B vitamins are a group of water-soluble nutrients involved in a wide range of biological functions, including the way the body produces energy and supports nervous system activity.

Many of these vitamins are sensitive to heat and processing, and their active forms are not always well absorbed through diet alone.

Vitamin B-Complex Advanced includes all eight essential B vitamins in their bioavailable forms, such as methylated B12 and folate. It also includes L-theanine, a naturally occurring amino acid found in tea leaves, which is often included in supplement routines that focus on calm alertness.

This formula is delivered in a clean, vegan capsule with no unnecessary ingredients or plastic packaging.

Adults and children over 12 years:

Take 1 capsule per day or as recommended by your
healthcare professional.

L-theanine, Pantothenic acid, Thiamine, Pyridoxal-5-phosphate, Niacin, Niacinamide, Riboflavin-5-phosphate, Biotin, Methyltetrahydrofolate, Adenosylcobalamin, Methylcobalamin, phospholipid bilayer (sunflower lecithin), capsule shell (hydroxypropyl methylcellulose), microcrystalline cellulose, magnesium stearate.

Store in a cool, dry place below 25°C. Protect from light and moisture.

B vitamins are provided in their activated or coenzyme forms to support better uptake.
