What to expect

Taking kratom capsules

How it feels

Many people describe kratom as a smooth, functional shift in how they feel. How much you take shapes the experience, and everyone responds a little differently, so let your first serving be your guide.

Give it time

Everyone responds differently, so there is no set timeline. With capsules, wait at least an hour before taking more.

How to start

Start with 2 capsules with water and wait at least an hour before taking more. Each capsule is pre-measured, so counting capsules keeps your serving consistent.

What's inside

Honest ingredients

Leaf of Mitragyna speciosa, the kratom tree, taken through a longer drying process, then milled and filled into Yellow Gold capsules. Mitragynine is the most abundant natural alkaloid in the leaf.

How

How Does It Work?

Yellow Gold comes pre-portioned, so two capsules is always the same starting serving. Take them with water and wait at least an hour before deciding on more. Everyone responds differently, and your first serving tells you more than any chart.

When

When Do I Use It?

Questions, answered

Where is Yellow Gold on the kratom strain spectrum?

Our strains run White, Aged, Mixed, Green, Yellow, Orange and Red. No. 491 Yellow Gold is printed as a Yellow Strain on the bag, so it sits between Green and Orange. Many people choose it for the middle of the day.

How many capsules is a first serving?

Two. Take them with water and wait at least an hour before deciding on more. Four capsules is the middle of the range and six is the top, so move up one step at a time. Like caffeine and sugar, kratom may be habit-forming. Use kratom responsibly and only as directed.

Which Yellow Gold bag should I buy?

If you are new to Yellow Gold, the 10 capsule bag gives you five 2-capsule servings to try it. The bigger the bag, the less you pay per capsule, up to the 360. A subscription can deliver it every 7, 14 or 30 days.

Is No. 491 Yellow Gold lab tested?

Yes, as part of our yellow kratom testing. Murray-Brown Laboratories, an independent lab, tested a sample described as Korthals Yellow Kratom for its alkaloid content; the certificate is dated December 2025. Our Test Results page lists that same certificate for several strains, including Yellow Gold, so it is not a test of No. 491 alone. It is also linked on this page.

How should I store Yellow Gold capsules?

In the sealed bag, in a cool, dry place out of direct sunlight. Keep it out of reach of children and pets.

What is kratom?

Kratom comes from the leaves of the Mitragyna speciosa tree, native to Southeast Asia, where it has been part of daily life for centuries. The leaf is dried and milled into powder, then packed into capsules, brewed, or made into extracts. Its natural leaf compounds are called alkaloids, and mitragynine is the most abundant one.

How much kratom should I take?

There is no single answer, because everyone responds differently. Start with the lowest serving on the product page and give it time before deciding on more. Smaller servings are commonly chosen for a lift and larger servings for winding down. A small kitchen scale helps if you are using powder. Like caffeine and sugar, kratom may be habit-forming. Use kratom responsibly and only as directed.

How long should I wait before taking more?

Everyone responds differently, so there is no set timeline. Start with the lowest serving on the product page and give it time before taking more: at least an hour for capsules, and at least 30 minutes for other formats.

Can you ship kratom to my state?

We cannot ship kratom to Tennessee. Kratom is also restricted in a handful of other states and in some counties and cities. Our checkout will flag an address we are not able to ship kratom to, and the current list of restricted areas is in our site footer. If you are in a restricted area, our stores and our non-kratom selection are still open to you.

Can I pick it up in store?

Many kratom items are available for in-store pickup, and shelf selection can differ from what is online. Choose the pickup option on this page or at checkout to see which nearby locations have it in stock.
