By Alpro Pharmacy

SHARE:
When it comes to dietary supplements, Vitamin B6 often plays a behind-the-scenes role. Yet its benefits are powerful—from boosting your energy to protecting your nerves. But is it really safe to take daily?
Let’s explore this important nutrient through a pharmacist’s lens.
💊 What Is Vitamin B6 and Why Is It Important?
Vitamin B6 (pyridoxine) is a water-soluble vitamin that supports:
🧠 Brain health
🧬 Nerve function
🔄 Metabolism and enzyme activity
The recommended daily intake for an average adult in Malaysia is about 1.3–1.7mg.
🔍 Did You Know?
A Malaysian study found that 98% of elderly individuals are not meeting their Vitamin B6 requirement—indicating widespread deficiency.

⚠️ Can Too Much Vitamin B6 Be Harmful?
Generally, Vitamin B6 from food or supplements (10mg or less) is considered safe for long-term use.
But in certain medical cases, higher doses are prescribed under a doctor’s supervision:
Diabetic nerve pain (neuropathy): Up to 200mg/day for 3 months may be prescribed to reduce nerve discomfort.
Tuberculosis patients on isoniazid: Often require B6 to prevent nerve damage caused by the medication.
️⚠️ These high doses should never be self-prescribed.
❓ When Should You Be Concerned?
According to current evidence, Vitamin B6 is safe for long-term use if kept under 50–100mg per day.
However, extra caution is advised if:
You have kidney issues (B6 is excreted via the kidneys)
You take multiple supplements that may unknowingly increase your B6 intake
