Vitamin B complex is a group of B vitamins that play a role in your body's functions, including cardiovascular and cell health. Adequate amounts of B vitamins are essential for optimal neurological function such as memory, concentration, learning, reasoning, thinking, planning, language, attention, alertness, and mood. B Vitamins are also important for protein metabolism and increasing the growth of red blood cells. In turn, this function can help transport oxygen to the body tissue, increasing energy. Nevancia Vitamin B Complex is formulated by experts with all the B vitamins (8 different essential B vitamins), making this formula one of the best Vitamin B supplements on the market today. These include B-1 (thiamine), B-2 (riboflavin), B-3 (niacin), B-5 (pantothenic acid), B-6 (pyridoxine), B-7 (biotin), B-9 (folic acid) and B-12 (cobalamin).B-group vitamins have a limited capacity for storage within the body, and since they are not produced naturally in our body, they must be consumed through food or supplements. Unfortunately, many people do not consume adequate amounts of the B vitamins from foods because of various lifestyle factors, including poor diet. Our Vitamin B Complex supplement helps to bridge gaps in our nutrition which is important especially in today's day and age of fast food that does not offer a balanced diet for most of us.
