Place the B12 sublingual supplement under your tongue and let it dissolve as directed on the package. Follow the product’s instructions if they specify a different method, and don’t take extra doses to make up for a missed one.
Usually, swallowing a B12 sublingual supplement is not dangerous, but it bypasses the way the product is intended to be taken. Let it dissolve under your tongue unless its directions specifically allow swallowing.
A B12 sublingual supplement has not been shown to work faster or be more effective for everyone than a swallowed B12 pill. Both can provide B12; the right choice depends on the product and your reason for taking it.
Yes, you can take a B12 sublingual supplement at night if that suits your routine. Some people report feeling more alert after B12, so if it seems to disrupt your sleep, take it earlier in the day.
A B12 sublingual supplement may improve B12 levels over time, but symptom relief can take longer and varies with the cause and severity of deficiency. A clinician can monitor levels and advise on treatment duration.
Yes, a B12 sublingual supplement can generally be taken with a multivitamin. Compare their B12 contents so you know your total intake, and ask a healthcare professional if you take prescription medicines or are treating a diagnosed deficiency.
A B12 sublingual supplement is usually well tolerated, but some people experience nausea, headache, or a skin reaction. Stop taking it and seek medical advice if you develop a severe or persistent reaction.
Yes, a B12 sublingual supplement can help vegans obtain vitamin B12, which is not reliably supplied by unfortified plant foods. Check that the product’s ingredients, including flavorings and other additives, suit your preferences.
Both methylcobalamin and cyanocobalamin are common forms in a B12 sublingual supplement, and neither is established as the best choice for everyone. Consider the dose and product directions rather than assuming one form works better.
A B12 sublingual supplement can interact with some medicines, and certain medicines can affect B12 levels. If you take regular medication or have a condition being treated, ask your doctor or pharmacist before starting it.

A B12 sublingual supplement is a product containing vitamin B12, made to dissolve under the tongue rather than being eaten as a meal or mixed into a drink. It may come as a small tablet or lozenge, and the format and directions can vary by product.
Place it under the tongue and let it dissolve according to the label; flavour and texture differ between brands. Some people take it alongside breakfast, while others choose another convenient time. The listed nutrition figures are per 100 g, whereas a typical piece is only about 1 g, so the table may not reflect much about an everyday serving. Check the product directions, and ask a health professional if you are unsure whether it suits you.
Very high
How many vitamins, minerals and how much fiber this food carries per calorie. A high score means a lot of nutrition for few calories.
Low
An EatBetter score computed from fiber, protein and calorie density. A high score means staying full longer on the same calories.
Both scores are calculated per 100 g and do not change with the selected portion. The satiety score is EatBetter's own calculation, not a clinical measure.
