3. How do you raise your sodium level?

To raise sodium levels, you can incorporate sodium-rich foods into your diet, consume sports drinks or electrolyte solutions, or consider taking sodium supplements. These methods can help increase your sodium levels if they are low.

4. Is it safe to take sodium supplements?

Taking sodium supplements orally is generally safe when used in doses less than 2.3 grams daily.

It is important to follow recommended dosages and consult with a healthcare professional before starting any supplementation.

5. How do you fix a low sodium?

If your sodium levels are low, it is recommended to consume sodium-rich foods such as fresh or frozen fruits (berries, apples, bananas), grains and beans (dried beans, brown rice, quinoa), starchy vegetables (potatoes, sweet potatoes, butternut squash), and fresh or frozen meat and poultry (chicken, turkey, beef, pork).
