Most banned substance testing focuses on finished products, but contamination risk starts upstream with ingredients. TruShield™ Certified now extends its 480+ substance panel to certified ingredients, with ReDaxin™ and AstaReal® Astaxanthin softgels becoming the first to clear the bar.
A single compromised input can run through an entire production batch, and no amount of end-of-line testing changes what was already baked in. Learn how ingredient-level certification closes the upstream gap and why it matters for brands serving tested athletes in our latest coverage.
When a brand as meticulous as Thorne builds a single-ingredient adaptogen product, the ingredient choice says everything. Thorne Ashwagandha delivers 120mg of Shoden® per capsule, standardized to 35% withanolide glycosides, in a clean one-a-day calming stress support formula.
Clinical data shows Shoden delivers 18x higher bioavailability than standard ashwagandha, with research demonstrating a 59% decrease in anxiety scores and 67% reduction in morning cortisol at this exact dose. Thorne is currently the only consumer brand that built an entire product around Shoden as the sole active -- no blends, no supporting cast, just the extract at a clinically studied dose. Learn why this ingredient selection signals that glycoside-enhanced ashwagandha has officially arrived at the top of the category.
Most cordyceps products test at 0.1 to 1.0mg/g cordycepin. CordyFuel by NuCelium is standardized to 3mg/g, UPLC-verified every batch. That's the dose the research actually used, delivering real energy and endurance support without the guesswork.
Cordyceps has a credibility problem: it has solid science behind it, but most commercial ingredients can't deliver meaningful cordycepin levels. CordyFuel solves that with North American-grown, full-spectrum cordyceps that won the 2025 Cordy Cup for highest verified potency. Read the full breakdown and see why this is the new mushroom standard.
