Pyridoxal 5'-phosphate (P5P), the active form of vitamin B6, has been associated with acne and facial breakouts, especially when taken in high doses. Here are some key points from various studies:

1. General Association with Acne:
   High doses of vitamin B6 and B12 have been linked to acneiform eruptions and exacerbation of existing acne¹. Supplementation with these vitamins can lead to the development of acne-like lesions on the face, chest, and back.

2. Specific Case Reports:

   • One study documented the onset or worsening of acne during treatment with high doses of vitamin B6 and B12².
   • Another report described a case where a daily high-dose B vitamin supplement, including B6, led to acne and rosacea-like eruptions, which improved upon discontinuation³.

3. Mechanism and Hypotheses:
   While the exact pathogenesis is unclear, these reactions often resolve after stopping the vitamin supplement¹².

Given these findings, it is reasonable to conclude that P5P might cause acne or facial breakouts, especially if taken in higher doses. If you experience such side effects, it's advisable to discontinue the supplement and consult a healthcare professional.

Pyridoxal 5'-phosphate (P5P) is the active form of vitamin B6. It serves as a crucial coenzyme in various biochemical reactions in the body. Here are some of the primary functions and benefits of P5P:

1. Amino Acid Metabolism: P5P is involved in the metabolism of amino acids through reactions such as transamination, deamination, and decarboxylation¹. It helps in synthesizing neurotransmitters like dopamine, serotonin, and gamma-aminobutyric acid (GABA).

2. Carbohydrate and Lipid Metabolism: It plays a role in the metabolism of carbohydrates and lipids¹. P5P helps in gluconeogenesis (the synthesis of glucose from non-carbohydrate sources) and glycogenolysis (the breakdown of glycogen to glucose).

3. Cognitive and Neurological Health: P5P is essential for maintaining brain health. It is involved in the synthesis of neurotransmitters and can influence brain function². Deficiency in vitamin B6 can lead to neurological issues such as seizures and cognitive impairments.

4. Homocysteine Regulation: P5P helps maintain normal levels of homocysteine, an amino acid in the blood. Elevated homocysteine levels are associated with cardiovascular diseases².

5. Immune Function: It supports immune function by promoting lymphocyte production and cytokine responses².

6. Hemoglobin Formation: P5P is necessary for the formation of hemoglobin, the protein in red blood cells that carries oxygen throughout the body².

7. Enzyme Co-factor: P5P serves as a cofactor for over 100 enzyme reactions, mostly related to protein metabolism².

Overall, P5P is an essential nutrient for numerous physiological processes, particularly those concerning protein metabolism, brain function, and cardiovascular health.
