Recommended for Optimizing Wellness
NuLeaf Naturals recommends its hemp-derived CBD products for those who want to experience the full therapeutic benefits of the synergy of cannabinoids and terpenes in a full spectrum CBD oil.
However, the CBD extracts contain no additives, and pure hemp has a naturally grassy or earthy taste, which first-time users may not find very appealing or flavorsome.
To mask the slightly bitter taste, you can include a few drops of the CBD oil tincture in their food and drinks.

- NuLeaf Naturals Full Spectrum Pet CBD Oil, High-Grade Hemp Extract (60mg/ml)

CBD Concentration per serving range
Based on the certificate of analysis (COA) dated Sept. 9, 2020, 0.5fl oz (15ml) of NuLeaf Naturals full-spectrum CBD hemp oil contains 900mg of CBD. In this 0.5fl oz bottle, approximately 1 drop = 2.4mg of CBD. There are approximately 300 drops total in this 15ml tincture.
Potency – CBD per Bottle
One can determine the CBD potency by evaluating the concentrations of each cannabinoid present in the sample. The potency can be computed by measuring the concentration of cannabinoids present in total percentage by weight (mass).
COA results posted on NuLeaf Naturals’ website are by batch, which means you need to enter the batch number of your purchased product to view its lab report.
On the first page of the COA, the weight indicates the percentage of cannabinoid present in the overall product. Concentration is the amount of cannabinoid broken down into milligrams per gram for reference.
The lab tests report the concentration of a cannabinoid in milligrams per gram of the product. The “Result (mg/ml)” or “Result (mg/g)” columns in the COA contain the tested CBD oil potency. You must compare these results with the CBD concentrations advertised on the product label.
For the 15ml bottle, which contains 900mg of CBD, the potency can be computed by
dividing 900 (mg of CBD in one unit) by 15 ml (quantity in one bottle). Thus, for this example, the potency is approximately 60mg/ml, which closely matches the COA’s report of 62.42mg/ml.
THC Range of Products (less than 0.3% – non-psychoactive)
For NuLeaf Naturals full-spectrum CBD hemp oil, which contains 900mg of CBD, max THC is 0.13% or 1.17mg/ml. This THC level makes the product legal in the US.
Meanwhile, max CBD is 6.78% or 62.42mg/ml.
NuLeaf Naturals tinctures contain no additives or flavorings.
Lab Testing Availability

More About NuLeaf Naturals
Based in Colorado, USA, NuLeaf Naturals is one of America’s top pioneering hemp companies. Plant medicine experts founded the company and broke into the CBD industry in 2014. The brand operates with a vision to promote healthy minds and bodies through a line of premium cannabinoid wellness products for health-conscious individuals.
NuLeaf Naturals began with standard full-spectrum tinctures or drops. It has since expanded with new products, including CBD soft gel capsules. Its full-spectrum CBD oil products contain no additives for premium quality products.
The brand has over 20,000 high-rated customer reviews, proving that its loyal consumers highly trust NuLeaf Naturals CBD products. The brand makes its independent lab test results available on its website for easy access and quality checking.
The lab results provided on the NuLeaf Naturals website include the cannabinoid and terpene profiles for customers to confirm the products’ high CBD potency and legal THC content. Lab results detail the high concentration of CBD and significant CBC, CBG, CBN, and other cannabinoids to achieve the entourage effect.
A study revealed the antifungal and antimicrobial effects of CBC and CBG(4). Meanwhile, research demonstrated that CBN possesses anticonvulsant and anti-inflammatory properties(5).
The brand also makes the contaminant profiles available so you can easily confirm that NuLeaf Naturals CBD products are free from heavy metals, residual solvents, pesticide residue, and microbial contaminants.
NuLeaf Naturals employs an advanced cultivation program to assure its customers that its products are safe and regulated. The brand has total control of its production process, from farming organic hemp plants grown in Colorado to delivering to store shelves.

A study showed that CBD had numerous potential health benefits that may help with many ailments and medical conditions, including chronic pain, anxiety, sleeping problems, and arthritis(6). However, more longitudinal and comprehensive studies are needed.
Due to FDA regulations, no CBD manufacturer is allowed to make health claims about CBD products.
Thus, NuLeaf Naturals encourages all its customers to research the widely available information online regarding CBD oil and its side effects. Still, it is best to consult with a physician before purchasing any CBD product.
NuLeaf’s vision is to pave the way for a line of cannabinoid wellness products that promote a healthy body and mind(7). Its ultimate goal is to help people and their loved ones live a happier, healthier life.
NuLeaf Naturals strives to deliver only the highest grade products in their pure and simple form. Its CBD oil is all-natural, with no additives or preservatives, and contains all the synergistic cannabinoids, terpenoids, essential oils, and other compounds of the original plant.
Still, the best course of action for individuals contemplating using CBD for the first time or wanting to include CBD in their regimen is to consult with a doctor experienced in cannabis use. Those who are already taking prescription medications should inform their primary care physician before taking any CBD product.
