Warning Signs of a Vitamin B12 Deficiency

Low or deficient levels of vitamin B12 can have various symptoms, some of which can be severe and result in irreversible damage, particularly to the nervous system and brain, warns Medical News Today. However, such cases are rare. Even slightly lower-than-normal levels of vitamin B12 can trigger nonspecific symptoms that are not sufficient for diagnosing a deficiency. The source goes on to list the following as the most common symptoms associated with a vitamin B12 deficiency…

  • Depression
  • Confusion
  • Memory problems
  • Fatigue, headaches
  • Mood changes
  • Difficulty concentrating

As the condition worsens, neurological changes like numbness and tingling in the hands and feet may occur, along with difficulty maintaining balance. If it occurs in infants, Medical News Today says a lack of vitamin B12 can cause unusual movements, such as face tremors, reflex problems, feeding difficulties, irritability, and if left untreated, potential growth problems. Vitamin B12 deficiency has also been associated with an increased risk of cognitive impairment and depression.

In severe cases, insufficient levels can lead to anemia, which is characterized by fatigue, shortness of breath, and an irregular heartbeat. Additional symptoms include a sore mouth or tongue, weight loss, pale or yellowing skin, diarrhea, and menstrual problems. It’s important to address vitamin B12 deficiencies promptly to prevent potential complications and alleviate symptoms.

Nature Made Vitamin B12 Soft Gels

Nature Made offers a budget-friendly option for vitamin B12 supplementation. Available in the form of soft gels makes for easy convenience and consumption.

Healthline highlights Nature Made’s high quality and safety standards, being both cGMP certified and USP verified. As a result, this brand is consistently recognized by pharmacists as a top choice for vitamins and supplements.

While Nature Made B12 soft gels are a popular choice, it’s important to consider a few factors. Healthline warns that the use of gelatin in the soft gels means they are not suitable for vegans, and individuals with a soy allergy should avoid this supplement due to the inclusion of soybean oil. For those who are taking them, take one per day with water and a meal.
