Heat rash, also known as prickly heat, is a common skin irritation that appears when sweat becomes trapped under the skin. It often shows up as small red bumps, itching, or a prickling sensation—especially in hot, humid environments. While it’s usually not dangerous, heat rash can be very uncomfortable and can make it difficult to rest or focus on daily activities.
Along with keeping cool, wearing breathable fabrics, and staying hydrated, certain natural supplements may help reduce inflammation, support skin healing, and make the skin more resilient to irritation.
Below are two evidence-based supplements that can help support people dealing with heat rash.
Vitamin C
Vitamin C is a powerful antioxidant that supports skin repair and helps reduce inflammation. Because heat rash is aggravated by oxidative stress and irritation, supplementing with Vitamin C can promote faster healing and reduce the severity of flare-ups. It also strengthens the immune system, helping your body better respond to stressors that trigger skin issues.
- Mechanism of action: Reduces oxidative stress and supports collagen production for skin repair
- Dosage or usage tip: 500–1,000 mg daily, ideally split into two doses for better absorption

Zinc
Zinc is an essential mineral for skin health and immune function. It plays a key role in wound healing and helps regulate the skin’s oil and sweat production, which may reduce the risk of pores becoming clogged and inflamed during heat rash episodes. Zinc also has natural anti-inflammatory properties that can calm irritated skin.
- Mechanism of action: Promotes skin healing and regulates sweat gland activity
- Dosage or usage tip: 15–30 mg daily, taken with food to improve absorption

Summary
Heat rash can be bothersome, but natural supplements may provide supportive relief. Vitamin C helps reduce inflammation and repair irritated skin, while zinc supports healing and helps regulate sweat gland function. Combined with lifestyle measures like staying cool and hydrated, these supplements can help make heat rash less frequent and less uncomfortable.
Always check with a healthcare professional before starting new supplements, especially if heat rash is severe, recurrent, or associated with other concerning symptoms.
