When you exercise hard, your muscles can feel tired and sore. This happens because of lactic acid. Lactic acid builds up in your muscles when you work out. It can cause burning and tired feelings. Many people want to know how to lower lactic acid fast. One way is by taking supplements. But what supplement helps reduce lactic acid? This article will explain it in simple words.
What Is Lactic Acid?
Lactic acid is a chemical made in your muscles. When you do hard exercise, your body uses energy fast. Sometimes, it does not get enough oxygen. When this happens, your body makes lactic acid. Lactic acid helps your muscles work even without oxygen. But too much lactic acid can cause pain and tiredness.
After exercise, lactic acid leaves your muscles. Your body changes it into energy or removes it. If lactic acid stays long, it can make your muscles sore.
How Can Supplements Help?
Supplements are vitamins, minerals, or other substances. People take them to help their body work better. Some supplements help your body clear lactic acid faster. Others help your muscles use energy better. This can stop lactic acid from building up too much.
Not all supplements work the same. Some are better for reducing lactic acid. Let’s look at the best ones.
Best Supplements to Reduce Lactic Acid
Here are some popular supplements that help with lactic acid:
- Bicarbonate (Sodium Bicarbonate)
- L-Carnitine
- Beta-Alanine
- Magnesium
- Vitamin B Complex
- Alpha-Lipoic Acid (ALA)
1. Bicarbonate (sodium Bicarbonate)
Bicarbonate is a substance that helps balance acid in the body. It is also called baking soda. Taking bicarbonate can help stop lactic acid from making muscles too acidic. This means less burning and pain during exercise.
Many athletes use bicarbonate before workouts. It helps them last longer and feel less tired. But taking too much can cause stomach problems. Always take the right amount.
2. L-carnitine
L-Carnitine is a natural nutrient. It helps your body use fat for energy. When your muscles use fat, they make less lactic acid. This helps reduce muscle soreness.
Some studies show L-Carnitine can help muscles recover faster. It may also reduce muscle damage during exercise. You can find L-Carnitine in capsules or drinks.
3. Beta-alanine
Beta-Alanine is an amino acid. It helps your muscles make carnosine. Carnosine helps stop acid build-up in muscles. This means less lactic acid effect and less burning.
Many athletes take beta-alanine to improve their performance. It helps during short, hard exercise. Like running fast or lifting weights.
4. Magnesium
Magnesium is a mineral important for muscles. It helps muscles relax after work. If you have low magnesium, you may feel cramps and soreness.
Magnesium helps your body make energy and clear lactic acid. Many people do not get enough magnesium in their diet. Taking magnesium supplements can help reduce muscle pain.
5. Vitamin B Complex
Vitamin B complex includes several B vitamins. They help your body make energy from food. When energy is made well, muscles work better and make less lactic acid.
B vitamins also help clear lactic acid faster. Taking a vitamin B complex can support your muscles during exercise.
6. Alpha-lipoic Acid (ala)
Alpha-Lipoic Acid is an antioxidant. It helps protect cells from damage. ALA can help muscles use energy better. This can reduce lactic acid build-up.
Some studies show ALA helps muscle recovery after exercise. It also supports overall muscle health.
