About MIJA
Wellness, considered from every angle.
MIJA creates intelligent, practitioner-led formulas for the whole body. Across daily nutrition, skin and hair care, and transdermal wellness, each format is chosen for its distinct purpose and place in real life.
One body. Multiple forms.
The right support does not always arrive the same way.
MIJA works across formats because wellness is interconnected. The delivery changes according to the purpose: concentrated whole-food nutrition, direct topical mineral use, or lipid-rich care for skin, scalp, and hair.
02Transdermal
Through the skin
Targeted mineral support in a direct, approachable format that fits naturally into real routines.
03Skin + hair
Across the surface
Clinically studied actives and nutrient-rich oils for renewal, barrier support, scalp, and hair.
The MIJA standard
Intelligence in every decision.
The difference is not an overwhelming ingredient count. It is knowing what belongs in a formula, why it is there, and how the complete product should work in daily life.
01
Practice before trend
Formulation begins with practitioner insight and real-world patterns—not the ingredient of the moment.
02
Every ingredient earns its place
Ingredients are chosen for a meaningful role within the complete formula, never simply to expand the marketing story.
03
Whole plants + modern actives
Nutrient-dense whole foods and botanicals work alongside clinically studied forms where they improve performance.
04
The right format for the job
Powder, oil, or spray: delivery follows the product’s purpose and the way people will actually use it.
From practice to product
Built from what people actually need.
MIJA began with registered dietitian nutritionist Sarah Koszyk’s decades of work with real clients. That experience created a real-world understanding of how nutrition, lifestyle, and daily habits intersect—and where the wellness industry too often favors excess, novelty, or label decoration over intelligent formulation.
Today, that practitioner foundation extends across nutrition, topical care, and purposeful delivery systems designed around the whole body.
