Condiciones de salud que Tiamina (vitamina B1) puede ayudar a apoyar.
Thiamine deficiency has a documented gastrointestinal presentation that includes abdominal pain, distension, nausea, and altered motility. Thiamine's role in enteric nervous system function and cholinergic signaling in the gut underpins this relationship. Thiamine supplementation has been shown to resolve GI symptoms in deficient patients.
Alcohol use disorder is the primary risk factor for thiamine deficiency, and Wernicke-Korsakoff syndrome—a direct consequence of alcohol-related thiamine depletion—is a well-established neurological complication. Thiamine supplementation is standard of care in alcohol use disorder management to prevent and treat encephalopathy. The bidirectional relationship between chronic alcohol use and thiamine depletion is extensively documented.
Thiamine has direct antioxidant properties and supports antioxidant defense by promoting glutathione production and maintaining the NADPH-generating pentose phosphate pathway via transketolase. Deficiency accelerates oxidative stress, mitochondrial dysfunction, and tissue damage.
Clinical trials have tested thiamine supplementation in anxiety-related conditions, with some positive signals. A triple-blind RCT in women with polycystic ovary syndrome found 300 mg/day of thiamine for four weeks reduced anxiety and somatic symptoms. Systematic reviews of B vitamins for anxiety show mixed, modest effects, and results depend heavily on baseline deficiency status.
Thiamine is an essential cofactor in glucose metabolism, and people with diabetes frequently show lower thiamine status due to accelerated renal excretion. Clinical trials suggest high-dose thiamine supplementation may reduce markers of diabetic complications and help protect endothelial function in hyperglycemic patients. A Cochrane review identified a potential link between thiamine and lower albuminuria in diabetic kidney disease.
Thiamine is critical for brain energy production, and even mild deficiency impairs the mitochondrial ATP generation that the brain requires for cognitive clarity. Clinically, thiamine deficiency is a recognized and reversible cause of cognitive impairment, confusion, and mental dullness. Prompt thiamine repletion in deficient individuals consistently resolves these symptoms.
Thiamine concentrations in breast milk are directly dependent on maternal thiamine intake and status. Infants breastfed by thiamine-deficient mothers are at risk for infantile beriberi. Maternal supplementation corrects low breast-milk thiamine levels in deficient women, with thiamine classified as compatible with breastfeeding by WHO and the American Academy of Pediatrics.
Thiamine (vitamin B1) deficiency is documented in celiac disease patients on long-term gluten-free diet, identified in a 2019 PMC systematic review of micronutrient deficiencies in CeD patients with good GFD compliance. Whole grains, excluded in GFD, are a primary dietary source of thiamine; gluten-free cereal products are often less thiamine-fortified. Supplementation is included in clinical guidance for CeD nutritional management.
Thiamine (Vitamin B1) is an essential cofactor for pyruvate dehydrogenase and alpha-ketoglutarate dehydrogenase, the key enzymes coupling glycolysis to the TCA cycle and enabling mitochondrial ATP production from glucose. Deficiency causes profound cellular energy failure (beriberi, Wernicke's encephalopathy).
Vitamin B1 (thiamin) is essential for energy metabolism and neurological function, with an IOM-established RDA for all pediatric age groups.

Thiamine-dependent enzyme activity is reduced in Alzheimer's disease brains, and thiamine deficiency in animal models recapitulates core AD pathology including tau hyperphosphorylation and amyloid deposition. A 12-month benfotiamine RCT in mild AD slowed cognitive decline significantly. A cross-sectional study found a J-shaped association between dietary thiamine intake and cognitive performance in older adults.
Randomized controlled trials have examined thiamine as adjuvant therapy in major depressive disorder, with some evidence of accelerated symptom reduction. A 12-week double-blind RCT in MDD patients receiving SSRIs found adjuvant thiamine significantly improved depressive symptoms at six weeks. Cross-sectional data show higher rates of suboptimal thiamine status among depressed individuals.
