Vitamin D & K Supplement Review: Effective but Pricey Choice


I know it is important to take vitamin D with Vitamin K and this makes us very easy. 4stars only because it is rather expensive for D and K. Very pleased.


Vitamin Basics & Tips


Vitamin A plays a critical role in maintaining vision, immune function, and skin health. Found in foods like carrots, sweet potatoes, and spinach, it exists in two forms: preformed vitamin A (retinol) from animal sources and provitamin A carotenoids (like beta-carotene) from plants. Adequate intake prevents night blindness and supports cellular growth.


While vitamin A is essential, excessive consumption can lead to toxicity, causing symptoms like dizziness or liver damage. Pairing it with healthy fats enhances absorption, and it often works synergistically with vitamins D, E, and K for optimal nutrient balance. Always consult a healthcare provider before starting supplements, especially during pregnancy.


In skincare, vitamin A derivatives like retinol are popular for anti-aging benefits, promoting collagen production and reducing wrinkles. However, sensitivity to sunlight increases with topical use, necessitating sunscreen. A balanced diet typically meets daily needs, making supplements unnecessary unless deficiencies are confirmed.
