Confused about legal CBD dosage on gummies, oils, or drinks? You’re not alone. Shoppers often ask, “How many milligrams of CBD are legally allowed per serving?” The short answer: U.S. federal law doesn’t cap CBD milligrams; it focuses on THC content and labeling. Below, you’ll learn what “legal CBD dosage” means, how to check compliant mg levels, and how state product strength laws and dosage limits may affect what you buy.

Legal CBD Dosage in the U.S.: The Short Version

  • No federal law sets a per-serving CBD milligram cap for over‑the‑counter products.
  • Federal law defines hemp as cannabis with ≤0.3% delta‑9 THC (by dry weight). THC, not CBD, is the primary legal limiter.
  • States add rules (testing, labels, age limits), and some set per‑serving or per‑package THC caps for hemp edibles.
  • Typical market servings range from 5–50 mg CBD, but legality depends on THC and state rules, not the CBD dose itself.
Important: The FDA has not approved CBD as a dietary supplement and restricts certain claims and uses in interstate commerce. Always check current federal and state guidance before manufacturing or selling.

What “Legal CBD Dosage” Really Covers

When people say “legal CBD dosage,” they’re usually asking how much CBD a product can contain without breaking the law. In most U.S. jurisdictions, the law regulates:

  • THC thresholds (e.g., ≤0.3% delta‑9 THC by dry weight)
  • Testing and Certificates of Analysis (COAs)
  • Packaging, serving definitions, and label claims
  • Where and how products can be sold

Some states add dosage limits for THC per serving and per package for hemp edibles. CBD milligrams are rarely capped directly, but your product must still meet all compliance rules, including THC limits and truthful labeling.

How to Check If a CBD Product Is Legally Compliant

Step‑by‑step to verify compliant mg levels

  1. Find the COA (lab report): Scan the QR code on the label or visit the brand’s site. Confirm it matches your product’s batch/lot number.
  2. Check cannabinoids: Verify CBD mg per serving and total CBD. Confirm delta‑9 THC is within limits (federal ≤0.3% by dry weight; your state may also cap THC mg per serving/package).
  3. Match label to lab: Labeled CBD per serving should be within normal variance of the COA (commonly ±10%). Outliers are a red flag.
  4. Read your state’s rules: Look for definitions of “serving,” allowed formats (edibles, beverages, tinctures), age restrictions, and ingredient rules.
  5. Review claims: Avoid disease-treatment claims on labels or websites. Such claims can make an otherwise compliant product “misbranded.”
  6. Keep records: Save COAs, purchase receipts, and lot numbers. This helps if a retailer or regulator requests proof.
“Compliant mg levels” means your CBD and THC values, per serving and per package, align with current federal and state rules, and your labels truthfully reflect the tested content.

Examples You’ll See in the Market

  • Gummies: 10–25 mg CBD per piece is common. Legality hinges on THC thresholds and state labeling/testing rules.
  • Tinctures: 600–1500 mg CBD per bottle (e.g., 30 mL) is typical. Compliance depends on THC, accurate labeling, and COA availability.
  • Beverages: 10–25 mg CBD per can or bottle. Some states set rules specific to drinks (serving size, warnings, or where they can be sold).
  • Topicals: Often 250–1000 mg CBD per container. Usually fewer THC concerns, but testing and label rules still apply.

Where State Rules Can Change the Picture

States adopt different product strength laws for hemp products. Common patterns include:

  • Per‑serving or per‑package THC caps for hemp edibles (e.g., some states limit hemp‑derived THC to single‑digit mg per serving).
  • Age-gating, retail license requirements, and warning statements.
  • Prohibitions or special rules for inhalable hemp or beverages.

One clear example: Minnesota limits hemp‑derived THC in edibles to 5 mg per serving and 50 mg per package. There is no direct CBD mg cap, but THC caps still control how products are formulated and labeled.

Because these rules evolve, always verify current statutes or agency guidance before buying, launching, or shipping products across state lines.

Experience: A Real‑Life Compliance Check

Emma, a distance runner, bought a 25 mg CBD gummy from a new brand. The label promised a QR‑linked COA, so she scanned it in the store.

  • The COA confirmed 24.2 mg CBD per gummy (within normal variance).
  • Delta‑9 THC was “ND” (non‑detectable), well within legal limits.
  • The label had a batch number matching the COA and a standard allergen/warning panel.

Emma felt confident the product hit legal and quality marks. That quick check took two minutes and saved her from guessing about legality.

Legal CBD Dosage vs. Personal Dosing

Legal compliance and personal dosing are different. For personal use, many beginners start with 10–20 mg CBD per day and adjust slowly. Some find benefit at lower doses; others need more.

Safety notes:

  • CBD can interact with medications. Consult a healthcare professional if you take prescriptions (especially those with a grapefruit warning).
  • Do not use CBD to replace prescribed treatments without medical advice.
  • Avoid products making disease-treatment claims without FDA approval.

Label and COA Checklist

  • Brand, product name, net contents, and serving size
  • CBD per serving and per container
  • Delta‑9 THC results and method (e.g., mg/serving, % by weight)
  • Batch/lot number matching the COA, QR code or URL to the COA
  • Ingredient list, allergens, and required warnings
  • Manufacturing/expiration dates and storage instructions

FAQ

Is there a federal legal CBD dosage limit per serving?

No. Federal law does not set a per‑serving CBD cap. It defines hemp by THC content (≤0.3% delta‑9 THC by dry weight). The FDA also restricts certain uses and claims for CBD products. States may add rules, especially for THC in hemp edibles.

How many mg of CBD per gummy is “compliant”?

Compliance isn’t about a single CBD mg number. Most gummies contain 10–25 mg CBD, but legality depends on accurate labeling, COA verification, and meeting THC thresholds and any state serving/package rules. Check your state’s guidance.

Do states set dosage limits for CBD beverages?

Some states regulate beverages differently (serving size, warnings, or retail channel rules). While CBD mg is rarely capped directly, THC and labeling are regulated. Confirm your state’s beverage rules before launching or buying.

How do I calculate compliant mg levels from a COA?
  1. Find CBD mg per unit (e.g., per gummy or per mL) on the COA.
  2. Confirm delta‑9 THC complies (state limits and/or ≤0.3% by dry weight).
  3. Match COA numbers to the label’s serving and total container claims.
  4. Ensure batch/lot numbers align and the test is recent.
Do full‑spectrum products risk failing compliance?

They can if THC drifts above allowed thresholds. Many states also impose per‑serving or per‑package THC caps for hemp edibles. Always verify THC values on the COA and confirm they meet your state’s rules.

Conclusion

There’s no federal milligram cap on CBD per serving. “Legal CBD dosage” comes down to verified testing, truthful labels, and meeting THC thresholds (plus any state‑level dosage limits for hemp edibles). Before you buy or sell, check the COA and your state’s current rules to ensure compliant mg levels.