Vitamin B1 (thiamine) is an essential cofactor in energy metabolism, required for pyruvate dehydrogenase and alpha-ketoglutarate dehydrogenase—key enzymes converting carbohydrates to ATP via the citric acid cycle. Deficiency causes fatigue and impaired physical performance; European regulatory authorities have authorized a health claim that B1 contributes to normal energy-yielding metabolism.
Thiamine deficiency is a documented cause of impaired concentration and mental fatigue, recognized as characteristic symptoms even at sub-clinical insufficiency levels. The brain's dependence on thiamine-mediated ATP production means that even modest depletion disrupts the metabolic substrate for sustained attention.
Thiamine (vitamin B1) is an essential cofactor for key energy metabolism enzymes (pyruvate dehydrogenase, α-ketoglutarate dehydrogenase, transketolase) whose activity declines in aging and neurodegenerative conditions. Low thiamine is associated with cognitive decline, cardiovascular dysfunction, and mitochondrial impairment, all hallmarks of aging.
Vitamin B1 (thiamine) is essential for carbohydrate metabolism and energy production, serving as a coenzyme in the citric acid cycle and pentose phosphate pathway. It is required for normal growth, nerve function, and metabolic development in children. Severe deficiency causes beriberi, which in infants manifests as cardiac failure and neurological dysfunction, halting normal development.
Thiamine deficiency is a direct, well-documented cause of heart failure (wet beriberi), and cardiac function dramatically improves with thiamine repletion. Even sub-clinical thiamine insufficiency is associated with increased risk of heart failure in outpatient cardiology populations. Clinical trials have assessed thiamine supplementation in chronic heart failure.
Thiamine deficiency-induced cardiac beriberi causes characteristic tachycardia as part of high-output heart failure, and thiamine repletion restores normal heart rate. Thiamine supports autonomic nervous system function and myocardial energy metabolism that underpin normal cardiac rhythm.
Vitamin B1 (thiamine) is essential for glucose metabolism in the brain and synthesis of acetylcholine and GABA. Deficiency causes severe cognitive impairment (Wernicke-Korsakoff syndrome). Supplementation in deficient populations significantly restores cognitive function; it is included in evidence-based cognitive nutrition formulations.
Thiamine deficiency is the established cause of Wernicke-Korsakoff syndrome, a severe amnesia disorder, making B1 one of the best-documented nutrients for memory function. Preclinical models show thiamine deficiency drives AD-like memory deficits, and a pilot RCT with benfotiamine in early Alzheimer's disease demonstrated slowing of cognitive decline.
One large RCT (n=556) found vitamin B1 (thiamine, 100 mg/day) significantly more effective than placebo for primary dysmenorrhea pain, and a 2014 double-blind RCT (n=240) confirmed it reduced both intensity and duration of dysmenorrhea pain. A systematic review of micronutrients for dysmenorrhea included vitamin B1 among effective interventions. It has been recommended in integrative medicine protocols.
Vitamin B1 (thiamine) is essential for brain energy metabolism and neurological function. Thiamine deficiency results in severe cognitive impairment and fatigue; adequate intake supports mental energy and alertness, and this role is recognized by EU authorized health claims.
Thiamine deficiency is linked to the progressive atherosclerosis commonly observed in metabolic syndrome, and clinical trials show thiamine supplementation improves endothelial function and blood pressure in hyperglycemic patients. Thiamine's role in glucose metabolism and oxidative stress reduction is mechanistically central to metabolic syndrome pathophysiology.
Vitamin B1 (thiamine) is a scientifically established, essential cofactor in energy metabolism. Its active form, thiamine diphosphate (TDP/TPP), is required by key enzymes—pyruvate dehydrogenase, α-ketoglutarate dehydrogenase, and transketolase—that govern carbohydrate, amino acid, and fatty acid catabolism. The NIH Office of Dietary Supplements confirms it 'plays a critical role in energy metabolism and, therefore, in the growth, development, and function of cells.' Thiamine deficiency directly impairs these pathways, causing pyruvate and lactate accumulation, reduced ATP production, and multisystem metabolic dysfunction.
