Zinc Ascorbate

Zinc Ascorbate is a unique dietary supplement that combines two powerhouse nutrients: Zinc and Vitamin C. Unlike taking them separately, in this compound form, they work synergistically to support your immune system, skin health, and antioxidant defenses. Think of it as a 'dynamic duo' for your body—while Vitamin C helps protect cells from damage, Zinc helps build and repair them. This combination is often favored for its gentle effect on the stomach compared to other zinc forms, making it an excellent choice for daily maintenance.

Health Benefits & Sources

Why You Need It

  • Boosts Immune Defense: Helps activate white blood cells to fight off infections.
  • Promotes Skin Repair: Essential for collagen synthesis and wound healing.
  • Powerful Antioxidant: Neutralizes free radicals that cause aging and cellular damage.
  • Gentle on the Stomach: Ascorbic acid can make this form of zinc easier to absorb and less likely to cause nausea.

Deep Dive

Zinc Ascorbate provides a bioavailable source of two essential micronutrients. Zinc is a trace mineral required for the activity of over 300 enzymes, while Vitamin C (ascorbic acid) is a vital water-soluble vitamin. Together, they support the integrity of skin and mucous membranes, your body's first line of defense. This specific salt form is particularly interesting because the ascorbate portion may help stabilize the zinc, potentially improving its uptake in the digestive tract. It is widely used to shorten the duration of common colds and support overall vitality.

Natural Food Sources

Zinc Ascorbate is a manufactured compound and does not exist naturally in food. However, you can consume Zinc and Vitamin C separately through a whole-food diet.

High doses of Vitamin C may cause loose stools in sensitive individuals. Consult a doctor if you have kidney disease or hemochromatosis (iron overload).
