Why Your Vitamins Are Not Working

DR. ERIC BERG
About this episode

You may be wondering, do I need to take vitamins? Your body needs around 180 nutrients, and it’s often difficult to satisfy these requirements, especially for vitamin D, magnesium, zinc, and vitamin B3. You can not always identify nutrient deficiencies in the blood.


Low stomach acid interferes with vitamin and mineral absorption. If you have low stomach acid, you might also experience problems breaking down food with vitamin B12. Indigestion, heartburn, and SIBO are common symptoms of low stomach acid.


Synthetic vitamins aren't the same as natural ones. Do not take synthetic vitamin B12 or B9! Some nutrients need other nutrients to function properly, so taking them in isolated forms rather than a complex can cause problems.


Many vitamins contain fillers like maltodextrin that compete for nutrients such as vitamin C. Vitamin B1 is essential for breaking down sugar and carbs, so when you consume maltodextrin, it’s easy to become deficient.


Poor diet could be a reason why vitamins aren’t working for you. If you’re diabetic, prediabetic, or have insulin resistance, vitamin absorption will be greatly inhibited. Fix this by going on a low-carb diet.


Poor-quality supplements often contain calcium carbonate, which is limestone! Multivitamins with calcium and magnesium are poorly absorbed because these two minerals compete for absorption.


Vitamin effectiveness is greatly influenced by dosage. The RDA for vitamin D3 is only 600 IU, but you need around 10,000 IU daily. If you have a chronic illness, you need therapeutic doses of vitamins, not small amounts.


Always pay attention to the milligram dosage when choosing a supplement! Taking too little of a supplement significantly reduces vitamin absorption and effectiveness.
