Vitamin C
Also known as: Ascorbic acid
Powerful antioxidant that supports collagen production and helps reduce oxidative stress. Essential for skin health and overall wellness.
What it is
Vitamin C is a water-soluble antioxidant vitamin that your body can't produce itself. It's a required cofactor for building collagen and helps protect cells from everyday oxidative stress.
Why we use it
We pair vitamin C with collagen and hyaluronic acid because vitamin C is directly involved in collagen synthesis — without enough of it, the collagen-building process is less efficient.
What the research generally suggests
Vitamin C's role in collagen production is well documented; research on antioxidant supplementation more broadly suggests a general supportive role in cellular health rather than dramatic standalone effects.
Typical amounts
Common supplement doses range from around 20mg (topping up a normal diet) to 500mg+ (higher-dose antioxidant support); doses above 1000mg/day can start to cause digestive upset in some people.
In Flexies products: 20-40mg per serving.
