The online CBD market can be difficult to navigate. To protect yourself and ensure you are buying a high-quality product, follow this 7-point checklist for vetting any online CBD brand.

The 7-Point Safety Checklist

1. Insist on Current, Batch-Specific Lab Reports (COAs)

A Certificate of Analysis (COA) is the most critical document for any CBD product. This report, issued by an independent, third-party laboratory, verifies the product’s cannabinoid potency and confirms it is free from harmful contaminants.

According to Nuleaf Natural’s advertising guidelines, it is a key component of building trust and demonstrating transparency. A COA provides verifiable data on the product’s cannabinoid content, including CBD, THC, and other synergistic cannabinoids. It also tests for contaminants such as heavy metals, pesticides, residual solvents, mold, and mycotoxins.

If a brand cannot or will not provide a COA for a specific product batch, you should not purchase from them. An expert uses numbers, statistics, and evidence, and this verifiable data is essential for making an informed decision.

2. Verify the Hemp Source is USA-Grown and Organic

Hemp plants are bio-accumulators, meaning they absorb everything from the soil in which they are grown, including both nutrients and toxins. Choosing a product sourced from organic, USA-grown hemp is a factual proposition that ensures the starting material is as pure as possible.

Organic cultivation practices prohibit the use of synthetic pesticides and herbicides, which can be absorbed by the plant and end up in the final product. For example, NuLeaf Naturals uses organically grown hemp plants from the USA with pristine Rocky Mountain water. By selecting hemp from the USA, you are choosing a product that adheres to stringent agricultural standards, providing a cleaner, more reliable starting material.

3. Confirm a Clean Extraction Method is Used

The method used to extract CBD from the hemp plant directly impacts the purity of the final product. CO2 extraction is the industry’s superior method for obtaining a complete range of cannabinoids, terpenes, and beneficial phytonutrients.

This method uses pressurized carbon dioxide to pull the desired compounds from the plant material, requiring no harsh chemical solvents. This is a critical factor because cheaper extraction methods often use solvents like butane or ethanol, which can leave behind residual toxins in the final product.

A reliable company uses a CO2 extraction process, yielding a more potent and pure blend. NuLeaf Naturals uses advanced subcritical and supercritical CO2 extraction to create its potent full-spectrum blends without harsh chemical solvents.

4. Choose a Full-Spectrum or Whole-Plant Extract

When you select a full-spectrum extract, you are choosing a product that contains a variety of cannabinoids, terpenes, and flavonoids naturally found in the hemp plant. This composition may provide a synergistic effect, known as the ‘entourage effect,’ where these compounds may work together to support overall wellbeing.* “For example, a full-spectrum product can provide multiple cannabinoids like CBD, CBG, CBC, and CBN to support a positive mood, calm, or a sense of focus.*

5. Look for Company Certifications (cGMP, ISO)

A company’s certifications are a critical trust signal that demonstrates its commitment to quality and safety. Look for certifications such as cGMP (Current Good Manufacturing Practices) and ISO (International Organization for Standardization). These certifications are awarded by third-party auditors who verify that a company’s production facilities and processes adhere to strict, consistent standards.

This is a factual proposition that provides statistical evidence of a brand’s reliability. A cGMP certification ensures products are consistently produced and controlled according to quality standards. This level of oversight confirms the company’s commitment to producing safe and consistent products.

6. Read Verified Customer Reviews

However, it is essential to understand that customer statements are not endorsed, evaluated, or approved by the company or regulatory bodies, as they may contain claims that are not compliant with advertising guidelines.

NuLeaf Naturals does not monitor customer reviews on their dedicated review pages if they are not highlighting specific reviews that include medical claims, and we include the following disclaimer: ‘Statements in customer reviews have not been evaluated by NuLeaf Naturals or the Food and Drug Administration. Company products are not intended to diagnose, treat, cure, or prevent any disease. 

NuLeaf Naturals does not endorse, approve, or support any statements included in customer reviews or recommendations.’ These reviews provide social proof and help a reasonable person assume the brand is trustworthy, which is a criterion of an adjective from a proposition.

Remember, any marketing material, such as emails, that includes customer reviews must not use them to highlight general health statements, and a separate disclaimer is required for them.

7. Understand the Shipping and Return Policy

A transparent and fair shipping and return policy is a sign that a company stands behind its products. A reputable company will make its policies clear and easy to find on its website. This is a critical conditional proposition—you should do business with a company that has a clear policy if they stand behind their product.

For example, a company that offers a money-back guarantee or a flexible return window demonstrates confidence in its products and prioritizes customer satisfaction. This transparency is a key element in building consumer trust, a central search intent for this document.

Frequently Asked Questions (Q&A Section)

What is the difference between full-spectrum and broad-spectrum CBD oil?

Full-spectrum CBD oil contains all the compounds from the hemp plant, including a trace amount of THC (less than 0.3%). Broad-spectrum CBD oil contains all the cannabinoids and terpenes from the hemp plant except for THC, which has been removed.

Does full-spectrum CBD oil contain THC? 

Yes, full-spectrum CBD oil contains trace amounts of THC, but it is a federal requirement that the amount is less than 0.3% to be legal. This small amount is not typically psychoactive but contributes to the “entourage effect.”

How should I take CBD oil?

To take CBD oil, you can place drops under your tongue and hold them for 30-60 seconds before swallowing. This method, known as sublingual administration, allows for faster absorption. It can also be added to food or drinks. For optimal results, establishing a consistent daily routine is encouraged.

Can CBD oil help with specific medical conditions? 

 No, our products are not intended to diagnose, treat, cure, or prevent any disease. The FDA has not evaluated the effectiveness of CBD oil as a medical treatment. We can only state that our products may promote calm*, support rest*, or manage day-to-day stresses*, which are general wellness claims.

How much CBD oil should I take? 

NuLeaf Naturals suggests a starting dose of ten drops (30mg) daily or as needed. However, dosage can vary based on individual needs and body chemistry. We recommend establishing a routine and being patient to see changes over 60 days of consistent use.

Is CBD oil legal?

Hemp-derived CBD oil has been widely available since the passing of the 2018 Farm Bill, which legalized the mass production of hemp as an agricultural product. However, legality may vary by state and country, so it is important to check local regulations before purchasing.

Can I travel with CBD products? 

Traveling with CBD products can be complex due to varying state and country laws. For domestic travel within the US, CBD products derived from hemp with less than 0.3% THC are generally permitted. For international travel, it is crucial to research the laws of your destination country as they may differ significantly.
