Arginine & Citrulline Powder – Energy, Muscle Pump and Optimal Circulation Through Nitric Oxide Support

Arginine & Citrulline Powder, NOW Foods is a specially formulated dietary supplement designed to support nitric oxide (NO) production in the body and optimize blood circulation, physical endurance and post-exercise recovery. Each serving contains 1.5 g L-arginine (free form) and 1.5 g L-citrulline (free form), two key amino acids that act synergistically in the nitric oxide cycle and the urea cycle. L-arginine is a direct precursor of nitric oxide, a molecule essential for blood vessel dilation and support of blood flow, while L-citrulline is converted into arginine in the body, helping maintain sustained and stable levels.

In the context of an active lifestyle, intense training or periods of fatigue, this combination can support physical performance, muscle oxygenation and recovery, being preferred both by athletes and by people who want more efficient circulation and general support for vitality. Arginine & Citrulline Powder, NOW Foods provides an easy-to-use powder formula, simple to integrate into the daily routine and offering flexibility for combining with other supplements or protein shakes.

Detailed benefits of Arginine & Citrulline Powder, NOW Foods

• Supporting nitric oxide production and vasodilation

Nitric oxide (NO) is an essential molecular messenger for vascular health. It contributes to the relaxation of smooth muscle in the vessel walls, promoting vasodilation and improving circulation. L-arginine is the direct substrate for nitric oxide synthesis, while L-citrulline supports the renewal of arginine stores through its conversion in the body.

By providing 1.5 g L-arginine and 1.5 g L-citrulline per serving, Arginine & Citrulline Powder may help:
✅ Increase nitric oxide production at endothelial level
✅ Promote blood vessel relaxation and support efficient blood flow
✅ Support tissue oxygenation and nutrient delivery, especially during exercise

This nitric oxide support can have a positive impact on how the body copes with physical demands and on overall vitality.

• Support for energy, endurance and exercise performance

During intense training, muscles need increased blood flow to receive oxygen and essential nutrients. By supporting vasodilation and circulation, arginine and citrulline help improve delivery of energy substrates to the muscles.

Arginine & Citrulline Powder, NOW Foods can support:
✅ Increased endurance during exercise – by improving oxygen and nutrient supply
✅ A more intense muscle „pump” – the sensation of volume and muscular congestion during workouts
✅ Reduced feeling of fatigue during sustained exercise

Thus, this supplement is suitable for those who perform weight training, functional training, high-intensity cardio or competitive sports, as well as for active people who want extra energy and a better physical response to effort.

• Support for muscle recovery and reduction of exercise metabolites

L-citrulline also plays an important role in the urea cycle, helping eliminate ammonia resulting from protein metabolism and intense effort. Ammonia accumulated in tissues can contribute to fatigue and reduced performance. By supporting the conversion of ammonia to urea in the liver, citrulline and arginine may promote more efficient recovery.

Benefits at this level include:
✅ Supporting the body’s natural metabolic detoxification processes after exercise
✅ Helping reduce the sensation of muscle „burn” associated with metabolite buildup
✅ Faster recovery between workouts, in the context of a well-structured rest and nutrition plan

Through this dual action – on circulation and nitrogen metabolism – Arginine & Citrulline Powder can help the body recover more easily after demanding training sessions.

• Supporting vascular health and peripheral circulation

A healthy vascular system underpins proper functioning of organs, muscles and peripheral tissues. Nitric oxide generated from arginine helps maintain optimal vascular tone and smooth circulation.

Arginine & Citrulline Powder, NOW Foods provides:
✅ Support for endothelial function – by promoting NO production
✅ Support for peripheral circulation – important for extremities and tissues with high oxygen demand
✅ Complementary intake for active individuals who want to keep their vascular system functioning optimally

By supporting blood vessel health, this supplement can indirectly contribute to overall well-being, better exercise tolerance and a higher level of vitality.

• Support for metabolic balance and anabolic functions

Amino acids play a central role in building and repairing tissues, especially muscle tissue. Although L-arginine and L-citrulline are not strictly essential amino acids, their role in nitrogen metabolism and protein synthesis makes them highly valuable for people with active lifestyles or goals of increasing or maintaining muscle mass.

Arginine & Citrulline Powder may:
✅ Support an anabolic environment by optimizing nutrient flow to muscles
✅ Contribute to efficient utilization of amino acids from diet and other protein supplements
✅ Help maintain a state of muscle repair and regeneration, particularly in intense training programs

This metabolic support is reflected positively in workout performance and in the body’s ability to adapt to physical effort.

• Supporting the immune system and regeneration processes

L-arginine is involved in numerous cellular processes, including optimal functioning of certain immune cells. Also, through its role in nitric oxide synthesis and protein metabolism, it can contribute to tissue regeneration and repair.

Potential benefits include:
✅ Supporting immune response, in the context of a well-nourished and well-rested body
✅ Helping in the repair of micro-lesions in muscles caused by exercise
✅ Providing additional amino acid support useful in periods of intense physical and mental demand

• Synergy between L-arginine and L-citrulline – prolonged and efficient action

One of the strengths of Arginine & Citrulline Powder, NOW Foods is the balanced combination of L-arginine and L-citrulline, 1.5 g each per serving. Arginine provides rapid support for nitric oxide production, while citrulline is gradually converted to arginine, maintaining prolonged levels of this amino acid in circulation.

This synergy translates into:
✅ Longer-lasting effect on NO production compared to arginine alone
✅ Increased efficiency in supporting blood flow throughout exercise
✅ Usefulness both as a pre-workout and as general support for circulation and vitality

Through its powerful combination of L-arginine (1,500 mg) and L-citrulline (1,500 mg), Arginine & Citrulline Powder, NOW Foods offers comprehensive support for nitric oxide production, vascular health, energy, physical performance and muscle recovery, becoming a valuable ally for active individuals and those seeking advanced support for circulation and energy metabolism.
