How to Read a Nootropic Label: Extract Ratios, Standardization and "Equivalent To"

Last updated: October 2026 · By Tyler, cofounder of Avantera Health · Medically reviewed by Jill Ingenito, DO, FACOG

The short answer: For each herb or mushroom on a nootropic label, look for three numbers. The milligram amount is the weight of the extract in one serving, because that's what labeling rules require. The extract ratio, such as 10:1, tells you how much raw plant went into that extract. The standardization, such as "50% bacosides", tells you how much of a marker compound the extract carries. An "equivalent to" figure is the raw plant amount, not the weight of what's in the serving. To compare two products, or a product and a study, match the form, the ratio and the standardization before you compare milligrams. A 10:1 extract listed at 50 mg was made from 500 mg of raw material.

Where this guide comes from

We're Avantera Health, and we make Avantera Elevate, so we use Elevate's label as the worked example. The labeling rules come from the FDA's regulations for dietary supplement labels, 21 CFR 101.36 and 101.4, read in their current form on eCFR. We read the Elevate capsule label from the Supplement Facts card on the Elevate product page on October 29, 2026. The examples of matching a label to a study use ginkgo and Panax ginseng, which aren't in Elevate, and the trials are linked in the Sources list.

The nootropic label decoder

Every line on a nootropic's Supplement Facts panel answers one question. This table shows what each part of a label line tells you and what to check next.

On the label	Example	What it tells you	What to check
Serving size	2 capsules	Every amount on the panel is for this many capsules or gummies, not for one.	How many you'd take in a day, and how many servings are in the bottle.
Plant and plant part	Bacopa (Bacopa monnieri) leaf extract	The species and the part of the plant it came from.	Whether it's the part the research used (leaf, root, fruiting body).
Extract or powder	"root extract" or "root powder"	A powder is the dried plant, ground. An extract has been concentrated with a solvent and dried.	Whether a ratio or a standardization is printed with it.
Milligram amount	300 mg	The weight of the ingredient as listed. For a dried extract, it's the weight of the extract.	Whether it's an extract weight, a compound weight or a blend total.
Extract ratio	10:1	About how much raw plant went in per unit of extract. 10:1 means roughly 10 parts plant to 1 part extract.	Multiply the extract weight by the first number to get the raw plant amount.
Standardization	std. 50% bacosides	The share of a named marker compound in the extract, set by the manufacturer's specification.	Multiply the extract weight by the percentage to get the marker amount.
"Equivalent to"	equivalent to 500 mg	The raw plant amount the extract was made from, not the weight in the serving.	Compare it only with another raw-equivalent figure.
Proprietary blend	Focus Blend, 600 mg	The total weight of several ingredients, listed in order of weight, without each one's amount.	Whether any single ingredient's amount is printed.
% Daily Value	† Daily value not established	No official daily value exists for that ingredient. Most nootropic ingredients have none.	Nothing is wrong. The symbol is required.
Trademark symbol	BioPerine®	A branded ingredient from a named supplier.	If a study used a branded extract, whether the label names the same one.
Other ingredients	Vegan capsule, rice extract blend	The capsule shell and inactive ingredients that help make the product.	Allergens, sweeteners and fillers you'd rather avoid.

A label line that gives the plant part, the extract weight, the ratio and the standardization tells you four separate things, and each one is checkable.

Why does a nootropic label print the extract weight and not the plant weight?

The FDA's dietary supplement labeling rule sets this. For ingredients without an official daily value, which covers most nootropic herbs and mushrooms, the amount on a Supplement Facts panel is "the weight of the other dietary ingredient listed and not the weight of any component, or the source, of that dietary ingredient." For an extract dried to a powder, the weight shown is the weight of the dried extract (21 CFR 101.36(b)(3)(ii) and (ii)(C)).

So when a label lists a 10:1 lion's mane extract at 50 mg, 50 mg is what's in the serving, and the 500 mg of mushroom it came from is the source. The rule lets a label list marker compounds under the ingredient (21 CFR 101.36(b)(3)(iii)), and many labels also print the ratio or the source amount. None of it is required. Labels that print it give you more to work with.

The same rule makes botanicals name the part of the plant they come from (21 CFR 101.36(d)(1), referring to 101.4), which is why you see words like "leaf extract" or "root extract" on a Supplement Facts panel.

A label's milligram figure for an extract is the extract's own weight, so a 10:1 extract listed at 50 mg and a raw powder listed at 500 mg start from the same 500 mg of plant.

What does an extract ratio like 10:1 mean on a supplement label?

An extract ratio compares the weight of the raw plant to the weight of the finished extract. A 10:1 extract means about 10 grams of dried plant went into 1 gram of extract. The math to get back to the raw plant is one step: extract weight times the first number of the ratio.

• 50 mg of a 10:1 extract was made from about 500 mg of raw material.
• 100 mg of a 4:1 extract was made from about 400 mg.
• 30 mg of a 20:1 extract was made from about 600 mg.

