Most banned substance conversations focus on the finished product: the thing an athlete holds in their hand. But contamination risk doesn’t start there. It starts with ingredients.
Most supplement certification programs screen around 290 banned substances. TruShield™ Certified covers 480+, and that standard now extends to certified ingredients. ReDaxin™ and AstaReal® Astaxanthin softgels are the first ingredient inputs to complete the process.
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. TruShield™ Certified is closing that upstream gap by extending its 480+ substance panel to certified ingredients.
Two ingredients have already cleared the bar:
- ReDaxin™ from RedLeaf Biologics, and
- AstaReal® Astaxanthin softgels from AstaReal.
Together, they show what ingredient-level certification looks like in practice, and why it matters for brands that want documentation athletes can actually rely on.
This article focuses on TruShield™ Certified’s process to provide verification for banned substance free raw materials and ingredients, taking quality assurance to a new level. Subscribe to PricePlow’s TruShield™ Certified notifications, and let’s get into it:

Finished Product Testing Alone Isn’t Enough
When something goes wrong with a supplement (a contaminant triggers a positive drug test, a brand faces a recall), manufacturers often get blamed, but the investigation just as often traces back to an ingredient. Brands typically require their ingredient suppliers to provide certificates of analysis, but COAs aren’t banned substance screens. They confirm what’s in the product, not what’s been ruled out against a 480-substance prohibited list.
TruShield™ Certified brings WADA-level banned substance testing to supplements. Led by Lori Bestervelt (who created NSF 173 & Certified for Sport), it tests for 400+ banned substances using the same lab sports organizations trust when athletes test positive.
Ingredient suppliers are rarely required to meet the same banned substance testing standards as the brands purchasing from them, meaning the inputs entering a formula may never have been screened against a prohibited list at all. That asymmetry dumps all the risk downstream onto the brand, even when the source of the problem was upstream in the supply chain. One contaminated ingredient lot can compromise an entire production run and take a brand’s reputation with it.
TruShield™ Certified addresses this by certifying ingredients batch-specifically against its full banned substance panel. Brands get documented proof (a batch-specific certification record) showing that their ingredient inputs were screened against the same comprehensive banned substance panel as their finished products.
480+ Substances: What the Coverage Gap Actually Looks Like
Most industry-standard certification programs screen roughly 290 banned substances. That covers common categories, but it leaves out entire drug classes that appear on the WADA Prohibited List: glucocorticoids, HIF stabilizers (a newly recognized category other programs haven’t incorporated yet), and other compounds that tested athletes are held strictly accountable for.
TruShield™ tests for 480+ substances, approximately 180 to 190 more than the typical alternative. That gap traces directly to TruShield™’s origins: a program built by WADA-experienced anti-doping scientists through Sports Medicine Research Testing Lab (SMRTL), one of only two WADA-experienced anti-doping laboratories in the United States. Unlike bundled certification programs that fold banned substance testing into a broader quality checklist, TruShield™ focuses exclusively on what tested athletes actually need — a comprehensive, lot-specific screen against every prohibited compound their careers depend on, in the very product they use.
WADA’s 2026 prohibited list is now in effect. New banned substances include BAM15, flmodafinil, and fladrafinil–all found in supplements. One contaminated product can end an Olympic career. Testing depth matters more than ever.
At picogram-level detection sensitivity, those 180+ uncovered substances aren’t a footnote. They’re categories where a false sense of security carries real career consequences. What sets SMRTL apart from traditional supplement testing laboratories is its foundation in human anti-doping science rather than routine supplement quality assurance. Most labs serving the dietary supplement industry are built around quality control measures like identity, potency, microbiological screening, heavy metals, and shelf-life stability. Those tests matter for product quality, but they’re a different discipline from the analytical rigor anti-doping applications demand. SMRTL analyzes human athlete blood and urine samples for Olympic, professional, collegiate, and elite amateur sports programs. That means TruShield’s scientific framework was developed around the same high-stakes standards used to protect athlete eligibility and competitive integrity, not adapted from a quality control checklist.

ReDaxin™: The First Certified Ingredient
In November 2025, ReDaxin™ from RedLeaf Biologics became the first ingredient ever to earn TruShield™ Certified status.
ReDaxin™ is a patented red sorghum extract containing rare 3-deoxyanthocyanidins, a class of polyphenols not commonly found in sports nutrition ingredients. It’s sourced from a proprietary variety of red sorghum grown in Kentucky and is non-GMO, self-affirmed GRAS, and certified in powder form. A 2025 study published in the Journal of Strength and Conditioning Research found that supplementation produced faster rates of strength recovery after eccentric exercise compared to placebo at both high and low doses,[1] though researchers observed no significant effects on muscle swelling or perceived pain.
