  As we spoke before, 𝐕𝐢𝐭𝐚𝐦𝐢𝐧 𝐀 is 𝘧𝘢𝘵-𝘴𝘰𝘭𝘶𝘣𝘭𝘦. ⚠️We don’t eat Vit A, even in supplements. When we consume 🍎fruits, 🥕vegetables or 💊supplements, in reality, we are taking something called “𝘳𝘦𝘵𝘪𝘯𝘺𝘭 𝘦𝘴𝘵𝘦𝘳𝘴” (also known as preformed Vit A) or 𝘱𝘳𝘰𝘷𝘪𝘵𝘢𝘮𝘪𝘯 𝘈. ✅One way or another, they suffer alterations to become 𝘳𝘦𝘵𝘪𝘯𝘰𝘭𝘴. This is simply because those are easier absorbed in the small bowel. ❎As they are absorbed, small molecules called “𝐜𝐡𝐲𝐥𝐨𝐦𝐢𝐜𝐫𝐨𝐧𝐬” will transport them into the Liver. ❎If the Liver has reached its full capacity of Vitamin A, other small molecules called 𝐕𝐋𝐃𝐋 (𝘝𝘦𝘳𝘺 𝘓𝘰𝘸-𝘋𝘦𝘯𝘴𝘪𝘵𝘺 𝘓𝘪𝘱𝘰𝘱𝘳𝘰𝘵𝘦𝘪𝘯𝘴) will transport it (often already changed into retinyl palmitate) to other tissues. ✴Those tissues are mainly: 1️⃣Adipose tissue (AKA fat) 2️⃣Lungs 3️⃣Kidneys ❎Another group of molecules called 𝐋𝐃𝐋 (𝘓𝘰𝘸-𝘋𝘦𝘯𝘴𝘪𝘵𝘺 𝘓𝘪𝘱𝘰𝘱𝘳𝘰𝘵𝘦𝘪𝘯𝘴) might also do that transport. ‼️𝐕𝐞𝐫𝐲 𝐢𝐦𝐩𝐨𝐫𝐭𝐚𝐧𝐭 𝐭𝐨 𝐤𝐧𝐨𝐰: ▶️VLDL and LDL are what is called “bad cholesterol” ▶️HDL is what is called “good cholesterol” ✴Bear in mind any disease affecting the bowels (and I am referring to the 𝘴𝘮𝘢𝘭𝘭 𝘣𝘰𝘸𝘦𝘭) will affect fat absorption capacity. In turn, this will affect Vitamin A absorption as well. ❓Remember we spoke about Vit A being fat soluble? ✅Conditions that affect Vit A absorption: ➡️Cystic Fibrosis ➡️Pancreatic problems ➡️Inflammatory Bowel Disease ➡️Cholestasis (conditions preventing bile passing to the bowel, from the Liver) ➡️Small bowel bypass surgery ➡️Significant parasitic infestation ➡️Kidney problems ➡️Alcoholism ➡️Low fat in the diet ⚠️People with any of these conditions should take 𝐕𝐢𝐭 𝐀 𝐬𝐮𝐩𝐩𝐥𝐞𝐦𝐞𝐧𝐭𝐬. When Vit A is not absorbed, it will be excreted in stools. The one that becomes inactivated in the bloodstream will be excreted in the urine. ✴The big problem is that our body absorbs Vit A better than it destroys it. ⛔This can lead to excessive accumulation and 𝐕𝐢𝐭 𝐀 𝐭𝐨𝐱𝐢𝐜𝐢𝐭𝐲. www.facebook.com/permalink.php?story_fbid=151235170337036&id=100063516604410

  𝐕𝐢𝐭𝐚𝐦𝐢𝐧 𝐀 Also known as Retinol or Retinoic Acid. Those names derive from an area in the back of the eye. It was the first 𝘧𝘢𝘵-𝘴𝘰𝘭𝘶𝘣𝘭𝘦 but not the first Vitamin to be discovered. 🇪🇬It all started with the 𝘌𝘨𝘺𝘱𝘵𝘪𝘢𝘯𝘴, as they found that some types of 𝘣𝘭𝘪𝘯𝘥𝘯𝘦𝘴𝘴 could be cured by 𝘦𝘢𝘵𝘪𝘯𝘨 𝘭𝘪𝘷𝘦𝘳. 🔶️This Vitamin plays a vital role in 👁𝘷𝘪𝘴𝘪𝘰𝘯, 𝘨𝘳𝘰𝘸𝘵𝘩, 𝘤𝘦𝘭𝘭 𝘥𝘪𝘷𝘪𝘴𝘪𝘰𝘯 and 𝘪𝘯𝘵𝘦𝘨𝘳𝘪𝘵𝘺 (mainly 𝘢𝘪𝘳𝘸𝘢𝘺𝘴, 𝘶𝘳𝘪𝘯𝘢𝘳𝘺 𝘵𝘳𝘢𝘤𝘵 and 𝘨𝘶𝘵), 𝘳𝘦𝘱𝘳𝘰𝘥𝘶𝘤𝘵𝘪𝘰𝘯 and 𝘪𝘮𝘮𝘶𝘯𝘪𝘵𝘺. We cannot forget how important it is for foetal development. 🤰But beware, pregnant women DO NOT need a Vitamin A dose higher than the daily recommended dose. ✅Due to this, many believe it is 𝐭𝐡𝐞 𝐦𝐨𝐬𝐭 𝐞𝐬𝐬𝐞𝐧𝐭𝐢𝐚𝐥 𝐕𝐢𝐭𝐚𝐦𝐢𝐧 in animal life (not just humans). 🔻When there is a deficiency, it can lead to: ➡ ️Blindness ➡️Poor growth ➡️Low fertility ➡️Low immune response ➡️Dry skin and hair ➡️Broken fingernails ✴𝐍𝐨𝐭𝐞 𝐨𝐟 𝐜𝐚𝐮𝐭𝐢𝐨𝐧: If you use creams containing Vit A, do not go on long sun exposures, leading to skin cancer development! On the other hand, sun exposure decreases skin Vit A. ✳𝗪𝐡𝐚𝐭 𝐭𝐨 𝐝𝐨? Use it after sun and/or at nighttime. ❓Is there a connection between Vitamin A and allergies? 🔸️The only relationship found so far is between lack of it and increased risk of allergic asthma and allergic rhinitis (hayfever). ‼️There is a hypothesis saying that Vit A might help prevent an adverse reaction when eating different kinds of food. ⚠️𝐅𝐢𝐧𝐚𝐥 𝐧𝐨𝐭𝐞. ❌Too much Vitamin A can also lead to problems. Such as: ➡️Nausea ➡️Vomiting ➡️Vertigo ➡️Blurry vision ➡️Bone thinning ➡️Liver damage ➡️Headache ➡️Diarrhoea ➡️Nausea ➡️Skin irritation ➡️Pain in the joints and bone ➡️Birth defects www.facebook.com/permalink.php?story_fbid=145674797559740&id=100063516604410  |
