A bioavailable blend of all eight major B vitamins to support energy, brain function, and overall vitality.

  • Full-Spectrum B Vitamin Complex – Provides all eight essential B vitamins, including B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folate), and B12 (methylcobalamin), in their ideal ratios to support whole-body health.

  • Benfontiamine – This blend contains fat-soluble Benfotiamine, vitamin B1, that easily crosses cell membranes for enhanced thiamine bioavailability and cellular support for your body and brain.
  • Biologically Active Forms – Uses activated, coenzyme forms of B vitamins that are ready for your body to absorb and utilise immediately, helping to optimise energy production, mental clarity, and nervous system function.

  • Naturally Bound for Maximum Absorption – Each B vitamin is organically bound to organic quinoa sprouts, with natural cofactors and enzymes, to enhance absorption and retention. This ensures the nutrients remain active and effective for longer than standard synthetic isolates.

  • Supports Energy and Metabolism – B vitamins play a vital role in converting food into energy, maintaining healthy metabolism, and reducing feelings of tiredness and fatigue.

  • Promotes Brain and Nerve Health – Essential for supporting the nervous system, B vitamins aid in neurotransmitter function, mood regulation, memory, and overall cognitive performance.

  • Strengthens Immune and Cardiovascular Function – B vitamins contribute to the normal functioning of the immune system and support cardiovascular health through their role in red blood cell formation and homocysteine metabolism.

Why Supplement with a B Complex?
Poor sleep, low energy, digestive discomfort, brain fog, and mood fluctuations can all be signs of B vitamin deficiency. With modern diets, environmental toxins, and compromised gut health, it’s more important than ever to ensure you’re getting the right balance of these essential nutrients.

Clean, High-Quality Formula:

  • No genetically engineered ingredients

  • Free from magnesium stearate and unnecessary fillers

  • Non-GMO and suitable for daily use

13 Signs You May Be Low in B Vitamins


Low levels of B vitamins can affect your body in many different ways because of the vitamins' far-reaching and interrelated effects. Any one of these common symptoms could be a result of low levels of one or more B vitamins:

  • Inability to sleep well
  • Fatigue and apathy
  • Mental "fog", confusion, and forgetfulness
  • Mood swings and irritability
  • Gastrointestinal symptoms
  • Joint or muscle discomfort
  • Muscle weakness
  • Loss of muscle mass
  • Numbness or tingling in fingers and toes
  • Frequent bruising
  • Headaches
  • Irritability
  • Dry, cracking skin


Because the vitamin B complex is a group of eight major B vitamins that work together, you can impact their synergy just by running low on one. For example, many of the B complex vitamins are needed for healthy skin. If you are low in one or two, that can affect the actions of the others. 

I currently use Vitamin B12 Energy Booster Spray, but the Vitamin B Complex contains B12. Can I take both?


Vitamin B Complex contains 6 mcg of Vitamin B12 or cobalamin, which is more than double the daily recommended amount (by traditional standards). B12 Energy Booster contains 1 mg per serving, which is considerably higher. Many people fall into the high-need group for Vitamin B12 – adults over 50, eating a vegetarian diet or restricting meat, having a digestive issue that might keep you from absorbing B12. If that includes you, we recommend taking both, as the amount in Vitamin B Complex may not provide enough B12.

Who Could Be At Risk For a Vitamin B Deficiency


Certain groups are more likely to have a deficiency or low levels of one or more B vitamins:

  • Those with gut issues (the vitamins may not be absorbed properly) or anyone taking antacids or proton-pump inhibitors, which again could interfere with absorption.
  • Adults over 50 because of lower production of intrinsic factor
  • Those who regularly drink alcohol or more than 4 cups of coffee a day
  • Vegetarians, vegans and others not eating key dietary sources of B vitamins like dairy, meat and whole grains
  • Those regularly consuming a high-calorie, high-carbohydrate diet with low nutrient value


B vitamins in general aren't absorbed well. Add one or more of the above factors and you could easily put yourself at risk for low levels or deficiency. 

One of the key B vitamins whose availability and absorption can be impacted by several of these conditions (especially avoiding animal products) is vitamin B12 or cobalamin. A vitamin B12 deficiency can exist for years under the radar without causing symptoms. By the time you start noticing its classic signs of fatigue, mental "fog", forgetfulness, mood swings, and muscle weakness, you can be significantly deficient.

Because B vitamins are water-soluble and not stored in your body, you must get the entire complex through diet each day. This can be a challenge since many individuals may have absorption issues. Plus, some of the vitamins are easily destroyed during processing and storage.

The Dr Mercola Vitamin B Complex is a unique and complete complex that provides the ideal proportion of the eight major B vitamins:

  • Contains the patented PANMOL vitamin B complex with concentrations of B vitamins a hundred-fold higher than what is found in whole grains
  • The B vitamins are organically bound to sprouts from organic quinoa seeds for enhanced bio-availability and potential benefits
  • Contains more than just the eight familiar B vitamins - It contains a multitude of well-balanced and biologically active B vitamins complete with co-factors and co-enzymes
  • May be better absorbed in your body than regular isolated synthetic B vitamins
  • Contains fat-soluble Benfotiamine that can cross cell walls with greater ease for enhanced thiamine bio-availability and cellular support in your body and brain


This is the first time B vitamins have been created through a patented process where they are organically bound! 

Like a well-oiled machine, B vitamins work together to support energy production and the health of your brain, nervous system, skin and eyes. When you have a limited supply of B Vitamins, your central nervous system (CNS) can be the first to be affected. All of the B vitamins are important for brain and nerve cells, but some stand out for their role in supporting memory, cognitive health and brain performance.
