Supporting POTS: Nutrition, Lifestyle Strategies, and Practical Tools

I thought it might be helpful—and honestly, a little fun—to share some product highlights that I recommend for the right patients managing Postural Orthostatic Tachycardia Syndrome (POTS).

As dietitians, our role is not to replace medical care, but to work alongside physician recommendations and help patients implement them in a way that is realistic, sustainable, and individualized. POTS management looks different for everyone, and what works well for one person may not work for another.

That said, non-medication management of POTS often includes several foundational lifestyle strategies.

Core Lifestyle Approaches Commonly Recommended for POTS

Increased sodium and fluid intake
Many patients are advised to consume approximately 7–10 grams of sodium per day along with 2–3 liters of fluid daily. This approach can help expand blood volume, making it easier for blood to circulate throughout the body. These targets should always be personalized and guided by a medical provider.

Mindful use of caffeine and alcohol
Both caffeine and alcohol can affect fluid balance and may worsen symptoms for some individuals. Tolerance varies, so careful monitoring is important.

Consistent, non-upright exercise
Exercise is a key part of long-term management, though it must be approached carefully. Non-upright or recumbent forms of cardio combined with strength training are often better tolerated. Because tolerance levels vary significantly, working with a physical therapist and/or physician is strongly recommended.

Compression garments
Compression applied to the abdomen or lower extremities (legs and feet) can help support venous return. This strategy may not be helpful for everyone, but it is often worth trialing.

Meal size, timing, and composition
Large, high-carbohydrate meals can redirect blood flow toward digestion, sometimes worsening symptoms such as lightheadedness or fatigue. Many patients report improved tolerance with smaller, more frequent meals. Taking this a step further, protein-forward meals (when tolerated) may offer additional benefit. As with all aspects of POTS, this is highly individualized.

Translating Recommendations Into Real Life

Understanding these strategies is one thing—implementing them consistently is another. This is where nutrition support can be especially valuable. Practical tools, including specific foods, beverages, and products, can make it easier to meet sodium and fluid targets while fitting into daily routines.

There are a number of helpful products that can make meeting these recommendations more manageable and may support blood volume for certain individuals. These are recommended on a case-by-case basis and should always align with each patient’s medical plan.

I often recommend these options in place of relying on salty snack foods, as this approach can help support sodium needs without unintentionally displacing more nutrient-dense foods or leading to overconsumption of higher-calorie, lower-nutrient snacks.

If you’re managing POTS—or supporting someone who is—remember that progress often comes from layering small, sustainable changes over time, not from doing everything perfectly all at once. Consider working with a dietitian to address and implement nutrition recommendations (food, fluids, electrolytes) to help improve energy levels, digestion and reduce symptoms.
