What Is L-Citrulline DL-Malate? Decoding A Long Label Name

Three pieces in one name

At first glance, L-Citrulline DL-Malate looks like a puzzle. The trick is to cut it into parts. There is an L, there is the word citrulline, and there is DL-Malate. Each part answers a different question about the ingredient.

The first two parts tell you which amino acid is listed. The last part tells you what that amino acid is paired with. Once you can separate these, long names on any supplement label stop feeling intimidating.

This guide stays on the naming side of things. It explains what the words mean and how to read them, in general chemistry terms, so that the next time you pick up a bottle you know what you are looking at.

Citrulline: the amino acid

Citrulline is an amino acid. Like arginine, it is closely related to the family of molecules that make up proteins in the foods you eat. Its name comes from the Latin word for watermelon, citrullus, because it was first isolated from that fruit.

Watermelon is the food most often linked with the name, though citrulline also appears in small amounts in other members of the gourd family, such as cucumbers and melons. If you enjoy those foods in summer, you have already met it on your plate.

On a label, the word citrulline names the amino acid itself. Anything attached after it describes the form.

The L at the front is the same L you see in L-Arginine. It names the molecular shape, the left-handed form, which is the form used in food proteins and in most amino acid ingredients.

Reading it this way, L-Citrulline simply means the left-handed shape of the citrulline molecule. It is a precise naming convention and carries no further message about strength, price or quality.

Malate: the partner in the name

The word malate refers to a salt or ester form of malic acid. Malic acid is a naturally occurring organic acid, and it is the compound that gives apples their tart, crisp taste. The name malic even comes from the Latin word for apple, malum.

When an amino acid is paired with malic acid, the combined ingredient is called a malate. So citrulline malate is the amino acid citrulline joined with malic acid in a single, stable ingredient. Manufacturers often prefer paired forms because they can be easier to handle, store and blend into a capsule.

In general chemistry, salts are formed when an acid combines with something else. That is why many supplement ingredients carry names ending in words such as malate, citrate, or hydrochloride.

What DL means in DL-Malate

Here is the part that confuses most readers. Just as L means left-handed, D means right-handed, and DL means a mixture of both mirror-image shapes. A DL-labelled ingredient contains the two shapes together rather than just one.

Malic acid can exist in either shape. When a label says DL-Malate, it is telling you that the malate portion is that mixed version. This is simply a description of the chemical makeup, much like a recipe noting that a sauce is made from two types of tomato.

So the full phrase breaks down like this:

• L: the citrulline portion is the left-handed form
• Citrulline: the amino acid
• DL: the malate portion uses both mirror-image shapes
• Malate: the paired form based on malic acid, the compound found in apples

Where it sits in BloodPril

BloodPril is a daily capsule dietary supplement, and L-Citrulline DL-Malate is one of the four ingredients named by the brand, alongside L-Arginine, L-Arginine HCL and L-Arginine Alpha-Ketoglutarate. All four are amino acid forms.

The Supplement Facts panel on the bottle is where the specific amounts are printed, so that is the reliable place to look. According to the brand, the suggested use is one capsule daily with a glass of water, preferably in the morning before a meal, or as the label directs.

A bottle holds 60 capsules, and packs of 2, 3 and 6 bottles give 60, 90 and 180 day supplies. If you like to plan ahead, that is simply a matter of counting how many mornings you want covered.

A few vocabulary shortcuts

Ingredient lists reuse the same small set of word parts, so a short glossary goes a long way. Keep these in mind and you will decode names far faster than you expect.

The word part acid usually points to an organic acid such as malic, citric or ascorbic. An ending of ate, as in malate or citrate, usually means that acid has been paired with another substance. An ending of ine, as in arginine or citrulline, is very common for amino acids.

Brand claims also appear on a label, and it helps to read them as statements the company is making. According to the brand, BloodPril is made in the USA in a GMP-certified, FDA-registered facility. That sentence describes the place and process of manufacturing, and it is separate from the ingredient names.

If you ever want to compare two products, line up the ingredient names side by side. Matching names mean the same ingredient, while different endings mean a different paired form. That small habit makes comparison shopping calmer and more accurate, and it costs you only a minute.

Reading any long name with ease

The method you just practised works almost everywhere. Split the name at the hyphens and spaces. Identify the main word, usually the amino acid or vitamin. Spot any shape letters at the front. Then look at the ending to see what the ingredient is paired with.

Try it on the next label you pick up. You will find that most names are less mysterious than they first appear, and that the ending words tend to repeat from one product to another.

Pair that label reading with simple routines such as a glass of water in the morning, a protein-rich breakfast and a short walk, and you have a relaxed, informed approach to daily wellness.
