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!

XXX Tech by SOVRYN Dr. Brian Sovryn The crossroads between technology, sensuality, and metaphysics - and the longest running anarchist podcast in the world! Brought to you by Dr. Brian Sovryn. Al-Quran In English Dr. Soha The complete Quran translation in English, Narrated by Dr. Soha. Hosted on Acast. See acast.com/privacy for more information. NEWMORROW SESSIONS - A PodCast Series on the Future of Hospitality Mario C. Bauer, Florian Schneider, Axel Weber & Dr. Tillman Bardt The Newmorrow PodCast is more than a podcast — it's a platform for open dialog on the future of our business, a platform for those building what doesn’t exist yet. Here, we share and embrace our passion for the hospitality industry, but we won’t romanticize the journey. We ask the tough questions, confront uncomfortable truths, and prepare for a future that resists easy answers. We believe that the tougher and wilder times become, the more openly, honestly and humanely people need to talk to each other and act together. We believe, openness, togetherness, and truthfulness should also be cornerstones of a professional community to develop our utopian idea of „open source“. This is a space where visionaries don’t just imagine the future — they wrestle with the paradoxes that shape it: success vs. happiness, data vs. instinct, stability vs. reinvention. Join leaders, entrepreneurs, and thinkers as they share not what made them — but what’s actively shaping them, now and next. So tune in
