The supplement industry operates in a regulatory grey area defined by proprietary blends and hidden synthetic excipients. The Clean Label Index exists to move consumer choice beyond marketing claims by establishing a strict, machine-readable standard of technical purity.
A score of 10.0 on our index represents absolute, uncompromised integrity in manufacturing. We do not curve grades based on industry averages. Instead, our fixed baseline for perfection is anchored to the highest-tier, small-batch manufacturing protocols: triple-distilled solvent extraction, zero-excipient encapsulation, and non-leaching vessel containment.
Products are audited against this agnostic baseline and receive a numerical deduction for every identified synthetic additive, harsh solvent, or packaging failure.
Active compounds must be extracted without the use of toxic solvents like hexane or harsh alcohols. The index prioritizes triple-distilled water and CO2 extraction protocols. Any presence of chemical solvent residue results in a severe grade penalty.
A pure supplement is compromised if housed in a volatile vessel. Platinum Tier products (9.0 and above) must utilize UV-protective amber or miron glass. Plastic bottles (PET/HDPE) incur an automatic 1.5-point deduction due to the risk of microplastic and endocrine-disruptor leaching over time.
The total exclusion of non-nutritive synthetic fillers is required. We scan strictly for Magnesium Stearate, Silicon Dioxide, Titanium Dioxide, and the intentionally vague term "Natural Flavors." Clean formulations must rely on organic alternatives like acacia gum or zero excipients entirely.
We audit the specific molecular form of the vitamin or mineral. For example, synthetic Cyanocobalamin (B12) fails our biocompatibility standard because it requires hepatic conversion and cyanide filtration. The index mandates bioactive, immediate-release forms like Methylcobalamin or Adenosylcobalamin.
A label claim is not an audit. Products must have verifiable Third-Party Certificates of Analysis (COA) confirming that heavy metal loads (Lead, Arsenic, Cadmium, Mercury) and microbial limits fall strictly below pharmaceutical safety thresholds.
