Zahler

B-Complex Timed Release Tablets Zahler

~~$26.95~~From $21.56

Zahler bioactive B-Complex contains a well-balanced formula of the B Vitamins in body-ready forms for quick and easy absorption

Zahler B-Complex is formulated with a unique two-stage delivery system, with half of the nutrients released immediately and the other half delayed for sustained benefit and enhanced absorption. This advanced formula includes only body-ready (coenzyme, methylated and phosphorylated) forms that don't require complex conversion. The B vitamins are critical for general well-being and specifically support mood, energy, and nervous system functioning.

Advanced Two Stage Delivery:
Zahler's upgraded Bioactive B Complex is a two-layered tablet with layer 1 (half of the nutrients) released and delivered immediately. The delayed release of layer 2 (the other half of the nutrients) enables sustained benefit. Since the B vitamins are water soluble and quickly metabolized and excreted, the benefits of slow release include more stable blood levels and an increase in the total amount of nutrients being absorbed and utilized.

Product FAQs

I noticed that most companies make their B-Complex with much higher doses of the B vitamins. Why does Zahler formulate with such small amounts of each vitamin?

It's not how much you take, it's how much you absorb. Zahler uses the most highly absorbable, body-ready forms of the B vitamins. Since the absorption is so great, it is not necessary for it to contain such high amounts. Additionally, the B vitamins are water soluble and don't stay in the body, so supplementing with higher amounts does not mean that the body gets more. It would only make the body work more to get rid of the excess nutrients.

Is Zahler Bioactive B Complex suitable for those with the MTHFR mutation?

Yes, Zahler Bioactive B Complex contains body-ready forms of the B Vitamins including methylated, phosphorylated and coenzyme forms. Hence, it is suitable for those with the MTHFR mutation.

How many hours apart are the 2 layers of Zahler B Complex released?

The first portion (half the tablet) is released within 30 minutes. The second half will take a few hours. There are differences in the rate of release of the second half between individuals. Majority of the people will have layer 2 working within two to three hours.

Does the B Complex contain Thiamine?

Yes, Zahler Bioactive B Complex contains Thiamine in the form of Benfotiamine. This is the active coenzyme of Vitamin B1, or Thiamine. It is more biologically active and does not require an enzyme-driven bioconversion in the body, which may be impaired in some individuals.

Suggested use

Take one tablet daily with food, or as directed by a healthcare practitioner.

Warnings

You may need additional supplements to support a healthy diet; consult your nutritionist for a formula that is right for you.

Keep out of reach of children. Do not use if safety seal is damaged or missing. If pregnant, nursing or on medication, consult with your healthcare practitioner.

Store tightly closed in a cool, dry place.

B12 Elite 60 lozenges Life Extension

$8.25

Two active forms for brain health & dopamine production, lozenge

Vitamin B12 is essential for brain health and function, energy metabolism and the production of red blood cells. B12 Elite combines two active forms of this crucial vitamin in a single vegetarian lozenge.

What Is B12 Elite?

Vitamin B12 is essential for proper biological processes. Serum levels of vitamin B12 can decline over time, and because it’s found primarily in animal products, vegetarian diets may not provide sufficient B12. Our B12 Elite gives you 500 mcg each of adenosylcobalamin and methylcobalamin: two neurologically active forms of B12.

B12 Elite combines two forms of this vitamin—both of which are essential for proper bodily and neurological function.

B12 Elite Benefits

Novel formula delivers two forms of bioactive B12
Helps protect delicate brain cells
Promotes healthy dopamine levels
Encourages healthy B12 serum levels
Promotes overall brain health

Two Active Forms of Vitamin B12

Vitamin B12 (also called cobalamin) is a water-soluble vitamin that plays a vital role in the health of your nervous system, blood cells and even your DNA (B12 helps protect delicate parts of your chromosomes). Our B12 Elite formula includes two bioactive forms of cobalamin that make it easier for your body to absorb and access vitamin B12’s health benefits.

hy Should I Supplement With B12 Elite?

Whether it's promoting brain health, supporting the nervous system or maintaining cellular health and energy levels, vitamin B12 is essential for us to thrive. But while this vitamin is excellent for our health, more and more of us are finding less and less in our systems because we don't produce it naturally. Changes in eating habits, like relying more on plant-based diets, along with the one thing we can’t change, the passage of time, are also impacting the levels of this vital nutrient.

Luckily, our experts saw the need and formulated our B12 Elite to help you fill in any of your gaps. We didn't just throw any old form of the vitamin in there. B12 Elite uses the active forms of B12. So it's easier for your body to absorb and access the health benefits right away. This tasty vegetarian lozenge has no artificial flavors, colors or sweeteners, and has absolutely no added sugar.

So start promoting your brain health, nervous system, blood cells and more with B12 Elite from Life Extension.

Vitamin B12 is good for you. But many people don’t get sufficient B12 from their diets alone. Reasons range from age-related insufficiency to dietary intake: B12 comes primarily from animal sources, so those following a vegetarian diet may not get enough.

Our new B12 Elite combines two types of cobalamin: adenosylcobalamin and methylcobalamin. These are “active” forms—meaning your body can make use of them right away.

Adenosylcobalamin helps preserve neuronal function

Leucine-Rich Repeat Kinase 2 (LRRK2) is a type of enzyme that modifies other proteins by adding phosphate groups. Inhibiting the activity of this enzyme has been associated with helping to preserve neuronal tissue.

A series of preclinical studies has shown that the adenosylcobalamin form of B12 can inhibit the activity of multiple LRRK2 variants in neurons by decreasing phosphorylation (the addition of phosphate groups to amino acids).

These studies found that adenosylcobalamin helped regulate healthy release of dopamine, a neurotransmitter that plays an important role in cognitive functions such as motor control, arousal, reinforcement and reward.

A cofactor for energy metabolism

Adenosylcobalamin is active in the mitochondria, the powerhouses of your cells. It’s required as a cofactor for the synthesis of succinyl-CoA, a compound that supports cellular energy metabolism.

Methylcobalamin for cellular health & beyond

Methylcobalamin is another neurologically active form of B12 (though in different ways than adenosylcobalamin). Methylcobalamin supports the central nervous system, and it’s essential for the replication and growth of cells.

Methylcobalamin helps to maintain already healthy homocysteine levels. Inhibiting excess levels of this compound is key to maintaining healthy cardiovascular and neurological function.

B12 for a healthy brain and more

This B12 formula combines methylcobalamin and adenosylcobalamin to offer optimal cognitive support. Want the health benefits of the full range of the B vitamins? We also offer our BioActive Complete B-Complex formula: a wide-spectrum of B vitamins for whole-body health.
