Personalised Nutraceutical Treatment Guided by MTHFR Genotype in Mental Health: A Retrospective Cohort Study.
(PubMed, Nutrients)
- "In this real-world primary care cohort, personalised nutraceutical treatment, grounded in one-carbon metabolism support and applied alongside usual care, was associated with clinically meaningful reductions in psychological distress. Outcomes were comparable across MTHFR genotypes when treatments were appropriately tailored, suggesting that genotype and biomarker-informed nutraceutical strategies may mitigate potential metabolic disadvantages. These findings support further controlled research into precision nutraceutical psychiatry for anxiety and depression. Secondary analyses of genotype subgroup, specific supplements, and biomarker-outcome associations are reported alongside Benjamini-Hochberg FDR-adjusted p-values and should be interpreted as hypothesis-generating."

Case Report: Persistent isolated hyperhomocysteinemia in an adolescent with celiac disease and homozygous MTHFR c.665C>T polymorphism: a multifactorial disturbance of one-carbon metabolism.
(PubMed, Front Genet)
- "Sequential trials of pyridoxine, hydroxocobalamin, and high-dose betaine produced modest or transient improvement...Combined oral methylfolate (1,000 µg daily) and vitamin B12 (cyanocobalamin 1,000 µg daily) reduced homocysteine from 66 to 24.6 μmol/L in 8 weeks. This case illustrates multifactorial hyperhomocysteinemia arising from interactions between celiac disease-related micronutrient vulnerability and reduced MTHFR activity. Recognition of gene-nutrient interactions is important when classical metabolic disorders are excluded and may guide targeted therapy."

Sensory ataxia associated with vitamin B12 deficiency and hypocalcaemia in a patient with 'hikikomori' syndrome.
(PubMed, BMJ Case Rep)
- "Sunlight exposure combined with methylcobalamin treatment improved both neurological symptoms and serum calcium levels. Repeated measurements during 4 years of follow-up demonstrated a strong positive association between serum vitamin B12 and corrected calcium levels. This case suggests that prolonged social withdrawal and reduced sunlight exposure may contribute to concurrent vitamin D and vitamin B12 deficiencies and that resultant hypocalcaemia may contribute to vitamin B12 deficiency."

Revisiting the hematological manifestations of vitamin B12 deficiency.
(PubMed, Front Nutr)
- "Severe presentations, seen in approximately 10% of cases, include pancytopenia, hemolytic anemia, and pseudothrombotic microangiopathy, which may mimic hematological malignancies or thrombotic microangiopathies. Early recognition is crucial, as vitamin B12 replacement leads to rapid and often complete hematological recovery."

Copper(II/III) Redox Couple Enables C─H Methylation via a Radical Mechanism Analogous to SAM Enzymes.
(PubMed, Angew Chem Int Ed Engl)
- "Many enzymatic C-H methylation reactions proceed through sequential one-electron steps mediated by distinct redox cofactors, such as Fe4S4 clusters and methylcobalamin...The CuIII-CH3 complex mediates C-H methylation through hydrogen atom transfer (HAT) and methyl radical transfer, affording methylated products from substrates similar to those targeted by radical SAM methyltransferases. By merging the characteristic HAT and radical rebound reactivity within a single organometallic center, this copper(II/III)-methyl species provides a synthetic platform that mirrors key mechanistic features of enzymatic C-H methylation."

Synergistic pain relief in cervical radiculopathy: A randomized trial of topical methylcobalamin gel with phonophoresis and Mulligan mobilization.
(PubMed, Acta Neurol Belg)
- "The findings of this study suggests that efficacy of MeCbl gel application by phonophoresis in combination with Mulligan manual therapy is higher when compared with conventional MeCbl gel application and Mulligan manual therapy in the treatment of cervical radiculopathy. The improved results from the use of phonophoresis are most probably due to increased absorption of medication and its deep penetration into the tissues."

Bacopa-Enriched Formulation Enhances Memory and Synaptic Plasticity in a Rat Model of Vascular Dementia.
(PubMed, Behav Brain Res)
- "This study evaluated the effect of a Bacopa-enriched formulation (BEF) containing Bacopa monnieri, coenzyme Q10, acetyl-L-carnitine, phosphatidylserine, benfotiamine, and methyl folate in a rat 2-vessel occlusion (2VO) model of VD. Motor and exploratory functions remained largely unaffected. Findings from this study suggest BEF's memory enhancement is primarily mediated via modulation of excitatory neurotransmission, enhancement of neuroplasticity, and modification of cognitive function biomarkers, with minimal cholinergic system involvement."

Worsening Postural Orthostatic Tachycardia Syndrome Associated with Compounded Tirzepatide Use
(ENDO 2026)
- "A 47-year-old female with a history of dyslipidemia and obstructive sleep apnea presented with progressive episodes of palpitations, dizziness, diaphoresis, nausea, and near-syncope...Seven months prior to presentation, the patient began using compounded tirzepatide which contained methylcobalamin obtained from a medical spa, losing 20 pounds...Given the close temporal relationship between tirzepatide initiation and symptom progression, the absence of alternative etiologies, and improvement following discontinuation, drug-induced worsening of POTS was suspected. This case suggests a potential association between compounded tirzepatide and autonomic dysfunction, highlighting the need for clinical awareness as GLP-1RA use expands."
