    A Complete B-Complex to Cover All the Bases

  • Replenish During Times of Occasional Stress

    The production of stress hormones burns through a lot of B- vitamins.4 Studies suggest that B-vitamins can combat occasional work stress and promote cognitive performance.11,12 Increasing your B-vitamin intake can ensure that all of the other systems that rely on B-vitamins get their due.

  • Immune System Stimulation

    Several B-vitamins are involved in supporting the immune system. A supported immune system promotes overall health and wellness.16

  • Energy Boost

    B-vitamins play an essential role in helping the body convert nutrients from food into fuel.13 They also are needed to produce red blood cells which deliver fresh oxygen throughout the body.2 B-vitamins are natural energy boosters, helping you to feel vital and ready for anything.

  • Mood Enhancement

    The energy boost from B-vitamins alone can go a long way in helping with mood.14 Inositol and other B-vitamins in our B-Complex help the neurotransmitters that support positive moods such as serotonin and dopamine.6

  • Brain Health

    A variety of the B-vitamins have been linked to maintaining brain health.15 The Choline in our B-Complex plays a key role in supporting the part of the brain involved in memory, learning, logical thinking and concentration abilities.8

  • Metabolism Optimizer

    Many of the B-vitamins assist with the breakdown of the foods you eat. This includes carbohydrates, proteins and fats. This is important for overall health and weight management.13

  • Healthier Skin, Hair and Nails

    A variety of B-vitamins, especially Biotin, have been shown to possibly protect and promote healthy skin, hair and nails.13

Nurture Healthy Energy, Mood and Metabolism Especially for People Under Stress, Vegans and Vegetarians

The most complete B-vitamin complex, with all eight 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, which are the worker bees of the circulatory system, carrying fresh oxygen throughout your body.2 If you’ve got that low energy feeling all the time, a B-vitamin deficiency could be in play.

Stress will deplete your B-vitamins like nobody’s business. That’s because your body burns through lots of B-vitamins to create stress hormones.3,4 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. In fact, B12 is not found in high levels in any plants.5 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, and Inositol, which has been shown to help maintain healthy blood sugar levels and promote positive moods.6-8 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. 

We’re excited to offer the most complete B-Complex available and we’re proud that it’s 100% vegan and non-GMO.    

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 B3.9

  • 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 which the body must use to convert.10 Only the best for our friends and customers!

  • Non-GMO

    We are relentless about sourcing the best, 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.
