Why B Complex Plus Works?

Without B vitamins, hundreds of cellular reactions could not take place. Amongst many things, B vitamins are frequently used as coenzymes. They help power the enzymes that metabolize food into cellular energy (ATP) and regulate the methylation cycle. For example, a significant enzyme complex transforms glucose into ATP called the Pyruvate Dehydrogenase Complex. Embedded in this important group of proteins are various B vitamins. They pass pyruvate along, facilitating its transformation into acetyl CoA, which enters the Krebs cycle to generate energy (ATP). Vitamins B1 (thiamin), B2 (riboflavin), B3 (niacin), and B5 (pantothenic acid) all play crucial roles in transforming glucose from food into energy used to power us throughout the day.

When it is time to rest, digest, detox, and repair, our methylation cycle helps to produce melatonin, dopamine, bile, and phosphatidylcholine. To function optimally, methylation cycle enzymes depend on vitamins B2 (riboflavin), B6 (pyridoxine), B9 (folates), B12 (cobalamins), and choline. Methylation enzymes/proteins cannot achieve the correct shape needed to facilitate healthy sleep, mood, digestion, and cellular repair if these critical nutrients are missing. There are thousands of processes occurring in your body every second that could not happen without the help of the essential B vitamins. B Complex Plus provides all of the essentials plus choline. The potent levels and biologically active forms found in B Complex Plus support your enzymes and cells to function optimally.

Product Information & FAQ's

Who Needs B Complex Plus

Did you know that you need B vitamins every day? That’s because your body doesn’t store these water-soluble vitamins. Nearly every biochemical process in your body is in some way dependent upon B vitamins. There are eight B vitamins considered essential because your body cannot make them. Vegan and vegetarian diets tend to be lower in some of these essential nutrients. Those with certain genetic mutations, such as MTHFR or MTRR variations, may have difficulty obtaining them from food alone. Without adequate B vitamins, you might be struggling with low energy levels, elevated homocysteine levels, and inadequate methylation.

B Complex Plus is a potent vitamin B complex supplement. It provides active forms of the 8 essential B vitamins plus choline for additional methylation support. B Complex Plus is an excellent option if you’re looking for a high-strength, one-a-day B complex dietary supplement. It contains over 100% of the daily value for all eight essential B vitamins. This formulation is ideal for those who are deficient or are looking for higher levels of B vitamins in their supplement. B Complex Plus includes 680 mcg DFE (400 mcg) of the active, methylated form of folate. Active folate is known as 5-methyltetrahydrofolate (5-MTHF). It is the only form of folate that crosses the blood-brain barrier. It supports MTHFR gene variations and healthy methylation throughout your body. Folic acid is never included in any Seeking Health dietary supplements. This artificial version of folate is not well utilized by the body. It can even contribute to folate deficiency and other adverse side effects!

B Complex Plus also includes 50 mcg of vitamin B12 in the bioavailable forms of methylcobalamin and adenosylcobalamin. Here at Seeking Health, you’ll never find the cyanide-containing form of B12 known as cyanocobalamin. Before being used, your liver must first convert it into an active form and discard the cyanide. It appears that methylcobalamin may be a gentler option that the body can use more efficiently than cyanocobalamin.* Bioavailable forms of B vitamins promote healthy:

  • Immune system function
  • Energy production
  • Hormone balance
  • Positive mood
  • Nerves and brain
  • Red blood cells 
  • Homocysteine levels

Choline is a source of methyl groups. It is included in this super B-complex to support methylation. It appears to play key roles in healthy nervous system and brain function, liver and heart health, and cell membrane formation. B Complex Plus contains potent amounts of your daily essential B vitamins in bioactive forms plus choline. This formula is gluten-free and free of GMO markers. It is ideal for those experiencing deficiency or in need of higher amounts of B vitamins. It supports a healthy methylation pathway and nearly every biochemical process in your body. Get ready to tackle the day with this powerful, energy-supporting formula!

Are there any warnings or side effects when using B Complex Plus?

Side effects of B vitamins may uncommonly include:

  • Nausea
  • Orange urine
  • Stomach upset
  • Rash 
  • Flushing
  • Itching
  • Mild fever
  • Sometimes stomach upset

Individuals who have recently undergone surgery for a coronary stent should avoid using B12. 

B Complex Plus contains niacin - if you are sensitive to niacin, you may experience a "flush" sensation when using B Complex Plus. This is a result of the niacin dilating blood vessels and increasing circulation under the surface of the skin. This can cause redness, a sensation of warmth, itching, tingling or sometimes a pulsating sensation - especially in the face or neck, or the upper torso. 

If you believe that you are experiencing any adverse reactions, please see your healthcare professional immediately. Each individual may react differently to any product or supplement. We always recommend that you consult with your healthcare professional prior to considering the use of B Complex Plus or any supplement.


Children and pregnant or lactating women should consult their healthcare practitioner prior to use. Do not use if tamper seal is damaged. When taking high doses of nutrients such as B12 and folate, monitor blood levels and use under the supervision of a qualified physician.

Niacin Flushing

This formula contains niacin. When taken on an empty stomach, a healthy response to niacin supplementation may include mild blushing, warming, or tingling of the skin. This can appear on the ears, face, arms, torso, or occasionally on the legs. Commonly referred to as a "niacin flush", this harmless response normally dissipates within an hour. It is related to niacin's role in vasodilation (widening of blood vessels). Vasodilation leads to better circulation, capillary flushing, and increased blood flow to the surface of the skin. To minimize or prevent flushing, consider taking this supplement with food or in divided doses.

Who is B Complex Plus intended for?

B Complex Plus is intended for those needing all the essential B vitamins in potent doses, to support deficiencies, diets lacking in B vitamins (vegan or vegetarian diets), or needing comprehensive methylation pathway support.

Does B Complex Plus contain corn, yeast, gluten or grains?

B Complex Plus is gluten-free. B Complex Plus does not contain grains or yeast. However, this formula contains ascorbyl palmitate ("Other Ingredient") which is derived in part from highly purified corn oil. Due to the processes used to manufacture the finished ingredients, the ascorbyl palmitate is free from corn proteins.

Is B Complex Plus free from GMOs?
