Two Products — Which Is Right for You?
Medterra offers two meaningfully different CBD oil formulas. Understanding the distinction is important before purchasing — they are not interchangeable options.
Medterra is one of the most established names in the CBD category and one of only a handful of brands to hold US Hemp Authority certification — an audited standard that goes beyond basic third-party lab testing. Their product lineup is broader than most brands on this list, but the two CBD oil tinctures reviewed here serve meaningfully different purposes.
Daily Relief CBD Isolate Oil. The isolate formula uses 99%+ pure CBD combined with organic MCT oil — no other cannabinoids, no THC. This is the most straightforward CBD oil Medterra offers. With 3,368 verified reviews and a 4.5-star average, it's also their most-reviewed product in this category. The Healthline Editor's Pick recognition for 2025 is a notable third-party validation. At $39.99 for 500mg ($29.99 on subscription), it's competitively priced, and the 2-pack and 3-pack bundle options improve value further.
Max Relief + Relax Full Spectrum Oil. The full spectrum formula goes significantly further than a standard CBD oil — combining CBD, CBG (cannabigerol), THC, and additional minor cannabinoids in organic MCT oil. CBG is a minor cannabinoid that is attracting growing interest for its potential synergistic effects alongside CBD. At 16mg CBD + 16mg CBG + 2mg THC per serving, this is a more complex formula with a broader cannabinoid profile. It carries a 21+ age restriction and drug test warnings consistent with its THC content.
Lab testing & transparency. Medterra publishes Certificates of Analysis for all products. Their US Hemp Authority certification requires compliance with audited quality standards covering sourcing, processing, and testing — a meaningful differentiator from brands that rely solely on self-reported lab testing.
The Max Relief + Relax formula contains 2mg THC per serving by design. This carries usage considerations that do not apply to the THC-free Daily Relief formula.
⚠ Max Relief + Relax — Adult Use Only (21+)
Adult use only — 21+ age restriction applies to this product.
Contains THC derived from hemp — use may result in a positive drug screen.
Consult a healthcare professional before use, especially if taking medications or if you have a medical condition.
Not recommended during pregnancy or nursing.
Farm Bill compliant — total delta-9 THC does not exceed 0.3% on a dry weight basis.
How to Use
1
Daily Relief (Isolate): Take 1 full dropper once or more times per day. Can be taken sublingually or mixed into a drink.
2
Max Relief + Relax (Full Spectrum): Start with 1 full dropper once per day. Assess how you feel and adjust your dosage accordingly.
3
Sublingual delivery: For both formulas, placing under the tongue and holding for 60 seconds before swallowing supports more efficient absorption than swallowing directly.
4
Consistency matters: Daily use over time is generally recommended for evaluating how CBD works for your individual needs.
General usage guidance only. Do not use Max Relief + Relax if you are subject to drug testing. Consult a healthcare professional before starting any new supplement.

Frequently Asked Questions
The Daily Relief is a CBD isolate — it contains 99%+ pure CBD and organic MCT oil with zero THC. The Max Relief + Relax is a full spectrum blend that includes CBD, CBG, THC, and additional minor cannabinoids in organic MCT oil. The isolate is best for those who want a predictable, THC-free experience. The full spectrum formula is designed for those seeking a broader cannabinoid profile and is subject to a 21+ age restriction.
The Daily Relief CBD Isolate Oil is THC-free (0% THC) and is generally considered a safer option for users subject to drug testing. However, we recommend consulting with your employer or testing provider before use, as testing protocols and sensitivities vary.
CBG (cannabigerol) is a minor cannabinoid found in the hemp plant that is attracting growing research interest. Medterra includes 16mg CBG per serving in the Max Relief + Relax formula alongside 16mg CBD and 2mg THC, with the intent of providing a broader cannabinoid profile than CBD alone. Research into CBG is still in early stages.
The US Hemp Authority certification is an industry self-regulatory program that requires brands to meet audited quality standards covering hemp sourcing, processing, and third-party lab testing. Unlike simply publishing lab results, US Hemp Authority certification involves independent third-party audits — a higher bar than most brands in the CBD category meet.
Medterra offers a 30-day money back guarantee. If you are unsatisfied, you have 30 days from the time you receive your products to return them and request a refund.
