10 Vitamins You Should NEVER Take

from Dr. Eric Berg DC · host Dr.Berg

Find out about the harmful vitamins and supplements lurking in your medicine cabinet. These dangerous vitamins are not beneficial to your health, and often have the opposite effect. Do not take these vitamins! Watch this episode next: Reset Your Body in 5 Days (With Zero Food) 0:00 Introduction: The 10 vitamins you should never take 0:40 Synthetic vitamin A 2:00 Synthetic beta carotene 3:08 Folic acid 4:25 Synthetic B12 5:51 Calcium carbonate 7:14 Iron 8:36 Magnesium oxide 9:33 Synthetic vitamin D (D2) 10:42 Omega-6 fat (Linoleic acid) 11:36 Copper Synthetic vitamins are often cheap and create a huge profit margin for the manufacturer. Most big vitamin companies are owned by Big Pharma and big chemical companies. Never take synthetic vitamin A! It can build up in the liver and fat cells and even cause a birth defect if it occurs during pregnancy. Synthetic vitamin A can also interfere with vitamin D and K2, increasing the risk of fractures. Beta carotene is not the same as vitamin A's active form. Synthetic beta carotene, made from coal tar and petroleum, can increase the risk of certain cancers. Folic acid is different from folate, the natural form of vitamin B9. Around 30% to 40% of the world's population has an alteration of the MTHFR gene, which interferes with their ability to turn folic acid into folate, causing it to build up in the blood. This can lead to an increased risk of cancer and a suppressed immune system. Synthetic B12, or cyanocobalamine, requires glutathione to convert to the active form methylcobalamine. Consuming large amounts of synthetic B12 depletes you of this vital antioxidant. Calcium carbonate is the main ingredient in many popular multivitamins. It can build up in the arteries and kidneys and increase your risk of a heart attack. Too much iron can increase your risk of type 2 diabetes, liver issues, Parkinson’s, and Alzheimer’s. Many iron supplements contain ferrous sulfate, a damaging, poor-quality source of iron. Magnesium oxide is a cheap, poorly-absorbed form of magnesium that frequently causes diarrhea. Choose magnesium glycinate for significantly better absorption, better sleep, lower cortisol, and more overall benefits. Synthetic vitamin D is called ergocalciferol and is made by exposing fungus or yeast to UV radiation. Vitamin D2 is not nearly as beneficial as vitamin D3, yet it’s the most prescribed. Don’t consume supplements with added omega-6 fat, often in the form of linoleic acid. Too much omega-6 fat increases inflammation. We need copper, but high amounts of cheap copper can be toxic. Ensure you consume copper with other trace minerals in the proper ratios, especially zinc!

You should not make any change in your health regimen or diet before first consulting a physician and obtaining a medical exam, diagnosis, and recommendation. Always seek the advice of a physician or other qualified health provider with any questions you may have regarding a medical condition. #health #keto #ketodiet #weightloss #ketolifestyle #intermittentfasting #lowcarb Thanks for watching!

Lynne's Podcast Lynne August MD Dr. A offers her interpretations and applications of Dr. Revici’s profound research at DrRevici.com and the Revici Journal. Dr. Revici was arguably fifty to one hundred years ahead of his time in his application of quantum physics to medical sciences. As a once-aspiring physicist, this alone propelled Dr. A to Dr. Revici. As a physician, she felt compelled, and in some palpable way responsible, to understand Dr. Revici’s ability to control pain and achieve remissions in terminal cancer patients with his non-toxic “guided chemotherapy”, even many cancers that conventional therapy failed to control. Most of the time his questions and solutions were as unprecedented as they were effective. While Dr. Revici was primarily focused on cancer, Dr. A’s research and therapeutics to prevent and treat all chronic and degenerative disease can transform 21st century medicine.
