B12 FAST® Sublingual Spray
Premium Vitamin B12 oral spray with advanced sublingual technology.
B12 FAST® is a high-strength sublingual Vitamin B12 supplement developed with advanced oral-spray technology to deliver rapid absorption through the tissues beneath the tongue. Unlike conventional tablets, the sublingual delivery system bypasses much of the digestive process, allowing Vitamin B12 to become available more quickly — a convenient daily option for people who prefer not to swallow tablets.
Food supplement. Made in the United Kingdom under strict GMP standards. Suitable for vegetarians and vegans.
Why a sublingual spray?
The area beneath the tongue is rich in fine blood vessels. A sublingual spray places Vitamin B12 directly onto this tissue, so it can begin to be absorbed without first passing through the full digestive process required of tablets and capsules. For many people this makes the spray format both faster and more convenient.
Each spray delivers a high-strength 1000 mcg dose of Vitamin B12 as methylcobalamin — the biologically active form widely used in premium nutritional formulations. No water is needed, and the compact bottle is easy to use at home, at work or while travelling.
