What it is
Vitamin B is often called Vitamin B complex, as it comprises eight different vitamins of B group (plus four more unclassified vitamins). These vitamins correspond to one group as they can be found in the same food and considered earlier to be just one vitamin. They also often function together for the benefits of metabolic processes in the body, nervous system, skin, nervous system, etc.
Vitamin B supplements can include all the B complex or one / several B Vitamins. Sometimes supplements contain some other Vitamins, such as C. It is very important for our body to get all the vitamins in the B group, as each Vitamin contain unique properties that could not be replaced.
Vitamin B complex contains:
B-1 Vitamin, also called thiamin; this Vitamin was first one to be discovered
B-2 Vitamin, or riboflavin;
B-3 Vitamin, called niacin; that includes nicotinic acid and nicotinamide
B-5 Vitamin, or pantothenic acid;
B-6 Vitamin, or pyridoxine;
B-7 Vitamin, also known as vitamin H, or biotin (not always present in Vitamin B complex supplements)
B-9 Vitamin, also called folic acid;
B-12 Vitamin, or cobalamin
Sometimes other unclassified vitamins of the B group can be found in B vitamin complex supplements: amygdalin (B-17), adenine (B-4), adenylic (B-8) and pangamic (B-15) acids.
What it does in the body
All the vitamins in group B play its important role in the functioning of the body, and they actually function together for the benefit of the whole body, helping one another support our good health. In complex they not only supply your body with energy, but improve your metabolic rate and function of immune and nervous systems, help to keep skin and muscle health and promote cell division and growth. Vitamin B complex also reduces the risk of different diseases.
Thiamin is responsible for good heart and brain function, and metabolism of carbohydrates. It is very good for your nervous system. Riboflavin is an important body antioxidant that plays an important role in metabolic and oxidation processes. Niacin also metabolizes fats and carbohydrates and due to its enzyme systems affects all the body tissues. B-5 is very important for the digestive system and muscle functioning, as well as in production of some hormones and fatty acids. Healthy-skin vitamin B-6 helps in metabolism of fatty and amino acids and production of red blood cells. This vitamin is also vital for functioning of different enzymes in the body. Folic acid, very often called pregnancy vitamin (as it is always proscribed when pregnant and when you plan to get pregnant) plays an essential role in the cells creation in the blood-forming organs and healthy development of your baby during pregnancy. It also helps in cell division processes. Folic acid in combination with B-12 helps in producing red blood cells.
As for other vitamins, that are included in group B, they are synthesized by your own body and their deficiencies are not known to be associated with any disease.
Sources of Vitamin B
Some of the vitamins of B group are synthesized by the body; most of them must be consumed with the food (or food supplements) every day, as these vitamins can be stored in your body and excess is excreted in your urine.
The best source of thiamin is liver and yeasts, other products that contain B1 vitamin are pork, whole-grain cereals and whole-wheat flour products, navy beans, rye and kidney beans. Riboflavin can be found in meats (especially lean meat), cheese, eggs, nuts, milk; in less quantity – in whole grains, fish, legumes, green vegetables. Niacin is present in green vegetables, tomatoes, beans and peas, in the cereal husk; also in milk, meat, fish, liver and yeast.

Thiamin deficiency causes weakness, nausea, fatigue, vomiting, muscle weakness and also depression, irritability and memory loss. Serious deficiency causes beriberi, a nervous system ailment
Riboflavin deficiency is associated with some genetic defects and other different ailments, such as ariboflavinosis
Nicotinic acid deficiency causes pellagra, a disease that is characterized by nervous or mental disorders, gastrointestinal disturbances and erythema
B-5 vitamin deficiency causes pantothenic acid deficiency that is associated with marasmus and other nutritional deficiencies; acne and paresthesia
Pyridoxine deficiency causes different metabolic problems (B-6-responsive anemia, B-6-dependent convulsions, etc.), as well as depression, dermatitis, water retention and hypertension
Biotin deficiency is associated with muscle pains, skin and membrane inflammation and depression
Folic acid deficiency increases the risk of neural tube defects in newborns and the risk for heart attacks in grown-up population
B-12 deficiency causes pernicious anemia, a serious disease resulting in large, immature red blood cells production, memory loss, elevated homocisteine, and in some cases mania and psychosis
What happens in case of Vitamin B overdose?
Problems with exceeding the dosage of vitamin B are generally not the issue at all; as the excess usually passes safely out of the body with your urine, as they are water soluble. But in case of supplements it is better to follow the recommended dosage, as it may cause some problem (for example too much niacin can cause itching, flushing, gout, and even liver damage; and high doses of folic acids when given to people with vitamin B 12 deficiencies may cause nerve damage). Good health to you.
Shaklee is an amazing company that manufactures all natural biodegradable products. They are neither medication or drugs. I am only 15, but I have started on B-Complex (along with others), just 2 capsules a day & that is it you can take more if you are stressed out or even there amplified stress reliever. We need so much because its water soluble & is used up extremely fast, any extra will just be excreted anyways. We need so many supplements because now the world processes food with so many preservatives that diminishes the quality & quantity of nutrients we expect to receive through them.

Wow, that is a lot of Allergies. My advice to you is this. Stop eating the food that you are eating right now and start eating vegetables, fruit, rice, tuna and take Butter made of Olive Oil with your brown bread or biscuits. Do this for 6 months so that your body can be clean up and also do some 20 minutes exercise 3 times a week like streching to improve your blood circulation because it carries oxygen to different parts of your body. Try to avoid using white bread and only eat ones a week meat if you can or avoid it completely because it uses a lot of the blood to brake down the food when other parts of the body needs that blood to protect you from allergy like dust and dust mites. Maybe you grew up in a Clean House that uses different types of Cleaning Chemicals so look around your house and throw away all those Cleaning Chemicals and the Sprays that make the house smell like Perfume do not use them again. Sometimes a Clean House can create lots of sickness like Allergies. Also try to read Books that help you think Positive because it will help you believe in yourself. Sometimes feeling Doubts or not having the right Information specially when a Doctor does not know the answer can make the mind confused and will make the body feel a lot more like a “Phantom Sickness”. You will have to stop eating Pizza, Humburgers, Ice-cream, white bread, saucages, meat, and do not use any more deorant under your arms or any type of perfumes to help reduce your Allergies. Is only for 6 months that you have to follow what I just wrote here, or keep going suffering Allergies and feeling down when Doctors gives you more Medications. Also remember that “Nobody has any interest in your Health except you. No Doctor and No Government has any desire to Actually Make You Well. Keeping you sick makes it easier for them to control and financially exploit you”. So, if you really want to get well make an effort by changing your way of life. If you do not want to stop eating the food you are eating now at least Stop using Permfumes, Deorant under your arms, and Stop cleaning your house with Chemicals because the Corporations does not care if you get sick using their Chemicals that you buy on the Shops. Eat figs with honey when you get a running nose from the Dust.
