Extract ratios and standardisation decoded, 10:1 vs 5% explained

Two numbers show up in supplement ingredient lists, and almost nobody distinguishes them.

“10:1 extract.” And “standardised to 5% withanolides.”

They describe different things, they are not substitutes for each other, and a label carrying one while implying the other is the most common way this market misleads without lying.

This article is the decoder. What each number means, what each cannot tell you, how they interact, and which combinations on a label should make you comfortable or suspicious.

This is general information, not medical advice. See a doctor for any health decision, and do not stop prescribed medicines on your own.

What an extract ratio means

“10:1” means ten units of raw plant material went in and one unit of extract came out.

That is all it means. It is a yield statement, not a potency statement.

So “500 mg of 10:1 ashwagandha extract” is described as being equivalent to 5,000 mg of root, and that is where the marketing lives, because “5000 mg equivalent” prints beautifully on a front panel.

Three things that statement does not tell you.

What was extracted. A water extract and an alcohol extract of the same root pull out different compounds. Water-soluble and alcohol-soluble fractions are not interchangeable, and the ratio is identical for both.

Whether the compounds you want survived. A high ratio achieved with heat can concentrate inert matter while degrading the compounds of interest. The ratio still reads 10:1.

And whether the ratio is real. Ratios are easy to assert and hard to verify from the outside. Adding a carrier or a filler to the extract changes the effective ratio and not the claim.

What a standardisation percentage means

“Standardised to 5% withanolides” means the extract was assayed and contains at least 5% of that compound class by weight.

This is a potency statement. It is measurable, reproducible with a stated method, and directly comparable between products.

It is the number that matters, and here is the arithmetic that shows why.

500 mg of extract at 1.5% withanolides delivers 7.5 mg.

300 mg of extract at 5% withanolides delivers 15 mg.

The smaller quantity delivers twice as much of the thing the product is for.

And the 500 mg version will be cheaper, will look more generous, and will have “5000 mg equivalent” on the front if it is also sold as a 10:1.

The two numbers interact, and this is the part people miss

They are not independent, and the relationship is not simple.

A high ratio does not imply a high percentage. You can concentrate the bulk of a plant tenfold and still have a low content of a specific compound, particularly if the solvent was not suited to it.

And a high percentage does not require a high ratio. A targeted extraction can reach a high marker content at a modest ratio.

Which is why the most useful label states both, the ratio tells you the concentration process, the percentage tells you the result, and together they are checkable.

And the least useful label states the ratio alone, prominently, with a “mg equivalent” figure in large type. That combination is a choice, and it is usually a choice to describe the input because the output is not impressive.

The marker compound matters, specifically

Because a percentage of the wrong thing is decoration.

The number that determines potency is different for every herb, and in almost every case there is a bigger, friendlier number available that does not.

Ashwagandha, withanolides. Not “total alkaloids”.

Turmeric, curcuminoids. Not “turmeric extract 500 mg”.

Boswellia, total boswellic acids, and AKBA separately. The 65% total figure can be reached while AKBA stays low, because the other boswellic acids fill the number. A label with 65% and no AKBA figure is honest and uninformative.

Brahmi, bacosides.

Gudmar, gymnemic acids.

Gokshura, protodioscin.

Kalmegh, andrographolides.

Shilajit, fulvic acid, with the test method, because fulvic acid figures vary enormously between methods and this is one of the least standardised measurements in the market.

Milk thistle, silymarin.

Green tea, EGCG, not “total polyphenols”.

Calcium, elemental calcium, not the weight of the salt. 1,250 mg of calcium carbonate is about 500 mg of elemental calcium, and both numbers appear on labels.

The habit worth building: for any ingredient, ask whether the stated number is the one that matters or the one that is easy to reach.

Why the test method belongs on the label

And this is the detail that separates a specification from a slogan.

The same material can assay differently by different methods. HPLC with a specific detection wavelength, a UV spectrophotometric method, and a gravimetric method are not interchangeable, and non-specific methods tend to return higher numbers because they count things the specific method excludes.

So “5% withanolides by HPLC” is a specification. “5% withanolides” is a claim. “High in withanolides” is nothing.

