Although synthetic antidiabetic drugs are available, the side effects and limited long-term effectiveness of these medications highlight the urgent need for safer, more potent alternative therapies. <i>Ginkgo biloba</i> L., a traditional medicinal plant rich in flavonoids, terpenoids, and bilobalide, has attracted attention for its potential role in diabetes management. This review critically evaluates the antidiabetic potential of <i>G. biloba</i> by analyzing evidence from <i>in vitro</i>, <i>in vivo</i>, and clinical studies. Moreover, this review highlights the pharmacological actions of <i>G. biloba</i> and its key bioactive compounds, focusing on their mechanisms of action, including the activation of adenosine monophosphate-activated protein kinase (AMPK), the translocation of glucose transporter type 4 (GLUT4), and the inhibition of protein tyrosine phosphatases. The review also discusses the therapeutic implications of <i>G. biloba</i> supplementation and identifies gaps in clinical validation, optimal dosing, and safety profiling. Preclinical studies have demonstrated that <i>G. biloba</i> improves glycemic control by enhancing glucose uptake, regulating insulin secretion, inhibiting α-glucosidase activity, and exerting antioxidant and anti-inflammatory effects. Additionally, clinical trials suggest that supplementation with <i>G. biloba</i> can reduce oxidative stress, improve lipid profiles, and mitigate diabetes-related complications. However, despite these promising outcomes, inconsistencies remain in present study designs, dosages, and patient populations, which question the validity of results. Furthermore, studies related to the antidiabetic effect and underlying mechanisms of <i>G. biloba</i>, such as modulation of AMPK pathways and GLUT4 expression, also remain inadequate and warrant further systematic investigation. <i>G. biloba</i> may still be considered a complementary treatment approach in managing diabetes due to its broad pharmacological activities and favorable safety profile. However, well-designed, large-scale clinical trials are crucial for establishing standardized dosing regimens, confirming long-term safety, and fully elucidating the mechanisms of action.

This review examines the mechanistic contributions of this complex at the cellular level, including any roles in mitochondrial bioenergetics, redox balance, gene regulation, and cellular repair mechanisms. Niacinamide, as a precursor to NAD⁺, enhances mitochondrial efficiency and facilitates energy production, supporting tissue regeneration. Pyridoxine functions as a cofactor in neurotransmitter biosynthesis and amino acid metabolism, contributing to nerve recovery post-surgery. Furthermore, cobalamin is crucial for maintaining the myelin sheath and facilitating axonal repair, thereby ensuring neuronal integrity and minimizing nerve damage. Additionally, pantothenic acid, through its role in coenzyme A synthesis, regulates fatty acid metabolism and accelerates cellular repair, aiding in wound healing. Biotin is fundamental for keratin synthesis and follicular cell proliferation, promoting skin integrity and hair regeneration, which are vital in aesthetic and reconstructive treatments. Meanwhile, thiamine ensures a sufficient energy supply for neuronal recovery and cellular resilience through modulating carbohydrate metabolism. Thus, by integrating these cellular mechanisms, the vitamin B complex enhances tissue repair, minimizes inflammation, and improves both aesthetic and functional outcomes.

Notably, no laboratory test exists to identify mothers at higher risk of having a child who will later be diagnosed with ASD or to identify at-risk infants before the manifestation of symptoms. One frequently described risk factor for neurodevelopmental disorders is vitamin B12 and folate deficiency, which results in macrocytic anemias.</p><p><strong>Methods: </strong>We evaluated whether increased mean corpuscular volume (MCV), an indicator of macrocytic anemias in the mother or child, is associated with increased odds of a subsequent ASD diagnosis. Maternal mean MCV (mMCV) was calculated from any value in the year before birth, and the mMCV for the child was calculated from any MCV value from birth until the end of the follow-up time. Odds ratios with 95% confidence intervals were estimated from logistic regression models.</p><p><strong>Results: </strong>A total of 3798 mothers (984 cases-ASD/2814 controls) and 9633 children (3206 cases-ASD/6427 controls) had at least one MCV value. The mMCV for the mother one year before birth was not associated with a later diagnosis of ASD in their children. In children, compared to the reference group (mMCV 76 femtoliters (fL)), an mMCV of 81 fL, 84 fL, and 91 fL was increased odds of ASD of 26%, 38%, and 32%, respectively.</p><p><strong>Conclusion: </strong>The MCV can be a potential inexpensive biomarker to identify a subset of children at risk of ASD or other developmental disorders; this exploratory study can inform larger studies to determine the clinical utility of MCV.</p>","PeriodicalId":13884,"journal":{"name":"International Journal for Vitamin and Nutrition Research","volume":"95 3","pages":"26726"},"PeriodicalIF":2.0,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144560098","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
