Spotting B12 Deficiency: Essential Signs Seniors Should Know
The importance of a balanced diet cannot be overstated. It’s not just about keeping cardiovascular disease and weight gain at bay, but also about ensuring that your body gets all the essential vitamins and minerals it needs to function optimally. One of these essential vitamins is vitamin B—especially B12, which is commonly found in meat, fish, seafood, eggs, and dairy. However, it’s not uncommon to fall short of your recommended intake.
According to Samantha Turner, MPH, RDN, a registered dietitian and owner of Forks and Grace, “Vitamin B12 deficiency is relatively common, especially among older adults, vegetarians, and vegans.” She further explains that “[Vitamin B12] plays an important role in supporting nerve and brain health and energy metabolism, and is crucial for nerve development, DNA synthesis, and red blood cell formation.”
While a doctor’s visit can reveal a deficiency, there are other warning signs to be aware of. Here are some signs that you might not be getting enough vitamin B12, as per doctors and nutritionists.
Feeling constantly tired, rundown, or low on energy can be a symptom of various health problems, but it can also indicate a deficiency of this vital nutrient. Leann Poston, MD, a licensed physician and health advisor for Invigor Medical, explains, “Vitamin B12 is essential to make healthy red blood cells. Low B12 levels can decrease red blood cell production and make it difficult for them to deliver oxygen to body cells, which can cause fatigue.”
If you’re planning on conceiving, a lack of vitamin B12 could become a problem. Qianzhi Jiang, PhD, RDN, a family dietitian and owner of The Nutrition Changer, shares, “Vitamin B12 deficiency has been linked to infertility as vitamin B12 improves the number of healthy eggs and embryo quality.” She adds that a low level of vitamin B12 is also associated with increased homocysteine, an amino acid that can increase the risks of many diseases when in excess. “Elevated homocysteine levels can damage the lining of the uterus, causing infertility,” Jiang explains.
Experiencing a pins-and-needles sensation in your extremities could be a sign that your body is low on vitamin B12. Poston elaborates, “Vitamin B12 deficiencies can cause changes in how your nerves send messages throughout your body. As the rate at which nerve impulses decreases, your body interprets this with numbness and tingling.”
But that’s not all. Jiang adds, “People with vitamin B12 deficiency can experience irritability, abnormal gait, an impaired sense of smell, and absences of neurologic reflexes such as the knee-jerk reaction.” In severe cases, psychiatric symptoms that resemble the symptoms of dementia can also occur.
If you notice some tenderness in your mouth that’s not related to a burn or toothache, it could be a sign you’re lacking in vitamin B12. Poston explains, “Vitamin B12 deficiency can cause glossitis. This appears as a smooth appearance of the tongue that can be painful.”
A vitamin B12 deficiency can also lead to misshapen red blood cells, says Poston. “These cells get caught in the spleen, decreasing the number of red blood cells circulating. This condition, called anemia, can cause pale skin color.”
However, there are also internal signs of this condition. Jiang notes, “Some people may see no or very mild symptoms caused by pernicious anemia for years while others may experience fatigue, muscle weakness, or palpitations (which is a feeling that your heart is pounding or skipping a beat). However, pernicious anemia may not be seen in cases of mild vitamin B12 deficiency.”

This Fruit Tops the Charts: CDC Highlights Their Health Benefits
You might not think of adding tomatoes to your morning smoothie or yogurt parfait, but incorporating them into your lunch and dinner could be one of the best health decisions you make. The Centers for Disease Control and Prevention (CDC) recently named tomatoes the healthiest fruit in the world.
Yes, you read that right—fruit. By definition, a fruit is anything with seeds, and tomatoes fit the bill. The CDC released a list of “powerhouse” fruits and vegetables, defined as those “most strongly associated with reduced chronic disease risk.”
Interestingly, the first 26 items on this list are vegetables, primarily cruciferous or leafy greens. The first fruit to make an appearance? Tomatoes, with an impressive nutrient density score of 20.37.
The nutrient density score is a measure of the bioavailability of 17 key nutrients. For reference, the Cleveland Clinic provides a breakdown of what a medium-sized raw tomato offers:
A medium-sized raw tomato contains 17 grams of vitamin C, which accounts for 19% of the daily value (DV) recommended for adults.
In comparison, the top-ranking produce on the CDC’s “powerhouse” list is watercress, boasting a nutrient density score of 100. Following tomatoes with their score of 20.37 are several other fruits, but none come close to the nutrient-packed punch that tomatoes deliver.
Incorporating tomatoes into your meals can be a simple yet effective way to boost your nutrient intake. Whether in salads, sauces, or even as a snack, tomatoes offer a versatile and delicious option for enhancing your diet.
So next time you’re planning your meals, remember to include this powerhouse fruit. Your body will thank you for it.

