A Quick Guide to CBD Oil and Supplement Labels

Introduction To Reading & Understanding CBD Oil Product Labels

First of all, Congratulations on considering CBD oil! CBD oil benefits your body and mind by helping with pain, anxiety, and numerous other ailments. The best part about CBD oil is that it has very little negative side effects and numerous beneficial side effects. CBD oil is also now legal in most states and has a legal level (less than .3%) of THC, therefore it is highly uncommon you will ever fail a drug test after use. 

CBD oil is a new advancement in supplements and because of this, some find it quite difficult to fully understand product labels. No worries, that’s why we at Maku created a quick and easy guide to labels!

Product Source & Third-Party Lab Testing

As soon as you see a bottle of CBD oil you’ll immediately see the brand. This is the first thing you should research. It’s important that you find out the validity of the company, where and how they acquire their hemp, and the methods used to process the bio-mass to oil. An easy way to do so is to find out if they have third-party lab testing, it’s essentially just an unbiased second opinion making sure your product is safe and what it claims to be. 

If the product is lab tested by a third-party, make sure there are no reported pesticides and/or heavy metals. And if the product is not third-party lab tested, steer clear. That’s a BIG red flag. 

Milligrams (mg)

Milligrams are used as a unit to measure the amount of CBD (cannabidiol) in a CBD oil product. The amount of milligrams of CBD in the product directly reflects the concentration of CBD, and therefore, its potency. As you shop around, you’ll notice that the higher the concentration of CBD, the higher the price. Make sure to do your research in order to get the highest quality product, at the lowest price point. 

CBD Oil Tinctures

With regards to tinctures or droppers, easy math will tell you it’s potency. Essentially you take the milligrams and divide it by the milliliters. An example would be Maku’s 2500mg product. The quick math is 2500mg divided by 30ml which results in 83.3mg for 1ml, a very strong product. It also happens that one full dropper is 1ml, so if you take one full dropper you have ingested 83.3mgs of CBD oil. 

CBD Oil Vape Pens

CBD oil vape pens follow the same formula as the oil tinctures. So the mg divided by ml method works for these products as well!

CBD Gummies and Capsules

When looking at the bottle or bag of CBD gummies and capsules, the stated mg can either refer to “per gummy or capsule” or “per bottle”. So you have to take a closer look. Typically, if the number is bigger it’s for the container, however, the container should have it clearly stated whether it’s per gummy or per bottle.


Other Label Information

Full Spectrum or Isolate

This is an easy differentiation and will be clearly placed on the package. If the product says Full Spectrum or whole plant extract, then it contains some THC and other products from the hemp plant. It will contain less than .3% to ensure that it is legal in most states.

CBD isolates do not contain any THC. It is the CBD molecule with MCT (or coconut oil) as a carrier. This product is best for those worried that CBD oil will affect their ability to pass a drug test. 


The product will always state how much THC is in the product or if there is no THC in the product. If the products does not state the THC content, look elsewhere. Remember to read the lab tests! 


There will be a recommended dosage on the bottle, but it’s important to find which dosage works best with your body and lifestyle. If you’re unsure, it’s recommended to ask your doctor about what dose you should take. 

Other Ingredients

Normally other ingredients are labeled on the bottle. However, because of the lack of requirements on CBD labels, some may withhold certain ingredients. It’s important to do a little research on the CBD company in order to find what you’re consuming and what company works for your body and mind.  

FDA Disclosure 

To our knowledge, the only FDA approved pharmaceutical containing CBD is epidiolex, produced by GW pharmaceuticals.  Although dietary supplements do not require FDA approval, the label should have a disclosure reporting that FDA has not evaluated the statements or product.  If the label does not have that disclosure, its not a product you want to buy.
