The Problem
You've Read Enough.
You're Still Confused.
You've seen the articles. The influencers. The endless debates about which form is best, what dose to take, whether it even works.
Every source says something different. And you're still not sure if the vitamin C you've been taking is actually doing anything.
What if the problem was never which brand you chose — but how much of it your body could actually use?
The Missing Piece
Standard Vitamin C May Not Fully Reach Your Cells
Your body can only absorb so much vitamin C through normal digestion. Studies suggest you may absorb as little as 20% of a standard oral dose. The rest stays in your colon, pulls in water, and can contribute to the stomach discomfort some people experience with high-dose
vitamin C.1
This is why higher doses of regular vitamin C cause problems. It's not that vitamin C is bad for you — it's that your gut can't handle what it can't absorb.
Researchers have explored different delivery methods to improve vitamin C absorption.
Vitamin C absorption can vary
depending on dose and form.

Why It Matters
When Vitamin C Gets There, It Does a Lot
Supports Immune FunctionHealthy individuals have high concentrations of vitamin C in their immune cells. It's one of the most well-studied nutrients for immune support.*2
Builds CollagenYour body needs vitamin C to make collagen — the structural protein in your skin, bones, blood vessels, tendons,
and ligaments.*2
Supports the Body's Natural Antioxidant DefensesAs the "grandfather" of antioxidants, vitamin C donates electrons to neutralize oxidative stress. It even helps regenerate other antioxidants like vitamin E.*2
Supports Heart HealthResearch suggests vitamin C may support healthy blood vessel function and endothelial health.*3
The Human Problem
Your Body Can't Make Vitamin C
Most mammals produce their own vitamin C. You still have the gene for it — it just doesn't work. Guinea pigs, primates, and humans are the exceptions. We have to get it from food or supplements every single day.
Only 1 in 10 adults eat enough fruits and vegetables to meet their vitamin C needs through diet alone. If that's you, supplementing makes sense.
The question isn't whether to take vitamin C. It's whether what you're taking is getting where it needs to go.
The Solution
Liposomal Technology Changes the Math
Liposomal delivery wraps vitamin C in phospholipids — the same building blocks that make up your cell membranes. These tiny spheres, called liposomes, can form in your stomach and carry the vitamin C through your
gut lining.
The result? Liposomal delivery is designed to help vitamin C pass through the digestive process. And because less stays behind in your colon, many users find liposomal vitamin C easier to tolerate.4
We tested ours in the lab using dynamic light scattering. Laboratory analysis observed liposome-sized particle formation under controlled test conditions.5
"We wanted a vitamin C formulation designed to deliver. One you don't have to think about."
Dr. Joseph Mercola
How It Works
Three Steps. That's It.
1
Phospholipids Wrap the Vitamin CThe same fats found in your cell membranes surround and protect each vitamin C molecule.
2
Liposomes Form in Your StomachWhen you take the capsule, tiny protective spheres can form in stomach fluids, carrying the vitamin C through your gut lining.
3
More May Reach Your BloodstreamEncapsulation may help protect vitamin C during digestion — with less chance of the stomach upset associated with regular vitamin C.4

FAQ
Quick Answers
Two capsules daily with water. That's it. Can be taken with or without food.
Liposomal technology wraps vitamin C in phospholipids, which may help more of it reach your bloodstream. It's also gentler on your stomach than standard vitamin C at higher doses.4
That's one of the main benefits. Because liposomal vitamin C is designed to be absorbed rather than left behind in your colon, it's generally much easier on the stomach than regular vitamin C.4
Many people prefer to avoid soy. Sunflower lecithin provides the same phospholipids needed to form liposomes, without any soy.
