Zinc plays a critical role in maintaining healthy skin and may be beneficial for individuals suffering from acne. Acne is often caused by inflammation and bacterial growth on the skin. Zinc’s anti-inflammatory and antibacterial properties can help alleviate acne symptoms by reducing inflammation and inhibiting the growth of acne-causing bacteria. Additionally, zinc is involved in collagen synthesis, which is essential for wound healing and maintaining the integrity of the skin. Therefore, zinc supplements may play a role in promoting clearer, healthier skin.

Wound healing

Zinc is necessary for proper wound healing and tissue repair. It is involved in various stages of the wound healing process, including cell proliferation, collagen synthesis, and immune response modulation. Research has shown that zinc supplements can accelerate the healing of both acute and chronic wounds, such as surgical incisions and ulcers. By supporting the wound healing process, zinc supplements can aid in the restoration of damaged tissues and promote faster recovery.

Recommended Dosage and Sources of Zinc

Daily recommended intake