That clinical context matters for where ReDaxin sits in the market. Active nutrition and sports performance carry the highest scrutiny under drug-testing programs, which means brands operating in these categories face the strongest demand for supply chain documentation. Certifying at the ingredient level, batch-specifically, against a 480+ substance panel gives those brands the upstream evidence they need before production even begins.
TruShield’s Lori Bestervelt said at the time of certification: “ReDaxin represents exactly the kind of ingredient TruShield™ Certified was designed for: science-driven, rigorously validated, and built for athletes who cannot afford uncertainty. We are proud to certify an ingredient that aligns with our mission to protect athletes and elevate the integrity of sports nutrition.”
Jordan Raphel, Director of Clinical Product Development at RedLeaf Biologics, added: “Achieving TruShield™ Certified status is a milestone for ReDaxin and for the athletes and brands who rely on clean, trustworthy performance ingredients. We built our U.S.-grown ReDaxin for real results, and now it carries the elite level of trust athletes and active nutrition users can feel confident using.”
AstaReal® Astaxanthin: Certified Across Three Dosage Formats
In March 2026, AstaReal® Astaxanthin softgels from AstaReal earned TruShield™ Certified status across three dosage formats: 4mg, 6mg, and 12mg. Each lot was certified individually, with lot numbers and expiration dates listed publicly on TruShield’s certified products registry.
AstaReal® Astaxanthin is the most clinically studied branded astaxanthin ingredient worldwide, with more than 70 human studies covering muscle endurance and recovery, eye health, skin health, and healthy aging. The ingredient is derived from the freshwater microalga Haematococcus pluvialis, cultivated in a closed indoor system to limit contamination exposure, and manufactured in both the United States and Sweden.
Astaxanthin has traditionally been positioned in general wellness and healthy aging categories, but its sports nutrition relevance has grown as researchers study its role in recovery and endurance. Formulators have increasingly looked to it as a non-stimulant option that fits the active lifestyle market without pushing into traditional stimulant-based territory. Certifying three dosage formats through TruShield™ gives brands a ready-to-use finished format with banned substance documentation already in place, cutting development friction for anyone wanting to bring a verified astaxanthin product to tested athletes.
Karen Hecht, Vice President of Science at AstaReal, said: “Achieving TruShield™ Certified status for these AstaReal® Astaxanthin softgels marks an important step for brands looking to deliver clean, performance-focused products with speed and confidence. By offering a ready-to-launch, finished format built around AstaReal’s clinically supported astaxanthin, brands can introduce a premium product athletes and active consumers can trust from day one.”
Bestervelt on the fit: “AstaReal® Astaxanthin softgels represent exactly the type of finished product TruShield™ Certified was created to support: one that is science-backed, rigorously tested, and designed for athletes who demand absolute confidence in what they take. We are proud to certify a turnkey solution that helps brands bring trusted, high-integrity sports nutrition products to market.”
What Ingredient Certification Means for Brands
Both certifications point toward the same shift: ingredient integrity is becoming a procurement question, not just a finished-product QA step.
Lori Bestervelt, Ph.D., creator of the NSF 173 standard, and Thane Campbell from SMRTL introduce TruShield Certified, testing supplements for over 400 banned substances using WADA-level methodologies on Episode #193 of the PricePlow Podcast.
When a certified ingredient like ReDaxin or AstaReal® Astaxanthin goes into a formula, brands can document that the input was batch-specifically screened against 480+ prohibited substances by a WADA-experienced laboratory before production started. That documentation matters in several directions:
- Athlete confidence: Teams, coaches, and sports dietitians working with tested populations need more than general quality claims. A certified ingredient gives them a verifiable audit trail at the source.
- Faster time to market: AstaReal’s certified finished-dose softgels let brands bring a TruShield™-verified product (such as in vitamin packs) to market without building the testing process from scratch.
- Reputation protection: Contamination incidents tied to an ingredient supplier are a brand’s problem regardless of where the fault originated. Sourcing certified ingredients limits that exposure before it becomes one.
- Reduced liability: At picogram detection sensitivity, a single undetected prohibited substance can cost an athlete years. Every additional layer of documentation between a brand and that outcome has real value.
For brands thinking about how to differentiate in a crowded sports nutrition market, ingredient-level certification through a WADA-caliber lab is one of the more defensible signals available.
Protecting Athletes from the Ground Up
Finished product certification is meaningful. But if the ingredients going in haven’t been held to the same standard, there’s a gap in the story. ReDaxin and AstaReal® Astaxanthin are two examples of what it looks like to close that gap, and they’re likely not the last.
