L-arginine is an amino acid sold as a single-ingredient supplement and as part of pre-workout or sports-nutrition formulas. It is commonly available in capsules, tablets and powders, with substantial differences in the amount provided per serving and the number of daily servings. Compare the total daily amount and all additional ingredients, particularly when combining it with another workout formula. Research provides little support for claims that L-arginine consistently improves strength, athletic performance or recovery. Higher intakes may cause nausea, diarrhoea or other digestive discomfort and may slightly lower blood pressure, so medical advice is appropriate for people with health conditions or regular medication.
