Three practitioners.
Which is right for you?
Dr. Liz Rychlik N.D.
Naturopathic medicine is the starting point if you’re experiencing chronic health concerns, hormonal imbalances, fatigue, digestive issues, or simply want evidence-based natural care to complement your conventional medical treatment. Dr. Liz Rychlik integrates clinical nutrition, botanical medicine, functional testing and lifestyle medicine to find and address root causes rather than managing symptoms. Available at both Tight Clinic locations for new and existing patients.
OHIP at no cost.
Finding a family doctor in Toronto has become one of the city’s most acute health challenges — over a million Ontarians are without a GP. Tight Clinic King West offers OHIP-covered family medicine with Dr. Noam Raiter MD and Dr. Yuan Yuan Zhang MD, with same-day and next-day availability. Annual physicals, chronic disease management, referrals, mental health assessments, and preventive care — all fully covered under OHIP for Ontario residents.
15 minutes. No downtime.
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme your cells rely on for energy production, DNA repair and aging regulation — and its levels decline naturally with age and stress. An intramuscular NAD+ injection delivers the same cellular benefits as an IV drip in a 15-minute appointment with no line, no chair, no downtime. Single injections from $100. Packages available for sustained longevity support.

Naturopathic medicine, GP & family medicine, and NAD+ injectables at Tight Clinic King West.
Whole-person care.
Real outcomes.
“I’ve been seeing Dr. Rychlik for about a year and the work she’s done on my hormonal health has been genuinely life-changing. She listens, she tests properly, and she doesn’t guess. The fact that I can also see my aesthetics team in the same appointment is an unexpected bonus.”
“Getting a same-day GP appointment in Toronto is essentially impossible now. Tight Clinic King West changed that for me. Dr. Raiter is thorough and actually listens. OHIP-covered and no wait. I’ve referred three people in my building.”
“The NAD+ injections have become a regular part of my wellness routine. The mental clarity and energy improvement after a few weeks of consistent injections was real and noticeable. 15 minutes, no downtime, and the pricing is reasonable for what it delivers.”
