Hey-

Despite being one of the most familiar supplements in America, recent coverage by Fox News has put high-dose vitamin C delivery back in the conversation, raising an important question:

Does the number of milligrams tell you how much your body actually receives?

Not necessarily.

Before vitamin C can support antioxidant defense, collagen formation, or immune function, it first has to become available to the tissues and cells that depend on it.

A 2024 article published in the National Library of Medicine found:
“Liposomal formulation of vitamin C increases absorption into plasma and leukocytes.”

In the study, liposomal vitamin C produced higher peak plasma concentrations, greater total plasma exposure over 24 hours, and increased uptake into leukocytes compared with standard vitamin C.

Leukocytes are immune cells, and vitamin C supports several functions involved in immune defense while also helping protect cells from oxidative stress.

So the biological value of vitamin C depends on more than how much you swallow, but on keeping enough available for the cells and tissues that use it.

That’s why Zelenko Labs formulated Liposomal-C with 1,000 MG (MILLIGRAMS) of vitamin C surrounded by phospholipid-based liposomes designed to protect the nutrient through digestion and enhance its delivery.

It also supports several daily biological functions, including:

• Antioxidant defense
• Healthy immune function
• Collagen formation
• Overall cellular and tissue health

The serving on the label tells you what is in the capsule. The delivery system helps determine how much of that dose your body can actually use.
