Medterra Isolate CBD Oils

Medterra Isolate CBD oils are a great price. Their highest potency option — 6000 mg — costs only $0.03 per mg CBD which is incredibly low, even for a CBD isolate.

This is one of the best low-cost CBD oils we’ve found yet. The company behind this product — Medterra — is one of the largest manufacturers in the industry. This gives them the leverage to source the best hemp, and maintain the lowest prices possible. 

The company uses its proprietary broad-spectrum formula for this product — which can be found in most of their other products as well. This formula is a combination of cannabinoids and terpenes mixed together in consistent and predictable ratios. This means each bottle is going to offer a similar level of benefit to a full-spectrum hemp extract while at the same time guaranteeing no THC. 

Price/Value 4/5

If you’re looking for highly concentrated CBD isolates, Medterra may be a good choice. The downside here is that none of these tinctures are full-spectrum.

For those of you looking for CBD isolates, these tinctures pack a lot of value into a 30 or 60 mL bottle.

CBD Potency 5/5

These CBD tinctures are on the mid to high end of the CBD spectrum. If you have high CBD requirements, the 3000 and 6000 mg products pack 100 mg of CBD into each serving.

The lower concentration is pretty solid as well at 16 mg per serving.

Hemp Source 4/5

All of Medterra’s CBD products are made with hemp sourced from the Kentucky Department of Agricultural Industrial Hemp Pilot Program. The hemp is third-party tested and guaranteed to be free from dangerous contaminants. However, the company doesn’t say whether or not its hemp is organic.

Purpose/Uses 4/5

If you need high daily doses of CBD, Medterra is one of the few providers of ultra-high potency CBD oils. In the highest concentrations, Medterra offers up to 100 mg/mL — which should be more than enough for even the most experienced users. 

Product Variations 4/5

These tinctures are available in four concentrations that are far enough apart to be used for different requirements and conditions. Medterrra could improve by offering more sizes or lower concentrations.

Formula/Ingredients 3/5

These tinctures use a basic formula that can be found in many other CBD products on the market.

You’ll only find the following two ingredients: CBD isolate and MCT oil. Medterra would benefit from offering more herbs or ingredients to help CBD achieve its goals more effectively.

Medterra Isolate CBD Oils Review

Editorial Staff , last updated on December 9, 2021

Oils & tinctures provide one of the most common ways of using CBD. As a result, there are hundreds of options for you to choose from.

For those of you just starting your search for CBD, it’s a chemical compound found in cannabis that can potentially treat pain, inflammation, seizures, stress, anxiety, depression, and more.

This review will focus on the Isolate CBD Oil offered by Medterra to help you decide if they’re right for you.

If you’re looking for a simple CBD oil on a budget, Medterra is an excellent choice with CBD oils as cheap as $0.03 per mg of CBD.

Overview: Isolate CBD Oils

Medterra has a solid range of CBD products, including tinctures, capsules, pet oils, and topicals.

All of its CBD products are made using non-GMO industrial hemp grown in Kentucky. Each product has been tested by a third-party lab and is guaranteed to be free from potentially dangerous contaminants.

All Medterra CBD is made using CO2 extraction, which is currently regarded as the gold standard in the industry.

Medterra only uses CBD isolates, which only contain CBD that has been separated from the other chemical compounds found in the cannabis plant.

The main benefit of CBD isolates is that they tend to be less expensive and are THC-free.

Full-spectrum products are those that are made with the entire hemp plant and contain many of these other chemical compounds that can potentially help CBD do its job more effectively.

There is some debate regarding whether full-spectrum or isolates are more effective, but the consensus seems to be that full-spectrum oils are superior.

Medterra offers CBD oils in four different concentrations: 500 mg, 1000 mg, 3000 mg, and 6000 mg. Each bottle contains 30 – 60 mL of product. 

The included dropper has level markings at 0.25 mL, 0.5 mL, 0.75 mL, and 1 mL, which makes it easier to find the right dose for your needs.

Medterra recommends taking 1 mL sublingually (under your tongue) to get the maximum benefit.

