Excellent Quality and Value

I switched to this B complex from another brand due to a recent micronutrient panel that gave me targeted information on which B vitamins I was most in need of. I trust Seeking Health to always have the very best quality, and found this supplement to provide a very balanced ratio. ~El

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!

Key Ingredients

Inside the Uncompromising Quality of Our Ingredients

  • Active Folate
    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
    Methylated folate and B12 support healthy homocysteine levels, cardiovascular health, methylation processes, energy production, detoxification and MTHFR variations.
  • Riboflavin (Vitamin B2)
    This is the MTHFR gene cofactor, which produces the active form of folate. Supports hormone balance, nervous system function, cellular energy production and glutathione recycling. It is a cofactor for the MAOA enzyme, helping metabolize dopamine for feelings of calm. Also aids in healthy serotonin and histamine levels.
  • 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.

    Great for Energy

    My husband and I both use these. I typically take mine in the morning and they often support a clear head upon waking. As time goes on, I do find that I need them less if I have a more sedentary day. But if I am going to be active at all throughout the day, they are tremendously helpful. I have been experiencing a healthy response to the "crash and burn" effect of rigorous activity since starting these a couple months ago. My husband likes to take his at lunch to maintain stable energy levels throughout the afternoon in his job which requires a fair amount of physical labor. If I could change anything, though, I wish there were a half dose option available. Perhaps I could also try methyl free b vitamins for the less active days, because I do notice irritability if I take the methyl bs and don't move around afterward.
