Sometimes, B12 deficiency triggers gastrointestinal symptoms, such as appetite loss, sore tongue and mouth, stomach discomfort, heartburn, nausea and even vomiting (Sobczyska-Malefora et al., 2021)

The most commonly reported adverse reactions were hypersensitivity reactions (e.g., rash, urticaria), edema-related reactions (e.g., arthralgia, extremity pain, peripheral edema, and carpal tunnel syndrome), hyperglycemia, and injection site reactions (injection site erythema, pruritus, pain, urticaria, irritation, swelling, and hemorrhage)

Clients using them as part of a broader wellness plan often find they complement a healthy diet and exercise routine more meaningfully than B12 alone
