Vitamin B6/Nutrient Depletion:- Amino acidsAmino acids: In humans, vitamin B6 decreased plasma levels of the amino acids tyrosine and methionine during endurance exercise (92).
- AntiasthmaticsAntiasthmatics: Theophylline, a prescription drug used to help manage asthma, has been shown to lower pyridoxine levels (59; 60).
- AntibioticsAntibiotics: According to secondary sources, destruction of gastrointestinal flora may reduce the production of vitamin B6.
- CycloserineCycloserine: Cycloserine, an antibiotic prescribed for tuberculosis, may affect the metabolism of pyridoxine (73).
- FurosemideFurosemide: In humans, furosemide increased urinary excretion of vitamin B6 (74).
- GlucoseGlucose: In human research, 100mg of pyridoxine daily improved glucose metabolism in gestational diabetes (28; 29).
- Hormonal agentsHormonal agents: The need for vitamin B6 supplementation in women taking birth control pills has not been proven, although some studies show decreased pyridoxine levels in these women (78).
- HydrazinesHydrazines: Pyridoxal-5-phosphate plasma concentrations were depressed in children receiving tuberculosis chemotherapy including isoniazid (81). Based on a case report, pyridoxine is suggested following isoniazid overdose (82). Hydralazine (Apresoline®) can increase pyridoxine requirements (83). Phenelzine can increase pyridoxine requirements (84).
- LipidsLipids: In humans, vitamin B6 decreased plasma levels of free fatty acids during endurance exercise (92).
- Penicillamine (Cuprimine®, Depen®)Penicillamine (Cuprimine®, Depen®): According to secondary sources, penicillamine may reduce plasma levels of vitamin B6.
