None of the water soluble vitamins (e.g. B complex, C) can produce toxicity.
Niacin, one of the B vitamins does produce a very unpleasant "flushing" at very high doses, but although unpleasant is not a result of toxicity. However these high doses of niacin should only be under a doctor's supervision.
No overdose toxicity is observed. This is because vitamin B can easily be excreted in urine.
vitamins and supplement
A deficiency of B-12 leads to anemia, not gout.
Vitamin A comes in two forms: Retinol/Retinaldehyde and Beta-Carotene. Retinol/Retinaldehyde comes from animal sources while Beta-Carotene comes from plant sources. Only Vitamin A in the form of Retinol can be toxic or "over-dosed". This is because Vitamin A in this form is fat-soluble. Thus, when you consume over 100% of the recommended daily value, the rest is stored in your fat and organs, and thus can build up in your body and cause Vitamin A toxicity. Vitamins A,D,E, and K are the fat soluble vitamins and can all cause toxicity. However, Vitamin C and the B-vitamins (folate/folic acid, thiamin, riboflavin, niacin, cyanocobalamin etc) are the water soluble vitamins. Thus, when you consume over 100% of the recommended daily value, you excrete the rest in your urine and feces. It is EXTREMELY difficult and rare to find a toxicity of the water-soluble vitamins for this reason. Remember though, Vitamin A in the form of Beta-Carotene can not cause Toxicity because it is not fat soluble. Generally, the nutrition community will refer to Vitamin A in the Retinol/Retinaldehyde form in current texts and Beta-Carotene as its own entity.

Vitamin B is not considered harmful for those suffering with Lyme disease. In fact, supplements are often recommended as the disease can lead to nutritional deficiencies.
Excess of vitamin intake or vitamin overdose is called hypervitaminosis. It is a condition of high storage levels of vitamin, which can lead to toxicity.Hypervitaminosis A is an excess of vitamin A, Similarly Hypervitaminosis C an excess of vitamin C, and so on.High or toxic levels of vitamins occur when you have high supplement intake and when you do not take from dietary sources.
Vitamin B is a water soluble vitamin meaning that it is not stored in the body. Your body will use what it needs and flush the remainder out in the urine. Water soluble vitamins need to be replaced on a regular basis. As with any vitamin you should always follow the manufacturers recommended daily dosage. By doing this you will not run into problems. However, Vitamin D being fat soluble, means that it does not get flushed by the kidneys if consumed in excess, and stored within the liver predominantly.
Vitamin B12 is considered predominantly in food of animal origin. However, other members of the Vitamin B group - Vitamin B 1, - Vitamin B 2, - Vitamin B 3, - Vitamin B 5, - Vitamin B 6, and - Vitamin B 8 are also found in food of animal origin. Food sources for these vitamins are detailed in the related links.