For shilajit in particular, a fulvic acid percentage without a method is close to meaningless, and this is widely exploited.

Reading the combinations

Six label patterns, and what each tells you.

Ratio and percentage both stated, with the method, plus the part of the plant used. This is what a serious product looks like. Comparable, checkable, and it commits the brand publicly.

Percentage with method, no ratio. Fine. The percentage is the number that matters, and the ratio adds context rather than information.

Ratio only, with “mg equivalent” prominent. Usual, and uninformative about potency. Not necessarily bad material, but you cannot tell, which is the point.

“Extract” with a milligram figure and nothing else. You know the weight of powder in the capsule and nothing about its contents.

Whole herb powder, stated honestly as powder. Legitimate, and a different product. Powder is not a concentrate, and a traditional churna is not trying to be one. The problem is only when powder is presented as if it were extract.

And “proprietary blend”, with no quantities at all. Nothing can be compared, nothing can be verified, and we have written separately about what that phrase is usually doing.

The front-panel arithmetic trap

Worth spelling out because it catches careful people.

A front panel says “5000 mg Ashwagandha”.

The back says “Ashwagandha root extract (10:1) 500 mg”, serving size 2 capsules.

So each capsule has 250 mg of extract. The serving has 500 mg, which at 10:1 is described as 5,000 mg of root equivalent.

Three transformations between the front number and what you take, and each one is individually defensible.

Then the question that resolves it all: what is the withanolide content? If it is not on the label, the 5,000 mg figure is describing a process, not a dose.

Practical instructions

For a buyer:

Find the percentage before the milligrams. If there is no percentage, the milligrams are not comparable to anything.

Calculate the active. Extract weight multiplied by percentage. It takes ten seconds and frequently reverses the apparent answer.

Check the serving size before dividing by the pack count, because the front-panel figure is often per serving and not per capsule.

And check the part of the plant, which is a separate line and the one most often missing.

For a brand owner:

Print the percentage, the marker, the method and the part used. It costs nothing, it makes you comparable to a serious buyer, and the commitment is the point.

Specify all four in a dated purchase specification, and require a finished-product assay per batch.

And if your current label states a ratio and no percentage, find out your own percentage before a customer or a buyer does. Some brands discover at that moment that they have been selling a 1.5% product described as 10:1 for two years.

The short version

1. Two different numbers describing two different things
2. “10:1” is a yield statement, ten units in, one unit out
3. It says nothing about potency
4. It does not say what was extracted; water and alcohol pull different compounds
5. It does not say whether the compounds survived the process
6. And ratios are easy to assert, hard to verify from outside
7. A standardisation percentage is a potency statement, and measurable
8. 500 mg at 1.5% delivers 7.5 mg; 300 mg at 5% delivers 15 mg
9. The smaller quantity delivers twice as much
10. And the bigger one is cheaper and looks more generous
11. A high ratio does not imply a high percentage
12. A high percentage does not require a high ratio
13. The best labels state both, plus the method and the plant part
14. The least useful state the ratio alone with “mg equivalent” in large type
15. That is a choice to describe the input because the output is unimpressive
16. The marker compound differs by herb and must be the right one
17. Withanolides, curcuminoids, bacosides, gymnemic acids, protodioscin
18. Boswellia needs AKBA, not just 65% total boswellic acids
19. Shilajit needs fulvic acid with the method stated
20. Green tea means EGCG, not total polyphenols
21. Calcium means elemental calcium, not the salt weight
22. Always ask: is this the number that matters, or the one easy to reach?
23. Methods are not interchangeable, and non-specific ones read higher
24. “5% by HPLC” is a specification; “5%” is a claim; “high in” is nothing
25. Ratio plus percentage plus method plus part = a serious product
26. Percentage with method and no ratio is fine
27. Ratio only is uninformative, not necessarily bad
28. Honest whole-herb powder is legitimate and a different product
29. “Proprietary blend” cannot be compared with anything
30. Front-panel 5000 mg can be three transformations away from your dose
31. Buyers: find the percentage first, then calculate, then check serving size
32. And check the plant part, the line most often missing
33. Brand owners: print percentage, marker, method and part
34. Specify all four and require a finished-product assay per batch
35. And find out your own percentage before a buyer does
