Neutral read

“Customers have reported mixed experiences with the NOW Foods L-Arginine supplement. Many users praised its high quality, easy-to-swallow capsules, and effective packaging. Several noted improvements in energy levels, reduced fatigue, better sleep, and enhanced physical performance during workouts. Some also mentioned benefits for heart health and blood pressure management. However, a few customers did not notice significant effects within a short period of use and found the pill size too large to swallow easily. Overall, the supplement is well-regarded for its natural ingredients and multifaceted health benefits.”
