Product Description



At Seeking Health, we believe there is a fundamental step missing, almost 100% of the time, in today’s healthcare system. A consistent focus on treating symptoms, rather than building health, can mean that you cycle in and out of symptoms and “treatment” over and over, sometimes for years.
Our approach is to support and optimize your digestion, reduce environmental exposure and toxic burden and diet optimization so nutrients can flood in and allow our body to do what it does best - Heal.
Potent Bioavailable Vitamin B6*
P-5-P for Hormone Balance and Mood Support*
Vitamin B6 is an essential nutrient that supports numerous functions in your body. It’s needed to metabolize homocysteine, normalize mood, balance hormones, and help you sleep.*
Seeking Health’s P-5-P contains a potent 25 mg of vitamin B6 (1,471% Daily Value) in the active form of P-5-P (pyridoxal 5’-phosphate).*
- Gluten-free high-strength vitamin B6.*
- Homocysteine metabolism support.*
- May help support a healthy mood.*

Who Needs P-5-P?
P-5-P is intended for those seeking an "active" or "coenzyme" form of vitamin B6 in a potent dose. Vitamin B6 ( P-5-P) is needed for more than 140 enzyme reactions in the body, including healthy hormone balance, mood, and methylation. It also supports healthy homocysteine metabolism and healthy levels of homocysteine, which are thought to support cardiovascular health.*

Key Ingredients
- P-5-P (pyridoxal-5’-phosphate): The active, readily available coenzyme form of vitamin B6 plays a role in neurotransmitter metabolism and supporting a healthy mood. P-5-P also supports the healthy metabolism of hormones, homocysteine, sulfur, amino acids, and over 140 different enzymatic reactions in the body.*

Why Does P-5-P work?
The active form of vitamin B6, P-5-P, is used as a coenzyme in over 140 chemical reactions. These include enzymes that facilitate detoxification, neurotransmitter function, hormone metabolism and signaling, and much more.*
One of the most well-known enzymes supported by P-5-P is the CBS enzyme. This facilitates the conversion of homocysteine into cysteine that is used for making glutathione.*

How Do I Use P-5-P?
- Take 1 capsule daily with food or as directed by your healthcare provider.

What's In It?

Why Does it Work?

How do I use it?
At Seeking Health, every ingredient is carefully sourced, researched, and tested. Each meets strict specifications for manufacturing standards before any ingredient is allowed for use. We only use the highest-quality ingredients.
P-5-P is free of GMOs, Gluten, Artificial Colors, Artificial Flavors, Artificial Preservatives, Dairy, Egg, Fish, Shellfish, Tree Nuts, Peanuts, Wheat, and Soy.
Active, bioavailable form of vitamin B6.*
P-5-P plays a role in the AADC enzyme. The Aromatic Acid Decarboxylase enzyme regulates the production of both dopamine and serotonin. These are considered the “feel good” neurotransmitters that support a healthy mood.*
How to Enhance
Consider Pulsing
Dr. Ben Lynch recommends using certain supplements based on your need for them. Start with a partial serving and increase slowly over time to the full serving, only if needed. When you start feeling good, consider reducing the serving size, skipping days, or pausing supplementation. Then take again when you feel you need it (stressful day, traveling, chemical exposure, etc.), hence “pulsing.” Work with your qualified healthcare practitioner to determine what’s best for you.
Pairs Well With
Optimal Magnesium, as both P-5-P (vitamin B6) and magnesium work together to support healthy mental wellbeing and hormone balance.* SulfiteX to support sulfite breakdown. High doses of vitamin B6 may increase sulfite production by acting as a cofactor for enzymes in the glutathione pathway.* Phosphatidyl Serine, to further support a healthy response to stress.*
Clean Your Genes
Though supplements may benefit you immensely, they are only one step of your health journey. In his best-selling book, Dirty Genes, Dr. Ben Lynch describes the Clean Genes Protocol. Combining supplements with this protocol may help promote optimal epigenetic health.*

