NOW Foods Vitamin B-100 Sustained Release 100 Tablets

NOW® Vitamin B-100 delivers a comprehensive, well-balanced B-complex — including B-1, B-2, B-3, B-6, B-12, folate, biotin and pantothenic acid at 100 mg levels — along with choline and inositol. The B-vitamins function as a team: they help convert the carbohydrates, fats and proteins in your diet into usable cellular energy, support the formation of healthy red blood cells, and keep the nervous system running smoothly. Getting them together in balanced amounts, as nature intends, helps them work synergistically.* The sustained-release tablet is designed to release the water-soluble B-vitamins gradually over several hours, helping maintain more steady levels rather than a single quick spike.*

Frequently asked questions

What are B-complex vitamins good for?
They work together to help turn food into cellular energy, support healthy red blood cells, and maintain normal nervous-system function — which is why they're often taken as a balanced complex rather than individually.*

What's the difference between B-50 and B-100?
The number reflects the potency level of the core B-vitamins; this B-100 formula provides 100 mg levels of the primary B-vitamins.*

How do I take it?
Take one tablet daily with a meal.*

Cautions & interactions

As with any supplement, talk to your doctor before starting this product if you are pregnant or nursing, take prescription medication, or manage a health condition. Keep it out of reach of children, store it in a cool, dry place, and don't exceed the recommended serving. If you take a multivitamin or several supplements, review the combined amounts with your healthcare provider so you don't unintentionally double up on the same nutrient. B-vitamins are water-soluble and generally well tolerated; any excess is typically excreted rather than stored.
