Alpha Lipoic Acid and L-Leucine: The Two Partners in a Benfotiamine 3-in-1

By the Zespo team · Updated 26 October 2026

Some benfotiamine products combine three ingredients in one capsule. Benfotiamine is a fat-soluble form of vitamin B1. Here are the other two.

Alpha lipoic acid (ALA)

Alpha lipoic acid is a sulphur-containing compound that the body makes in small amounts. It is present in foods such as spinach, broccoli, tomatoes and organ meats. Supplements usually list it in milligrams per serving.

L-leucine

L-leucine is an essential amino acid, meaning the body cannot make it and it must come from food. It is one of the three branched-chain amino acids (BCAAs), found in dairy, eggs, soy, pulses and meat.

What to check before you buy

• The amount of each ingredient per serving, not just per capsule
• How many capsules make one serving and how many servings are in the pack
• Whether any ingredient sits inside an undisclosed "proprietary blend"
• An FSSAI licence number and the veg/non-veg mark on the pack