- Reviewed in the United States on June 20, 2018New research Oct 2017 study (The Vitamin B6 Paradox) on Researchgate showed that taking the pyridoxine form of b6 in larger doses actually leads to decreased vitamin b6 function and symptoms of deficiency. The inactive form pyridoxine competitively inhibits the active pyridoxal-5-phosphate form and both pyridoxal 5 phosphate dependent enzymes were inhibited by pyridoxine. So the more pyridoxine you take, the more it can work against you and even lead to deficiency B6 symptoms. It also mentions it was toxic even at lower doses killing cells, and Lareb reported that some found doses as low as 2mg/day caused the same neuropathy symptoms as higher doses.
This product is Pyrodoxal-5-phosphate, the active form which doesnt have any of those issues, and so in my opinion seems to be the better way to supplement vitamin b6 and why I chose it and now avoid pyridoxine as much as I can.
Vitamin B6 in the non active form also needs Magnesium, Zinc, and Vitamin B2 to convert to its active form. As many are low on magnesium, or are under stress which depletes both magnesium and zinc, it seems that many may not be converting Vitamin B6 as well. There are also genetic mutations MTHFR that some may have that can keep the conversion from occuring. Seeking Health is a high quality brand, and this B6 does not have many of the fillers others do. I would buy again anytime I need a standalone B6 supplement. I also use their Seeking Health B Minus which has 20mg P5P with the other B vitamins except B12 and also Folate, which can be added separate as needed.
Has my review been of help to you? If so, would you consider hitting the "helpful" button below? I'd greatly appreciate it. Thank you!
- Reviewed in the United States on May 10, 2023I need to take the P5P version of B6. I have to take a minimum of 100mg/day while going through a seizure medication change. Anxiety is a side effect of the new medication. My neurologist said to take this for 3 months. Some days I need to take a little more to make the anxiety side effect to go completely away. These work great! I plan to not stop taking these. These really help with mood. If you have anxiety issues give these a try. I was amazed how helpful they are.
- Reviewed in the United States on March 16, 2024I took another brand of P 5 P last year and the dosage was too high. As a result, I stopped taking them due to side effects. This brand offers a lower dose and from my understanding, a lower dose works more efficiently. Also, I do not have the side effects as I did in the past from too much B6.
- Reviewed in the United States on October 26, 2020I got this product as a newly diagnosed gestational diabetes patient. I’ve never had diabetes in the past, although that’s up in the air given the lack of looking into it lol
I was looking up how effective dietary changes and glucose levels are in terms of pregnancy parameters, and came across a few articles and studies suggestion that this particular strain of B6 was integral in combating gestational diabetes in particular; mostly due to the unique relationship of placental hormones and insulin that occur during a pregnancy. I already take a multivitamin but this P5P is not in there and is also not anywhere in the pharmacy vitamins sections I looked in in person.
Eager to get my act together quickly, I ordered this product here and had it next day.
I started dietary changes pretty quickly into being told I’d failed my initial screen, so it’s hard to know exactly if this product did something? I will say that my glucose numbers evened out extremely quickly. I had a fasting rate of 140 the first morning I began all my chnages. Now it is consistently between 97-103. Those are still considered “high” in pregnancy land but damn a 40 point difference? I doubt it was my diet alone as I’m still learning what even works and what doesn’t. At that point I hadn’t yet received a diet consult or any suggestions about correct diabetic eating. So I’m erring on the side of “this vitamin is working” lol.
Since then I failed my 3 hours test (but that was literally only 2 days after my initial failed screen), and have met w dietitian and log my glucoses. Today I reached 94 fasting glucose for first time since all of this started about 2 weeks ago. I still take this vitamin daily.
I don’t know what it’s doing or if it’s working but I feel like it is. Placebo effect? Maybe? Actually working? I’d like to think so. :)
- Reviewed in the United States on January 25, 2025I bought this after reading that this would help with trigger finger issues. Only had a week and will give it 30 days. As of yet no benefit
- Reviewed in the United States on August 30, 2022I always had toxic issues with B6. This active version of B6- P5P I take with no problem.
With this supplement (which I take only 1 25mg pill every other day), I have vivid dreams which I remember pretty well, and I believe (and hope) that I'm getting a deeper, higher quality sleep as well.
There are some interesting reports of reduction of anxiety, depression, and help with burning feet and a host of other possibilities with P5P
especially if you have found standard B6 to be toxic to some degree. Try this P5P. Be your own doctor and decide how much to take, how often, and for how long.
I am not one who believes more is always better. Give it a try and see if your dreams and sleep are positively affected.
After 6 months: I've cut back to 2 25mg pills a week, and may cut back more or stop for a while at least as it seems my body has enough B6 (p5p) now. No rules in all this, I just notice I'm getting good sleep and dreams with less and less p5p. Learning as I go along ... Be cautious about taking too much....