Are You Eating Too Much Fiber? Doctors Reveal 5 Warning Signs
Incorporating fiber-rich foods into your diet is essential for maintaining good health. Fiber supports gastrointestinal health, regulates blood sugar levels, and lowers the risk of cardiovascular diseases. However, it’s possible to consume too much fiber, leading to several unwanted side effects. Here are five signs that you might be overdoing it with fiber, according to doctors.
Bloating and Gas
Bloating and gas are among the most common issues associated with excessive fiber intake.
“As fiber is fermented by the gut microbiota, it releases gas and other compounds, which can be bothersome,” explains Jennie Stanford, MD, an obesity medicine physician.
Different types of fiber may affect people differently. Generally, soluble fiber (found in oats) is better tolerated than insoluble fiber (found in vegetables).
Abdominal Pain and Cramping
Too much fiber can lead to abdominal pain and cramping. This happens because the digestive system struggles to process large amounts of fiber.
“While fiber is typically recommended for regular bowel movements, excessive consumption may have the opposite effect, causing constipation or diarrhea,” says Melissa Snover, RD, a registered nutritionist.
Diarrhea or Constipation
Another gastrointestinal symptom to be aware of is either diarrhea or constipation.
“Diarrhea may occur with a high fiber intake, usually as a result of drawing more water into the stool and it moving through the intestines more quickly. In other people, constipation may occur as a result of the bulk that fiber adds to stool,” Stanford explains.
Nutritional Deficiencies
Eating too much fiber can interfere with your body’s ability to absorb essential nutrients, leading to deficiencies.
“Fiber can bind to essential nutrients like calcium, iron, and zinc, preventing them from being absorbed by your body,” Snover says.
This issue can also contribute to dehydration, making adequate hydration even more critical.
Dehydration
Fiber absorbs water, which means that a high-fiber diet requires you to drink more fluids. Without proper hydration, you may experience dehydration.
“This ensures you get all the benefits of fiber without the downsides that can be caused by excessive consumption,” Snover advises.
Pay attention to these signs to ensure you’re not overloading on fiber. While fiber is vital for good health, balance is key to avoiding these uncomfortable and potentially harmful side effects.

Doctors Recommend These 9 Supplements to Help Ease Anxiety
Anxiety can be a challenging condition to manage, and while traditional treatments like medication and therapy are commonly recommended, many people are exploring supplements as a complementary option. It’s essential to consult with your healthcare provider before starting any new supplement regimen. Here are nine supplements that doctors say may help soothe anxiety symptoms.
Vitamin D
A deficiency in vitamin D has been linked to increased symptoms of anxiety and depression. Dr. Indhira Ghyssaert emphasizes the importance of this vitamin for maintaining energy levels.
“Of course, the sun is the best source of vitamin D. However, we recommend adults take a supplement to make up for the loss during winter months or in colder, darker climates,” she tells Best Life.
Consider a dose of 2000 IU, but consult your doctor for personalized advice.
Magnesium
Magnesium plays a crucial role in brain health by modulating the brain’s stress response. According to the Cleveland Clinic, it helps lower cortisol levels and balance neurotransmitters responsible for the “fight or flight” response.
“Magnesium is essential for brain health,” says Ghyssaert.
She recommends starting with 100 milligrams before bedtime and gradually increasing to 250 milligrams.
GABA
Gamma-aminobutyric acid (GABA) is a neurotransmitter that helps inhibit excessive neuronal activity, promoting calmness and reducing anxiety.
“I recommend starting with a dosage of 250 milligrams daily and working up to 750 milligrams,” Ghyssaert advises.
However, GABA is not suitable for everyone, especially those with depression or on blood pressure-lowering medications.
Vitamin B12
Vitamin B12 is essential for brain health and neural protection. Janine Bowring, ND, highlights its importance.
“From a whole food source, it has been found that vitamin B12 helps with your neural protection for your myelin. Myelin is the coating on the outside of your nerves, and a deficiency has been linked to depression,” she explained in a recent TikTok post.
Valerian Root
Valerian root is often used to improve sleep quality and reduce anxiety.
“Valerian root increases GABA levels in the brain slowly and helps to reduce anxiety and improve sleep quality,” says Ghyssaert.
She recommends starting with 300 milligrams before bedtime and working up to 600 milligrams. Avoid if you are pregnant, breastfeeding, or have liver conditions.
Creatine
Commonly known for its muscle-building benefits, creatine can also help ease anxiety symptoms. Jenna Stangland, RD, explains its impact on brain health.
“There is a relationship between creatine metabolism in the brain and depression. When there are smaller amounts of white matter creatine and phosphocreatine in the brain, more severe depressive episodes occur,” she tells Best Life.
Daily creatine supplementation can enhance brain energy levels and positively impact mood, memory, cognition, and emotion.
Fish Oil
Rich in Omega-3 fatty acids, fish oil can be beneficial for reducing anxiety. A 2018 meta-analysis published in JAMA Network Open reviewed 19 studies and found that 2,000 milligrams of Omega-3 fatty acids per day significantly reduced anxiety symptoms.
Ashwagandha
Ashwagandha is an adaptogen that helps the body manage stress. It has been shown to reduce cortisol levels and improve symptoms of anxiety and depression. Start with a lower dose and consult your doctor for the best regimen.
Lavender
Lavender supplements, often in the form of capsules or essential oils, can have calming effects. Studies have shown that lavender can reduce anxiety levels and improve sleep quality. It’s generally safe but should be used under the guidance of a healthcare provider.
These nine supplements offer a range of options for those looking to manage anxiety naturally. Always consult with your healthcare provider to determine the best course of action for your specific needs.
