Vitamin E & C

What it is: Vitamin E is a group of fat-soluble antioxidant compounds known as tocopherols, whereas Vitamin C, or ascorbic acid, is a water-soluble vitamin essential for human health. Both are required because the body cannot produce them on its own.
What it does: Vitamin E works mainly to protect cell membranes from oxidative damage, while Vitamin C supports immune defense, is needed for collagen synthesis, and helps regenerate Vitamin E after it has neutralized free radicals. Together, they maintain cellular health and antioxidative balance.
How it is used: These vitamins are frequently taken together for their complementary antioxidant effects, supporting immune function, skin appearance, and general wellness. They are popular in products focused on overall vitality, skin support, and immune resilience.
Natural sources and supplement forms: Vitamin E naturally occurs in nuts, seeds, and plant oils, and is often labeled as d-alpha-tocopherol or mixed tocopherols in supplements. Vitamin C is abundant in citrus fruits, berries, peppers, and leafy green vegetables, with common supplement forms including ascorbic acid and sodium ascorbate.
Why it appears in supplement formulas: These vitamins are combined for their synergistic antioxidant roles, as Vitamin C can regenerate oxidized Vitamin E, enhancing overall oxidative stress protection for skin, immune cells, and body tissues.
What to know before use: High doses of Vitamin E may increase bleeding risk, especially with blood-thinners, and excess Vitamin C can cause digestive upset. Consult a healthcare professional if you have underlying conditions or take medications.
