Mixed reception with practitioners skeptical of arginine as a standalone NO solution, while some note blood flow benefits and comparable value to competitors.
NOW Sports Arginine & Citrulline combines 500mg of L-Arginine with 250mg of L-Citrulline per capsule — two amino acids that work together to support nitric oxide production and healthy circulation. This pairing is popular among active individuals looking to support exercise performance and vascular function.
Why It's Worth Considering: Combining these two precursors in a single capsule takes advantage of their complementary pathways — L-Citrulline recycles back into L-Arginine in the kidneys, potentially extending availability compared to either amino acid alone.
Store in a cool, dry place away from direct sunlight. Most supplements are stable at room temperature (59-77°F). Keep the bottle sealed between uses. Check the label for any specific storage requirements — some probiotics and oils require refrigeration.
Most supplements can be taken together safely. However, some minerals compete for absorption (zinc and iron, calcium and magnesium) and should be taken at different times of day. If you're taking prescription medications, consult your healthcare provider about potential interactions.
Most supplements benefit from consistent daily use over 2-3 months to achieve full effect. Some (like vitamins and minerals) can be taken indefinitely as part of a daily routine. Others (like specific herbs) may benefit from cycling. Follow the product's recommended protocol or consult a practitioner.
Fat-soluble supplements (vitamins A, D, E, K, omega-3, CoQ10) should be taken with a meal containing fat. Water-soluble supplements (B vitamins, vitamin C) can be taken anytime. Minerals are generally best absorbed with food. Probiotics should be taken with or just before a meal. Check the product label for specific timing recommendations.
Track your specific health goals — energy levels, sleep quality, joint comfort, digestion, mood, etc. Most supplements take 2-8 weeks for noticeable effects. For objective measurement, baseline lab tests before starting (and repeat at 3 months) provide definitive evidence. The Gabriel Score incorporates clinical evidence for expected outcomes.
