Read moreOur Verdict: Yes, with a caveat. NuLeaf Naturals earns a 9.0/10 for product quality and testing transparency. The higher price is justified by consistently accurate lab results, minimal ingredient lists, and a full-spectrum formula that loyal customers swear by. The caveat: if you need flavored options or targeted formulations (sleep, stress, energy), NuLeaf’s stripped-down product line may feel limiting.
NuLeaf Naturals launched in 2014 out of Denver, Colorado — making it one of the oldest CBD companies still operating in the United States. The brand has maintained a deliberately narrow focus since day one: full-spectrum CBD oil made with minimal ingredients and no artificial additives.
While competitors expanded into gummies, topicals, beverages, and pet products, NuLeaf kept its line tight. That discipline has earned the brand a cult following among CBD users who value simplicity and consistency over variety. User review aggregators give NuLeaf a 9.5 out of 10 rating, with repeat customers citing product reliability and customer service as top reasons for loyalty.
The company grows its hemp in Colorado and controls most of its production process in-house, from extraction through bottling. That vertical integration gives NuLeaf more quality control than brands that rely on third-party manufacturers.
NuLeaf’s lineup is intentionally small:
CBD Oil (Full Spectrum): The flagship product. Available in 300mg, 900mg, 1800mg, and 6000mg bottles. The formula contains full-spectrum hemp extract and organic virgin hemp seed oil. Nothing else.
CBD Capsules: The same full-spectrum extract in softgel form. Available in 300mg and 900mg bottles with 15mg per capsule.
CBD Balm: A topical option with full-spectrum extract, beeswax, coconut oil, and essential oils. Available in 300mg and 900mg sizes.
Multicannabinoid Blends: NuLeaf expanded into CBG, CBC, and CBN blends in recent years. These oils combine CBD with specific minor cannabinoids for targeted effects — CBN for sleep, CBG for focus, CBC for mood.
Pet CBD: Full-spectrum pet oil available in sizes calibrated for different animal weights. For a deeper look at pet-specific products, CBDPet.com covers the pet CBD market in detail.
This is where NuLeaf separates itself from most competitors. The brand publishes batch-specific certificates of analysis from independent labs. We reviewed six recent COAs and found CBD content within 3% of label claims across all samples — well above industry average accuracy.
The testing covers potency (cannabinoid profile), pesticides, heavy metals (arsenic, cadmium, lead, mercury), microbial contaminants, and residual solvents. Every COA we checked came back clean across all categories.
NuLeaf uses CO2 extraction, which is considered the cleanest method for preserving the full cannabinoid and terpene profile without introducing chemical solvents. The resulting oil has a natural, earthy hemp flavor — which brings us to the one consistent criticism.
The taste. Because NuLeaf doesn’t add flavoring, sweeteners, or carrier oils beyond hemp seed oil, the product tastes like hemp. If you’ve used flavored CBD oils from other brands, the switch to NuLeaf’s unflavored formula takes adjustment. Long-term users say you get used to it. First-time buyers may find it off-putting.
For context on why third-party testing matters and what to look for in a COA, SafeCBD.com has a detailed guide.
NuLeaf occupies a specific niche: premium, no-frills, full-spectrum CBD. Here’s how it stacks up against comparable brands:
| Feature | NuLeaf Naturals | Charlotte’s Web | Lazarus Naturals |
| Spectrum | Full | Full | Full & Isolate |
| Hemp Source | Colorado | Colorado | Oregon |
| Flavored Options | No | Yes | Yes |
| Price/mg (oil) | $0.09 | $0.10 | $0.03 |
| Product Variety | Limited | Wide | Wide |
| Lab Accuracy | ±3% | ±5% | ±5% |
| Organic Cert | No (organic practices) | Yes | Yes |
NuLeaf’s lab accuracy is its strongest competitive advantage. The tighter margin means you’re more likely to get exactly the dose you expect. For daily users tracking their intake, that consistency matters.
The price gap between NuLeaf and budget brands like Lazarus Naturals is significant — roughly three times the cost per milligram. Whether that premium is worth it depends on how much you value NuLeaf’s specific combination of minimal ingredients, tight lab accuracy, and production control.
NuLeaf’s pricing structure rewards larger purchases:
| Product | Size | Price | Price/mg |
| CBD Oil | 300mg | $38.50 | $0.13 |
| CBD Oil | 900mg | $99.00 | $0.11 |
| CBD Oil | 1800mg | $179.00 | $0.10 |
| CBD Oil | 6000mg | $439.00 | $0.07 |
| Capsules | 900mg | $109.00 | $0.12 |
| Balm | 900mg | $99.00 | $0.11 |
The 6000mg bottle brings the cost down to $0.07 per milligram — competitive with mid-range brands. The smaller bottles carry a steeper premium. If you plan to use NuLeaf long-term, buying the largest size makes economic sense.
NuLeaf offers a subscribe-and-save option with 20% off recurring orders, which drops the 1800mg bottle to $143.20. They also provide a 30-day money-back guarantee on first purchases.
| Pros | Cons |
| Industry-leading lab accuracy (±3%) | No flavored options |
| Minimal ingredient list | Higher price than budget brands |
| In-house production from seed to bottle | Limited product variety |
| 9+ year track record | Earthy taste not for everyone |
| Multicannabinoid blends available | No gummy format |
| Colorado-grown hemp |
NuLeaf Naturals is a brand for people who know what they want. It won’t win over shoppers looking for variety, flavored options, or the lowest price per milligram. But for users who prioritize product consistency, minimal ingredients, and lab-verified potency, NuLeaf delivers at a level few competitors match.
The 9.5/10 user rating isn’t inflated. Customers who stay with NuLeaf tend to stay for years. The brand’s strengths — tight quality control, simple formulations, transparent testing — compound over time. You learn your dose, you know what to expect, and the product delivers the same experience bottle after bottle.
With federal regulations creating uncertainty around CBD product standards, brands with NuLeaf’s level of testing and transparency are better positioned than most to meet whatever compliance requirements emerge.
Rating: 9.0/10

Is NuLeaf Naturals third-party tested? Yes. Every batch is tested by an independent lab for potency, pesticides, heavy metals, microbial contaminants, and residual solvents. COAs are accessible on the product page by batch number.
Does NuLeaf CBD oil contain THC? NuLeaf’s full-spectrum oil contains naturally occurring THC at levels below 0.3% — the federal legal limit. If you need a THC-free option, NuLeaf is not the right fit. Consider broad-spectrum alternatives instead.
How much NuLeaf CBD oil should I take? The company recommends starting with half a dropper (about 30mg for the 1800mg bottle) and adjusting based on your response. Most regular users settle between 25-50mg per serving, taken once or twice daily.
Does NuLeaf offer discounts? The subscribe-and-save program provides 20% off. NuLeaf also offers occasional promotions and a loyalty points program. They do not currently offer a veterans or disability assistance program like some competitors.
Where is NuLeaf hemp grown? All hemp is grown on licensed farms in Colorado using organic farming practices, though the company does not hold USDA Organic certification at this time.
