Liposomal Vitamin C 120 capsules

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.

This specific combination is an ideal choice for effectively supplementing vitamin C during periods of increased physical and mental demands, intense training, or stress.

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, as 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 ^matrix⁴. This proprietary matrix mimics phospholipid structures and creates an environment that protects vitamin C as it passes through the digestive tract, ensuring unmatched bioavailability in the blood ^2,3,4. With conventional vitamin C, absorption is limited by the capacity of intestinal transporters; therefore, bioavailability decreases as the dose increases ¹. Clinical data on liposomal forms indicate the potential to achieve high plasma concentrations of vitamin C, and recent studies also show higher concentrations of vitamin C in leukocytes—that is, immune system cells ^—²³. For CELLg8®, the manufacturer also reports its own data showing approximately 2.5 times higher vitamin C levels compared to competitors 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, resulting in a product in which vitamin C helps protect cells from oxidative stress—which is particularly important during^periods of^{stress¹⁻²,3,4,5,6,7}.

Directions:

1 capsule daily

A 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 recommended for temporary use, such as during periods of significant physical 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 early afternoon.
• If you have a sensitive stomach, take it with a meal.
• For higher doses, spread your intake throughout the day—for example, 2 capsules in the morning and 2 capsules in the afternoon.

Nitrox Pump Caffeine Free 22.5 g

Nitrox Pump Caffeine-Free is a pre-workout supplement for athletes who can generate intensity in a short time through sheer willpower and mental focus alone—they don’t need caffeine or any stimulants. It is based on the same physiological concept as Caffeine+ and creates an environment that remains stable even in the “storm” of their workout. Nitrox Pump Caffeine-Free relies on the synergy of citrulline, A-AKG, beta-alanine, and creatine HCl, which support blood flow, contraction mechanics, and localized muscle work. The Neurofocus complex (tyrosine, theanine, CDP-choline) supports focus and controlled performance—this time with a smooth, stimulant-free onset. Nitrox Pump Caffeine-Free is designed for athletes who don’t need a kick. They need space. Space where their own intensity can be fully expressed—precisely, cleanly, and with discipline. For those who train hard, fast, and to the fullest—and want a product as reliable and consistent as they are. Nitrox Pump Caffeine+ is a pre-workout for athletes who can generate brutal intensity in a short amount of time and need to ensure their body can withstand that onslaught. NITROX PUMP CAFFEINE+ is built on the synergy of citrulline, A-AKG, beta-alanine, and creatine HCl, which create the conditions for uncompromisingly intense sets. The Neurofocus complex (tyrosine, theanine, CDP-choline), supplemented with caffeine and synephrine, supports focus and controlled intensity—without overstimulation. Nitrox Pump Caffeine+ is designed for those who don’t need motivation, but a tool that allows them to fire on command and hit the mark precisely. For athletes who train hard, fast, and to the fullest—and want a product as reliable as they are.

Nitrox Pump Caffeine-Free — a product for short, intense workouts

Nitrox Pump Caffeine-Free is a pre-workout for athletes who train briefly, intensely, and precisely—and want to perform at their peak in a limited amount of time without caffeine or stimulants. It doesn’t rely on a quick “kick.” It’s based on the physiology of intensity: blood flow, stable contraction, a clean onset, and the ability to explode without losing control. The foundation consists of high doses of citrulline, beta-alanine, and A-AKG, which create the conditions for hard, short sets. Taurine maintains the environment inside the muscle cell so that contractions don’t falter mid-movement.

The Neurofocus complex (tyrosine, theanine, CDP-choline) promotes a state where your mind is calm yet precisely focused. Caffeine-free. Synephrine-free. Stimulant-free. Just a clean, steady onset that sustains your own intensity and focus. Nitrox Pump Caffeine-Free is for athletes who don’t need a kickstart. They have their own motivation and mental mindset. All they need is an environment that provides physiological support for their strong mental mindset.

Performance & Pump — a synergy that sustains intensity

In a short, intense workout, it’s not a single ingredient that makes the difference. What matters is the environment you can create within your muscles. Nitrox Pump Caffeine+ is built on a combination used in sports nutrition precisely when you need to “explode” and maintain intensity throughout an entire set.

Citrulline Malate (6.5 g) Citrulline is one of the most widely used substances for supporting blood flow and localized muscle work at higher intensities. The dose in Nitrox is designed for heavy training loads, not just a token pump.

A-AKG (3 g) A-AKG is a combination of arginine and alpha-ketoglutarate, used specifically to target the pump, optimal blood flow, and localized muscle exertion. It works well on its own—but it has the strongest effect when combined with citrulline, since each works through a different mechanism.

Citrulline + A-AKG Synergy Both amino acid forms are used in sports nutrition to support the conditions required for intense training: improved blood flow, more stable muscle performance, and the ability to maintain high-quality contractions even at a demanding pace. Together, they create an environment that athletes describe as a stronger pump and better power output during sets—without stimulants.

Beta-alanine (3 g) Beta-alanine is a common and long-established solution for high-intensity workouts. The dose is calibrated to support short, intense bursts of effort—not extreme paresthesia.

Creatine HCl (2 g) Creatine is one of the most thoroughly researched substances in sports nutrition. The hydrochloride form offers good solubility and precise dosing—ideal for a pre-workout.

Neurofocus — Clear Focus, Calm Mind

Intense training isn’t just about muscles. It’s about how quickly you can shift into performance mode, maintain precision, and not lose control even when pushing your limits. Nitrox Pump Caffeine-Free is built on a combination of ingredients used in sports nutrition where clear focus, technique, and a steady pace are needed—no caffeine, no synephrine, and no stimulants. The onset is smooth, controlled, and steady.

L-tyrosine — An amino acid commonly used to support focus during physical exertion. It helps keep your mind clear and focused on performance.

L-theanine — Promotes a calm mental state without drowsiness. When combined with tyrosine, it creates a balance between relaxation and precise focus.

CDP-choline — A compound used in nootropic blends where coordination and precision of movement matter—even at a fast pace.

The result? Clear focus. A steady mind. A smooth onset that maintains intensity—without stimulants.

Who Is Nitrox Pump Caffeine-Free For?

Nitrox Pump Caffeine-Free is a pre-workout supplement for athletes who can train hard—not because something gives them a boost, but because that’s just who they are. For people who can stay calm and sharp at the same time. Who don’t need an external boost to deliver the kind of intensity that hurts—yet comes naturally to them. It’s for athletes who possess a discipline that no one sees, but everyone feels. And they want a product that doesn’t disrupt, rush, or overstimulate their performance—but simply creates a space where mind and body meet at the right moment, without caffeine or stimulants.

Nitrox Pump Caffeine-Free is built on a combination of ingredients that do one thing: create the physiological conditions for hard, precise, and controlled performance. Nothing more. Nothing extra. Just an environment that delivers: blood flow where you need it, a contraction that doesn’t falter mid-set, and focus that stays sharp even without stimulants. Nitrox Pump Caffeine-Free was created for athletes who don’t need to seek motivation—they have it in their blood. All they need is a space where they can instantly switch into performance mode. And they know that their intensity deserves a tool that’s just as reliable and disciplined as they are.
