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

PURE & CLEAN -

we use hypoallergenic ingredients with no unnecessary additives; UK GMP-manufactured, certified vegan, non-GMO & compatible with halal and kosher diets

Explore the formula

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.

B12 strength	1000mcg per daily dose	Varies
Daily dose	1 small tablet	Varies
Artificial colors, flavors or preservatives	No	Often

What to expect

Magnesium and L-theanine build steadily — here's a realistic timeline of how your family may notice the difference.

What you may notice

You may notice improved energy and reduced tiredness within the first few weeks, particularly if your B12 status was previously low.

With consistent use

Replenishing low B12 takes time. Consistent use supports healthy B12 status, energy metabolism, red blood cell formation and nervous system function.

Good to know

Let the tablet dissolve slowly under your tongue rather than swallowing it whole, to make the most of the sublingual format.

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.

Natural strawberry flavour

With a natural strawberry flavour and pleasant taste from natural sweeteners mannitol and stevia, Super B12-Complex is easy to use. The small tablets have a smooth texture, sitting comfortably under the tongue. Our formula is free from sugar and free from artificial sweeteners, colours and flavours.
