Sentinel Vitamin B12 is a dietary supplement containing 100 micrograms of Vitamin B12 per tablet, with 100 tablets per bottle. This essential nutrient supports red blood cell formation, DNA synthesis, and proper nervous system function while helping maintain healthy energy levels. Vitamin B12 is particularly important for vegetarians, vegans, older adults, and those with absorption issues as they may be at higher risk of deficiency. The supplement comes in an amber-colored bottle to protect the vitamin from light degradation and maintain potency. Each tablet provides 100mcg of B12, which can help prevent deficiency when taken as directed. As with any supplement, consult with a healthcare provider before starting use, especially if you have any underlying medical conditions or are taking medications.
