B Complex Vitamins for energy and nervous system — Quest
Quest's B Complex 100 is a high-potency supplement with all 8 B vitamins, choline, and inositol, in a 6-hour gradual release formula. It may be beneficial for adults looking to support energy, the nervous system, and psychological balance in their daily lives. One tablet a day, with the main meal, is all that is needed.
The fast pace of daily life can deplete B complex reserves faster than diet can replenish them. The eight B vitamins are involved in energy production from food and in the normal functioning of the nervous system — and insufficient intake can result in fatigue, lack of focus, and reduced mood. Quest's B Complex 100 is a sustained-release formula, with high doses of all B vitamins plus choline and inositol, designed to provide the body with sustained support throughout the day.
✅ Vitamins B1, B2, B3, B6, and pantothenic acid can contribute to the reduction of tiredness and fatigue.
✅ Vitamins B1, B3, B6, B12, and biotin can contribute to the normal functioning of the nervous system.
✅ Vitamins B3, B6, B12, and folic acid can contribute to normal psychological function.
✅ Vitamin B6 can contribute to the regulation of hormonal activity and to the normal metabolism of proteins.
✅ Folic acid can contribute to the normal synthesis of amino acids and to the normal process of cell division.
✅ The gradual release formula can help integrate continuous B vitamin support throughout the day, in a simple and consistent routine.
Quest's B Complex 100 combines all eight B vitamins — thiamine (B1), riboflavin (B2), niacin (B3), vitamin B6, folic acid, vitamin B12, biotin, and pantothenic acid — in high doses, supplemented with choline bitartrate, inositol, and PABA (para-aminobenzoic acid). While B vitamins are essential nutrients with recognized health claims at a European level, choline and inositol are compounds naturally present in the body and in foods, traditionally used in the context of general well-being and vitality.
The gradual release technology is designed to break down and release the tablet's contents over approximately 6 hours, providing more prolonged support throughout the day — particularly useful for demanding routines. The formula does not contain animal-derived substances, gluten, lactose, yeast, artificial preservatives, colorings, or artificial flavorings. Suitable for vegetarians and vegans.
Please note
- Prolonged intake of high doses of vitamin B6 may be associated with moderate tingling or numbness — do not exceed the recommended daily dose.

What is B Complex 100 and what can it be used for?
It is a high-potpotency supplement with all 8 B-group vitamins, with a gradual release over 6 hours. B vitamins are essential for energy production, nervous system function, and daily psychological balance — and can be particularly helpful for those who experience frequent fatigue, difficulty concentrating, or are undergoing periods of increased physical and mental demand.
Who can benefit from this supplement?
Adults with demanding lifestyles, smokers, people who regularly consume alcohol, those following restrictive diets, or those who find it difficult to obtain all B vitamins through their diet. It may also be useful for vegetarians and vegans, who may have a lower dietary intake of vitamin B12.
What is extended release, and what is its advantage?
The gradual release formula was developed to release vitamins over approximately 6 hours after consumption, instead of making them all available at once. This can contribute to more stable support throughout the day, which is particularly relevant for B vitamins, which are water-soluble and not stored by the body in large quantities.
