Vitamin Basics & Tips


Vitamin B-12 plays a critical role in energy production by aiding red blood cell formation and oxygen transport. Its deficiency can lead to fatigue and weakened immunity, making supplementation valuable for those with dietary restrictions or absorption issues. While daily recommendations vary (2.4 mcg for adults), some studies suggest higher doses may benefit specific populations, such as vegans or older adults.


Beyond energy, B-12 supports neurological health and DNA synthesis. Interestingly, its impact on hair quality stems from improved oxygen delivery to follicles. Pairing B-12 with other B vitamins (like Biotin) often enhances results, as they work synergistically. Natural sources include animal products like fish and eggs, but fortified foods or supplements help meet needs for plant-based diets.


Regular monitoring of B-12 levels is advisable, as excess supplementation is rare but imbalances can mask other deficiencies. Always consult healthcare providers for personalized dosing.
