A powerful nutritional supplement from Swanson, specially designed with a focus on your immune system. A formula carefully created with the presence of vitamins A and D, which work in synergy together to simultaneously support both your vision and skin, as well as your immune system.
A nutritional supplement combining vitamins A and D to make it easier to obtain the daily amounts needed for the proper functioning of the body. In combination, the two vitamins have an extremely beneficial effect on people! That is why experts recommend them.
Vitamin D
Most people need more vitamin D3 because low levels and deficiencies of this important micronutrient are increasingly common in the population, and experts around the world are recommending changes to the recommended daily allowance of vitamin D3 because most of us don’t get enough. Vitamin D3 is important for healthy bones, a strong immune system, and mental and emotional health. Sunlight is responsible for the production of vitamin D in the body, but our production capacity is limited, especially during the winter months when sunlight is limited and due to unhealthy lifestyles and excess weight. The recommended daily allowance of vitamin D is currently between 200 IU and 600 IU, depending on the age, weight, and health status of the individual.
In addition to the primary way of producing vitamin D (exposure to sunlight), a person can also obtain this micronutrient through certain animal foods such as fish and eggs and dairy products with added vitamin D. Supplementation is an easy and effective way to increase blood levels of vitamin D, since its amounts in food are limited.
Specifically, vitamin D supplementation has been scientifically proven (from human clinical trials) to be effective in reducing the risk of: falls and fractures in older adults, cardiovascular disease and related complications, colon cancer, breast cancer, blood pressure, all-cause mortality, influenza, multiple sclerosis, arthralgia (joint pain). Vitamin D may also help reduce: body fat in people trying to lose weight, asthma attacks, tuberculosis symptoms, type 1 diabetes in children of pregnant women taking vitamin D supplements. This important micronutrient is also effective in increasing the strength of the nervous and muscular systems in adults, insulin production, and better insulin sensitivity in type 2 diabetics, leading to better blood sugar control. Vitamin D also increases testosterone levels in men, which can help maintain healthy hormone levels as a person ages.
The preferred form for supplementation is vitamin D3 (the animal form) over vitamin D2 (the plant form) because a smaller dose of vitamin D3 is needed to raise blood levels of vitamin D. It is best to take vitamin D3 with a meal containing at least 10 grams of fat, as this improves its absorption significantly compared to low-fat meals.
Vitamin A
Animal forms of vitamin A (retinoids) are found in foods such as eggs, liver, cheese and whole milk and are different from the plant form (beta carotene), which is found mainly in carrots, sweet potatoes, pumpkin, spinach and kale, and fruits such as melons and apricots. Maintaining optimal levels of vitamin A is a key factor for good vision and eye health, a strong immune system, growth and development (especially for children), skin health, lower rates of skin aging and a reduced risk of night blindness and dry eyes.
Retinoids are used as a treatment for acne and various skin problems such as wrinkles and have been shown to be effective in both oral (capsule) and topical forms. Vitamin A deficiency can lead to measles and dry skin, and retinoid supplements are the recommended treatment. Vitamin A may also treat various diseases such as leukemia, various cancers, HIV, and cataracts, with ongoing studies testing the effectiveness of vitamin A supplementation.
People with poor diets and digestive problems that lead to poor nutrient absorption are at increased risk of vitamin A deficiency and therefore it is advisable for them to supplement. Since this important nutrient is fat-soluble, it is optimal to take it with a meal rich in fat.
Caution should be exercised when taking high doses of vitamin A, especially if users are smokers or drink heavy amounts of alcohol. Also, since vitamin A is fat-soluble, it can accumulate in fat cells for long-term storage. If high levels are taken continuously for a long time, high levels of vitamin A can accumulate, which can cause liver and kidney problems, and it is better to take this supplement intermittently rather than continuously.
