In this podcast, I want to talk to you about vitamin A and your immune system. Now, I’ve done plenty of other videos on the role of zinc, vitamin D, and vitamin C in the immune system, but I haven’t touched on vitamin A yet.
Vitamin A is an essential part of the immune system. A vitamin A deficiency will leave your body susceptible to infections—especially in the respiratory system, including your lungs, sinuses, and throat.
You need vitamin A for your mucous membranes. In particular, vitamin A is required for the creation of mucin. Mucin is an essential part of the mucus membrane.
Vitamin A is also involved in the epithelial layer and lymphatic system layer. Each of these acts as a barrier for microbes.
When pathogens enter the body, your body triggers macrophages. These are large phagocytic cells that consume pathogens and clean up other harmful debris. Macrophages are your body’s first line of defense against infection.
Your thymus gland, which is right above the heart, helps train your immune cells. The thymus can actually activate and synthesize vitamin A.
Vitamin A is also required for dendritic cells and neutrophil traps.
When you’re low in vitamin A, your risk increases for:
• Ulcerative colitis
• MS
• Psoriasis
• Lupus
How can you get more vitamin A? The best source of vitamin A are:
• Beef
• Liver
• Cod liver oil
• Mackerel
• Salmon
• Goat cheese
• Butter
• Cream cheese
• Eggs
• Vegetables (pre-vitamin A in carotenoid form)

| 0:29.0 | Welcome to the Dr. Berg's Healthy Kito and Interminute fasting podcast, where Dr. Berg takes you on the journey for the truth about getting healthy and losing healthy weight. Now I've done quite a few videos on the immune system relating to zinc, |
| 0:47.5 | vitamin C, vitamin D, but I haven't done one on vitamin A. |
| 0:52.0 | Vitamin A is essential for your immune system. |
| 0:54.7 | Having a vitamin A deficiency will increase your susceptibility |
| 0:58.2 | to getting more infections, especially in the respiratory system, |
| 1:01.8 | both lower lungs as well as sinus and throat. |
| 1:06.3 | You need vitamin A for all of your mucous membranes. |
| 1:10.6 | And I'm talking about the sinuses, the mouth, the lungs, and even the gut. |
| 1:17.0 | With al-itemine, you're not going to be able to produce the mucous membranes that you need. |
| 1:21.0 | The mucous membranes are an important barrier to microbes. The microbes have a difficult time of penetrating this mucous layer and they get stuck in there and they can't move too well. |
| 1:30.0 | We have a lot of your immune cells sitting there waiting for some type of invasion so they can actually |
| 1:36.5 | attack and also signal the rest of the team as they hold down the fort. The internal skin of your body, the epithelial layer of your sinuses, |
| 1:46.5 | your throat, and your lungs, which basically is just beneath the mucus, is highly influenced by vitamin A. Without vitamin A you're not going to have a normal cell layer. |
| 1:58.0 | Also, vitamin A keeps these cells together so they don't leak or open up and allow microbes or pathogens to invade. |
| 2:05.0 | In your colon you have the mucous membrane and then you have a layer of colon cells and |
| 2:11.8 | then you have a layer of the lymphatic system just below that and |
| 2:15.2 | that's where a lot of immune reactions take place. If you haven't seen my video on lymph notes |
| 2:20.6 | I put a link down below. It's Vitamin A is needed to make something called |
