwanted effects of marijuana.*  

The marijuana strain of cannabis has been intensely cultivated in order to enhance its concentration of delta-9 tetrahydrocannabinol, or THC, the compound that generates the mental and physical effects that marijuana is known for. 

Oxygen Nutrition’s THC-Free Hemp Extract is 100% hemp-derived and contains 0.00% THC. Our Full-Spectrum Hemp Extracts are also 100% hemp-derived, contain less than 0.3% THC and strictly adhere to the standards set forth by the Federally Approved 2018 Farm Bill.


3. What Extraction Methods does Oxygen Nutrition Use? What Should I Keep in Mind When Looking into CBD Extraction Methods?

Oxygen Nutrition uses two different extraction methods: One for Full-Spectrum Hemp Extract and the other for our Certified THC-Free extracts. 

Our Full-Spectrum extraction process utilizes low-temperature CryoPress with food grade ethanol to derive full-spectrum hemp extract from industrial, U.S.-grown hemp. Oxygen Nutrition’s CryoPress extraction process ensures that our hemp extract retains its nourishing omega fatty acids, terpenes, and other therapeutic elements found naturally in the hemp plant.

Oxygen Nutrition’s Certified THC-Free Extract undergoes a unique two-step method, combining the CryoPress with Liquid Chromatography extraction. This is the most advanced way to effectively remove THC, while preserving beneficial terpenes and cannabinoids like Cannabigerol (CBG), Cannabichromene (CBC) and Cannabinol (CBN). The resulting product may also be referred to as broad spectrum hemp extract.

With both processes, your mind and body benefit from a blend of the following naturally occurring compounds found in hemp,

  • Cannabinoids, beneficial natural compounds that help support your physical and mental wellbeing*
  • Terpenes, the aromatic “helpers” which maximize cannabinoids’ effectiveness. These may help your body operate at peak performance*
  • Flavonoids, potent plant-based antioxidants which help with inflammation and support heart health* 
  • Omega Fatty Acids, crucial nutrients that combat depression and ADHD, aid circulation and support chronic pain management*
  • Amino Acids, the body’s building blocks, which help you to stay energetic, add muscle, sleep soundly, keep fit, and focus on what matters to you

While Oxygen Nutrition's extraction processes are more thorough than most, CBD products are not regulated by the FDA. Therefore, we recommend that consumers carefully research any CBD products they’re interested in before purchasing them. 

Be wary of companies that make exaggerated promises about the amount of CBD in their products. The truth is, the various processes used in the industry yield differing concentrations of CBD. An extraction process that involves using butane or acetone as a solvent is also a red flag.

CBD may help you manage chronic pain, boost your immune system, decrease anxiety, and replenish your energy levelsbut only if it comes from a high-quality source like Oxygen Nutrition.* 


4. How Does Oxygen Nutrition Test Its Products? Are Test Results Available for the Public to View?

Oxygen Nutrition’s premium-grade CBD products are tested using the gold standard in our industry: third-party testing. To ensure the integrity of our products, each batch is reviewed by an independent lab not affiliated with our company. 

We’re proud of the purity of our products, so we make this testing process fully transparent. After the third-party lab has analyzed our batches, each one is given a Certificate of Analysis (COA), which is stored in our publicly accessible Oxygen Nutrition's batch database.

When you buy a Oxygen Nutrition Certified THC-free or Full Spectrum CBD product, we provide the lot number, so you can look up its COA for yourself. As you’ll see, Oxygen Nutrition’s CBD/hemp extract products are:

  • Rich in CBD, cannabinoids, and terpenes
  • Extracted to preserve Full-Spectrum benefits
  • Available in Certified THC-free options
  • Free of contaminants like pesticides, heavy metals, microbials, residual solvents, and mycotoxins
