Type 1 Diabetes Mellitus
Conditions
Brief summary
This study aims to evaluate the improvement of autoimmune status in patients with Type 1 Diabetes (T1D) through supplementation with 5-Methyltetrahydrofolate, and to explore the safety and efficacy of this treatment. The research seeks to provide new methods for the treatment of T1D and offer innovative ideas for enhancing the quality of life of T1D patients.
Interventions
Daily oral intake of active folate 800ug combined with basic diabetic treatment
take oral placebo daily combined with basic diabetic treatment

Determined by the investigator to be capable and willing to: perform self-monitoring of blood glucose (SMBG); complete patient logs as required; receive diabetes education; and comply with the study treatment and visit schedule as per the protocol. 6\) Signed informed consent form, with parental/guardian consent and signature required for pediatric/adolescent participants.
Exclusion criteria
