Research-Supported Benefits:

Supports Immune Health. Vitamin C deficiency can cause impaired immunity and higher susceptibility to infections, and supplementing with vitamin C reduces symptoms and shortens the duration of illnesses.1, 2

Supports Cellular Health. Vitamin C is a potent antioxidant that scavenges for free radicals, protecting cells from oxidative stress. Pro-C Complex also contains rose hips, acerola, rutin and citrus bioflavonoids that all act as antioxidants, including hesperidin, eriocitrin, naringin and narirutin.1

Supports Skin Health. Vitamin C is essential for healthy skin, as it is needed for collagen synthesis. Collagen production starts to decline as early as age 25, leading to wrinkles and sagging or thinning skin. Vitamin C also supports skin health through its role as an antioxidant, which helps to protect against UV damage.3

Enhances Iron Absorption. Recent research concluded “Vitamin C is the only dietary constituent other than animal tissue that has been shown to promote iron absorption”. 4

  • Vitamin C is an essential nutrient with powerful antioxidant properties that offers support for immune function. It also aids in wound healing, helps with collagen production and assists in the absorption of iron.
  • Vitamin C also supports cellular health and skin health, including boosting collagen synthesis for healthy skin, bones, cartilage, blood vessels, teeth and gums.
  • ProHealth’s Pro-C Complex™ is formulated using a unique buffered form of vitamin C with metabolites to enhance absorption, along with research-supported ingredients and dosing to address various aspects of health and longevity.
  • Calcium ascorbate neutralizes stomach pH to reduce stomach issues common with high vitamin C dosing. Additionally, calcium ascorbate increases absorption by 400% and remains in the body 3-4 times longer.
  • Acerola powder is a natural source of vitamin C and antioxidants that is more absorbable compared to the synthetic form of ascorbic acid.  
  • Rose hips powder is a natural source of vitamin C added to support immune health. It’s also shown to support collagen synthesis and reduce oxidative stress, which is known to contribute to premature aging. 
  • Rutin is a powerful antioxidant that supports the body’s use of vitamin C, protects from free radical damage, offers immune system support and increases the production of collagen.
  • The citrus bioflavonoid complex (hesperidin, eriocitrin, naringin, narirutin) work synergistically with vitamin C to neutralize free radicals and complement the antioxidant potency. In addition they’ve also been shown to support healthy circulation, joint health and cognition.*

Reduced Stomach Discomfort. Vitamin C is naturally acidic and high doses can lead to stomach discomfort. The form used in Pro-C Complex, calcium ascorbate, creates a more neutral pH which is easier on the digestive system.

Better Absorption. ProHealth’s Pro-C Complex™ is formulated using a unique buffered form of vitamin C with metabolites to enhance absorption. It’s absorbed 400% faster than regular vitamin C and is retained by the body as much as 3x longer.

Unique Formulation. Pro-C Complex™ contains ingredients specific to supporting immune health and reducing the risk of age-related health conditions. In addition to the unique antioxidants that have been added, such as rose hips powder, we also included vitamin C from calcium ascorbate for a high-quality source and calcium from calcium ascorbate to act as a “buffer vitamin C”.

Pro-C Complex

This is in a form that is more bio-available than the normal C that comes from rose hips. I feel like I am not flushing it down the drain. This actually works.