The Isolate CBD tinctures can be purchased for $39.99, $55.99, $132.99, and $199.99 depending on your choice of CBD concentration. They all come with a 30-day satisfaction guarantee.

Pros & Cons

Pros Cons
  • High-potency options available
  • Inexpensive source of CBD
  • 30-day satisfaction guarantee
  • Made from CBD isolate

Key Features & Benefits

1. High-Potency

These CBD oils are much more potent than many other options on the market. The lowest concentration is roughly 16 mg of CBD per serving, which is a pretty good dose for those of you just starting.

If you’re after something that packs a punch, there aren’t many competing products available that contain up to 6000 mg of CBD. For this reason, Medterra may be good for more experienced users or people with severe symptoms.

2. Inexpensive

These CBD oils are isolates and, therefore, less expensive than their full-spectrum counterparts. If you need CBD on a budget, these oils provide a low cost per mg of CBD. All of Medterra’s oils are $0.08 or less per mg of CBD.

3. 30-Day Satisfaction Guarantee

If you’re trying Medterra’s products for the first time, you can do so worry-free with the 30-day satisfaction guarantee. If the products don’t work for you or you’re otherwise unsatisfied with your product, you can get your money back within 30 days of receiving your order.

About the Company: Medterra

Who Should Consider Using Isolate CBD Oils?

CBD oils are gaining popularity around the world to help people manage symptoms like pain, inflammation, stiff muscles and joints, anxiety, stress, seizures, and more. Tinctures offer more flexibility than other methods such as capsules, and more precise doses than vape oils. Tinctures are also one of the least expensive ways to get your dose of CBD.

As isolates, Medterra’s oils tend to be on the less expensive side of CBD products. Therefore, if you’re looking for a high-potency CBD oil on a budget, Medterra may be a good choice.


Isolate CBD Oils are some of the more common and concentrated products on the market. As a result, they tend to be less expensive than other CBD products, including capsules, edibles, and topicals. Additionally, Medterra uses CBD isolates, further reducing the cost per mg of CBD.

Therefore, if you’re okay with CBD isolates, these oils provide a lot of value.

Hemp Source

Medterra sources all of its hemp from the Kentucky Department of Agriculture’s Industrial Hemp Pilot Program. The company states that all of its CBD products are guaranteed to be 0% delta 9 THC, non-GMO, and pesticide-free. Medterra also supplies regular third-party test results so you can see exactly what’s going into your body.


If you’re in need of high daily doses of CBD, Medterra offers one of the highest potency options we’ve seen in our research so far. At 100 mg/mL, this oil should be more than enough for even the most experienced CBD users.

It may help manage more severe or chronic symptoms that lower-potency oils can’t.

Product Variations & Flavors

These oils are available in three concentrations. Each concentration is spaced far enough apart from the next to be potentially used for different purposes. However, there aren’t any options regarding flavor or bottle size.


Medterra uses a simple formula that can be found in many other products currently available. The company only includes CBD isolate and MCT oil in its oils. We’d like to see other ingredients or herbs that may help CBD do its job more effectively.

Medterra Shipping & Return Policy

Medterra ships within the United States and internationally. However, Medterra doesn’t currently ship to Canada or Australia. If you’re not satisfied with your products, Medterra offers a 30-day satisfaction guarantee.

Final Verdict: Good Choice for Potent CBD Isolates

Overall, these Isolate CBD oils are fairly standard but are a great value for the price. Medterra’s oils are inexpensive and highly potent if you choose the 3000 mg product.

The main downside to these oils is the fact that Medterra doesn’t offer full-spectrum CBD products. However, this allows Medterra to price its products more competitively and helps to keep products more consistent.

If you’re looking for full-spectrum CBD products, Medterra isn’t the right choice. As we mentioned earlier, there is some evidence to support the notion that full-spectrum oils are more effective.

In conclusion, these oils are great if you need a potent CBD product and are on a tight budget. We always try to recommend full-spectrum CBD products when possible, but Medterra offers some good substitutes.
