The Verdict
Life Extension edges it on our rubric, 87 to 86 on our 0-100 execution score, and holds our Top Pick badge; Pure Encapsulations holds our Best Quality badge. Transparency ties at 23. Pure Encapsulations wins dosing and form 25 to 22 on the micronized form and purity verification 22 to 19 on its testing program; Life Extension wins value 23 to 16, which is the largest single pillar gap and the reason it finishes ahead. In our view both clear the bar our profile actually sets, which is a brand that will show you a certificate of analysis in a category where our profile says quality control is poor.
After that the difference is about fifteen cents a day against a micronized form and a hypoallergenic formulation, and our notes say Pure Encapsulations is the brand most commonly stocked by integrative and functional medicine clinicians, which is worth something if you want consistency with what your provider already recommends. Two things are not our call and should not be decided from a scorecard. Our profile says to skip DHEA if you are under 40, pregnant, breastfeeding, or have any history of hormone-sensitive cancer or liver disease, and it notes DHEA is banned by WADA, the NCAA, MLB, the NFL, and most major sports bodies. Talk to a clinician before starting either product, and if you compete at any level, do not take it.

Why This Comparison Matters
Both of these are single-ingredient 25mg DHEA capsules and they finish one point apart, so this is a comparison about documentation and price rather than about what DHEA does. Whether DHEA is appropriate for you at all is a medical question, and our profile is direct that its strong evidence is confined to diagnosed adrenal insufficiency.
Our profile also says quality control is poor across this category and that you should buy only from brands that publish a certificate of analysis confirming actual DHEA content, which is the lens to read both labels through. Life Extension publishes a certificate of analysis on request, manufactures in NSF GMP-registered facilities, and uses a single-ingredient label with no proprietary blends, at 100 capsules for $11.25. Pure Encapsulations is third-party tested with a certificate of analysis available, is hypoallergenic, and calls out micronization explicitly on the label, at 180 capsules for $47.50. Neither is NSF Certified for Sport, which our notes point out is moot here.
On cost, Life Extension is about $0.11 per day at 25mg and Pure Encapsulations about $0.26. The amount commonly cited in our profile is 25 to 50mg a day in the morning for adults over 40 with low DHEA-S.
Detailed Score Breakdown
DHEA 25 mg
Life Extension
25mg matches the Endocrine Society 2016 trial dose for adrenal insufficiency replacement and the Arlt 1999 NEJM protocol
Life Extension publishes a certificate of analysis on request, manufactures in NSF GMP-registered facilities, has decades of consumer reputation
$0.11/day at the 25mg starting dose ($11.25 for 100 capsules) after a price drop - one of the cheapest defensible options
Single-ingredient label, no proprietary blends, Life Extension publishes monograph-level dose rationale
Life Extension is one of the few mainstream brands that built its reputation on hormone supplementation, so dosing and labeling are tight
DHEA 25 mg (Micronized)
Pure Encapsulations
Micronized 25mg matches the most-studied dose; smaller particle size theoretically improves absorption
Pure Encapsulations is hypoallergenic, uses third-party testing, and publishes COAs through PureFormulas; trusted in clinical-practice channels
$0.26/day at 25mg ($47.50 for 180 capsules) after a price rise; the micronized form and hypoallergenic formulation justify the premium for some buyers
Full disclosure, free-from claims verified, no proprietary blends, micronization explicitly called out
Pure Encapsulations is the brand most commonly stocked by integrative and functional medicine clinicians, useful if you want consistency with what your provider already recommends
How We Compared These Products
Every product in our database is scored on four equally-weighted pillars: dosing accuracy and form quality, purity verification (third-party testing), cost per clinically effective dose (not cost per pill), and label transparency. Each pillar is worth 25 points for a total of 100.
Cost per effective dose is calculated using the clinically studied dose from published research, not the manufacturer's suggested serving. If a product requires multiple servings to reach the dose used in clinical trials, that cost is reflected in the value score.

Frequently Asked Questions
Does either brand publish a certificate of analysis?
Both do, which matters because our profile says quality control is poor across the DHEA category and to buy only from brands that publish a certificate confirming actual DHEA content. Life Extension publishes one on request and manufactures in NSF GMP-registered facilities. Pure Encapsulations is third-party tested with a certificate available and publishes through its practitioner channel. Our purity verification pillar splits that 22 to 19 for Pure Encapsulations.
Which DHEA is cheaper per day?
Life Extension, at about $0.11 per 25mg day against Pure Encapsulations at about $0.26. The bottles are $11.25 for 100 capsules and $47.50 for 180. Our value pillar scores that 23 to 16, the widest gap in this comparison.
What does micronized mean on the Pure Encapsulations label?
It refers to a smaller particle size, which our notes describe as theoretically improving absorption. It is called out explicitly on the label and is why Pure Encapsulations wins our dosing and form pillar 25 to 22. Both products deliver 25mg, the amount our profile cites most often for adults over 40 with low DHEA-S, and whether that dose is right for you is a question for your clinician.
