Alarmingly, almost 40% of the people in the US are Vitamin B12 deficient, a wide majority being women. Although eating B12 rich foods certainly helps, nutritionists also encourage taking some of the best Vitamin B12 supplements daily to meet the body’s required dose.

In this article, I’ll share the most powerful Vitamin B12 supplements on sale that you can buy online on Amazon.

What is Vitamin B12?

Also known as cobalamin, Vitamin B12 is a water-soluble nutrient crucial for making DNA, proper brain health, and red blood cell production. Pregnant women also need this vitamin to prevent complications during baby development. 

Your body doesn’t produce B12 on its own. Rather you get it from different food sources. It’s essentially present in animal-derived foods such as dairy products or meat, and rarely in plants.

Some rich Vitamin B12 food sources include;

  • Tuna
  • Lobsters
  • Crabs 
  • Lamb’s liver
  • Beef 
  • Turkey meat
  • Swiss cheese
  • Mozzarella cheese
  • Eggs 
  • Milk

What Are The Signs of Vitamin B12 Deficiency?

Besides eating foods naturally loaded with this nutrient, Vitamin B12 supplements consumption is another reliable way to prevent its shortage.

If you notice any of these symptoms of Vitamin B12 deficiency, take some B12 supplements ASAP:

  • Anemia
  • Weakness and fatigue
  • Constipation
  • Loss of appetite
  • Mood swings
  • Irregular heartbeat 
  • Shortness of breath

What Causes Vitamin B12 Deficiency?

Certain factors can put you at high risk of low Vitamin B12 levels. So it’s important to stay alert and enrich your diet with the best Vitamin B12 supplements available.

Here are a few reasons why you might have low B12:

  • Plant-based diet: Vitamin B12 isn’t found in fruits and vegetables. If you’re a vegan or vegetarian, you may be at risk of being B12 deficient.
  • Old age: As you get older, your stomach produces less acid to absorb Vitamin B12. Ultimately, you’ll have severely low Vitamin B12. This need can only be fixed through powerful Vitamin B12 supplements. 
  • Pregnancy: When you’re pregnant, your body has a higher than usual demand for Vitamin B12 for brain and spinal cord development. Decreased B12 could cause serious pregnancy complications or affect your baby’s proper growth. 
  • Digestive disorders: Certain digestive problems like heartburn and Crohn’s disease mess up Vitamin B12 absorption. You might need B12 supplements to prevent its deficiency.

What are the Benefits of Vitamin B12 supplements?

Because of its important role in your body’s wellbeing, there are numerous benefits of taking Vitamin B12 supplements daily.

Here are a handful of Vitamin B12 supplements benefits for women of all ages:

  • Good bone health: Sufficient B12 can boost your bone mineral density and reduce the chances of bone diseases such as osteoporosis. 
  • Mood improvement: This vitamin produces “the happy hormone” or serotonin, responsible for regulating mood and helping with depression.
  • Energy boost: Some of the best Vitamin B12 supplements also energize your body and reduce fatigue. 
  • Memory enhancement: Vitamin B12 pills prevent loss of neurons and decrease the risk of dementia or memory loss. 
  • Anemia prevention: As B12 is essential for red blood cell development, these supplements can boost your red blood cell count to avoid anemia naturally, particularly during pregnancy.
  • Proper heart health: If you’re at risk of heart diseases like heart attack, cholesterol etc, taking Vitamin B12 supplements daily can help regulate your cardiovascular health.

Do Vitamin B12 Supplements Really Work?

The main question is whether or not these supplements actually work and if there are any side effects of Vitamin B12 pills. 

Research shows that taking Vitamin B12 supplements along with other nutrients such as folic acid can reduce the chance of heart attack and blood clot issues. 

Some scientists believe that certain pills prescribed with Vitamin B12 can treat diabetic neuropathy — a condition that wrecks blood circulation in feet because of high blood sugar.

So many medicinal combinations with Vitamin B12 supplements are beneficial for your health. But in case of severe deficiencies or serious diseases, there’s little B12 can do to help. 

If you’re on a special no-meat diet, I’d recommend consulting a nutritionist to find the right dose of B12 for your daily requirement.

Do Vitamin B12 Tablets Have Side Effects?

Most health experts agree that there are no serious life-threatening side effects of taking Vitamin B12. When taken in high doses, there are a few risks such as;

  • Rashes
  • Dizziness
  • Headaches
  • Itching
  • Swelling
  • Breathing problems

One study links super high amounts of Vitamin B12 in blood to the risk of lung cancer. Although it needs further proof, this can only happen if one indulges in a reckless B12 overdose.

Needless to say, you can safely start some of these best Vitamin B12 supplements to enjoy their ample metabolic benefits.
