Now Foods Vitamin A 25000 IU – 100 Capsules

Now Foods Vitamin A is a complément alimentaire designed to provide an essential nutrient that supports various bodily functions. Each capsule delivers a high potency dose of 25,000 IU of vitamin A, primarily in the form of retinol, sourced from fish liver oil. This product is particularly beneficial for individuals dealing with severe deficiencies, skin conditions—such as psoriasis and acne—as well as vision issues. It also plays a critical role in enhancing immune function, particularly during the colder months when immune systems may decline.

What is Vitamin A?

Vitamin A encompasses a group of organic chemical compounds classified as fat-soluble retinoids. These compounds are crucial for maintaining overall health. The recommended daily intake for adults ranges from 700 to 900 micrograms (µg). A severe deficiency in vitamin A can lead to significant problems, including impaired vision, skin disorders, and digestive complications.

Vitamin A Deficiency

Certain groups are particularly vulnerable to vitamin A deficiencies, including individuals who:
– Avoid animal products
– Follow long-term restrictive low-fat diets
– Consume alcohol excessively
– Smoke cigarettes

Symptoms of deficiency may manifest as:
– Night blindness (difficulty seeing in low light)
– Xerophthalmia (dry eyeballs)
– Extremely dry skin, particularly on the elbows et knees
– A general decline in immune system function
– In women, reduced vitamin A levels can lead to menstrual and fertility issues.

Vitamin A and Healthy Eyes

Historically, vitamin A deficiencies were linked to vision problems, particularly known as “night blindness” or “chicken blindness.” This was attributed to insufficient intake of retinol-rich foods. Vitamin A is vital for the production of rhodopsin, a pigment in the retina that is essential for normal vision.

Vitamin A for the Skin

Vitamin A is renowned for its ability to:
– Accelerate epidermal regeneration
– Reduce the appearance of scars and skin imperfections
– Strengthen skin’s protective functions and maintain proper hydration
– Support collagen and elastin production, promoting skin elasticity and firmness.

Regular intake can help minimize acne lesions, improve skin tone, and reduce wrinkles and discoloration. Furthermore, bêta-carotène, a precursor to vitamin A, acts as a natural sunscreen, enhancing skin resistance against UV radiation. It is also effective in treating conditions like herpes labialis and skin warts.

Activité antioxydante

As a prominent antioxidant, vitamin A helps combat the damaging effects of reactive oxygen species (ROS), thereby preventing oxidative stress. Oxidative stress can harm cells by causing mutations to DNA and proteins, potentially leading to metabolic diseases and an increased risk of cancer. Antioxidants like vitamin A play a vital role in restoring the balance in the body, counteracting free radicals, and protecting skin health from the aging process.
