Support Healthy Blood Sugar—Why Vitamin B6 Matters

Support Healthy Blood Sugar—Why Vitamin B6 Matters
Dr. Kiera Emery, PharmD/MBA

Keeping your blood sugar stable is key to feeling your best—but there’s one essential nutrient most people overlook: Vitamin B6. This powerhouse vitamin plays a major role in metabolism, insulin sensitivity, and glucose control. Getting enough can make a real difference in how your body processes sugar, keeps energy steady, and supports overall health. Let’s break down why B6 matters and how to make sure you’re getting what you need.

The Role of Vitamin B6 in Blood Sugar Health

Vitamin B6, also known as pyridoxine, is a key player in metabolism, helping your body convert food into energy. It’s involved in over 100 enzyme reactions, many of which directly impact how your body processes protein and stabilizes blood sugar levels. When your metabolism is running smoothly, you’re less likely to deal with energy crashes, blood sugar spikes, or intense cravings.

But B6 doesn’t just work behind the scenes in metabolism—it also plays a major role in neurotransmitter production. It helps create serotonin and norepinephrine, two brain chemicals that regulate mood, appetite, and energy levels. When these are out of balance, you might find yourself irritable, drained, or craving sugar constantly—all signs your blood sugar isn’t where it should be.

If you’re not getting enough B6, it can throw off your blood sugar control, making it harder to feel energized and in balance.

Vitamin B6 and Insulin Sensitivity

If you have diabetes, insulin resistance, or blood sugar issues, your insulin function is everything. Your cells need to respond properly to insulin so they can absorb glucose for energy—otherwise, blood sugar stays too high. That’s where Vitamin B6 comes in.

Research suggests that low B6 levels are linked to poor insulin sensitivity, making it harder for your body to regulate blood sugar. In fact, a B6 deficiency may contribute to higher blood sugar levels and an increased risk of metabolic disorders like diabetes.

But B6’s benefits don’t stop there. It also helps produce hemoglobin, the protein that carries oxygen in your blood. When your cells are getting enough oxygen, your metabolism runs more efficiently, and your body can use glucose for energy the way it’s supposed to.

If your insulin function isn’t where it should be, B6 might be the missing link to better blood sugar control. A well-balanced supplement—like Dr. Emery’s Blood Sugar Support—can help fill the gaps where diet alone falls short.

How Vitamin B6 Deficiency Affects Blood Sugar Control

Not getting enough Vitamin B6? Your body will let you know. Low B6 levels have been linked to blood sugar imbalances, sluggish metabolism, and poor glucose tolerance—all of which can make it harder to maintain steady energy levels.

Here are some common warning signs of a B6 deficiency:

  • Fatigue and irritability – Feeling drained and moody for no clear reason.
  • Increased sugar cravings – Your body struggles to regulate blood sugar, making you reach for quick fixes.
  • Brain fog and poor concentration – Trouble focusing? Low B6 can affect neurotransmitters that impact mental clarity.
  • Weak immune function – B6 helps your immune system stay strong, and a deficiency can leave you more vulnerable to illness.

But the biggest concern? Long-term B6 deficiency has been linked to diabetic neuropathy—nerve damage caused by high blood sugar. However, too much B6 from supplements (especially in high doses over time) can also lead to nerve issues like tingling or numbness.

The key? Getting enough B6—without overdoing it—can help protect your nerves, balance blood sugar, and support long-term metabolic health.

The Best Food Sources of Vitamin B6

The easiest way to get Vitamin B6? Your diet. Here are some of the best sources:

  • Poultry – Chicken, turkey
  • Fish – Salmon, tuna
  • Starchy Veggies – Potatoes, squash
  • Fruits – Bananas, non-citrus fruits
  • Whole Grains & Fortified Cereals – Many are enriched with B6

While real food is always the best source, modern diets and medications can create nutrient gaps. That’s where targeted supplementation can make all the difference.

The Benefits of Vitamin B6 Supplements for Blood Sugar Health

When my husband was put on metformin, he started feeling drained, foggy, and exhausted. I knew it wasn’t just him—it was the nutrient depletion caused by his medication. But when I looked for a supplement to help, there was nothing on the market that truly addressed the problem. So, I formulated Dr. Emery’s Blood Sugar Support to do exactly that.

This supplement is designed to combat nutrient depletion and support blood sugar balance with the right blend of vitamins and minerals, including optimal levels of Vitamin B6 to help with:

  • Glucose metabolism – Helps your body process sugar for energy.
  • Insulin sensitivity – Plays a role in blood sugar regulation.
  • Nerve health – Supports healthy nerve function, but balance is key.
  • Energy levels – Helps support energy production, especially in cases of deficiency.

Try it risk-free for 45 days—because feeling your best is worth it.

Understanding Vitamin B6 Dosage and Side Effects

Vitamin B6 is essential for overall health, but like anything, too much or too little can cause issues. For most adults, the recommended daily intake ranges from 1.3 to 2.0 mg per day, depending on age, sex, and health conditions. Some people, especially those with metabolic disorders or nutrient depletion from medications, may benefit from higher doses—but only under medical supervision.

While B6 is crucial for blood sugar balance, nerve health, and energy production, taking too much from supplements (especially over 100 mg per day for long periods) can cause nerve-related side effects like tingling, numbness, or even nerve damage. Some people may also experience digestive discomfort, nausea, or an upset stomach if they take high doses at once.

The key to safe supplementation is balance. Getting enough B6 can support your health, but more isn’t always better. Sticking to the recommended dosage and checking with a healthcare provider when increasing intake ensures you get the benefits without the risks.

Conclusion: Take Charge of Your Blood Sugar Health

Vitamin B6 is essential for metabolism, insulin function, and overall health. Getting enough through food and supplements can help support steady energy, reduce cravings, and keep glucose levels in check. Small, consistent changes add up—and your health is worth it.
