So, is it really necessary to have high amounts of B Vitamins? Lets start off by saying that B Vitamins are water soluble, and most times your body will take what it needs and throw the rest away via your urine. Your body can hang onto the B vitamins for up to a few days. High doses of certain B vitamins can be toxic.

B 3: Skin flushing and or pain; liver toxicity and elevated blood sugar. Nausea, jaundice, elevated liver enzymes. (You shouldn't take high doses of B3 (niacin) if you’re pregnant, have ulcers, gout, diabetes, gallbladder disease, liver disease, or have had a heart attack recently.
B 6: Nerve damage, or numbness in limbs or skin lesions.
B 9: Kidney damage, masking of B12 deficiency
B 12: Acne or rosacea in some people
High doses of B Vitamins are often found in energy drinks, and the problem with these is they are synthetic, and vitamins in high doses, with high sugar content in some, and taurine. Take for an example a Monster drink has 100% of daily requirements of Vitamins B2, B3, B6, B12. All synthetic. If you are feeling lethargic daily, you may have something else going on and should see your healthcare provider.

Most times, eating foods rich in these essential vitamins is adequate enough for optimal health. If you body has issues absorbing certain nutrients, or are deficient, supplementation may be required.
