Last revised 18 September 2026. Originally published 10 January 2021. We revise this guide whenever new lab results, product changes or state law changes come in, so the date above tells you how current it is. See How we revise this guide.
What this page is and is not
Kratom is not a weight-loss product. We make no claim that kratom, or any product named on this page, diagnoses, treats, cures, prevents or alleviates any disease, medical condition or withdrawal condition. We make no claim that it causes or aids weight loss. The FDA has not approved kratom for any use and considers kratom-containing dietary supplements adulterated (FDA and Kratom).
This page also gives no serving or dosing guidance. Read the product label, and talk to a medical professional before adding any botanical to your routine. For adults 21 and over only. Kratom is illegal in some states and cities, so check your local law before you order.
The honest answer
People search for kratom and weight loss every day, so here is the plain version. There is no established weight-loss benefit, there is no approval for that use, and nothing in our catalog is sold for it. We are not going to write around that to keep you on the page.
What we can tell you is what is actually in the bag. Kratom is the dried, milled leaf of Mitragyna speciosa, a tree in the coffee family that grows in Southeast Asia. Mitragynine is the alkaloid that labs measure most often, and the percentage printed on a certificate of analysis is a real number you can check. That is the difference between a product that is explained and a product that is only marketed.
So that is what this guide does. It lays out what GRH actually stocks by vein color, growing region, format, testing and price, and it explains the strain names you will run into elsewhere. No effects, no promises, no serving advice.

The short version
- Kratom is not a weight-loss product and this page makes no health, disease or efficacy claim of any kind.
- The FDA has not approved kratom for any use.
- Vein color is a harvest sorting label tied to leaf maturity. It is not a promise about anything.
- GRH stocks four single strains and five blends. Most of the strain names you see in roundups elsewhere, we do not carry.
- Every GRH batch is third-party tested for alkaloid content and contaminants, and we publish a COA per batch.
- Powder runs 15 to 100 dollars depending on size. Capsules run 10 to 120 dollars.
- We give no serving guidance. Read the label and talk to a medical professional.
- Kratom is banned in several states and in some cities. We run restricted-state shipping verification, but checking your own law is on you.
- Every product link on this page points to a GRH page. We do not send you to sellers whose testing we cannot see.
What vein color actually means
Green, white and red refer to the color of the stem and the veins running through the leaf when it is picked. That color tracks leaf maturity on the tree and, in some cases, how the leaf was dried afterward. Farmers and processors have sorted leaf this way for a long time because it is a visible, practical way to keep batches separate.
That is the whole of it. Vein color is a sorting label, not a specification. Two green vein batches from different farms can test differently, which is exactly why we publish alkaloid content per batch instead of asking you to trust a color.
Region names work the same way. Maeng Da, Borneo, Malay, Sumatra, Thai and Indo point at growing regions and processing traditions. They tell you where leaf came from. They do not tell you what is in it. The COA does.
What a COA actually tells you
A certificate of analysis is a third-party lab report tied to a specific batch. On a GRH COA you get the batch or lot number, the date, the lab, the measured alkaloid content, and screening for heavy metals, microbials and adulterants.
Three things to check on any vendor COA, ours included. First, the date, because a lab report from two years ago says nothing about the bag in your hand. Second, the lot number, because it has to match the bag. Third, whether the vendor publishes results for every batch or only for one showcase batch.
Most kratom is marketed, not explained. Asking for a current, batch-matched COA is the fastest way to tell the difference, and it works on us too.
How we compared what we stock
None of these measure weight loss, metabolism or any physical effect, because that is not what we are able to measure or claim. They measure the things a buyer can actually verify.
- Batch consistency. Does the alkaloid content stay in a tight range from lot to lot?
- Lab testing and COA access. Is there a current, batch-matched third-party report you can read before you buy?
- Sourcing clarity. Can we name the region and the processing path, or are we repeating a marketing name?
- Format availability. Powder, capsules, or both, and in what sizes.
