5 supplements for heat intolerance

As global temperatures rise, staying cool, especially during those scorching summer days, is more important than ever. Heat-related illnesses, such as heat stroke, are no joke—they can have severe, even fatal, consequences.

The basics of staying cool.

Heat stroke is a critical condition that occurs when your body loses its ability to regulate temperature, leading to a rapid increase in body heat. †

In severe cases, within just 10 to 15 minutes, body temperature can soar to 106°F (41°C), potentially causing lasting damage or death.

To keep cool and prevent overheating, here are a few tips:

  • Opt for light and airy clothing.

  • Cut back on caffeine.

  • Drink plenty of cold fluids to stay hydrated.

  • Try to stay indoors during peak sun hours.

Adding certain supplements to your routine can also help combat heat-related issues. Here are five top picks:

Why They Help: Electrolytes, including sodium, potassium, calcium, and magnesium, are vital for fluid balance and supporting key bodily functions.

Heat Connection: In the heat, you're at risk of dehydration, which zaps crucial electrolytes. Keeping your electrolyte levels balanced helps your body sweat and cool off effectively.

Where to Find Them: While sports drinks are popular, look for lower-processed sugar options to replenish your electrolytes.

Folic acid.

Why It Helps: Essential for creating DNA and forming red blood cells, folic acid plays a vital role in cell health.

Heat Connection: As we age, our blood flow might decrease, upping our risk for heat-related issues. Folic acid can help keep blood vessels functioning properly, aiding in body temperature regulation.†

Where to Find It: You can get folic acid from leafy greens, fortified foods, or dietary supplements.

Image of foods that contain magnesium



Why It Helps: Involved in over 300 biochemical reactions, magnesium is key for energy production and protein synthesis.

Heat Connection: Studies suggest magnesium is important for regulating body temperature, making it crucial for warding off heat stress, especially with repeated exposure.†

Where to Find It: Look to nuts, seeds, leafy greens, whole grains, and supplements for your magnesium fix.

Image of foods that contain potassium



Why It Helps: As an electrolyte, potassium is vital for the heart, muscles, and nerves, helping to manage fluid balance.

Heat Connection: Those taking diuretics might have lower potassium levels, increasing the risk of heat stroke and heart issues. Potassium supplements can help mitigate these risks.†

Where to Find It: Bananas, oranges, potatoes, and beans are great sources, along with supplements.

Vitamin E.

Why It Helps: This antioxidant shields cells from damage, supports the immune system and maintains skin health.

Heat Connection: Vitamin E is known for easing hot flashes during menopause, which could benefit heat tolerance.†

Where to Find It: Get your Vitamin E from nuts, seeds, spinach, and broccoli, or consider a supplement.
