Do you feel like Mom or Dad is starting to show signs of “losing it”? Perhaps they’re struggling more than normal with basic tasks, experiencing memory slips, or unable to think clearly. And while you’d probably dismiss it as normal aging, the truth is, there could be something else at play that’s worth digging into. We want to shed some light on a much more nuanced explanation, and no, it’s not simply a case of mental health deterioration. It might be their blood sugar. Yes, the same issues that induce diabetes are one of the leading causes of dementia in the U.S.
In this blog, we dive into the association of blood sugar and dementia and the often unsuspecting culprit– Vitamin B12 deficiency. If your loved ones are taking Metformin or similar medications for diabetes, continue reading. This knowledge may be the solution to maintaining their health, energy, and even memory!

The Link Between Blood Sugar and Dementia: Why 80% of Individuals With Dementia Have Diabetes
Are you aware that cases of dementia, 4 out of 5 cases of dementia in the U.S. have an underlying connection to blood sugar? This statistic might seem astonishing, but it becomes more logical knowing how elevated blood sugar performs in the brain. Over time, uncontrolled blood sugar can wreak havoc on blood vessels and nerves and damage those that sustain the brain. This can result in cognitive decline, memory loss, and, ultimately, dementia.
The core problem is that those who suffer from blood sugar issues, especially type 2 diabetes, find themselves in a never-ending loop of taking medications like Metformin, which do nothing to address the underlying issues– unhealthy lifestyle choices, a lack of exercise, and poor diet.
Why Metformin Isn't The Best Choice: A Risk You Didn't Anticipate
One of the primary medications used for managing excessive blood sugar levels is Metformin because it helps the body move sugar into the cells to reduce the sugar level within the blood. But after continued use for over a year, Metformin can induce some surprising side effects, which remain unknown to many people and even physicians– B12 deficiency.
Why is this important? Vitamin B12 is essential for brain development, nerve activity, and energy levels. A deficiency can lead to symptoms like:
- Overall fatigue, weakness, and lethargy
- Feeling dizzy or lightheaded (more so when standing)
- Prickling sensations or numbness in hands or feet
- Weakness in muscles or decreased reflex actions
- Concentration issues, memory problems, and brain fog
The scariest part? A B12 deficiency can imitate the signs of dementia, which makes it hard to detect, leading to misdiagnosis or being ignored altogether.
Why Standard Labs Miss B12 Deficiency
Here’s the kicker: Many people with B12 deficiencies go undetected even when regular blood tests are conducted. Most standard labs do not check for B12 because they don’t always look for indirect markers that could be causing a problem. So even if your doctor says your lab results are normal, you can still be B12 deficient and suffering from its effects.
This is particularly worrisome for older people using Metformin for an extended period. If you have a parent or grandparent who has been on this medication for several years and struggles with memory, fatigue, or other symptoms, the answer could lie in checking their B12 levels.
The Solution: Methylated B12 Supplements to the Rescue
So, if you or someone you know takes Metformin and is deficient in B12, what can you do about it? Taking the right type of B12 supplement can help greatly. With that said, not all B12 supplements are made the same. We recommend using a methylated form of B12 called methylcobalamin rather than the standard form cyanocobalamin. Why does it matter? Cyanocobalamin has a cyanide molecule in it (yes, you read it right), that some people have a genetic predisposition that can’t process it. On the other hand, methylcobalamin is a more bioavailable form of B12 that’s easier for your body to utilize effectively.
How to Supplement with B12:
- Look for a methylcobalamin supplement, not cyanocobalamin (See Dr. Autoimmune’s Methyl Power formula).
- Consult with a health professional to establish the right dosage.
- Pair Vitamin B12 with other nutrients like folate to increase absorption.
Once a B12 deficiency is addressed, many people experience significant improvements in focus, memory, and, most importantly, energy. This one simple step can make a huge difference in your quality of life!
Takeaway: Advocate for You & Your Loved Ones’ Health
Don’t disregard it if you or a relative are on Metformin and dealing with memory problems, fatigue, or brain fog. These symptoms could be a case of B12 deficiency and shouldn’t be brushed off as “aging” or “losing one’s mind”.
Start by requesting your doctor check your B12 levels. (Receiving “normal” lab results is unacceptable if symptoms remain.) Also, when adding B12 supplements, make sure it’s the best form– methylcobalamin.
You should also take additional steps to control blood sugar and slow cognitive decline, from exercising regularly to eating a more nutritious diet and targeted supplementation. Don’t assume dementia is a part of aging because it’s not. With these tools, you can help yourself or your loved ones protect their health and independence for as long as possible.
Final Thought: Micro Actions, Macro Outcomes
Small but effective makes all the difference. Whether it’s supplements, a chat with a physician, or even motivating a loved one towards healthy habits, everyone deserves to feel healthy. You might just save a life by addressing blood sugar levels and nutrient deficiencies. Reach out to our functional medicine doctors today to learn more about blood sugar and dementia!
