about this product.

P5P 50 by Pure Encapsulations delivers pyridoxal 5'-phosphate, the biologically active coenzyme form of vitamin B6. Unlike standard pyridoxine, P5P does not require hepatic conversion to become functional — it is ready for use by the body immediately. This matters for people with compromised liver function, certain genetic variants affecting B6 metabolism (including common MTHFR-adjacent polymorphisms), or those who have not responded well to standard B6 supplementation.

B6 as P5P is involved in over 100 enzymatic reactions, most notably in amino acid metabolism, the synthesis of neurotransmitters including serotonin, dopamine, and GABA, and the production of haemoglobin. It also plays a role in homocysteine regulation alongside folate and B12.

This supplement suits people with confirmed low B6 status on blood testing, those supporting mood and cognitive function under clinical guidance, women experiencing B6-responsive symptoms such as premenstrual mood changes or pregnancy-related nausea, and individuals on long-term medications known to deplete B6.

Pure Encapsulations is a practitioner-grade brand with a long-standing reputation for minimal excipient use and consistent formulation standards. The active form distinguishes this product from lower-cost pyridoxine supplements found on the high street.

frequently asked.

What is the difference between P5P and regular vitamin B6?

Standard vitamin B6 supplements typically use pyridoxine, which must be converted by the liver into P5P before the body can use it. P5P is the active coenzyme form, so it bypasses that conversion step — particularly relevant if your liver function is compromised or if you carry genetic variants that slow the conversion process.

Who would benefit most from taking P5P specifically?

People with confirmed low B6 on a blood test, those on medications known to deplete B6 (such as certain oral contraceptives or isoniazid), women with B6-responsive premenstrual symptoms, and individuals managing elevated homocysteine alongside B12 and folate are all reasonable candidates. Speak to a clinician to confirm whether this form is appropriate for you.

Is it safe to take long term?

B6 supplementation at high doses over extended periods has been associated with peripheral neuropathy, so total daily intake from all sources should be monitored. At the dose in this product, use is generally considered appropriate under standard guidance, but ongoing use is best reviewed with a healthcare practitioner.

Can I take this alongside other B-vitamin supplements or a multivitamin?

Possibly, but check the B6 content across everything you are taking. Combining multiple B6-containing products can push total daily intake above levels considered safe for long-term use. A practitioner or pharmacist can help you assess your combined intake.

How will I know if it is working?

B6 status is measurable via blood testing — plasma pyridoxal 5'-phosphate is the most direct marker. Functional improvements (mood, energy, symptom relief) vary by individual and underlying reason for deficiency. If you started supplementing in response to a confirmed deficiency, retesting after 8 to 12 weeks gives the clearest picture.

QQVerified Buyer

The first adrenal support that made a quick difference.

4 days ago

Gentle on a sensitive stomach, and I feel like myself again. I had tried two other glandulars before this and neither sat right.

MRVerified Buyer

Steadier mornings within a fortnight.

1 week ago

I was sceptical about glandulars, but my mid-afternoon crash has genuinely eased. One capsule with breakfast and I forget about it.

ALVerified Buyer

Subtle, but real.

2 weeks ago

Not a stimulant, which is exactly what I wanted. It took about ten days, then I realised I wasn’t dreading the afternoon any more.

SKVerified Buyer

My clinician recommended it.

3 weeks ago

Bought after a blood panel flagged a flat cortisol curve. Easy to take, no jitters, and the sourcing is refreshingly transparent.

TPVerified Buyer

Recovery feels faster.

1 month ago

Training hard through a stressful stretch and this has helped me bounce back between sessions. Already on my second bottle.

DVVerified Buyer

Does what it says.

1 month ago

No frills, one ingredient, a sensible dose. I appreciate that it is designed to be used for a season rather than forever.
