About the brand: Who are NuLeaf Naturals?

Since 2014, NuLeaf Naturals have been producing high-potency, full-spectrum CBD oils for both humans and pets. They work with solely organic hemp plants grown in Colorado and irrigated with “pristine Rocky Mountain water.”

NuLeaf is one of a growing number of larger CBD manufacturers who operate on a ‘seed-to-shelf’ basis, meaning that they have input and oversight in the entire production process. This results in an impressively rich full-spectrum product, which contains zero additives.

NuLeaf uses extensive third-party independent testing to ensure product quality, giving consumers confidence that their products really do contain a beneficial mix of cannabinoids and terpenes. Their commitment to product quality has resulted in a large following of owners and their dogs, with over 20,000 highly rated customer reviews and counting.

Best NuLeaf Naturals CBD oils and treats for dogs

  • NuLeaf Naturals only uses organic hemp to make their products, which is produced in Colorado and closely monitored by the brand on a ‘seed-to-shelf’ basis.
  • To extract cannabis compounds from the hemp plant, NuLeaf uses industry-leading subcritical and supercritical CO2 extraction, which retains the integrity of compounds and meets strict food-safety requirements (and residual carbonation is completely harmless).
  • NuLeaf Naturals uses organic virgin hemp seed oil as a carrier for their CBD. We love hemp seed carriers, as the oil pairs naturally with CBD and is rich in beneficial fatty acids and antioxidants.

Cost per milligram of CBD

NuLeaf Naturals CBD oil is formulated in three different concentrations: 300mg, 900mg, and 1800mg, which gives owners an extra level of control when it comes to achieving the correct dosage.

NuLeaf has chosen relatively high concentrations of CBD for each option (it’s not uncommon to see 100-200mg strengths for small dog products), which we think is a great decision. This ensures that pups will absorb a substantial amount of CBD, making beneficial effects more likely, while still remaining appropriate for their size and weight.

Another impressive aspect of these CBD oils is their value for money. NuLeaf offers highly competitive pricing across all three oil strengths, and keeps the cost per mg of CBD relatively equal in each formula—something that only a minority of brands can claim. At 13 cents per mg, the 300mg CBD formula is good value, while the 1800mg option ranks among the most wallet-friendly full spectrum CBD oils around, at just 1 cent.

Spectrum and carrier oil

In CBD oils, ‘spectrum’ refers to the diversity of cannabis compounds extracted from hemp and contained in the oil. While CBD isolates should only contain cannabidiol (CBD), broad spectrum oils will contain CBD plus several of the other hundred-odd cannabinoids found within the plant.

Full spectrum oils include a full extraction of the hemp plant, which means that a CBD oil will contain some amount of every cannabinoid, flavonoid, and aromatic terpenes present in the plant. To get the right mix of ingredients, suppliers of full-spectrum oils therefore need to choose their hemp strains carefully.

Beyond CBD, NuLeaf’s full spectrum oil contains the secondary cannabinoids CBC, CBG, CBDV, and CBN. Each of these compounds possesses its own similar anti-inflammatory properties and is thought to increase the potency of CBD through something called the Entourage Effect. This is a name given to the observation that full spectrum oils have a greater relative impact on the body than isolates.

What are customers saying?

Out of all the CBD brands we’ve reviewed (and that’s a lot!) only a few can boast more positive feedback and owner testimonials than Nuleaf Naturals.

Many of the most enthusiastic reviews come from owners of senior pups, many of whom suffer from mobility and joint health issues. One owner of a 10-year-old dog experiencing pain, even while taking anti-inflammatories, found it easier to move around after taking CBD: “stairs and getting into the car doesn’t seem to be a problem for her anymore.”

Others have been using NuLeaf CBD as a complement or alternative to traditional vet-prescribed medication. One owner commented that their pup achieved more restful sleep, was moving around better, and got their appetite back after supplementing with CBD.

Our verdict

NuLeaf Naturals produces a CBD oil with a potent, if narrow range of additional cannabinoids and terpenes, which all help to enhance the effectiveness of the product. We love the attention to detail that NuLeaf gives to the sourcing and production of their CBD oil, which is what allows them to offer such a rich-spectrum product that’s received thousands of positive reviews from owners.

On top of their superior quality, NuLeaf Naturals provide awesome value for money, with their very highest concentration option coming in at just 1 cent per mg of CBD. The only real downside we can find is that dogs are restricted to oil, as NuLeaf doesn’t offer any CBD snack or balm options.
