Filling this nutritional gap can make a huge difference on your daily amount of energy. However, pay attention to how much vitamin B is in your supplements. If you are already getting enough in your diet, you don't need a huge amount. Always contact your doctor with your concerns before starting any type of vitamin supplement.  Vitamins will specify if they are vegan, dairy-free or gluten-free. If you have any of these dietary preferences or restrictions, look for vitamins that are made without gluten, dairy or animal products. While dietary supplements aren't regulated by the FDA, there are a few verifications you can check for that ensure the product you're buying is safe to use.Those verifications include:The vitamin supplements for this list were selected based on price, accessibility, quality, and vitamin and mineral quantities. We also took into account third-party verifications, dosage and customer reviews. The vitamins that made this list are the best of the best out there right now.   The eight B vitamins (thiamin, riboflavin, niacin, pantothenic acid, B6, biotin, folate and B12) provide the most energy, as they aid in cell metabolism, help the body transform carbohydrates and fats into energy and carry energy-nutrients around the body. B12 and B complex are both very important. However, with B12 supplements, you are only getting one B vitamin, and with B complex supplements, you are intaking all eight B vitamins. If you lack B vitamins from your diet, consider a B complex vitamin. If you are B12 deficient, a B12 supplement may be better for you. As much as we wish this were true, it is not. Taking a B12 supplement or any vitamin B supplement will not give you energy right away like a cup of coffee. Instead, it could take a few weeks of taking B12 regularly until it increases your energy levels.