- Value. Price per gram across the size range.
Ratings run out of 5 and reflect our own stocking and testing record. They are not a measure of efficacy for anything.
GRH single strains
These four are the single-origin leaf products we actually carry. Everything else in our lineup is a blend or an extract.
Green Maeng Da
Green vein leaf, Maeng Da processing. This is our best-selling single strain. It is finely milled, it comes in both formats, and we publish a third-party batch report for every lot.
- Formats: powder and capsules
- Price: powder 15 to 100 dollars by size, capsules 10 to 120 dollars
- Batch consistency 5/5, lab testing 5/5, sourcing clarity 5/5, format availability 5/5, value 5/5
- Worth knowing: the powder tastes earthy, which is why a lot of people move to capsules
White Maeng Da
White vein leaf, same Maeng Da processing, picked at a different point in leaf maturity. Same milling and same per-batch testing as the green.
- Formats: powder and capsules
- Price: powder 15 to 100 dollars by size, capsules 10 to 120 dollars
- Batch consistency 4.5/5, lab testing 5/5, sourcing clarity 5/5, format availability 5/5, value 5/5
- Worth knowing: vein labels are applied inconsistently from vendor to vendor across this category, so the batch report is what tells you what you actually have
Red Maeng Da
Red vein leaf, Maeng Da processing. Rounds out the vein set from a single processing path, which makes it the easiest like-for-like comparison in the catalog.
- Formats: powder and capsules
- Price: powder 15 to 100 dollars by size, capsules 10 to 120 dollars
- Batch consistency 4.5/5, lab testing 5/5, sourcing clarity 5/5, format availability 5/5, value 5/5
Super Green
Green vein leaf selected for larger, later-picked leaves. Super is a grading term for leaf size and selection. It is not a strength rating and we do not use it as one.
- Formats: powder and capsules
- Price: powder 15 to 100 dollars by size, capsules 10 to 120 dollars
- Batch consistency 4.5/5, lab testing 5/5, sourcing clarity 4.5/5, format availability 5/5, value 4.5/5
GRH blends
A blend lets us hold a target alkaloid profile steady across lots by combining leaf from more than one source. The names below are product names. They are not descriptions of what the products do, and we are not going to pretend otherwise.
- Joy Blend. Green and white leaf. Our top-selling product overall, though Boost sits within a few percent of it, so treat that ranking as current rather than permanent. Also in capsules.
- Boost Blend. Also in capsules.
- Focus Blend. Also in capsules.
- Relax Blend. Also in capsules.
- Blend Sample Pack, 9 dollars. A low-cost way to try our blends before committing to a full bag.
Other strain names you will see
Search for kratom strains and you will hit roundups listing a dozen names. Most of those pages are selling you something they do not stock. Here is what those names actually mean, and we will say plainly that we do not carry them.
- White Borneo, Green Borneo. Leaf from the island of Borneo. Not currently stocked by GRH.
- Green Malay. Also written Green Malaysian. Leaf from Malaysia. Not currently stocked. We do have a write-up comparing it with Green Maeng Da: Green Maeng Da vs Green Malaysian.
- White Thai, Green Thai. Leaf associated with Thai growing regions. Not currently stocked.
- White Sumatra, Green Sumatra. Leaf from Sumatra. Not currently stocked.
- Green Indo. A broad Indonesian designation. Not currently stocked.
- White Elephant. Named for unusually large leaves. Not currently stocked.
If a name matters to you, ask us and we will tell you honestly whether we can source it and whether we can test it. If we cannot test it, we will not sell it.

Powder, capsules and extracts
Powder
Loose milled leaf. The lowest cost per gram and the easiest format to measure precisely. The taste is earthy and that is the main complaint we hear. Browse GRH kratom powder.
Capsules
The same milled leaf in a capsule shell. You pay a premium per gram for not tasting it and for a pre-filled shell. Browse GRH kratom capsules.
