It's important that you're addressing your deficiencies, as both
vitamin B12 and
vitamin D are essential for your overall health. Vitamin B12 deficiency is common in vegetarians, and people with lactose intolerance can also miss out on other key nutrients found in dairy products, which might worsen the issue. Your current B12 level of 134 pg/ml is on the lower side, as the normal range is typically between 200–900 pg/ml. For vitamin D, your level of 21.8 ng/ml is also indicative of deficiency, as optimal levels should generally be between 30–100 ng/ml.
Becadexamin is a good choice as it combines both vitamins, but it's important to monitor how your body responds over time, particularly if you're using it long term. It’s advisable to regularly check your vitamin levels to ensure you're achieving the desired improvement without any side effects.
In your case, since incorporating non-vegetarian foods is not an option, continuing with a supplement that combines these essential nutrients seems reasonable. However, you may also want to explore plant-based fortified foods or consult a dietitian for a tailored plan.
