SCIENTIFIC RESEARCH

Science Behind Our Ingredients

MESA regularly reviews scientific literature related to the ingredients used in its products, and shares that review here. Our aim is to present relevant research responsibly and transparently.

How to read this library

Evidence level describes the strength of the available published research.
Formulation relevance describes how closely that research matches the ingredient's actual use in MESA products.
Scientific literature provides context and does not automatically establish efficacy or clinical claims for MESA's finished products.

Scientific publications presented here concern individual ingredients or related preparations and should not be interpreted as clinical evidence for the finished MESA product unless explicitly stated.

Scientific Literature

Why is this ingredient used?

An ingredient may be included based on its established use, known properties, formulation purpose, or broader scientific interest even when clinical evidence for a specific outcome remains limited. The evidence level shown here describes the strength of the published evidence for the research question reviewed — it does not mean that the ingredient has no known properties or that its use in a formulation is scientifically meaningless.

What the evidence means

Evidence levels describe the strength and relevance of the available scientific literature. They should not be interpreted as a rating of the ingredient itself or as a direct clinical claim about MESA products.

Karsch-Völk M, Barrett B, Kiefer D, Bauer R, Ardjomand-Woelkart K, Linde K — Cochrane Database of Systematic Reviews

Whether Echinacea preparations prevent or treat the common cold, compared to placebo.

Evidence Level: Limited
Formulation Relevance: Indirect

Indirect relevance means the available research is related to the ingredient or a similar use, but does not directly evaluate MESA's finished product or its exact formulation.

Systematic Review · 2013

Vitamin C for preventing and treating the common cold

Hemilä H, Chalker E — Cochrane Database of Systematic Reviews

Whether regular or therapeutic vitamin C supplementation prevents or shortens the common cold.

Evidence Level: Moderate
Formulation Relevance: Related

The available research is relevant to the ingredient or a comparable application, but it still does not constitute clinical evidence for the finished MESA product.
