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.†

Eight B vitamins are 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 deficient or 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!†

Inside the Uncompromising Quality of Our Ingredients

  • Active Folate (Quatrefolic®)
    Two natural folates are added by Dr. Lynch. There is no unnatural folic acid. L-methylfolate supports healthy methylation while folinic acid supports healthy blood cells, platelets, skin and neurotransmitters.†
  • Bioavailable Folate & B12 (MecobalActive®)
    Methylated folate and B12 support healthy homocysteine levels, cardiovascular health, methylation processes, energy production, detoxification and MTHFR variations.†
  • Riboflavin (Vitamin B2)
    This B vitamin recycles damaged and used-up glutathione by supporting your glutathione reductase (GSR) enzyme.†
  • Niacin
    Vitamin B3 is a building block for NAD+, which are essential in the Krebs cycle for energy production. It also supports circulation, MTRR enzyme function, healthy lipid levels and joint lubrication.†
  • Vitamin B6 (P-5-P)
    This active form of vitamin B6 is involved in over 140 different enzymatic reactions in the body. It supports healthy ammonia levels, absorption of magnesium into red blood cells, neurological function, serotonin synthesis and hormone metabolism, as well as homocysteine and glutathione formation.†
  • Thiamin
    Vitamin B1 supports healthy carbohydrate metabolism and detoxification.†
  • Biotin
    Supports healthy skin and nails.†
  • Vitamin B5 (pantothenic acid)
    Essential for proper cortisol regulation and adrenal function. It is also a cofactor for the NAT2 enzyme, which metabolizes histamine to acetyl histamine and eliminates it in the urine.†
  • Choline (as phosphatidylcholine and choline bitartrate)
    Our soy-free blend protects vitamin C through the GI tract. This greatly enhances cellular bioavailability, delivery, and absorption. It can also reduce the GI side effects experienced with some vitamin C supplements.†

MecobalActive® is a trademark of HEALTHTECH BIO ACTIVES, S.L.U. Quatrefolic® is a registered trademark of Gnosis S.p.A. Produced under US Patent No. 7,947,662.

    Amazing, High Quality Product!!!

    My daughter was 13 when she unexpectedly began experiencing seizures in June 2024. After many appointments and tests, her doctors were unable to identify a specific cause. By November, the seizures were happening weekly, sometimes twice a week and we were searching for anything that could help us better understand what was going on.

    Through our own research and with guidance from a functional doctor, we learned that she has an MTHFR gene mutation, which for her meant that supporting healthy vitamin B metabolism was important. Her doctor recommended Seeking Health products, so she began taking Vitamin B Complex Plus along with the multivitamin on February 15, 2025.

    Her last seizure occurred on March 1, 2025. While we cannot say what may have contributed to the changes we’ve seen, we are incredibly grateful to have found a routine that supports her overall wellness. She takes her supplements faithfully every day, is now 14, thriving, and we are hopeful as we approach the possibility of one year without a seizure.

    This has been a long and emotional journey, and I wanted Seeking Health to know how meaningful it has been to have products that support her nutritional needs. Thank you from the bottom of my heart!
