Lab Results


CBD is a new and developing market in need of conscious companies driving it on the right path. Voice of Nature vision is to improve general wellbeing providing CBD products that you can rely on. 

We believe that virtue lies in the middle. 

This belief led us to create¬†broad-spectrum hemp oils. It’s the ideal option because you get all benefits of a full-spectrum oil without the THC, whilst experiencing the desired “entourage effect” that a CBD isolate lacks.¬†

Broad-spectrum THC free oils are the perfect choice for everyone, especially for athletes and professionals who undergo regular drug tests.

At VoN we provide two independent COA (certificate of analysis) for our CBD oils which guarantees:

  • CBD strength.
  • Safety.
  • Legality.

Since¬†transparency¬†and¬†awareness¬†are part of our core values, you will find all products COAs with ease at this page’s bottom. You can also find a QR code in our products back labels that will redirect you to the certificates.

Below, you will find a full explanation of how to read and interpret lab reports, which is vital to make an informed decision when checking CBD oils. 


Understanding the COA


All sections in a COA are really important, let’s go through them in detail.




The first thing to look at here is the lab name. This a crucial check to be sure the company you are buying from has the test done by an independent laboratory.

In this section, you’ll also find company and product details. Usually, you can see, the customer (i.e. Voice of Nature), product description, condition and batch number.¬†

The last item you should see is the test method, in most cases, it’s the HPLC-DAD, which stands for high-performance liquid chromatography with a diode-array detector. It’s the most accurate method a laboratory can use to separate, identify, and quantify each product component.



Cannabinoids profile


This is the juiciest point and what most people are interested in, the cannabinoids concentration of the products, particularly CBD. 

First, let’s explain a couple of concepts and terms that you may find across, and we want you to be familiar with:

Analyte: is the tested substance, the cannabinoids.

LOQ (limit of Quantification):¬†the lowest concentration at which the cannabinoid (analyte) can be detected. If you see “<” or “N/A” on the analyte result, it means that there isn’t enough to be detected.

Mg/ml: it shows how much of the cannabinoid you will find per millilitre of the product. If the oil is in a 10 ml container, multiply the amount of mg/ml shown in the COA times 10 to determine how much cannabinoid is in the bottle. 



99.5mg/ml x 10ml container = 995 mg of substance in the container.


¬†% w/w- Stands for “weight per weigh percentage”. It is the percentage of cannabinoid per product. For example, a 5 %w/w of CBD means that product is of a 5% CBD concentration.

The measurement of uncertainty: it’s a fundamental concept to understand when you read a COA alone, or you compare two different COA results of the same oil.

The measurement of uncertainty is the expected and accepted level of error for the cannabinoids measurement taken; this always happens in any measure and depends on factors such as calibration. 

Why are we telling you about this? 

Because all CBD oils¬†cannabinoids levels found on the COA aren’t exact but very close to what it says on their label. It comes down to this concept and it’s why we double test our oils; To ensure potency and reliability.




We hope you enjoyed the reading, and it helped you to have a better understanding of the laboratory certificates.

VoN is here to improve general wellbeing; as such, we advocate for quality products that respect our planet. 

We double test our oils to meet our high standards and bring to the market the best quality products that are precise, safe and legal.
