Did You Know You Can Make Your Own Antibiotics, With Vitamin D?

Sometimes referred to as sunshine in a bottle, vitamin D (a hormone, in actual fact) is a powerful and essential nutrient when it comes to our wellbeing. Almost every single cell in our body contains a vitamin D receptor (VDR) which highlights just how important this UVB-induced nutrient is to our health and cellular function.[1] One of my favourite properties of vitamin D is how – in sufficient quantities – it enables us to make our own antibiotics. Our Bodies Can Make Antibiotics Yes, you read that correctly. No, this is not a drill. Our bodies are, or more specifically our immune system is, capable of producing specific and not-so-specific responses to various immunological challenges. One of the incredible features of this is, when presented with pathogenic (read disease-causing) microorganisms, we endogenously produce our own antimicrobial medication in response – called antimicrobial peptides. Antimicrobial peptides (AMPs) are an ancient arm of the human immune system and these various peptides protect us against bacteria, viruses, fungi, and even certain parasites. Virtually all human tissues and cells typically exposed to microbes are able to produce AMPs. Important AMPs belonging to two structurally distinct classes, known as the defensins and the cathelicidins, are produced by neutrophils and epithelial cells.[2] And, these are regulated by vitamin D![3,4,5,6,7] And the reason I have emphasised epithelial cells is – not only does this include skin, but all mucous membranes including the lungs as well. Very important when it comes to cold and ‘flu. Our Lungs Can Fight Off Cold + Flu I want to give a shoutout to cathelicidin LL-37 in particular as this AMP,...
