When is the Best Time to Take Vitamin B12?

Vitamin B12, also called cobalamin, is one of the eight vitamins in the B-complex group. It helps in some metabolic functions of the body, such as keeping the neurological system healthy.

Vitamin B12 is also essential for synthesizing proteins like enzymes and the production of red blood cells.

Since your body cannot make vitamin B12, it is important to take food or supplements to fulfill your nutritional needs. Deficiency of the nutrient can result in problems with balance, weakness, anemia, and tingling in the hands.

Vitamin B12 is a water-soluble vitamin, which means it requires water to absorb it. Therefore, taking vitamin B12 with a glass of water on an empty stomach is recommended for maximum absorption. And the right time to do it is in the morning.

Your body cannot fully absorb the vitamins if you don’t consume them in the right manner. This blog will tell you when to take vitamin B12, allowing your body to get the most of it. Read on.

Should you take vitamin B12 in the morning or night?

The best time to take vitamin B12 is after you wake up in the morning with a glass of water. Since vitamin B12 helps boost your energy and metabolism, taking the vitamin in the morning will give you energy for the day.

Additionally, since B vitamins help stimulate your nervous system, you should take vitamin B12 in the morning or early afternoon.

Taking vitamin B12 at night is not preferable since it can affect your ability to sleep. Since metabolic processes such as digestion also slow down while sleeping, vitamin B12 will not benefit you the most.

What’s the best time to take vitamin B12 liquid?

The best time to take vitamin B12 liquid is the morning after waking up. Taking the product at night can affect your sleep.

Many people now prefer vitamin B12 as compared to tablets or injections because it is easy to consume. Just like most other vitamins, the best time to consume vitamin B12 is also early in the day on an empty stomach or with breakfast.

In this way, you have extra energy for the day. If you take coffee or tea in the morning, you should wait at least an hour after consuming caffeine to take your supplements. Caffeine can affect the absorption of minerals and vitamins.

There are various products in the market that you can get to fulfill your nutritional requirements. We recommend the Why Not Natural B12 dietary supplement, particularly because of its quality. The organic vitamin B12 liquid is known for boosting energy, mood, and memory while supporting the metabolism, immunity, and nervous system.

When is the best time to take vitamin B12 sublingual?

The right time to take vitamin B12 sublingual is in the morning on an empty stomach. By placing the vitamin under the tongue, the acidic environment improves the rate of absorption.

When the nutrient is placed under the tongue, it bypasses the digestive juice, as well as the filtration system of the liver, and enters the bloodstream directly. In this way, vitamin B12 sublingual is far more effective and fast than taking your vitamins orally. This method may also be helpful for people with a condition known as pernicious anemia.

Patients suffering from this condition don’t have enough intrinsic factor, the protein that is essential for absorbing vitamin B12. This protein is produced by the cells lining the stomach and is extremely important for the absorption of vitamin B12. Therefore, patients with pernicious anemia can benefit from taking vitamin B12 sublingually.

The right time to take vitamin B12 sublingually to combat pernicious anemia is morning on an empty stomach.

The best time to take vitamin B12 injection

Doctors recommend taking vitamin B12 injection before 6:00 pm, preferable in the morning or early afternoon. Getting your vitamin B12 shot too late in the day or evening can result in insomnia and even vivid dreams.

Vitamin B12 injections are the quickest way for your body to absorb this nutrient. Your body might only require 48 to 72 hours to make new blood cells.

Individuals who are on a vegan diet, or with atrophic gastritis and pernicious anemia, or have undergone gastrointestinal surgery can benefit the most from a

vitamin B12 injection.

It is preferable to take this injection earlier in the day before the evening, as it can provide extra energy to function through the day and prevent insomnia.

If you are also on certain medications like birth control pills, it is preferable to take vitamin B12 injections instead of pills to prevent side effects on your body’s metabolism.

Although the injection taken in the day is known for stimulating a healthier and much deeper sleep in the night, it is important to take the shot at the right time to make the most out of it.

What’s the best time to take vitamin B12 tablets?

Take vitamin B12 tablets right after you wake up to gain the most benefits from them. Taking the tablets even in the afternoon might affect your sleep later on.

It is preferable to take vitamin B12 tablets, usually with a meal, such as a good breakfast. Vitamin B12 tablets work best when you allow the tablet to melt in your mouth before swallowing. So place it under your tongue and let it melt in the acidic environment for maximum absorption.

However, make sure you are not chugging a lot of medicines together, as your body’s metabolic functions, especially digestion, might be severely affected.

The best time to take vitamin B12 for energy

Since you need energy from the beginning of the day to function effectively, you should take vitamin B12 early in the morning. Avoid drinking caffeine right before or after consuming the vitamin, as it can affect your metabolism.

Vitamin B12 helps to convert the fat and proteins in the food you eat into glucose. Your body cells get energy from glucose. However, the energy boost from vitamin B12 is not instantaneous. The vitamin could take 48 hours to form new cells. So, you should take your supplements regularly for the best results.

When is the best time to take vitamin B12 for weight loss?

Vitamin B12 plays a major role in helping your body lose weight. Take vitamin B12 in the morning on an empty stomach or with a nutritional meal for maximum benefits.

Your body depends upon various vitamins to maintain optimal health and vitamin B12 is not an exception. If you're aiming to lose weight, vitamin B12 can provide you with the needed energy for a healthy workout.

Your body also requires a healthy circulatory and respiratory system during aerobic exercise, which you can maintain by taking the right amount of B12 at the right time.


The best time to take vitamin B12 is right after you wake up in the morning. It is not preferable to consume it at night when the metabolism is slower. Since the vitamin is essential for forming red blood cells, maintaining your neurological system, and other metabolic functions, it will help if you take your B12 vitamins regularly.
