Vitamin A

is a fat-soluble vitamin that is also a powerful antioxidant. Vitamin A plays a critical role in maintaining healthy vision, neurological function, immune function, healthy skin, reproduction, boost bone health, promotes muscle growth, reduce risk of acne and more. Vitamin A also helps the heart, lungs, kidneys, and other organs work properly. 

You can find two types of Vit A in our product and that’s Retinyl Palmitate and Beta Carotene (Provitamin A).

Vitamin A is found in different forms. Preformed vitamin A occurs in meat, fish, and dairy produce. Provitamin A is stored in fruits, vegetables, and other plant-based products. Retinol is the predominant, active form of vitamin A found in the blood. Retinyl palmitate is the storage form of the vitamin. Beta-carotene is a precursor of vitamin A and is found in plants. This “pro-vitamin,” in itself an antioxidant, is converted into vitamin A as needed by the body, so there is no risk of overdose or toxicity. Ready-made retinol, the active form of vitamin A, only comes from animal sources. The richest sources of retinol are:

  • organ meats, such as liver
  • fatty fish, such herring and salmon, and fish oils
  • butter, milk, and cheese
  • eggs
  • pumpkin, carrots, squash and other orange-colored vegetables
  • sweet potatoes
  • orange-colored fruits, such as cantaloupes, papayas, and mangos
  • broccoli, spinach, turnip greens, and other dark, leafy green vegetables
  • zucchini
  • peppers

Plant-based foods contain carotenoids, antioxidant forms of vitamin A. These are converted to retinol in the body.

Vitamin D

is sometimes called the “Sunshine Vitamin” because it’s produced in your skin in response to sunlight. It’s a fat-soluble vitamin in a family of compounds that includes vitamins D1, D2, and D3.

Your body produces vitamin D naturally when it’s directly exposed to sunlight. You can also get it through certain foods and supplements to ensure adequate levels of the vitamin in your blood.

Vitamin D has several important functions. Perhaps the most vital are regulating the absorption of calcium and phosphorus, and facilitating normal immune system function.  Vitamin D also fights disease, reduce depression and boost weight loss. Getting a sufficient amount of vitamin D is important for normal growth and development of bones and teeth, as well as improved resistance against certain diseases.

If your body doesn’t get enough vitamin D, you’re at risk of developing bone abnormalities such as soft bones (osteomalacia) or fragile bones (osteoporosis).

Few foods contain vitamin D naturally. Because of this, some foods are fortified. This means that vitamin D has been added. Foods that contain vitamin D include:

  • salmon
  • sardines
  • egg yolk
  • shrimp
  • milk (fortified)
  • cereal (fortified)
  • yogurt (fortified)
  • orange juice (fortified)
  • broccoli, spinach, turnip greens, and other dark, leafy green vegetables
  • zucchini
  • peppers

It can be hard to get enough vitamin D each day through sun exposure and food alone, so taking vitamin D supplements can help.

Vitamin E

It took a good few weeks of research to put this product together and present to our dear customers mostly because Ryszard was key to find the best quality ingredients available on the market. We have heard so much about the powerful 4 fat soluble vitamins but we weren’t aware how important it is to have the right type of vitamins and how hard is to get them but Ryszard was digging hard and finally he got the right components to put the product together.

So all you can find in POREBSKI Liposomal ADEK is a compound of natural, the highest quality ingredients all packed in the liposomal technology to increase bioavailability.  To give you an idea why it wasn’t easy to find a natural ingredients lets meet some facts..

Vitamins A, D, E, and K are the fat soluble vitamins. In other words, they are insoluble in water and therefore are carried in the body through fats. One of the factors that make these group of vitamins handy, is that cooking does not make them less potent. The following list represents the best sources of complete, dietary Vitamin E:

Oils (Unrefind)

  • Wheat germ oil
  • Sunflower oil
  • Safflower oil
  • Corn oil
  • Soybean oil
  • Extra virgin olive oil

Vegetable and Fruit

  • Spinach
  • Broccoli
  • Asparagus
  • Kiwi
  • Mango
  • Olives

Nuts & Nut products

  • Almonds
  • Sunflower seeds
  • Hazelnuts
  • Peanut butter
  • Peanuts
  • Pecans
  • Walnuts

Vitamin E is not one thing. It is eight similar but different compounds of four tocopherols (alpha, beta, gamma, delta) and four tocotrienols (alpha, beta, gamma, delta). Both of them require fat in the diet in order to be absorbed and distributed within the body. Although it may seem like the two members are similar, various differences exist between them as outlined below. Both members of the vitamin E family act as antioxidants. These eight compounds exist naturally in your body and in a well-balanced, whole-food diet like the Mediterranean Diet.

Unfortunately, most of the attention Vitamin E has received is focused on just one of these compounds—alpha-tocopherol. The reason is alpha-tocopherol is the most easily isolated and synthesized of the eight constituents of Vitamin E—and by far the most commonly used form in supplementation.

Tocotrienols for the other hand is the most powerful group of vit E and the hardest to find. We are proud to have a natural, Red Palm fruit oil in our product, rich in Tocotrienols. Vitamin E fights against free radicals in a number of different cellular arenas. But one of its most important functions appears to be protecting your cell membranes from free radical damage. Getting All Vitamin E, eight components. In the Correct, Natural Amounts. Probably the single best way to get your Vitamin E is through food sources high in the different tocopherols and tocotrienols. These sources represent a balanced mix of the necessary Vitamin E components to give you the most antioxidant protection against free radicals. Whole grains, nuts, dark green vegetables and some fruits are generally good sources.

Vitamin K

This vitamin is the most important of all the fat soluble vitamins. The name K comes from a German word, coagulation. They are synthesised by the bacteria in our gut/throat.

It can be found in :

  • Green leafy vegetables, such as kale, spinach, turnip greens, collards, Swiss chard, mustard greens, parsley, romaine, and green leaf lettuce.
  • Vegetables such as Brussels sprouts, broccoli, cauliflower, and cabbage.
  • Fish, liver, meat, eggs, and cereals (contain smaller amounts)



The most important function of this vitamin in our body is to clot blood. It also helps in maintaining bone health to reduce the risk of osteoporosis and also in kidney metabolism.
