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.

L-theanine is extracted from tea leaves and included in a gentle, daily dose.

All ingredients are independently tested and manufactured in GMP facilities.

COMPLEMENTARY PRODUCTS

This formula uses Cellg8® liposomal technology, which enhances absorption of B vitamins by protecting them through digestion and improving cellular uptake.

It also contains activated forms of key B vitamins (like methylfolate and methylcobalamin), meaning your body can use them immediately without conversion.

This makes it particularly beneficial for individuals with absorption issues or genetic variations affecting B vitamin metabolism.

“Activated” refers to the biologically active forms of B vitamins that are ready for immediate use in the body.

For example, it includes methylfolate instead of folic acid, and P5P (pyridoxal-5-phosphate) instead of standard B6.

These forms are more effective, especially for individuals with MTHFR gene variants that affect folate metabolism.

While Natroceutics does not currently offer third-party testing on every batch, the Cellg8® active ingredient is tested for heavy metals, contaminants, and potency after manufacturing.

A certificate of analysis (COA) is available upon request, and is signed by the quality assurance manager to ensure full traceability.

No. Natroceutics Vitamin B-Complex Advanced is free from corn, wheat, and rice ingredients.

The only other components are hypromellose (veggie capsule shell), magnesium stearate, microcrystalline cellulose (MCC), silica, and sunflower lecithin—all of which are allergen-friendly and suitable for most dietary needs.

L-theanine is an amino acid found naturally in green tea, included here to complement the energising effects of B vitamins.

It helps promote calm focus without drowsiness, making this B-complex suitable even for those sensitive to overstimulation.

The B-complex is best taken in the morning or early afternoon, preferably with a meal.

This aligns with the body’s natural energy cycles and helps avoid any possible sleep disruption that can occur from late-day B vitamin use.
