Source Naturals Vitamin B-6 500 mg, 100 Tablets

Why Choose a High-Potency Vitamin B6 Supplement?

Many people turn to vitamin B6 for its role in hormone regulation, mood support, and energy metabolism. Source Naturals Vitamin B-6 provides 500 mg of pyridoxine hydrochloride per tablet—a potent dose intended for short-term or medically supervised use. This water-soluble vitamin is essential for converting food into usable energy, supporting the nervous system, and maintaining healthy red blood cells.*

If your healthcare provider has recommended high-dose B6, this supplement offers a convenient, reliable option manufactured in the USA under strict quality standards.

What Is Vitamin B6?

Vitamin B6, also called pyridoxine, is an essential nutrient that helps your body metabolise proteins, fats, and carbohydrates. It also assists in the synthesis of hemoglobin and supports normal growth and function of red blood cells. As a water-soluble vitamin, it must be obtained through diet or supplementation.

Source Naturals Vitamin B-6 delivers 500 mg per tablet in the well-studied pyridoxine HCl form.

How to Choose a Vitamin B6 Supplement

When selecting a B6 supplement, consider the form, dosage, and manufacturing quality. Pyridoxine hydrochloride is the most common and cost-effective form. For individuals who have difficulty converting pyridoxine to its active form, pyridoxal-5-phosphate (P5P) may be an alternative. Source Naturals uses pyridoxine HCl in a simple tablet.

Look for products made in GMP-compliant facilities. Source Naturals has been trusted for over 40 years, manufacturing in Scotts Valley, California. This product is non-GMO, vegan, and gluten-free, suitable for many dietary preferences. Always review the label for specific attributes.

Recommended Dosage

The recommended dietary allowance (RDA) for vitamin B6 for most adults is 1.3–2.0 mg per day. Source Naturals Vitamin B-6 provides 500 mg per tablet—a level that exceeds the tolerable upper intake level of 100 mg per day. Therefore, this product is intended for short-term use under the direction of a healthcare practitioner. The suggested use is one tablet daily with food to reduce the risk of stomach upset. Do not exceed the recommended dose without medical advice.

Long-term use of doses above 100 mg may lead to nerve toxicity. Consult your healthcare provider if you have questions about appropriate dosing.

Potential Side Effects & Safety

Vitamin B6 is generally safe when used as directed. However, high doses (typically above 200 mg daily over extended periods) can cause neurological symptoms like numbness, tingling, and difficulty walking. These effects are usually reversible upon discontinuation. Individuals taking medications for Parkinson's disease, epilepsy, or other conditions should consult a healthcare professional before use.

If you are pregnant, nursing, or have a medical condition, seek medical advice before taking this product. Discontinue use and consult a doctor if any adverse reactions occur. Keep out of reach of children.

Frequently Asked Questions

Is 500 mg of vitamin B6 safe?

The tolerable upper intake level is 100 mg per day. A 500 mg dose greatly exceeds that, so it is not recommended for long-term use without medical supervision. Speak with your healthcare provider to determine if this dosage is appropriate for your needs.

What is the difference between pyridoxine and P5P?

Pyridoxine hydrochloride is the common supplementary form. Pyridoxal-5-phosphate (P5P) is the active coenzyme form that does not require liver conversion. Some individuals with liver issues may benefit from P5P, but pyridoxine HCl is effective for most people.

Can I take this on an empty stomach?

It is best taken with food to minimize the risk of stomach upset.
