Vitamin B Complex Sublingual Liquid

So you’ve heard of supplements containing “vitamin B complex,” but what exactly does that mean? If you’re like us, you want to know that every ingredient inside your supplements is there for a reason, that reason being to help maintain your body’s health. So, before diving into the specifics about sublingual vitamins, let’s explore the term vitamin B complex and what this important group of vitamins does for your body.

Vitamin B complex refers to a combination of the eight B vitamins: thiamine (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), pyridoxine (B6), biotin (B7), folic acid (B9), and cobalamin (B12). Each B vitamin has its own role to play within the body, and the daily recommended doses for each type may vary. However, despite having unique duties, most of the B complex vitamins share a similar purpose in boosting cell metabolism, brain function, and energy levels. A supplement that contains vitamin B complex should typically include your daily recommended amount of each one of these 8 vitamins, making it a convenient way to give yourself some added nutrition without having to switch up your diet.

Oftentimes, you will see supplements labeled as “sublingual liquid B complex.” The word “sublingual” may sound complicated at first, but all it means is that instead of dispersing the liquid supplement on top of your tongue or into a beverage, you place it directly beneath the tongue. Studies have shown that taking supplements sublingually may result in slightly faster absorption compared to ordinary liquid supplements, which already boast faster absorption than solid options like pills and tablets (1). This is just one of the many vitamin B complex sublingual benefits, which we will discuss in more detail throughout the next section.

Read on to learn about vitamin B complex sublingual liquid supplements, some of the best ways to take them, and more potential benefits they may have on your overall health and wellness.

Best Sublingual Vitamin B Complex

The best sublingual vitamin B complex should be one that contains your daily recommended amount of each of the B vitamins. If you have a deficiency in one of the B vitamins, then your dosage may need to be higher. No matter what, you should always consult with your physician before adding a new supplement to your ordinary routine. Below, we have listed the recommended daily intake (RDI) in adults for each B vitamin: 

  • Thiamine (B1): 1.1 mg
  • Riboflavin (B2): 1.1 mg
  • Niacin (B3): 14 mg
  • Pantothenic acid (B5): 5 mg
  • Pyridoxine (B6): 1.3 mg
  • Biotin (B7): 30 mcg (not RDI, Adequate Intake)
  • Folate (B9): 400 mcg
  • Cobalamin (B12): 2.4 mcg

While vitamin B complex sublingual tablets are available and effective, one of the best sublingual B complex options for prioritizing fast absorption is to choose the liquid variety. With a liquid supplement, nutrients are already present in their liquid forms, allowing them to be absorbed directly into the bloodstream without much need for digestion or processing from the body. On top of that, a tablet may take extra time to dissolve and could leave a somewhat unpleasant, mineral-y taste behind in your mouth. 

Best Vitamin B Complex

Just like any sublingual options, the best vitamin B complex in general will also contain the RDI for each of the 8 B complex vitamins. Outside the sublingual realm, there are plenty of options when it comes to these supplements. Which one you decide to take may depend on your reasons for taking it as well as any extenuating circumstances in your life. For example, making the choice between vitamin B complex liquid vs pill could take into consideration such factors as absorption rates and difficulty swallowing. If you’re faced with a picky eater who refuses to take supplements no matter what form they’re in, you may want to select vitamin B complex drops, which savvy parents can add to a beverage with no detection to avoid the fuss. Additionally, those who are concerned with quality ingredients may want to look for an organic vitamin B complex liquid to fulfill their needs. Overall, the variety of vitamin B complex liquid and solid supplements is endless, so you should have no trouble finding the best vitamin B complex liquid for you and your loved ones.

There are also types of B complex supplements that contain other nutrients in addition to the B vitamins, such as vitamin B complex plus C and vitamin B complex with zinc. These two options in particular may be helpful choices for anyone looking to boost immune function, as all of these micronutrients (B complex vitamins, vitamin C, and zinc) play an important role in the health of the immune system

The best time to take vitamin B complex is going to be in the morning or the middle of the afternoon. This is because many of the B vitamins, particularly B12, assist your body’s metabolism, making it easier to convert food into energy. The energy boost these vitamins provide can be extremely helpful for kickstarting your morning or helping you finish the day strong. However, it can be detrimental to your sleep schedule if your liquid vitamin B complex is taken too close to bedtime. Pay attention to when you take your supplements and try to make a habit out of it to avoid missing doses or consuming them at the wrong times and messing with your typical routine.

