Top 7 Best Sublingual B12 Supplements

Written by Andrew Le, MD

UpdatedNovember 13, 2024

Vitamin B12 is an important nutrient that is essential in supporting normal functioning of the nerves, DNA replication and the formation of red blood cells. It is naturally present in animal foods, which means that people who eat a plant-based or low-animal diet are likely to be deficient in this nutrient. This is where sublingual B12 supplements come in handy.

Sublingual B12 supplements are formulated in a manner that, when placed under the tongue, their absorption is quicker and more efficient than a regular B12 supplement that goes through the digestive system. It is a perfect format for people to use to get extra doses of their B12 that they may not be able to absorb or get through the foods they eat.

Buying Guide

There are certain factors that one needs to look for when searching for the best sublingual B12 supplement.

Form of B12

The two primary types of B12 found in sublingual supplements include cyanocobalamin and methylcobalamin. Cyanocobalamin is the synthetic form of B12 and is often less expensive. However, some individuals are not able to convert it to methylcobalamin, which is utilizable in the body. Methylcobalamin is the active form of B12 and this form is more assimilated by the body compared to others. If you are in doubt as to which form you should choose, you should consult with a healthcare professional.

Dosage

The daily allowance of B12 depends on age, sex, and other conditions. Opting for the right supplement requires choosing one that meets the right dosage for the user. Excessive intake of B12 is toxic, and thus, you should use the recommended dosage as indicated on the packaging.

Ingredients

Read the list of other ingredients that can be included in the supplement, like fillers or additives, which can be completely unnecessary or may lead to an allergic reaction. Choose a supplement that contains essential and natural nutrients.

Brand Reputation

Surf the internet to learn more about the brand and look for customers’ experiences. Try to find a brand that does not hide the way it produces its products and uses quality raw materials.

Frequently Asked Questions

What is the recommended daily dosage for sublingual B12 supplements?

The required dosage of sublingual B12 each day depends on age, gender and specific requirements of the body. However, the general recommended daily dosage is about 1000-2000 micrograms a day.

Which is better for absorption: methylcobalamin or adenosylcobalamin?

Methylcobalamin and adenosylcobalamin are equally efficient forms of B12 for absorption. However, methylcobalamin is more frequently used in sublingual B12 supplements because this form of the vitamin is stable and effective in the body.

Are there any side effects associated with taking sublingual B12 supplements?

This type of B12 supplement is safe and rarely causes negative side effects. However, some people may have minor side effects like nausea, headache, or diarrhea after administering the drug. Always seek advice from a healthcare provider before consuming any new supplement.

Can sublingual B12 supplements be taken by vegans?

Yes, sublingual B12 supplements are ideal for vegans as they present a source of B12 that is not sourced from plants in any way.

Are sublingual B12 supplements more effective than other forms of B12 supplements?

Another method of supplementing with B12 is using sublingual B12 supplements. However, it is still important to note that the efficacy of sublingual B12 supplements compared to other forms of B12 supplements may differ from one user to another depending on their absorption rate. You should first consult your healthcare provider for advice on which kind of B12 supplement is suitable for you.
