Vitamins in Kirkland Mature Multi
Kirkland Mature Multi is packed with a wide spectrum of vitamins, each playing a critical role in maintaining health as you age. The formulation is tailored to address specific nutritional needs that become more pronounced after the age of 50.
Fat-Soluble Vitamins
These vitamins are absorbed with fat and stored in the body's fatty tissues and liver. The Kirkland formula includes:
- Vitamin A (as Beta Carotene): Essential for vision, immune function, and cell growth. The inclusion of beta carotene, an antioxidant precursor to Vitamin A, is particularly beneficial.
- Vitamin D3 (Cholecalciferol): Crucial for calcium absorption and maintaining strong bones, muscle function, and immune health.
- Vitamin E: A potent antioxidant that helps protect cells from oxidative stress and damage caused by free radicals.
- Vitamin K: Important for healthy blood clotting and bone health.
Water-Soluble Vitamins
These vitamins dissolve in water and are not stored in the body for long, requiring more consistent replenishment. The B-complex group is particularly vital for cellular energy production.
- Vitamin C: A powerful antioxidant that supports the immune system and promotes healthy skin.
- B-Complex Vitamins (B1, B2, Niacin, B6, Folic Acid, B12, Biotin, Pantothenic Acid): This complete family of B vitamins is included to support cellular energy production, nerve function, and red blood cell formation. Special emphasis is placed on Vitamin B12, as absorption can decrease with age.
Minerals and Other Key Ingredients
Beyond the primary vitamins, the Kirkland Mature Multi contains a host of minerals and other beneficial compounds designed for mature adults.
- Calcium: A critical mineral for building and maintaining strong bones and teeth. The formula includes calcium carbonate and dibasic calcium phosphate to ensure sufficient intake.
- Magnesium: Aids in muscle and nerve function, blood sugar control, and blood pressure regulation.
- Zinc: Supports a healthy immune system and cell metabolism.
- Selenium: An important trace mineral that acts as an antioxidant, supporting thyroid and immune health.
- Copper and Manganese: Needed for energy production and antioxidant protection.
- Chromium and Molybdenum: Trace minerals that play a role in metabolism.
- Lycopene and Lutein: These carotenoids offer antioxidant benefits and are associated with eye health.
