Let’s talk about vitamin A—the benefits of vitamin A and the dark side.

Vitamin A is a non-keratinizing vitamin. Keratinization is a condition that causes skin issues.

Both a vitamin A deficiency and excess vitamin A can affect the internal and external skin in many ways.

Vitamin A is involved in supporting the immune system as well. There is an association between vitamin A deficiency and autoimmune conditions like Graves’ and Hashimoto’s. Vitamin A also allows iodine to be absorbed.

Signs of vitamin A deficiency:
• Poor night vision
• Blindness
• Dry eyes
• Poor immunity
• Skin problems
• Bone issues

Signs of too much vitamin A:
• Abnormal bone formation
• Dry lips
• Dry skin
• Double vision
• Alopecia
• Oily skin
• Peeling skin
• Heart valve calcification
• Hypercalcemia
• Intracranial pressure

Vitamin A toxicity is rare, but taking a synthetic vitamin A supplement may increase your risk. Synthetic vitamin A may also increase the risk of lung cancer. Accutane, a form of synthetic vitamin A, has serious potential side effects.

I suggest getting your vitamin A from food sources or natural food-based supplements.

Foods high in vitamin A (retinol):
• Cod liver oil
• Egg yolks
• Grass-fed butter
• Grass-fed cheese
• Liver

Beta carotene is the precursor to the active form of vitamin A (retinol). Beta carotene is in foods like carrots and spinach.

But, If you’re relying on beta carotene alone to get your vitamin A or if you have a liver or gallbladder issue, you could be deficient in vitamin A.

    I’m watching this, just after I just cooked and ate liver for the first time a few hours ago. I avoided liver so long because of the fear of vitamin A toxicity. But after months of research, I found out it is safe to consume (I hope). If you just do it in very minimal amounts of just an ounce.

    I mean I’ve heard of the people who eat liver everyday and the people who eat a full pack of liver. I’m only looking to probably eat an ounce like 2-3 times a week and keep the rest in the freezer.

    But due to my damaged gut from sibo and autoimmune disorders. I know I’m lacking so much in vital nutrients and minerals. And all those symptoms I’ve been suffering with for a while, like the night vision, skin issues, peeling skin and more. Especially how my old diet was for many years prior, where I mainly ate garbage all day. Where I barely got any neccasary nutrients in my daily before.

    There have been more studies, some showing far worse 12:1 and even 21:1 conversion of beta-carotene to vitamin A. The conversion also varies drastically based on genetics (certain European genes heavily reduce it). Essentially, a decent portion of the population is incapable of ever converting enough. Without consumption of animal products, many will be deficient.

    Also, my own personal anecdote I eat primarily beef and eggs with butter, and I recently added cod liver to my diet for the omega-3(didn’t trust rancid capsules). I didn’t even realize it had SOO much vitamin A. Anyways, I noticed a week or so later that my morning and nighttime vision was significantly better. I guess dozens of eggs a week were still not enough for my needs. I’m curious why my diet wasn’t enough.

      Maybe I should go back to taking 1/2 teaspoon of cod liver oil daily.
