Pyridoxal-5’-phosphate (Active form of Vitamin B6)

What is it?

Pyridoxal-5’-phosphate (PLP) is the active form of vitamin B6, a water-soluble vitamin crucial for various bodily functions. It serves as a cofactor for numerous enzymatic reactions involved in amino acid metabolism, neurotransmitter synthesis, and glycogen breakdown.

How does it work for medicinal purposes?

As a coenzyme, PLP facilitates the conversion of amino acids, particularly tryptophan, into neurotransmitters like serotonin and dopamine. It also aids in the metabolism of homocysteine and supports the synthesis of hemoglobin, contributing to overall nervous system function and red blood cell formation.

What are the active ingredients that are important for its medicinal properties?

The active ingredient is Pyridoxal-5’-phosphate (PLP), the active form of vitamin B6.

What forms does it come in?

Pyridoxal-5’-phosphate is available in supplement form, often as capsules, tablets, or liquid formulations.

What if I have an imbalance or deficiency?

A deficiency in PLP can lead to various neurological symptoms, including neuropathy, seizures, and cognitive impairments. Supplementation is typically recommended to correct deficiencies.

When was it first used for medicinal purposes?

PLP's medicinal use dates back to the mid-20th century when its role in amino acid metabolism and neurological function was elucidated.

What it can help treat?

1. Treatment of Pyridoxine-Dependent Epilepsy (PDE): PLP supplementation effectively controls seizures in individuals with PDE.
2. Prevention and Treatment of Nausea and Vomiting During Pregnancy: PLP has been shown to alleviate nausea and vomiting symptoms in pregnant women.
3. Management of Premenstrual Syndrome (PMS): PLP supplementation may reduce symptoms of PMS, including mood swings and irritability.
4. Cognitive Function and Mental Health Support: PLP plays a crucial role in neurotransmitter synthesis, potentially benefiting cognitive function and mental health.
5. Homocysteine Regulation: PLP helps in converting homocysteine to cysteine, thus supporting cardiovascular health.
6. Aid in Metabolism of Amino Acids: PLP facilitates the metabolism of various amino acids, contributing to overall protein synthesis and energy production.
7. Treatment of Certain Skin Conditions: PLP supplementation may aid in the treatment of certain dermatological conditions, including acne and eczema.
8. Support for Individuals with Autism Spectrum Disorder (ASD): PLP supplementation may improve certain symptoms associated with ASD, such as irritability and sensory issues.
9. Management of Carpal Tunnel Syndrome (CTS): PLP supplementation has shown promising results in alleviating symptoms of CTS, such as pain and numbness.
10. Support for Individuals with Attention Deficit Hyperactivity Disorder (ADHD): PLP may play a role in neurotransmitter balance, potentially benefiting individuals with ADHD.
11. Enhances glucose tolerance, helps regulate blood glucose levels, and alleviates symptoms of neuropathy.

What can it help prevent?

1. Cardiovascular Disease: PLP aids in homocysteine metabolism, reducing the risk of cardiovascular events.
2. Neurological Disorders: Adequate PLP levels may help prevent certain neurological disorders, including epilepsy and neuropathy.
3. Premenstrual Syndrome (PMS) Symptoms: PLP supplementation may prevent the onset or reduce the severity of PMS symptoms.
4. Nausea and Vomiting During Pregnancy: Regular intake of PLP may prevent or reduce the incidence of nausea and vomiting during pregnancy.
5. Cognitive Decline: PLP supports neurotransmitter synthesis, potentially reducing the risk of cognitive decline.
6. Skin Conditions: Adequate PLP levels may help prevent certain dermatological conditions, such as acne and eczema.
7. Metabolic Disorders: PLP plays a role in amino acid metabolism, contributing to overall metabolic health.
8. Mood Disorders: PLP's involvement in neurotransmitter synthesis may help prevent mood disorders like depression and anxiety.
9. Carpal Tunnel Syndrome (CTS): Adequate PLP levels may reduce the risk of developing CTS or alleviate symptoms associated with the condition.
10. Autism Spectrum Disorder (ASD) Symptoms: Early intervention with PLP supplementation may help prevent or mitigate certain symptoms associated with ASD.

• Headaches: Reported in around 3% of cases.
• Peripheral Neuropathy: Rare but possible with prolonged high-dose supplementation.
• Photosensitivity: Sensitivity to sunlight, particularly with high doses.
• Sensory Neuropathy: Tingling or numbness, especially with long-term use at high doses.

What is the recommended daily dosage?

• Adult Men: 1.3 - 1.7 mg/day
• Adult Women: 1.3 - 1.5 mg/day

How long does it take to work:

The onset of action varies depending on the condition being treated or prevented. In some cases, improvement may be observed within days to weeks of supplementation.

When is best time to take it?

• Morning or afternoon.

Is it best to take it with or without food?

• Generally well-tolerated with or without food, but taking with a meal can aid absorption.
