TPIN (pineal )

Vitamin B₆ in its active form
• Helps in tissue formation
• Helps the body metabolize carbohydrates, fats and proteins
• Helps to prevent vitamin B₆ deficiency
• Provides 20 mg of vitamin B₆ per daily dose

TPIN is a source of vitamin B₆ in the form of pyridoxal-5-phosphate (PLP). As the most biologically active form of the vitamin, PLP helps to catalyze over 140 reactions.¹ Vitamin B₆ participates in nearly all metabolic reactions involving amino acids, including their synthesis and breakdown.¹ Approximately 70-80% of vitamin B₆ is present in muscle, where it acts as a coenzyme for glycogen phosphorylase.¹ This enzyme is necessary for glycogenolysis, which breaks down glycogen into glucose and provides fuel to muscle during exercise.¹ Low levels of vitamin B₆ also lead to increased synovial fluid between joints, which results in nerve compression.² Eleuthero root is a thorny shrub native to Siberia and northern parts of China, and its beneficial health effects arise from the high levels of lignans in its roots.³ TPIN also contains an extract from Ginkgo biloba, an ancient plant traditionally used in Chinese medicine.⁴ Ginkgo contains flavonoids, terpenoids and proanthocyanidins, which are responsible for its positive health effects.⁴
