For over four decades, Pain & Stress Center has stood as a beacon of natural, doctor-formulated health solutions. Founded in 1979 in San Antonio, Texas, by the pioneering Dr. Billie Sahley, Ph.D., C.N.C., PSC broke new ground in orthomolecular medicine—blending brain chemistry insights with nutritional therapy. Alongside Dr. Katherine Birkner, C.R.N.A., Ph.D., C.N.C., the two created revolutionary formulations like Anxiety Control 24®, authored foundational texts on mood, trauma, and nutritional balance, and trained countless professionals in a root-cause, functional medicine approach.

Why the New Name? Why Now?
Health science never stands still—and neither do we. While PSC products remain as clinically validated today as the day they were developed, research has advanced. That’s why we've launched Based Vitality—a fresh brand built on the same scientific rigor and integrity, but with a sharper focus on modern performance and transparency.
We are committed to using only the most proven ingredients, dosed precisely as shown effective in clinical studies. Our labels are fully transparent, so you know exactly what you're getting. It's the best of PSC, reimagined for high-performance living.
The Four Pillars of Health
Based Vitality was not made to replace your diet. It was not made to take short cuts by overstimulating you or drugging you with high amounts of melatonin. Based Vitality is meant to provide minerals, herbs, and amino acids that are not typically found in a normal diet. We want to compliment your diet, not replace it. Thats why we created The Four Pillars of Health. These will be our core four products that help you perform better in life in.
1. Performance
Fuel your stamina, strength, and energy with nutrients shown to work at clinically backed doses.
2. Mental Clarity
Sharpen your focus with clean, nootropic and adaptogenic ingredients that support cognitive function.
3. Stress Resilience
Balance your nervous system and cortisol levels so you stay calm and centered under pressure.
4. Recovery
Sleep deeper, recover faster, and wake ready to bring your best.
Our Core Product Line-Up
To bring these pillars to life, we’re launching four foundational supplements:
· Pre-Workout – Designed for performance and energy.
· Memory & Focus Support – Nootropic support for mental clarity.
· Stress & Mood Support – Calm, balance, and emotional resilience.
· Sleep & Recovery Support – Restorative support for deep sleep and recovery.
PSC Lives On—Refreshed, But Not Replaced
Rest assured, PSC products are not going anywhere. Based Vitality exists under the same umbrella—and carries forward the same principles that made PSC trusted: clinical research, formula integrity, transparency, and education-first care. Whether you're continuing with PSC or embracing Based Vitality, you're supported with real, rooted solutions.
