We formulate to the literature, not the margin.
Most supplement brands are marketing companies with a formulation as an afterthought. Xeren Labs works in the other direction — the research dictates the dose, and the dose dictates the product.
No Proprietary Blends
Every active ingredient is listed with its exact dose. Proprietary blends exist to hide underdosing — we have nothing to hide.
Doses Match the Literature
Each formulation is built to the dose ranges used in the published clinical trials for that compound, not the cheapest dose that lets a label make a claim.
Third-Party Verified, Every Batch
No batch ships without an independent Certificate of Analysis confirming identity, potency, and screening for heavy metals and microbial contamination.
Bioavailable Forms, By Default
Where a more absorbable form of a compound exists and is commercially viable, we use it — even when the cheaper, less-absorbed form is more common in the category.
