Prom-In Liposomal Vitamin C 120 cps

Premium Liposomal Complex

PROM-IN® Liposomal Vitamin C is a premium vitamin C in the CELLg8® liposomal complex, supplemented with quercetin from Sophora japonica extract.4.

Thanks to its unique technology, it can effectively increase serum vitamin C levels in specific situations ^2,3,4. Are you under stress, fighting an infection, recovering from an injury, or going through a period of extreme physical or mental strain? These are precisely the situations when it’s the right time to supplement with vitamin C in an advanced technological form ^1,2,3.

Vitamin C has absorption limits that depend on transport mechanisms in the intestine, which have limited capacity. Therefore, as the dose of standard vitamin C increases, the percentage absorbed decreases, and a larger portion is excreted from the body 1. This is where the advantage of the CELLg8® liposomal complex comes in. It^pushes these limits^2,3,4.

Each capsule provides 500 mg of vitamin C and 50 mg of quercetin. A full daily dose of 2 capsules contains 1,000 mg of vitamin C and 100 mg of quercetin, creating a synergistic combination ^4,5,6.

CELLg8®

We use the proprietary CELLg8® complex, which contains 85% vitamin C liposomes; here, vitamin C is incorporated into a lipid matrix ⁴. This proprietary matrix mimics phospholipid structures and creates an environment that protects vitamin C as it passes through the digestive tract, ensuring unparalleled bioavailability in the blood ^2,3,4. With conventional vitamin C, absorption is limited by the capacity of intestinal transporters; therefore, absorption decreases as the dose increases ¹. Clinical data on liposomal forms show the potential to achieve high plasma concentrations of vitamin C, and recent studies indicate even higher concentrations of vitamin C in leukocytes—that is, immune system cells— ^2,3. For CELLg8®, the manufacturer also reports its own data showing approximately 2.5 times higher vitamin C levels compared to competing products ⁴.

Quercetin and Liposomal Vitamin C

Quercetin, in synergy with vitamin C, is also of interest because it has been studied in recent years in relation to the immune response, inflammatory signaling, oxidative stress, and the body’s response to increased stress 5, 6. It fits logically into the formulation as a flavonoid synergist that expands the product’s concept toward cellular protection during periods of increased^{stress 5,6}.

We combine a high dose of vitamin C in the CELLg8® liposomal complex with quercetin, creating a product in which vitamin C helps protect cells from oxidative stress—which is particularly important during^times of^{stress¹⁻²,3,4,5,6,7}.

Directions for use:

1 capsule daily

Daily vitamin C boost.

A basic increase in intake during regular training or physical exertion, to support normal immune system function, protect cells from oxidative stress, and support normal collagen production ⁷.

2 capsules daily

Full daily dose of the product.

Recommended when aiming for a noticeable increase in serum vitamin C levels ^2,3,4. Typically during periods of increased physical or mental stress, more intense training, travel, seasonal transitions, or when you want to significantly support collagen production for blood vessels, skin, cartilage, gums, as well as bones and teeth ⁷.

Up to 4 capsules daily

For short-term use during

periods

of increased need.

This dosage is suitable for temporary use, such as during periods of significant physical or mental stress. During an extremely demanding training block or in protocols focused on more intensive support for the body and tissues ^1,7.

It is precisely at these high doses that the benefits of the liposomal form are fully realized.

Practical Tips:

• Take the basic dose in the morning or mid-morning.
• If you have a sensitive stomach, take it with a meal.
• For higher doses, spread the intake throughout the day, for example, 2 capsules in the morning and 2 capsules in the afternoon.