Thiamine (vitamin B1) is converted to thiamine pyrophosphate (TPP), the essential cofactor for the pyruvate dehydrogenase complex (PDC) and alpha-ketoglutarate dehydrogenase (KGDH)—two critical mitochondrial enzyme complexes linking glycolysis to the TCA cycle and ETC. Thiamine deficiency directly causes mitochondrial dysfunction and is corrected in metabolic disease protocols.
Muscle cramps and pain are recognized clinical features of thiamine deficiency, linked to impaired cellular energy metabolism and metabolic acidosis in muscle tissue. Thiamine is essential for normal skeletal and cardiac muscle function.
Gastrointestinal beriberi—thiamine deficiency primarily affecting the digestive system—presents with nausea, vomiting, and abdominal pain that resolves with thiamine repletion. Thiamine supplementation has been shown to improve nausea and GI motility disorders. FDA-approved parenteral thiamine is indicated in patients who cannot take oral supplementation due to severe nausea and vomiting.
Vitamin B1 (thiamine) is an essential neurotropic vitamin required as a cofactor in glucose metabolism that indirectly supports synthesis of neurotransmitters, myelin, and nucleic acids in the nervous system. Deficiency causes severe neurological disorders including Wernicke's encephalopathy and peripheral neuropathy.
Thiamine (vitamin B1) is a critical cofactor in carbohydrate metabolism and ATP production in neurons; its deficiency causes beriberi and Wernicke's encephalopathy, both characterized by severe peripheral nerve degeneration. Vitamin B1 is classified as a neurotropic vitamin alongside B6 and B12, with evidence supporting its role in nerve cell metabolism and myelin formation. A 2025 PMC study demonstrated that B1/B6/B12 combinations enhance neural cell maturation and connectivity superior to single B vitamins.
Thiamine is directly required for the synthesis of acetylcholine, modulates GABA and glutamate levels, and has inhibitory activity against acetylcholinesterase. Deficiency causes measurable disruptions in acetylcholine, GABA, glutamate, aspartate, and serotonin levels across neuronal tissues.
Thiamin (vitamin B1) is identified as deficient in some picky-eating children, particularly those with selective eating associated with neurodevelopmental conditions. Clinical ONS trials for picky eaters include thiamin as part of the supplementation formula, with documented improvements in thiamin adequacy.
Vitamin B1 (thiamine) has been associated with improved mood and reduced anxiety in PMS, and appeared in the PMSoff combination supplement that showed significant PMS symptom reduction in a 2025 double-blind RCT. Observational data also link higher thiamine intake with lower PMS risk. Thiamine is also listed among nutritional supplements reported effective for dysmenorrhea.
Thiamine (vitamin B1) is a critical cofactor for mitochondrial energy metabolism (pyruvate dehydrogenase, α-ketoglutarate dehydrogenase complexes) that is rapidly depleted during critical illness. Thiamine deficiency is common in post-illness states and directly impairs energy recovery, cardiac function, and neurological function.
Thiamine (Vitamin B1) is a critical coenzyme in mitochondrial energy metabolism, with deficiency linked to fatigue, neurological impairment, and dysautonomia—symptoms common in post-viral fatigue. Studies have found high-dose thiamine resolves post-viral fatigue in individual cases, and EFSA recognizes B1 for energy metabolism and neurological function.
Thiamine (vitamin B1) is essential for carbohydrate metabolism and neural development, with blood levels declining during pregnancy. An international expert Delphi consensus panel (PMC 11744953, 2025, n=35 experts) listed thiamine among micronutrients important during pregnancy. Deficiency in pregnancy can cause Wernicke's encephalopathy and is associated with fetal cardiac and neurological abnormalities; it is especially critical in women with hyperemesis gravidarum.
Thiamine (vitamin B1) is an essential coenzyme for energy metabolism in hair follicle cells and is included in European combination hair loss treatments alongside L-cystine and pantothenic acid.
