Vitamins D3, B12, and Omega-3 are essential.

The human body utilizes many nutrients: vitamins, minerals, enzymes, antioxidants, electrolytes, and more; it is tough to track them all regularly. At the same time, vitamin D3, B12, and omega-3 significantly affect our immune system. Despite the temptation to take supplements, one should always prefer consuming natural foods and controlled exposure to the sun over supplements.

Vitamin D is a cholesterol derivative; its importance for the immune and hormonal system has been known for many years.

It is advisable to incorporate controlled sun exposure with natural foods containing vitamin D3 to prevent vitamin D3 deficiency.

I prefer natural foods rich in vitamin D over supplements. The absorption of additives is inferior to that of natural foods.

• Vitamin D3 absorption is much better when eating natural, unprocessed foods than artificial supplements. Many products, such as milk, receive vitamin D supplements. Fortified vitamin D products are often processed foods! (Not recommended)
• Some supplements contain vitamin D2, which is unavailable immediately until the liver synthesizes the active substance. Top healthy foods rich in vitamin D: Salmon, Sardines, Tuna, Egg yolk,  Ghee butter (Grass-fed milk), Oysters, Tofu (Soya Non-genetically modified), Mushrooms, and Orange Juice. (Sweet - limited quantities)

Fear of contracting skin cancer and working indoors for many hours has created a situation in which many people, even in sunny countries, are deficient in vitamin D. (Taking vitamin D supplements is not equivalent to natural vitamin D.) The sun is the source of life, and it exists unlimitedly for free - it is essential to use this natural resource wisely. Controlled sun exposure is critical to the proper function of the immune system, above and beyond expectations. It does not cause skin cancer!

The Healing Power of Sunlight.

Moderate exposure to the sun has many benefits. (Suntanning is not the cause of skin cancer!)

1. Creates natural vitamin D. (Essential.)
2. Elevates testosterone (The male sex hormone), Thus improving erection. Women do not have masculine side effects.
3. It helps relieve pain.
4. Charges the Qi energy.
5. It helps relaxation and improves sleep.
6. It promotes good moods and prevents depression.
7. Rejuvenates scar tissue and skin problems. (Depending on the stage.)

Controlled sun exposure has additional benefits beyond vitamin D3 production.

My experience with sunbathing is immense.

Link: Sun tanning (Wikipedia)

In the early stages of my severe liver disease, I noticed that controlled tanning immediately improved my energy.

• I have over 15 years of experience with regular sunbaths; I have medium-bright skin with many freckles.
• I usually lie on the grass in short sports pants and without a shirt for 45 – 60 minutes once to twice a week.

Principles of controlled Solar Baths - Sunbathing.

Controlled sun exposure is often essential in the healing processes of chronic diseases.  

• Length of exposure should take into consideration:
  • Skin color.
  • Exposure can be more prolonged in wintertime when solar radiation is low.
  • Weather conditions.
  • Sun intensity.
• The maximum length of exposure is restricted to 45 minutes in summer and 60 minutes in winter. (It may not be more than twice a week.)
• Unless it is wintertime, the best hours for solar baths are in the morning or afternoon when the sun is less intense and less harmful.
• Exposure should be direct – not behind glass or using artificial tanning machines.
• Exposing as much skin surface as possible without applying sunscreen lotions is essential. (Except for the skin on the face and neck.)
• Before removing your clothes, drink water, wear a hat to protect your head, and wear sunglasses if the sun is intense.
• Expose the front and back of the body evenly, half-time for each side.

Protecting the skin of the face and neck.

• Sitting in the sun with a wide-brimmed hat and sunglasses is recommended. The skin of the face and neck is susceptible to sun damage. You can apply sunscreen to the face and neck only. (Only on a natural basis.)

Dead Sea sunbaths. (Especially beneficial for patients with chronic skin diseases.)

• The Dead Sea area's climate is hot and dry; since the temperature is very low, harmful ultraviolet radiation is partially blocked in the atmosphere.
• The Dead Sea is a unique place that charges the Qi energy faster than usual; I always feel much better afterward.

The Dead Sea is a salt lake between Israel and Jordan, well known for its health benefits to chronic skin patients.

• Many people with skin problems, including psoriasis, come worldwide to get cured in the Dead Sea sun and with the Dead Sea waters' unique minerals.

Vitamin B12, also known as cobalamin, is a water-soluble vitamin that plays a critical role in the proper functioning of the body. Here are some crucial reasons why vitamin B12 is essential (from ChatGPT) :

1. Formation of red blood cells: Vitamin B12 is necessary to produce red blood cells. Red blood cells carry oxygen to the organs and tissues, and a deficiency in vitamin B12 can result in anemia, which causes fatigue, weakness, and other symptoms.
2. Proper nervous system function: Vitamin B12 plays a critical role in the normal functioning of the nervous system. It forms myelin, a fatty substance that covers and protects nerve fibers. A deficiency in vitamin B12 can cause neurological symptoms such as numbness, tingling, and difficulty walking.
3. DNA synthesis: Vitamin B12 is necessary to synthesize DNA, which is the genetic material in all cells. Without enough vitamin B12, cells cannot replicate properly, leading to cell death and tissue damage.
4. Energy production: Vitamin B12 helps convert food into energy by breaking down carbohydrates, fats, and proteins. The body uses this energy for all its functions, from the heart's beating to the movement of muscles.
5. Mental health: Some studies suggest that vitamin B12 may affect mental health. A deficiency in vitamin B12 has been linked to depression, and supplementation with vitamin B12 may improve symptoms in some people.

Vitamin B12 cannot be synthesized in the liver and must be obtained through food. Vitamin B12 does not exist in plant products. The most recommended source of vitamin B12 is natural (unprocessed) animal products, especially free-range eggs and deep-water fish. In cases of significant deficiency, B12 injections are absorbed immediately.

Vitamins D3, B12, and Omega-3 are critical for proper immune function.

1. Is over-tanning the dominant cause of skin cancer?

Over-tanning can cause skin damage, especially to the face and neck. At the same time, controlled tanning is essential for our bodies and is not the cause of skin cancer! As experts believed.

 I rarely sunbathe.

 I take vitamin D3 supplements.

 The mistaken fear of skin cancer has caused large populations to avoid controlled exposure to the sun, which is the source of life on Earth.

 People with fair skin should not be exposed to the sun.

A more detailed explanation:

1. The most suitable answer is answer number 3.
Controlled exposure to the sun while wearing a hat and sunglasses. (without sunscreen) is recommended for immediate absorption of vitamin D3. (Critical for the proper functioning of the immune system)