Extracts
Concentrated preparations, a different category from leaf powder and priced accordingly. Concentration also means state rules can treat extracts differently from plain leaf, so check your law specifically before ordering one. Browse GRH kratom extracts.
By vein
If you would rather shop by vein color: Green Vein, White Vein, Red Vein. Or see everything at Buy Kratom.
Legal status and shipping
Kratom is not legal everywhere in the United States, and the map changes. Several states ban it outright, some cities and counties ban it locally, and a number of states regulate concentrated products differently from plain leaf. Some states have moved in both directions in the same year.
We run restricted-state shipping verification, so an order to a jurisdiction we cannot ship to will not go through. That is a backstop, not a substitute for checking your own state and city rules before you order. We deliberately do not publish a state-by-state count here, because the aggregator pages that do are frequently out of date and contradict each other. Check your state legislature or attorney general directly.
Frequently asked questions
Does kratom cause weight loss?
No. We make no claim that kratom causes, aids or is effective for weight loss. Kratom is not a weight-loss product, there is no established weight-loss benefit, and the FDA has not approved kratom for any use. If you are looking for help with weight, that is a conversation for a doctor or a registered dietitian, not a botanical retailer.
Is kratom FDA approved?
No. The FDA has not approved kratom for any use and considers kratom-containing dietary supplements adulterated. You can read the agency position on the FDA and Kratom page.
What is the difference between green, white and red vein?
The color describes the stem and leaf veins at harvest, which tracks leaf maturity and, in some cases, drying method. It is how leaf gets sorted into batches. It is not a specification, and it is not a promise. Check the COA for the batch you are actually buying.
What does Maeng Da mean?
It is a grading and processing name, not a place and not a strength rating. Different vendors apply it differently, which is one more reason to read a batch report instead of a label adjective.
How much should I take?
We do not give serving or dosing guidance, and you should be cautious about any retailer who does. Read the product label and talk to a medical professional.
What are the known risks?
The FDA has warned about potential risks associated with kratom, and kratom is not regulated as a dietary supplement. Nothing on this page is risk-free and none of it is medical advice. Read the clinical overview at NCBI StatPearls: Kratom and speak with a healthcare professional before use.
How do I know a kratom product is tested properly?
Ask for a certificate of analysis for the specific lot you are buying, then check the date, the lot number and whether the lab is independent. A vendor that publishes one COA for one batch and leaves it up for two years is telling you something. The American Kratom Association also runs a vendor standards program you can read about at americankratom.org.
Do you ship to my state?
Our checkout runs restricted-state verification and will block an order we cannot legally ship. Check your own state and city rules first, since local ordinances can be stricter than state law.
Who can buy from GRH?
Adults 21 and over only.
How we revise this guide
This page is not finished and it is not meant to be. We revise it as new information arrives: new lab results, catalog changes, price changes, and changes in state or federal rules. Each revision is dated at the top so you can see how current what you are reading is.
That is deliberate. In this category a lot of content gets published once and left to rot, and a three-year-old page about an unregulated botanical in a moving legal environment is worse than no page. If you find something here that is out of date or wrong, tell us and we will correct it and date the correction.
Revision history. Published 10 January 2021. Revised 18 September 2026: removed all health, effect and serving-related language, rebuilt the product section around the current GRH catalog, added the COA and legal sections, and refreshed image alt text.
Final thoughts
- Kratom is not a weight-loss product and this page makes no health or efficacy claim.
- Vein color and region names are sorting labels. The batch report is the specification.
- We stock four single strains and five blends, and we say so plainly rather than listing a dozen we do not carry.
- Ask for a current, lot-matched COA from any vendor, us included.
- Check your state and local law before ordering. 21 and over only.
If you want to start somewhere, the blend sample pack at 9 dollars is the least expensive way to compare our blends, and Green Maeng Da powder is our best-selling single strain. Either way, read the batch report first, and if anything on this page is unclear, ask our team and we will give you a straight answer.
