Prom-In Serious PRE Natural 705 g lemon mint

Serious PRE 2.0 Natural is based on the same functional concept as the basic version, but is flavored exclusively with natural flavors and stevia—without synthetic dyes or sweeteners.

It retains the full effectiveness of the ergogenic axis of citrulline–beta-alanine–creatine HCl and the neurocomplex of tyrosine–choline–theanine, while eliminating substances that could unnecessarily burden the detoxification or nervous systems.The goal is maximum purity of ingredients and long-term tolerability without compromising physiological effectiveness. The flavor is naturally milder—for those who want to avoid any additives.

PROM-IN® Serious Natural PRE 2.0 and Performance Support

Performance during physical exertion is limited by blood flow, the ability to buffer acidic metabolites, and rapid energy recovery. PROM-IN® Serious PRE 2.0 therefore contains a combination of three substances whose effectiveness is well documented.

• L-citrulline malate (7,000 mg) —citrulline is a precursor to arginine and thus to nitric oxide (NO), which supports vasodilation and the delivery of nutrients to the muscles. The malate form offers an added benefit: malic acid participates in the Krebs cycle and may support energy production. Studies show that doses above 6 g of citrulline malate improve endurance and delay the onset of fatigue (Bailey et al., 2015; Pérez-Guisado et al., 2010).
• Beta-alanine (3000 mg) – a well-known precursor to carnosine, which acts as a buffer for hydrogen ions. When taken regularly, it increases endurance during exercise lasting 1–4 minutes—the range where the greatest adaptive stimuli occur. A meta-analysis (Saunders et al., 2017) confirms a significant effect on interval performance.
• Creatine HCl (3,000 mg) —a highly soluble form of creatine that provides a similar effect to 5 g of monohydrate but with a lower risk of gastrointestinal discomfort. EFSA confirms that a daily intake of 3 g of creatine enhances physical performance during repeated short-term, high-intensity exercise.

Synergy: Citrulline improves blood flow, beta-alanine delays acidification, and creatine replenishes ATP stores. Together, they form the performance triangle: more reps, higher intensity, longer duration.

PROM-IN® Serious PRE 2.0 - natural and support during exercise

Training is not a time for recovery, but a period of maximum performance. That is why PROM-IN® Serious PRE 2.0 - natural contains ingredients that can be utilized directly during physical activity.

• BCAAs (L-leucine 3000 mg, L-isoleucine 1500 mg, L-valine 1500 mg) – branched-chain amino acids are metabolized directly in the muscles, providing an immediately available source of energy. Leucine also activates the mTOR signaling pathway, which is key for subsequent adaptation to exercise (Shimomura et al., 2006).
• Taurine (1,000 mg) – an osmolyt and antioxidant that modulates calcium transport and supports stable muscle fiber contraction. Its protective role during intense exercise has been documented in numerous studies (Ghandforoush-Sattari et al., 2010).

Synergy: BCAAs provide immediate fuel, while taurine stabilizes the cellular environment. The result is longer-lasting and more stable performance, where energy levels do not drop suddenly but remain under control.

PROM-IN® Serious PRE 2.0 - natural and concentration support

The nervous system is a key factor in performance. PROM-IN® Serious PRE 2.0 - natural therefore combines ingredients that support cognitive stability and focus without excessive stimulation.

• L-tyrosine (1,000 mg) – a precursor to catecholamines (dopamine, norepinephrine). Studies show that tyrosine supplementation can support cognitive performance during stress and fatigue (Jongkees et al., 2015).
• CDP-choline (250 mg) —a source of choline for the synthesis of acetylcholine, a neurotransmitter critical for cognitive performance and attention.
• L-theanine (250 mg) —an amino acid found in tea. Research confirms that it contributes to a state of “calm alertness”—improving concentration while simultaneously dampening excessive neural activation (Unno et al., 2018).
• Acetyl-L-carnitine (500 mg) —a carnitine derivative that supports mitochondrial metabolism and contributes to long-term mental performance and resilience (Montgomery et al., 2003).

Synergy: Tyrosine and CDP-choline support dopamine and acetylcholine neurotransmission, theanine stabilizes the nervous system, and ALCAR provides the energy foundation for neurons. Together, they create a state of focused energy without overstimulation.

PROM-IN® Serious PRE 2.0 – Natural Ingredients and Micronutrients

Every detail matters. That’s why PROM-IN® Serious PRE 2.0 is supplemented with micronutrients and bioactive ingredients in doses that are both effective and safe.

• Niacin (30 mg, 188% RDA) – a precursor to the coenzymes NAD+ and NADP+, which are essential for hundreds of enzymatic reactions involved in energy metabolism. The flush effect is related to vasodilation and is a natural consequence of its action. In the context of a pre-workout supplement, niacin supports efficient energy flow and the smooth utilization of substrates during exercise.
• Vitamin B6 ( pyridoxal-5’-phosphate, 1.1 mg = 78% RDA) – the active form of vitamin B6, which participates in amino acid metabolism and the production of neurotransmitters (dopamine, serotonin, GABA). It also supports gluconeogenesis—the production of glucose from non-carbohydrate sources—which is essential during prolonged physical exertion. Unlike high doses, a safe concentration suitable for long-term use has been selected here.
• BioPerine® (1 mg) – black pepper extract standardized to piperine. In a targeted low dose, it increases the bioavailability of selected ingredients (particularly CDP-choline and ALCAR) without increasing the risk of interactions with other supplements.

Synergy: Niacin provides energy through the NAD+/NADH cycle, B6 supports neurotransmitter balance and amino acid metabolism, and BioPerine® enhances the absorption of key ingredients. Together, they create a metabolic foundation that allows the other ingredients to fully exert their effects.

PROM-IN® Serious PRE 2.0 - natural is a pre-workout supplement based on scientific research, functional dosages, and a commitment to long-term health. It does not promise the illusion of immediate stimulation, but supports performance and concentration in accordance with physiology and the principles of adaptation
