Active ingredient testing verifies the potency and identity of the actives in a supplement, confirming the product matches its label claims. Advanced Laboratories runs validated, accredited potency analysis with a 5-day turnaround and transparent pricing for supplement, food, and nutrition manufacturers nationwide.
Verify the ingredients that define your product.
As formulations grow more complex and label-claim scrutiny tightens, active ingredient testing confirms your actives are present at the levels your label promises. Whether you’re testing raw materials, in-process blends, or finished products, we deliver reliable results with responsive service and clear communication — and we validate new methods continually as the industry shifts.
Validated Potency Testing by Ingredient
Amino Acid Testing
We run amino acid analysis by HPLC (High-Performance Liquid Chromatography) across powders, capsules, tablets, and liquids, verifying label claims, confirming formulation consistency, and checking ingredient integrity. Amino acids anchor sports nutrition, recovery products, protein blends, and wellness formulas, where accurate free-amino-acid profiling protects your claims.
Common applications include:
- Essential amino acid (EAA) products
- Branched-chain amino acid (BCAA) formulations
- Pre-workout and recovery supplements
Caffeine Testing
Confirm caffeine content where small variations carry real consequences for performance, labeling, and the customer experience. We test caffeine in powders, capsules, tablets, and liquids.
Caffeine testing helps you:
- Confirm label-claim accuracy
- Hold batch-to-batch uniformity
- Catch potency drift over shelf life
- Reduce the risk of over- or under-dosed products
Creatine Testing
Test the creatine your label promises. Creatine leads the sports nutrition market right now, which makes independent potency testing a strong trust signal for your brand. We cover powders, capsules, tablets, liquids, and gummies — from monohydrate to pre-workout blends, performance formulas, ready-to-drink products, and gummy supplements.
Protein Testing
Measure total protein with a method built for accuracy. We run protein analysis on a LECO analyzer using the Dumas combustion method: the sample combusts at high temperature, nitrogen-containing compounds convert to measurable gases, and the instrument calculates protein from nitrogen content using the appropriate conversion factor.
Compared to traditional wet chemistry, Dumas combustion runs faster and automates more of the process, giving you repeatable protein results across supplement, food, and nutrition products.
Protein testing helps you:
- Verify nutrition-facts panels
- Confirm product consistency
- Support your quality-assurance program
- Detect formulation deviations early
- Strengthen consumer confidence
More Validated Supplement Actives
Beyond the featured actives, we currently run validated methods for these ingredients and formats:
- Berberine HCl — powders, capsules, tablets, liquids, softgels, and gummies
- Chlorogenic Acids — powders, capsules, tablets, liquids, and gummies
- Curcuminoids — powders, capsules, tablets, liquids, and gummies
- Melatonin — powders, capsules, tablets, bi-layer (time-release) tablets, liquids, softgels, and gummies
Watch this list grow. We validate new active-ingredient methods on a regular basis to keep up with emerging market trends, shifting regulatory expectations, and customer demand. If you don’t see your ingredient, reach out, and we’ll tell you where it stands — available now, in development, or a candidate for future validation.
Beyond Potency: Complete Supplement Testing Support
Pair active-ingredient testing with the rest of your quality program. Potency is only one piece — many of our clients also run:
- Heavy metal testing by ICP-MS (Inductively Coupled Plasma Mass Spectrometry)
- Pesticide residue testing
- Microbiology testing
- Identity testing by FT-IR (Fourier-Transform Infrared) or HPTLC (High-Performance Thin-Layer Chromatography)
- Stability and shelf-life support

Supplement Potency FAQ
Can You Test Finished Products + Raw Materials?
Yes. We test both raw materials and finished products across powders, capsules, tablets, gummies, softgels, and liquids.
What If My Active Ingredient Isn’t Listed?
We validate new methods regularly. Reach out and we’ll let you know whether your ingredient is available now, in development, or a candidate for future validation.
What Is HPLC?
HPLC (High-Performance Liquid Chromatography) is an analytical method that separates and measures compounds such as caffeine, amino acids, and other active ingredients, so we can confirm how much of each is present in your product.