A ratio describes how much plant went into the extract. Which compounds came out also depends on the plant part and the solvent used to extract it, and the ratio doesn't show those. That's the job of the next number on the line, the standardization. The clearest labels give both.

In short: multiply by the ratio to get the raw plant, and read the standardization to get the compounds.

What does "standardized to 50% bacosides" mean?

Standardization means the manufacturer sets the level of a marker compound in the extract and tests each batch for it. The marker is a compound that research on that plant commonly measures. It's named on the label with its share of the extract.

The math is the extract weight times the percentage. On the Avantera Elevate capsule label, bacopa leaf extract is 300 mg, standardized to 50% bacosides. That works out to 150 mg of bacosides per two-capsule serving. Other standardizations on the same label:

• Rhodiola rosea root extract, standardized to 3% salidrosides
• Turmeric root extract, standardized to 95% curcuminoids
• Organic lion's mane extract, standardized to 30% polysaccharides

Two things to keep in mind when you compare standardizations. First, the compound has to match: a bacopa extract standardized for "saponins" and one standardized for "bacosides" aren't stating the same thing. Second, the percentage belongs to the extract, not to the whole serving, so do the multiplication before you compare.

Elevate supports acetylcholine, your brain's memory messenger, two ways: CDP-choline and bacopa.* 200 mg of CDP-choline (citicoline) is a source of choline the body uses to make acetylcholine, and 300 mg of bacopa monnieri (standardized to 50% bacosides) is an herb studied for how it supports acetylcholine activity.*

Elevate's bacopa line, 300 mg standardized to 50% bacosides, works out to 150 mg of bacosides per serving.

What does "equivalent to" mean on a nootropic label?

"Equivalent to" gives the raw plant amount an extract was made from. It's the ratio math done for you. A line that reads "10:1 extract, equivalent to 1,000 mg" describes 100 mg of extract made from 1,000 mg of plant.

The rule for comparing is to keep like with like. An "equivalent to" figure compares with another "equivalent to" figure, and an extract weight compares with another extract weight. Setting one product's raw-plant equivalent against another product's extract weight mixes two different measurements.

Gummy labels, including our Elevate Sour Gummies, often list botanicals this way. How each Elevate label lists each ingredient is laid out side by side on our Elevate capsules vs Sour Gummies page.

Is the milligram number for caffeine the caffeine or the extract?

It depends on how the label is written, and it's worth checking on any nootropic with caffeine. Some labels list the caffeine itself. Others list a green tea or coffee bean extract by weight and give its caffeine percentage, so you do the math: 500 mg of an extract standardized to 20% caffeine holds 100 mg of caffeine.

The Avantera Elevate capsule label lists the caffeine itself: 95 mg of caffeine from green tea leaf per serving, about what's in a cup of coffee.

A cup of coffee's caffeine, with twice the L-theanine for calm, steady focus.* Each serving pairs 95 mg of caffeine from green tea with 200 mg of L-theanine.

How do you compare a nootropic label to the dose used in a study?

A study's dose is a fact about that study: a specific material, at a specific amount, taken on a specific schedule, by specific people. Before you set a label beside it, check five things.

1. The material. Many trials used one named extract. Ginkgo trials in healthy adults such as Mix 2002 and Kaschel 2011 used the extract EGb 761, and most Panax ginseng trials in healthy young adults used the extract G115 (Kennedy 2001; Reay 2010). When a study names its extract, check whether the label names the same one.
2. The ratio and the standardization. If the paper states them, compare them with the label line. If it doesn't, the comparison stays rough.
3. The basis of the number. Check whether the study reports extract weight or raw-plant weight, and convert the label line to the same basis.
4. The schedule. A single dose tested an hour later and a daily dose taken for 12 weeks answer different questions. The ginseng trials above gave 200 to 600 mg as single doses or daily for 8 days; the ginkgo trials gave 180 or 240 mg a day for 6 weeks.
5. The people. Trials enroll a set group, such as healthy adults 45 to 56 in Kaschel 2011 or adults 60 and older in Mix 2002.

Our review of 20 nootropic ingredients grades how strong the research is for each one.

Five checks come before any milligram comparison: material, ratio and standardization, basis, schedule and population.

What does a proprietary blend hide on a supplement label?

A proprietary blend lists several ingredients under one name and one total weight. Labeling rules let the blend show its total weight and name its ingredients in order of weight, without printing how much of each one is inside (21 CFR 101.36(c)).

So "Focus Blend, 600 mg" followed by six ingredient names tells you the total. It doesn't tell you whether the first ingredient is 500 mg and the other five share the last 100 mg. You can't do the ratio math or the standardization math on an ingredient whose amount isn't printed.

For the herbs and other ingredients without a daily value inside a blend, the label rule requires one number, the total, no matter how many of them there are. Why Avantera dropped blends from Elevate in July 2025 is on our proprietary blends page.

Nine ingredients. Every dose on the label. About $1.78 a day. Avantera Elevate lists all nine ingredients and every dose on the label, with no proprietary blends, and every batch is third-party tested. The certificates of analysis are on our quality page.

What does "Other ingredients" mean on a nootropic label?

