What Is Coenzymated B-6?
Pyridoxal 5'-phosphate (P-5'-P) is the biologically active form of vitamin B6, and Source Naturals Coenzymated B-6 supplies this directly for optimal absorption. Unlike standard pyridoxine hydrochloride, which requires conversion in the liver, this active coenzyme is ready for immediate use by the body, making it particularly beneficial for those with impaired liver function or genetic variations that affect vitamin B6 metabolism.
P-5'-P is involved in over 100 enzymatic reactions, including the metabolism of amino acids, neurotransmitters, and homocysteine. By providing the ready-to-use coenzyme, this supplement supports efficient biochemical processes throughout the body.
How Does It Compare to Standard B6?
The primary advantage of P-5'-P lies in its bioavailability. Pyridoxine HCl must be converted in the liver to P-5'-P, a process that can be inefficient in some individuals due to genetic polymorphisms (e.g., in the enzyme pyridoxal kinase) or liver stress. By providing the active coenzyme directly, Coenzymated B-6 ensures that the vitamin is ready for immediate use by the body.
Additionally, P-5'-P may have a lower risk of side effects at high doses compared to pyridoxine HCl, as it may not accumulate in the same way. However, both forms are effective when used appropriately.
Key Health Benefits
Vitamin B6, as pyridoxal phosphate, contributes to several critical functions:
-
Normal psychological function: The active form plays a role in synthesising neurotransmitters such as dopamine, norepinephrine, and serotonin, which regulate mood, focus, and stress response.
-
Energy metabolism: B6 helps convert food into usable energy by aiding in the breakdown of glycogen and amino acids.
-
Homocysteine metabolism: Along with folate and B12, vitamin B6 helps maintain normal homocysteine levels, supporting cardiovascular health.
-
Normal red blood cell formation: B6 contributes to the production of haemoglobin and red blood cells.
While these benefits are well-documented, individual results may vary. Consistent use as part of a balanced diet is recommended.
Dosage Guidance
Each tablet of Source Naturals Coenzymated B-6 provides 333 mg of pyridoxal 5'-phosphate. This is significantly higher than the Nutrient Reference Value (NRV) for adults (1.4 mg) and exceeds the safe upper level of 100 mg per day for pyridoxine. However, the active form P-5'-P has a different molecular weight and absorption profile, so direct comparisons are not straightforward. Due to the high potency, we advise consulting a health care professional before use, especially if you are pregnant, nursing, or taking medications.
For most people, lower doses (25–100 mg) are sufficient for general wellness. The 333 mg strength is often chosen by those with specific needs under medical supervision.

Safety Information
Vitamin B6 is water-soluble, meaning excess is generally excreted in urine. However, prolonged intake of very high doses (above 100 mg per day) has been associated with peripheral neuropathy (nerve damage), which may be reversible upon discontinuation. Symptoms include numbness, tingling, and balance difficulties. To minimise risk, do not exceed the recommended serving size and consult a health care provider before combining with other B6 supplements.
Drug interactions are possible with certain medications, including levodopa (for Parkinson’s disease), anticonvulsants, and some antibiotics. Always inform your health care professional about all supplements you take.
Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle. Always read the label and follow the directions for use.
