Nutrient Store Sale

The standard behind everything we carry

For over 30 years, every product that has come through the doors of the Riordan Clinic Nutrient Store has cleared the same bar: would our providers recommend it to their own patients?

Most products don’t make it. The ones that do are here because of their ingredients, their sourcing, the integrity of their manufacturing, and whether the dose is clinically meaningful. Form matters. Dose matters. The supplement that almost works is the one you take every day without knowing it isn’t working.

The products that clear our highest bar, we carry under our own name.

The Riordan Clinic line

These aren’t private-labeled generics. Every formula in our store-brand line was developed by our clinical team — built around what our providers kept wishing existed, at the right dose, in the right form, for the patients sitting across from them. Thirty-plus formulas. Each one with a reason.

C-1000 (Vitamin C) — 180 or 250 Capsules

Foundational immune and connective tissue support. Vitamin C participates in more biological processes than most people realize — neurotransmitter synthesis, collagen production, iron absorption, antioxidant defense. We’ve carried this one since the beginning because the need never changes.

CoQ10 Ubiquinol — 60 Softgels

The form your body can actually use. Ubiquinol is the active, reduced form of CoQ10 — significantly better absorbed, especially as we age. Critical for cellular energy production and cardiovascular health, and a staple for patients on statin therapy.

Chelated Magnesium Plus — 120 Capsules

Magnesium is involved in over 300 enzymatic reactions. Most people are deficient and don’t know it. The chelated form means better absorption and fewer of the digestive side effects that cause people to give up on it.

Adrenal Adapt — 60 Capsules

Designed to support healthy cortisol levels and strengthen the body’s resistance to stress. Not a stimulant. Not a bandage. A formula built for sustained resilience, not a short-term lift.

MitoForm — 60 or 120 Capsules

Mitochondrial support for energy at the cellular level. For patients who feel like their energy never quite recovered — from illness, from treatment, from the accumulation of years — this is often where we start.

Melatonin 20mg — 100 Capsules

At this dose, melatonin goes well beyond sleep. It supports immune function, antioxidant activity, and healthy angiogenesis. A protocol staple for many of our integrative oncology patients.

Why it matters where you buy

When you order through our store, you get exactly what your provider recommended — the same formulation, the same dose, every time. That consistency is the whole point. Your body responds to what you take regularly, at the dose chosen for you. The gaps are where progress quietly resets.

Purchasing directly from us also means you’re supporting the clinic, the research, and the education programs behind this work. The Riordan Clinic is a 501(c)(3) nonprofit. What you spend here goes back into the mission.
