RHO Liposomal Technology

How It Works

step 1

Encapsulation

Nutrients are enclosed within liposomes—tiny, lipid-based spheres designed to protect active ingredients.

step 2

Delivery

Liposomes transport nutrients through the digestive system, shielding them from breakdown.

step 3

Designed For High Absorption

Traditional supplements break down in digestion. Our phosphatidylcholine-based liposomes act as protective carriers, ensuring nutrients reach your cells intact and potent.

Must buy!

I’ve been using Rho Quercetin for the past few weeks and have noticed a clear improvement in my overall wellness, particularly in my seasonal allergy symptoms and energy levels. The formulation is clean and easy to digest, and I really appreciate that it combines quercetin with other supportive ingredients for better absorption and effectiveness.

What sets Rho apart from other supplements I’ve tried is the noticeable purity—no fillers, no strange aftertaste, and no side effects. I’ve had fewer allergy flare-ups and feel more resilient day to day. It’s also become a part of my regular immune support stack, especially during high-stress or travel-heavy weeks.

Highly recommend for anyone looking to reduce inflammation, support immunity, or manage histamine response naturally. Will definitely be reordering!

Allergy relief

I have seen a huge difference in my allergy symptoms since I to started taking this product. It's definitely a keeper and I'll be adding it to my regimen.

Clutch

Quercetin is a multimodal powerhouse ingredient. Having access to a highly-available liposomal quercitin is clutch. Being in a palatable liquid form makes it easy to stay consistent and means less pills to swallow.

It is no wonder why biohackers have this in their supplement stacks. Quercetin is associated with antioxidant & anti-inflammatory effects (which may play a role in protecting against neurodegenerative disease), immune support, cardiovascular benefits (like improved endothelial function), antihistamine effects, exercise recovery, and longevity (via activating AMPK & sirtuins, inhibiting cellular senescence, and supporting mitochondrial health).

Liposomal delivery is a technique used to enhance the absorption and bioavailability of certain nutrients or compounds.

This method improves the delivery of nutrients to target cells and tissues, maximizing their therapeutic effects.
