Is 4 Leaf Co the same company as 4 Leaf Herbals?

Yes. '4 Leaf Co' is a common shorthand for 4 Leaf Herbals — the official company name. Both refer to the same Florida-based botanical wellness brand established in 2014 that produces premium lab-tested kratom extracts, gummies, and MitraNade beverages. You may also see the brand referenced as 4Leaf Herbals, 4Leaf Co, Four Leaf Herbals, or Four Leaf Co — all are the same company. The official domain is 4leafherbals.com.

Is 4 Leaf Herbals an AKA GMP Qualified Vendor?

Yes. 4 Leaf Herbals is an American Kratom Association GMP Qualified Vendor, meaning we pass an annual third-party audit of our manufacturing, sourcing, testing, and labeling practices. AKA GMP qualification is the strongest single trust signal in the kratom industry.

Are 4 Leaf Herbals products lab-tested?

Yes. Every batch of every 4 Leaf Herbals product — extracts, gummies, MitraNade beverages — is third-party tested at an ISO 17025-accredited laboratory. Certificates of Analysis show alkaloid content (mitragynine and 7-hydroxymitragynine), heavy metals (lead, arsenic, cadmium, mercury), and microbial contamination panels. All COAs are published openly on our Lab Results page.

Where can I buy 4 Leaf Herbals products?

4 Leaf Herbals products are available through our online store with shipping to most US states (excluding Alabama, Arkansas, Indiana, Rhode Island, Vermont, Wisconsin, and Washington DC where kratom is prohibited). We also have retail stockists across Florida and other states — see our store locator.

How do I know what dose of kratom to take?

Start low: most adults can begin with 2–3 grams of leaf powder for general use, less for extracts based on the mitragynine percentage on the Certificate of Analysis. Effects vary by individual — start at the low end and adjust upward over multiple sessions to learn your personal response. Avoid daily use to prevent tolerance and dependence. See our Kratom Dosage Guide for comprehensive dose-by-experience-level guidance.

Is kratom legal in my state?

Kratom is legal at the federal level in the United States and is legal in most US states. As of 2026, kratom is illegal at the state level in Alabama, Arkansas, Indiana, Rhode Island, Vermont, and Wisconsin, and restricted in Washington DC. Several other states have local restrictions (e.g., Sarasota County FL, City of San Diego CA). See our state-by-state kratom legality guide.

What's the difference between natural-leaf kratom and synthetic 7-OH products?

Natural-leaf kratom contains the full alkaloid spectrum of dried Mitragyna speciosa leaves, with mitragynine as the dominant alkaloid (60–70% of total alkaloids) and 7-hydroxymitragynine present in small amounts (under 2% of total alkaloids). Synthetic 7-OH products concentrate isolated 7-hydroxymitragynine to many times its natural-leaf level, producing a chemically and pharmacologically distinct product that is banned under most KCPA-style state laws and the focus of a 2025 FDA consumer alert. 4 Leaf Herbals does not sell synthetic 7-OH products.

What's a Certificate of Analysis (COA) and why does it matter?

A Certificate of Analysis is a third-party laboratory report documenting the test results for a specific batch of a kratom product — alkaloid content (mitragynine and 7-OH percentages), heavy metals, microbial contamination, and other safety panels. Per-batch COAs from accredited labs are the only objective verification that a kratom product is safe and accurately labeled. We publish COAs for every batch openly on our Lab Results page.

Can I take kratom during pregnancy or breastfeeding?

No. Kratom should not be used during pregnancy or while breastfeeding. Documented cases of neonatal abstinence syndrome from in-utero kratom exposure exist in clinical literature. The American Kratom Association, OB-GYN consensus, and FDA all align on this contraindication. If you're pregnant or planning to be, discuss with your OB-GYN before any kratom use.

Our Quality Testing Process: From Raw Leaf to Sealed Product

Quality control in kratom is not one test — it is a sequence of independent checkpoints from the moment leaf material arrives to the moment a sealed product ships. Here is the step-by-step quality-control workflow every 4 Leaf Herbals product goes through, who is accountable at each step, and how the chain of evidence makes its way onto your COA.

How 4 Leaf Herbals Sources Its Kratom: The Full Supply Chain, Top to Bottom — Most kratom on the US market changes hands through anonymous brokers between Indonesian growers and US retailers — which is why so many products test poorly, drift in alkaloid content, or carry inconsistent contamination profiles. We do things differently. Here is the full supply chain behind every product we ship: grower relationships, sourcing protocols, transport, lab testing, and packaging.
Why We Third-Party Test Every Single Batch (And What That Actually Means) — Per-batch third-party testing is the single most important quality signal in kratom — and the single easiest thing for vendors to fake or skip. Here is what real per-batch testing looks like, what we test for, why we publish every COA openly, and how to spot the vendors who say they test but actually do not.
