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.

Green Malay Kratom Explained: The Long-Lasting Green

Green Malay is one of the most enduring kratom strains in the consumer market — known for unusually long duration (often 6+ hours per dose), smooth balanced effects, and a distinctive alkaloid profile compared to other greens. Here is what makes Green Malay different, who tends to prefer it, and how to dose it.

White Vein Kratom Explained: The Morning Energy Vein — White vein kratom is the most stimulating of the three primary vein colors. Harvested from young leaves and dried fast to preserve fresh mitragynine, whites deliver focus, energy, and a clear mood lift — typically with a shorter duration than greens or reds. Here is the biology, the major white strains, dose ranges, and exactly when a white is the right pick versus a green or red.
Green Vein Kratom Explained: The Balanced Middle Ground — Green vein kratom sits between red and white — typically described as a moderate energizer with mild relaxation, smoother and longer-lasting than white vein but more functional than red. The vein color comes from when the leaf is harvested and how it is dried, not from a separate plant. Here is what greens actually deliver, the strains most associated with the green profile, and who tends to find greens the best fit.
