Malate tubs hold less citrulline than they weigh

Citrulline malate is citrulline mixed with malic acid. The BulkSupplements 2:1 label says 2 g of citrulline in each 3 g scoop, so 6 g takes 3 scoops. We price every malate tub by its citrulline, not its weight. When a label gives no split, we count the most a 2:1 can hold, and the real amount may be lower (why).

We checked each product at its brand’s store, or Vitacost where the store blocked reads. Prices move, and the cheapest tub can change. Check the price on the day you buy.

Many studies used 3 to 6 g of pure L-citrulline a day, and some used up to 10 g (how much to take). Take nitrates for the heart, ED drugs (for erections) like sildenafil, or blood pressure medicine? Ask your doctor first, because blood pressure may drop too far. Pregnant or breastfeeding? WebMD says not to use it.

Capsules cost more: the cheapest we price, BulkSupplements, is $1.53 for 6 g, and 6 g is 16 capsules.
