After taking B-complex I feel a loss of energy and very sleepy is that ...

Vitamin B complex is nothing but a combination of a certain amount of some of the B vitamins. It is usually recommended when a person has to combat a deficiency of vitamin B but one should note that this rarely has any side effects. Furthermore, if taken in the prescribed dosage, B complex is mild enough not to have any kind of observable side effects. At the same time, symptoms like fatigue are possible on account of certain individual vitamins which are included in B complex, such as riboflavin. However, this is just one of 8 vitamins which may be found in the vitamin B group, that make up B complex. Therefore it is imperative that you speak to your doctor about the loss of energy and the drowsiness experienced after taking these vitamins. It would be advisable to stop these until you see the doctor and report any differences observed without the B vitamins. There are certain general things to report to the doctor when taking any medication, such as history of certain ulcers, pregnancy, breastfeeding and other medications. It is important to report these to your doctor, since taking such vitamins may be inadvisable if you have such conditions.

One also has to remember that the B vitamins may be obtained from a variety of both non-vegetarian as well as healthy vegetarian sources. Talk to your doctor about specific B vitamins that you might be lacking if you feel the need for B complex. For instance, meat would be great for getting more B12, B2, B3, B5 as well as B6. There are different other sources of some B vitamins, such as green leafy vegetables, nuts and beans. While these are some of the vegetarian sources, other non-vegetarian foods rich in such vitamins include eggs, fish and liver. Milk and other dairy products make good sources of such B vitamins and one should try to include all kinds of healthy sources of these vitamins. In this way, you might be able to avoid taking the B vitamin supplements altogether and you would not have to experience those symptoms. Talk to your doctor about the possible alternatives and get a checkup to see whether the symptoms might be attributable to other causes, such as anemia. It could be that your nutritional sources are lacking in iron and that this has led to a condition of anemia which has made you so tired and sleepy.
