The Science Behind Our Formulas

Why do clinically meaningful doses matter?

Many supplements include ingredients at “label-friendly” amounts that look impressive but fall below effective levels.

We formulate at doses supported by research so each ingredient can actually perform its intended function in the body.

If it’s included, it’s included for a reason and at the right dose.

What does “Clinical Dosing” actually mean?

Clinical dosing means using ingredient amounts that align with levels studied in peer-reviewed research, chosen by a practicing physician.

We do not formulate around trends, marketing buzzwords, or underdosed blends. Our formulations are built around mechanism, absorption, and measurable physiological impact.

Why don’t we use proprietary blends?

Transparency builds trust.

We disclose the exact amount of every active ingredient so you know precisely what you are putting into your body. No hidden totals. No inflated label claims. No guesswork.

How do you select your ingredients?

Not everything makes the cut.

Every ingredient is hand-selected by a practicing physician, based on clinical relevance, bioavailability, and real-world efficacy. We prioritize forms your body can actually use, at doses that are designed to do something, not just look good on a label.

No fillers. No trends. No unnecessary complexity.

Just ingredients chosen with purpose, backed by experience, and formulated to perform.

How are our formulations different from most supplements?

Most supplements are formulated for marketing appeal rather than physiological effect. A common practice is ingredient spiking, where a brand lists an ingredient on the label but includes it at a dose or in a form that is unlikely to be meaningfully absorbed or utilized by the body.

Ours are built for physiological effect.

We focus on effective dosing, ingredient synergy, and absorption so the formula works as a system rather than a collection of isolated ingredients

Why is ingredient quality as important as dosage?

Dosage determines effectiveness. Quality determines absorption and safety.

We source ingredients that meet high standards for purity and stability so what’s listed on the label is consistent, bioavailable, and dependable.

Developed by a Practicing Physician

Physician Crafted™ was created by Jeffrey Macievic, MD, a board-certified physician anesthesiologist with nearly two decades of experience in clinical medicine and human performance. Over the course of his career, he has witnessed countless patients struggle with preventable health issues-often rooted in nutritional gaps. In today’s world, abundance doesn’t always equal nourishment—leaving many people struggling with energy, recovery, and overall well-being.

Frustrated by the shortcomings of the supplement industry, and a healthcare system more focused on treating disease rather than preventing it, Dr. Macievic set out to create something different through Physician Crafted™, which was founded on his commitment to clean, clinically effective formulas designed to replace what modern, processed diets leave behind. Every product is carefully crafted with synergistic ingredients at clinically backed doses—so you can feel confident you’re getting high quality supplements that deliver the results you deserve.

Creatine: The Energy Molecule Behind Strength, Focus, and Resilience

Creatine is one of the most studied compounds in sports nutrition and human performance. It is not a stimulant and it is not a shortcut. Creatine is a naturally occurring molecule stored largely in skeletal muscle, where it helps regenerate...

Collagen: The Structural Foundation of the Human Body

Collagen is the body’s primary structural protein, forming the framework of skin, cartilage, tendons, ligaments, bone, and connective tissue. Beginning in early adulthood, natural collagen production declines while degradation increases, contributing to reduced skin elasticity, joint stiffness, and diminished tissue resilience. Research shows that hydrolyzed collagen peptides can be absorbed into the bloodstream and may support dermal density, skin elasticity, and joint comfort, particularly when paired with vitamin C, which is required for proper collagen synthesis. Total Collagen provides 15 grams of bovine collagen peptides alongside vitamin C, glucosamine, hyaluronic acid, inulin, and fucoidan to support connective tissue structure, joint function, hydration, and overall structural integrity from multiple biological pathways.

Electrolytes: The Science Behind Hydration, Performance, and Cellular Energy

Electrolytes are not just about hydration — they are essential minerals that regulate fluid balance, nerve signaling, muscle contraction, cardiovascular stability, and cellular energy production. True hydration depends on sodium, potassium, magnesium, calcium, and other trace minerals working together to control how water moves inside and outside the cell. Everyday Electrolytes provide foundational mineral support for daily hydration and metabolic balance, while Performance Electrolytes are structured for higher sweat states and endurance demands, helping maintain plasma volume and neuromuscular function during physical stress. Hydration is physiology — and physiology depends on electrolytes.
