Why You Need to Keep Lactic Acid in Check for Better Health—Before It Takes a Toll
Lactic acid is often misunderstood—it’s not just about sore muscles after a workout. 

This naturally occurring compound plays a vital role in energy production and metabolism, but when it builds up too much, it can contribute to fatigue, discomfort, and even metabolic stress.
Now that we’ve covered what lactic acid does, let’s talk about how to keep it balanced to work for you—not against you.

Lactic Acid & Your Health
If you struggle with diabetes, heart issues, or chronic fatigue, managing lactic acid can help reduce discomfort. 

Things that affect lactic acid levels include:
  • Blood Flow & Oxygen – When circulation is sluggish, lactic acid sticks around longer, making you feel drained.
  • Hydration & Electrolytes – Not drinking enough water can lead to lactic acid buildup, causing cramps and muscle tightness.
  • Metabolism – Your body naturally clears lactic acid through breathing, movement, and digestion, so keeping those processes running smoothly is key.
Best Foods to Help Balance Lactic Acid
Certain foods can help regulate lactic acid, ease muscle tension, and boost energy:
  • Citrus Fruits (Oranges, Grapefruit, Lemons) – Vitamin C helps neutralize excess acidity.
  • Leafy Greens (Spinach, Kale, Arugula) – Magnesium helps muscles clear lactic acid.
  • Plant-Based Proteins (Lentils, Chickpeas, Tofu) – Support muscle recovery and prevent buildup.
  • Bananas & Other Potassium-Rich Foods – Keep muscles from cramping and help clear excess acid.
  • Fermented Foods (Kimchi, Sauerkraut, Miso) – Support digestion and lactic acid metabolism.
Simple Ways to Keep Lactic Acid in Check
Beyond food, your daily habits play an improtant role in keeping lactic acid from building up too much:
  • Keep Moving (but don’t overdo it) – Light stretching or walking after a workout helps accumulated lactic acid clear out.
  • Stay Hydrated – Drinking enough water helps flush excess lactic acid.
  • Breathe Better – Deep breathing improves oxygen flow and prevents buildup.
  • Get Enough Rest – Quality sleep gives your body time to clear lactic acid overnight.
Lactic acid isn’t something to fear—it’s a natural part of how your body produces energy. The key is managing it to work with you, not against you. Small changes to your movement, hydration, and diet can make a big difference in how you feel!

This blog is dedicated to Irl Flanagan, who was my friend and grammar mentor. Over the last 20 or so years, he spent countless hours editing my manuscripts and teaching me the intricacies of sentence structure and the true meaning and the proper usage of words. 

Irl died 4 months before his 100th birthday.

About Me

I’m Peggy Kraus, an exercise physiologist and diabetes care and education specialist. My clients often tell me my superpower is helping people reverse type 2 diabetes — but the impact goes far beyond blood sugar.

After almost 30 years in cardiac rehab, I’ve seen how the American diet has affected people’s lives. I know health isn’t just about managing symptoms. It’s about reversing disease when possible, feeling strong and energized, and getting your life back.

I’ve helped thousands of people lower blood sugar, lose weight, improve cholesterol, and reduce blood pressure — all through simple, strategic lifestyle changes rooted in science and compassion.

My signature 6‑week program, 5 to Thrive, teaches the five key strategies my most successful clients use to create lasting change. And my newest program, Diabetes Rescue, is helping people move toward type 2 diabetes remission with a bold, plant‑powered approach that gives them the tools, support, and confidence to take back control of their health.

A plant‑based lifestyle is powerful. And so are the results my clients achieve.
