Our Story

MIJA is a California-based wellness company. Our team combines over decades of experience in the food, beauty, and wellness industry. 

Why wellness? Everything from our skin and hair, to our energy and mood, begins and ends with the functional wellness of our body. Without proper nutrition and care, even the best serums and workouts won't go very far. Science indicates that the nutrients we provide our bodies are fundamental for every aspect of our wellness from long, flowing locks and restful sleep, to a beautiful, glowing complexion. We understand it's a challenge to get all these nutrients daily. So we created easy-to-take, clean, superfood-powered solutions backed by clinical research.

Our first product is Superstar -- an essential daily supplement made from 100% certified-organic, plant-based, single-sourced ingredients designed to fill the universal nutritional gaps and dietary shortfalls in the modern diet. As one of the nation's leading registered dietitian nutritionists, Sarah drew upon her extensive client work as data points to ensure our supplement was formulated with precise ratios to provide all the essentials for optimized health.

Our mission is 


Here's how we do it: 


Quality is front and center when it comes to sourcing for us. From lush goldenberries to vibrant turmeric, we carefully source all of our ingredients. Guaranteeing single-sourced origin of every single component in our formula. We work closely with local Californian growers and independent small farms around the world that incorporate organic, eco-sustainable, bio-dynamic practices to ensure ideal conditions from nutrient-rich soil to perfectly timed harvests so the ingredients we bottle are at their peak freshness and fulfill their nutritional potential.

To date, our formulas are 100% certified-organic. Our single-sourced, direct-from-the-soil, plant material contains more active compounds and nutrients than other leading supplements.

All raw plant material is lab-tested to ensure the highest of quality, nutritional value, and purity. The labs we use also work with professional sports teams for nutritional testing, so we're able to use cutting-edge tests to test for everything from radiation exposure and heavy-metal contamination to any residue impurity, which is not included in most labs for purity testing.


We work with each ingredient on an individual level to ensure that our extraction process is customized to guarantee that the full spectrum of nutrients is intact when they're bottled.

Our proprietary extraction method uses no chemical solvents and does not damage the integrity of phytocompounds or micronutrients in the plant material. In some cases, our extraction process may amplify the expression of carefully selected nutrients to increase the concentration of rarer nutrients.

Finally, our formula is tested for bio-availability to make sure the nutrients we extracted remain stable and can be fully absorbed by the body. Therefore, verifying that we select only the most biologically compatible forms of nutrients that the body can efficiently utilize.

All active ingredients are lab-tested, and clinically backed. Additionally we have a panel of peers -- fellow board-certified registered dietitians and nutritionists, who taste, experience, and approve our products.


Sarah Koszyk, MA, RDN


Our co-founder, Sarah Koszyk, is a board-certified, registered dietitian nutritionist whose clientele includes Silicon Valley executives and professional athletes. She's served on the academic board of dietitians responsible for vetting many supplements on the market today, and realized that there was a significant lack of oversight into the quality of ingredients and integrity of the overall formulas. Upon realizing that the wellness industry was more concerned with the quality of a face oil than the quality of nutrients actually being ingested -- Sarah decided to advocate for change in the way consumers valued their health.

Building upon her vast experience as a leading registered dietitian nutritionist, and with her connections to the top performance labs, food scientists, and farmers, we were able to fulfill our mission of delivering optimal wellness from within by sourcing the freshest ingredients of the finest quality, meticulously tested for purity, that undergo cutting-edge extraction processes and are backed by clinical research.

MIJA means “my daughter”

in Spanish and is colloquial for “mi hija.”

MIJA used in everyday conversation as a term of endearment. As a female-founded business, it also speaks to our universal experience of women sharing traditions through the generations. We love the casualness, sincerity, and intimacy of the name and it reminds us of youth, family, love, and bliss, which is what we want all MIJA products to inspire and feel in people.