One of the most convenient ways to make sure your body receives enough liquid B complex vitamins along with other essential micronutrients is to start taking a multivitamin, such as Better Family’s Liquid Daily Multivitamin. Our diverse blend of nutrients includes the rest of the B complex vitamins along with vitamins A, E, D, and K, as well as important minerals like zinc, iodine, chromium, and selenium. This all-in-one liquid solution can be consumed sublingually and is more concentrated than other liquid multivitamins, making it the standout choice among competitors for fast absorption of only the highest quality micronutrients. Both safe and effective, our Liquid Daily Multivitamin is a great choice for any household and can be given to family members of all ages.

Liquid B Complex With B12 Sublingual

If you’re ever wondering “Should I take B12 or B complex?” remember that B complex supplements typically contain the RDI for all 8 B vitamins, including vitamin B12. Depending on your reason for taking the supplement, you may choose an individual sublingual B12 option over a liquid B complex with B12. For example, someone with a B12 deficiency or who is looking for a way to boost their energy during the day may want to take a B12 supplement alone. Consider your unique situation and purpose for adding the supplement before making your decision.

As we mentioned, vitamin B12 is an excellent way to give yourself enough drive to make it through the middle of the day. One of the roles that B12 plays in the body is the breaking down of foods, converting them into the glucose that powers cells. This increased metabolic function can lead to a burst of energy, with some people even electing to swap in a B12 supplement in place of their afternoon cup of coffee to combat the 2PM feeling without the need for caffeine or sugars. But sublingual liquid B complex with B12 benefits don’t just stop at energy. An assistant to healthy brain function, vitamin B12 has the ability to heighten your mood and reduce symptoms of depression. It also helps with the creation of red blood cells, an essential function that prevents the development of anemia. Those who are pregnant or nursing are often advised to take B12 supplements as well in order to encourage healthy development of the fetus and reduce the risk of major birth defects (2). 

Vitamin B Complex Benefits And Side Effects

Now that you know all about the different options available for these types of supplements, let’s take a look at some of the vitamin B complex benefits and side effects you may experience. 

Since each of the B vitamins has its own specific function in the body, it is difficult to provide a general list of B complex liquid benefits. Instead, we will focus on two B vitamins (B1 and B6) in particular and the potential they have to benefit your body’s overall health. Since its function involves converting food to energy, vitamin B1 benefits include both higher energy levels and higher moods. In fact, vitamin B1 deficiency has sometimes been linked to low moods. Maintaining the recommended amount of thiamine in your body’s system better prepares you to fight the symptoms of depression while improving brain function and minimizing the risks of heart disease as well (3).

Vitamin B6 benefits include better circulation, help with PMS, and improved brain function. As indicated by its role in facilitating normal brain development, pyridoxine has the ability to both boost your mood and your memory. Your brain needs B6 in order to produce serotonin, commonly referred to as the happy chemical, so not consuming enough of this particular B vitamin can often contribute to low moods and other symptoms of depression. Pyridoxine also helps regulate the amount of homocysteine in your body, a chemical that has been linked to dementia and Alzheimer’s disease when present in high amounts (4).

The B complex vitamins belong to the category of water-soluble vitamins. Unlike fat-soluble vitamins, they are not stored within the body’s fatty tissue and liver. Instead, excess amounts of water-soluble vitamins exit the body fairly quickly, meaning that they need to be replenished on a daily basis. For this reason, vitamin B complex side effects are quite uncommon, as overdosing on B vitamins is very difficult to do without taking an excessive amount of them. The notable signs of a B complex overdose could include excessive thirst, blurry vision, abdominal cramps, nausea, increased urination, diarrhea, and skin flushing, so seek medical attention immediately if you experience any of these symptoms (5). However, as long as you take your supplements as directed, you should not need to worry about experiencing B-complex liquid side effects.
