Metab-12 is a liquid supplement containing vitamin B12 in its methylcobalamin (Methyl B12) form and vitamin D3 (cholecalciferol). It comes in a pleasant berry flavour and is designed for sublingual absorption — placed under the tongue for direct absorption into the bloodstream.

Shake gently before use. Place the contents of one full dropper (1 ml) under the tongue and hold for 20 seconds before swallowing. Use once per day. Sublingual absorption allows the vitamins to enter the bloodstream directly, which may be beneficial for people who have difficulty absorbing nutrients through the digestive tract.

Vitamin B12 contributes to normal energy-yielding metabolism, normal functioning of the nervous system, normal red blood cell formation, the reduction of tiredness and fatigue, and normal immune system function. It also plays a role in normal homocysteine metabolism and normal psychological function.

Each serving of Metab-12 provides 20 mcg (800 IU) of vitamin D3, which is 100% of the recommended daily value. Vitamin D contributes to normal absorption of calcium, the maintenance of normal bones and teeth, normal muscle function, and normal immune system function. Vitamin D3 is the most bioavailable form.

Metab-12 may be particularly helpful for people who have difficulty swallowing tablets or capsules, as it is a liquid taken sublingually. It may also be suitable for people with reduced digestive absorption. Vitamin B12 deficiency is relatively common, especially among older adults and those following a plant-based diet.
