Super B12-Complex has been expertly formulated to effectively raise cellular levels of this essential nutrient. The superior sublingual format delivers vitamin B12 directly to the bloodstream, bypassing absorption challenges in the gut. Different forms of B12 are required in different areas of the body, so we provide three naturally occurring and bioactive forms - methylcobalamin, adenosylcobalamin and hydroxocobalamin - for greater health coverage.

THREE SUPERIOR FORMS OF B12 -

we provide three naturally occurring and bioactive forms of B12 - methylcobalamin, adenosylcobalamin & hydroxocobalamin. No synthetic cyanocobalamin

ENHANCED ABSORPTION -

sublingual delivery boosts absorption by delivering vitamin B12 directly into the bloodstream via passive diffusion under the tongue, bypassing absorption challenges in the gut to achieve higher B12 levels

SUPPORTS ENERGY, BRAIN FUNCTION & RED BLOOD CELLS -

an effective 1000mcg is ideal for supporting energy levels & metabolism, the central nervous system & mood, and red blood cell production

SUGAR-FREE NATURAL STRAWBERRY FLAVOUR -

no sugar, artificial sweeteners, colours or flavours. A pleasant taste from natural sweeteners mannitol and stevia, the small one-a-day tablets dissolve comfortably under the tongue

Enhanced absorption bypasses the gut

Standard absorption of vitamin B12 via the gut relies on several factors that can easily be compromised, and is limited to small quantities of B12 at any one time. Absorption is usually reliant on adequate stomach acid to detach B12 from proteins in the diet, and the presence of intrinsic factor (IF) - a binding protein which supports absorption in the intestines. Levels of stomach acid and IF are often reduced by medication, genetic variations, digestive disorders and ageing, leading to reduced B12 uptake.

Sublingual delivery for high uptake

We use the superior sublingual format to bypass the digestive system, avoiding any absorption issues which may be present. Sublingual delivery allows vitamin B12 to be absorbed directly into the bloodstream via passive diffusion under the tongue, as efficient as B12 injections. This superior uptake mechanism is ideal for those who may have suboptimal digestion. Each small tablet delivers an effective 1000mcg B12 in a convenient 1-a-day dose, ideal for supporting B12 levels without oversaturating the body.

Three superior forms of B12

Standard B12 supplements often deliver a single form of B12 as synthetic cyanocobalamin, a poorly absorbed form. To provide superior bioavailability and retention, we combine three naturally occurring and bioactive forms - methylcobalamin, adenosylcobalamin and hydroxocobalamin. These forms of B12 are also required for different functions in the body, offering greater health coverage. Those with genetic variations may also benefit from taking multiple forms to raise B12 status more efficiently.

Energy production & brain function

Each form of vitamin B12 is required for different functions in the body, so we combine 3 forms for whole-body health benefits. Adenosylcobalamin is active in mitochondria, the powerhouse of cells, where it contributes to normal energy-yielding metabolism. Methylcobalamin is a cofactor in homocysteine recycling, essential for neurotransmitter function, contributing to normal psychological function.

Supports a plant-based diet

As vitamin B12 in the diet is mainly present in animal foods, followers of a plant-based diet may struggle to meet their daily needs. Both low intake and poor absorption of vitamin B12 often lead to symptoms of fatigue and poor energy. Supplementation provides a convenient way to ensure your daily needs can be met. This vegan formula provides naturally occurring, bioactive forms for optimal benefits.
