2,500 mcg of Vitamin B12 for Fast Energy in Quick Dissolving Tablets


One of the most common early signs of a Vitamin B12 deficiency is fatigue or a lack of energy. The good news is that if you are deficient in B12, increasing your intake has been shown to improve your energy levels!

If you do not get enough B12 in your diet, you can add a quality B12 supplement to get adequate amounts of this critical nutrient. Not all B12 supplements are created equally. Many are filled with additives and chemicals you don’t need. Active B12 by Celarity has been formulated to deliver the finest quality ingredients so that you can tell a difference in how you feel when you take it. Say goodbye to fatigue and hello to a natural energy booster in the form of quick-dissolving Active B12 tablets.

What is ACTIVE B12?
Active B12 combines two forms of b12—adenosylcobalamin and hydroxocobalamin— to yield 2,500 mcg of B12. This quick-dissolve, natural, fruit punch-flavored tablet is formulated to support healthy energy levels, nervous system and cellular function.

Active B12 quick-dissolve tablets are free of soy, gluten, wheat, dairy, artificial sweeteners, and other irritants. Active B12 is a highly bioavailable form of cobalamin, or B12. 


  • Helps Improve Energy Levels
  • Healthy Functioning Nerves
  • Production of Red Blood Cells
  • Critical for Healthy DNA


If you have found yourself having fatigue, shortness of breath, or dizziness, you may have a B12 deficiency. There are other common signs such as vision problems and skin tingling, but luckily, it’s not hard to get the B12 you need. If you do not get enough B12 in your diet, you can add a quality B12 supplement to get adequate amounts of this critical nutrient.

Some people lack a protein called Intrinsic Factor that helps them break down B12 so it can be utilized by the body. You may also have a pH imbalance in the gut or take medications that interfere with the absorption of B12. Gastrointestinal issues can also lead to B12 deficiency. Additional symptoms include:

  • Weakness & Fatigue
  • Racing Heart
  • Mood (irritability, depression, anxiety, etc.)
  • Visual disturbances
  • Swollen tongue
  • Feeling of Pins and Needles


B12, also known as cobalamin, is an essential nutrient our bodies need, but are unable to produce. We must get this crucial vitamin from foods or supplements. It plays a role in cell production and proper levels of this nutrient help maintain healthy hair, nails, and skin.

Unfortunately, the Standard American Diet leaves many of us deficient. Some of us cannot break it down from the foods we consume. Sadly, today we consume a lot of processed foods and don’t get enough B12 from the foods we eat.

If you have a B12 deficiency you may suffer from excess anxiety and depression. Getting B12 back into your system can relieve those symptoms.

The benefits of B12 are astronomical. Not only does it support normal nerve cell function, but it is also essential for forming red blood cells. B12 has also been shown to improve mood and symptoms of depression. One of the biggest reasons many people take it is for its proven ability to increase energy levels.

With our busy lifestyles, many of us find ourselves incredibly run down and tired all the time. A lot of us are under chronic stress, which can lead to a B12 deficiency. Active B12 is a fantastic way to get your energy levels up to par!

There are many reasons you may be vitamin b12 deficient.  These reasons include:

  • Inability to break it down from food.
  • Lacking intrinsic factor in the gut
  • Gut inflammation or gastrointestinal conditions
  • Ph imbalances in the gut
  • Certain medications
  • Vegetarian diets
  • Chronic stress
  • Processed food
  • Age 


Active B12 by Celarity provides adenosylcobalamin and hydroxocobalamin acetate, both highly bioavailable forms of B12, for the support of a healthy nervous system and healthy cellular function in individuals who have been recommended to supplement with vitamin B12.

B12 is also praised in the research to have a positive impact on boosting your energy levels.  In the past it was thought that an injection of B12 was superior, but we have learned that is not case. Now you can get the B12 you need in a supplement you can take at home every day. 

Active B12 offers the formulation necessary to support a healthy nervous system and healthy cellular function. It’s a great way to help your body have natural sustained energy, without consuming artificial additives you do not want. Our quick-dissolve, fruit punch flavored tablet is an effortless way to incorporate quality B12 into your diet.
