Product Description
Vitamin B6 is a required cofactor for hemoglobin production, the protein your red blood cells use to carry oxygen, a role that's easy to overlook next to B6's more commonly cited effects on mood and energy. Standard vitamin B6 (pyridoxine) has to be converted to its active form, pyridoxal 5'-phosphate, before your body can use it for that or anything else, and that conversion happens in the liver.
Thorne's Pyridoxal 5'-Phosphate delivers 33.8mg of the already-active form per capsule, promoting energy production and neurotransmitter synthesis.
Supports your oxygen-carrying capacity – B6 is a cofactor for hemoglobin synthesis, tying it directly to how well your blood carries oxygen during training.
Already active, no liver conversion required – This matters most if your body's conversion capacity is compromised, whether from liver function, genetics, or high overall demand.
Supports neurotransmitter production and amino acid metabolism – B6 is required for synthesizing dopamine, serotonin, and GABA, and for breaking down and using the amino acids your training relies on.
Vitamin B6 in its active form works as a cofactor for the enzymes that drive amino acid metabolism, neurotransmitter synthesis, and the breakdown of homocysteine into taurine and cysteine, a pathway relevant to cardiovascular health. It also plays a role in producing intrinsic factor and building the myelin sheath that insulates nerve cells for proper signal conduction. Some people convert standard pyridoxine to this active form less efficiently than others, whether from liver function, genetic variation, or simply high demand, which is where supplementing the pre-converted form directly makes a difference.
How to Use Thorne Pyridoxal 5'-Phosphate
Dose: Take one capsule one to three times daily, preferably with food if you're sensitive to it, or as recommended by your health-care practitioner.
Note: Check your total B6 intake before adding this on top, since it delivers a concentrated single dose rather than a balanced complex.
