A Complete B-Complex to Cover All the Bases

  • Replenish During Times of Stress

    The production of stress hormones burns through a lot of B-vitamins. Increasing your B-vitamin intake can ensure that all of the other systems that rely on B-vitamins get their due.4,5

  • Cell Production and Repair

    A big part of healthy metabolism is making and repairing the cells in your body. B-vitamins keep this process going.8

  • Enhance Energy

    B-vitamins play an essential role in helping the body convert nutrients from food into fuel. They also are needed to produce red blood cells which deliver fresh oxygen throughout the body. B-vitamins promote healthy energy levels, helping you to feel vital and ready for anything.6

  • Promote Healthy Moods

    The energy boost from B-vitamins alone can go a long way in helping with mood. Additionally, the Inositol in our B-Complex help maintain the neurotransmitters that regulate mood such as serotonin and dopamine.7

  • Maintain Brain Health

    The Choline in our B-Complex plays a key role in nurturing the part of the brain involved in memory, learning, logical thinking and concentration abilities. 1, 2, 3

  • Metabolism Optimizer

    B-vitamins help you to burn nutrients efficiently, which is not only important for energy production, but also normal immune function, cell production and a whole host of other things.7

  • Healthy Skin, Hair and Nails

    A variety of B-vitamins, especially Biotin, have been shown to maintain healthy skin, hair and nails.

The Most Complete B-Vitamin Complex: All 8 Standard B-vitamins Plus Choline and Inositol

B-vitamins are the bomb. They play a critical role in converting food into fuel for the body and brain. Certain Bs are needed to produce hormones.1 Others are important for forming red blood cells,2 which are the worker bees of the circulatory system, carrying fresh oxygen throughout your body. If you’ve got that low energy feeling from time to time, a B-vitamin deficiency could be in play.3

Our busy modern lifestyle can diminish B-vitamins like nobody’s business. That’s because your body burns through lots of B-vitamins to create hormones.3-5 While your body pumps out the cortisol and adrenaline necessary to get the monkey off your back, other systems get B-starved. When we’re going through a stressful moment (tax season, we’re looking at you!), we proactively supplement with a B-Complex.

Vegans and vegetarians are at a greater risk of B-deficiency because some of these B-vitamins are most plentiful in animal products.1 In fact, B12 is not found in high levels in any plants.6 Because B-vitamins work synergistically, it’s important to have enough of all of them so that your body can fire on all cylinders. A good B-Complex helps you ensure that you are getting the proper balance.

While most B-Complexes include only the standard eight B-vitamins in the family, the Nested Naturals B Complex adds two cousins: Choline, which is important for memory and brain function,7,8 and Inositol, which has been shown to maintain healthy blood sugar,9,10 mood11,12 and hormone production.13 These two don’t share the same B-names as their cousins, but they are widely accepted as a part of the family and their importance has only recently begun to be understood.

The ingredients inside B-Complex

  • Most Complete B-Vitamin Complex

    Because B-vitamins work best when they are in balance, we don’t leave any out of our formula. In addition to the standard eight B family members, we also include the two awesome cousins: choline and inositol.

  • Vitamin B3 Minus the Nasty Niacin Side Effects

    We use the niacinamide form of B3 because it doesn’t cause flushing or anxiety, which are common side effects of the niacin form of B3.

  • Bioavailable Form of Vitamin B12

    We use the methylcobalamin form of B12. It’s much easier for the body to use than the cheaper cyanocobalamin form.

  • Natural and Non-GMO

    We are relentless about sourcing the best, most naturally sourced, most ethically produced ingredients available. Our B-Complex is 100% non-GMO.

  • Cruelty-free and Vegan

    We’ve made a conscious choice to make our B-Complex 100% vegan. We’re proud of our veggie capsules which are made from “vegetable gelatin” rather than gelatin produced from animal bones and marrow.