The "Other ingredients" line lists what isn't a dietary ingredient: the capsule shell, sweeteners, colors, and processing aids that help powders flow through filling machines. Check it for allergens and anything you avoid. The Avantera Elevate capsule label lists two: a vegan capsule (hydroxypropyl methylcellulose) and Nu-MAG, a rice extract blend that is an inactive processing aid, not a blend of active ingredients.

What can't a nootropic label tell you?

• Whether the bottle matches the label. That's what a certificate of analysis is for: a lab report on a production batch. How to read one, field by field, is in our guide to reading a supplement certificate of analysis.
• How the extract was made. The solvent and process usually aren't on the panel. A brand can tell you if you ask.
• What research found on each ingredient. A label is a statement of contents. For the research behind each ingredient, see our review of 20 nootropic ingredients.

How to read the Avantera Elevate label

We read the Avantera Elevate capsule label from the Supplement Facts card on the Elevate product page on October 29, 2026. Here is each line, with what kind of line it is.

Ingredient, as listed	Amount per serving	Kind of line	What the line tells you
Bacopa (Bacopa monnieri) leaf extract, std. 50% bacosides	300 mg	Standardized extract	50% of the extract is bacosides
Rhodiola (Rhodiola rosea) root extract, std. 3% salidrosides	300 mg	Standardized extract	3% of the extract is salidrosides
CDP choline (citicoline)	200 mg	Single compound	The weight is the compound itself
L-theanine	200 mg	Single compound	The weight is the compound itself
Turmeric (Curcuma longa) root extract, std. 95% curcuminoids	100 mg	Standardized extract	95% of the extract is curcuminoids
Caffeine from green tea (Camellia sinensis) leaf	95 mg	Single compound, source named	The weight is the caffeine, not the tea extract
Organic lion's mane extract (Hericium erinaceus), std. 30% polysaccharides, 10:1 extract derived from 500 mg lion's mane	50 mg	Ratio and standardized extract	Made from 500 mg of lion's mane; 30% of the extract is polysaccharides
Ginger (Zingiber officinale) root extract	30 mg	Extract	Root extract by weight
BioPerine® black pepper (Piper nigrum) fruit extract	5 mg	Branded extract	A named supplier's black pepper extract

Serving size is two capsules, with 28 servings per bottle, and every ingredient carries the "Daily value not established" symbol.

The lion's mane line is the one most often misread. Its 50 mg is the weight of a 10:1 extract, so it was made from 500 mg of lion's mane (the fruiting body, per our lion's mane page), standardized to 30% polysaccharides. Read on the same basis, a 500 mg lion's mane powder and Elevate's 50 mg of 10:1 extract start from the same amount of mushroom. The lion's mane change in May 2026, from 100 mg of powder to this extract, is on our lion's mane page, and every Elevate dose set beside the research is on our dosage page.

Frequently asked questions

How do you read a nootropic label?

Start with the serving size, since every amount is per serving. Then, for each herb or mushroom, find three things: the extract weight in milligrams, the extract ratio (such as 10:1) and the standardization (such as 50% bacosides). Check whether any ingredients sit inside a proprietary blend without their own amounts, and read the "Other ingredients" line for anything you avoid.

What does 10:1 extract mean?

A 10:1 extract was made from about 10 parts raw plant for every 1 part of finished extract. Multiply the extract weight by 10 to get the raw plant amount: 50 mg of a 10:1 extract was made from about 500 mg of raw material.

What does "equivalent to" mean on a supplement label?

It gives the raw plant amount the extract was made from, not the weight of extract in the serving. "10:1 extract, equivalent to 1,000 mg" describes 100 mg of extract. Compare it only with another raw-equivalent figure.

What does standardized extract mean?

A standardized extract has a set share of a named marker compound, checked batch by batch. Multiply the extract weight by the percentage to get the marker amount: 300 mg of bacopa extract standardized to 50% bacosides works out to 150 mg of bacosides.

Why don't supplement labels show the raw herb weight?

FDA labeling rules set the amount on a Supplement Facts panel as the weight of the ingredient listed, not of its source, and for a dried extract that's the weight of the extract (21 CFR 101.36). A label can add the ratio or the raw-plant equivalent, but it isn't required to.

How can you tell if a nootropic matches the dose in a study?

Check five things: the material the study used (often a named extract), its ratio and standardization, whether the study reports extract or raw-plant weight, the schedule (single dose or daily, and for how long) and who took part. Milligrams alone can't tell you whether two amounts are comparable.

Why does Avantera Elevate's label list lion's mane at 50 mg?

Because the label lists the weight of the extract. Elevate's lion's mane is 50 mg of a 10:1 extract, made from 500 mg of lion's mane and standardized to 30% polysaccharides.

Is the lion's mane in Avantera Elevate 100 mg?

Not since May 2026. The current Elevate label lists 50 mg of a 10:1 lion's mane extract, made from 500 mg of lion's mane and standardized to 30% polysaccharides. The 100 mg figure describes the earlier formula, which used 100 mg of lion's mane powder.
