What do the words on a Smart Addicts pack mean?

Every pack states the amount in one piece and the amount in the whole pack, both in milligrams, so two products can be compared without arithmetic.

Mitragynine is the alkaloid measured in kratom leaf, and the figure printed is a measured amount of material, not an instruction. Proprietary blend on a mushroom tablet means the total weight of the blend is given while the split between species is not. Lot number is the code that identifies one production run, printed on the back beside the best before date. Serving size is how many pieces the label counts as one serving, which is not always one piece.

The words below are defined the way they are used on our own labels. Nowhere on a pack does a number describe an effect.

Ingredients and terms

What the words on our packs actually mean.

Definitions only. Nothing here says what a product does.

Kratom Also called Mitragyna speciosa
A tree in the coffee family that grows across Southeast Asia. Its leaf is dried and ground, and that powder, or an extract of it, is what goes into a kratom product. On our labels: Kratom Addicts
Leaf powder
Dried kratom leaf, milled. Whole leaf rather than a concentrate, so it carries whatever alkaloid content the leaf itself had.
Extract
Material concentrated from the leaf, so the same weight carries more alkaloids than plain leaf powder. Weight for weight the two are not interchangeable.
Alkaloid
A naturally occurring nitrogen compound found in many plants. Caffeine is one. In kratom, the alkaloids are what a laboratory measures.
Mitragynine Also called MIT
The alkaloid present in the largest amount in kratom leaf. A lab report gives the measured amount, as a percentage of the material or in milligrams per piece. On our labels: MIT in a product name
Amount per piece
How much of the named ingredient sits in one tablet, gummy or capsule. This is the figure to compare across products, since pack sizes differ.
Serving size
How many pieces the label counts as one serving. A serving is not always one piece, so check before you compare two products.
Functional mushroom
A culinary or supplement mushroom such as lion’s mane, reishi or cordyceps, used here as a food ingredient. On our labels: Shruums Addicts
Fruiting body
The part of a mushroom you would recognize as a mushroom, above ground. A label that names it is telling you which part went in.
Mycelium
The root-like network a mushroom grows from, often cultivated on grain. It is different material from a fruiting body.
Mushroom blend
More than one mushroom in one product. The label lists which ones and how much of each. On our labels: Mushroom Blend
Chewable tablet
A pressed tablet meant to be chewed rather than swallowed whole. It carries binders and a sweetener alongside the active ingredient. On our labels: Chewable Tablets
Gummy
A soft chew set with either pectin or gelatin. Pectin suits vegans, gelatin does not. On our labels: Gummies
Pectin
A setting agent made from fruit, used in place of gelatin, which comes from animals.
Vegan
Made without animal-derived ingredients. On a gummy that means pectin in place of gelatin. On our labels: Vegan
Non-GMO
Made without ingredients from genetically modified organisms. A claim about how the ingredients were grown, and nothing about strength. On our labels: Non GMO
Lot number Also called Batch number
The code printed on the pack that identifies its production run. Use it to find the lab report for what you actually bought.
Certificate of analysis Also called COA
The lab document for a lot. It lists what was tested, the method used and the result for each item.
Heavy metals
Lead, arsenic, cadmium and mercury. Plants take them up from soil, so a laboratory measures them against a limit.
Microbial testing
Bacteria, yeast and mold counts, plus named organisms such as salmonella and E. coli.
Best before
The date up to which the maker expects the product to hold its stated quality. It speaks to quality rather than safety.
Subscription
Buying on a repeating schedule instead of once. You set the delivery frequency when you order and can change it later.
