What Is SportLegs Lactic Acid Supplement?

SportLegs is a lactic acid supplement that raises the threshold for lactate production in exercising muscles. The aim is to reduce the amount of lactate the muscles produce, reducing the amount of lactic acid waste.

The reduction of this waste in exercising muscles means less pain during long rides or a long training run. Lactic acid is a byproduct of anaerobic respiration in exercising muscles.

SportLegs works by introducing lactate into the body before exercise. This triggers lactate production and ensures that only the lactate required is produced when muscles are worked.

Does SportLegs Work?

There is very little evidence that this kind of supplementation actually affects the amount of pain felt after working out, and some users claim the supplement has the placebo effect – only working because you want it to.

There is some evidence that muscles may use lactic acid as fuel when working out. This means that the SportLegs supplement could help endurance by providing another fuel source.

In addition, one study found that lactate triggers the production of MCTs, which can boost the endurance of your muscles and enhance athletic performance in much the same way as supplementing with MCT oil.

SportLegs claims to reduce the burn caused by lactate build-up in the muscles, but the theory that lactic acid causes burning and soreness was debunked in the 1980s. This means that this supplement may have no effect on soreness at all.

Furthermore, a 2012 double-blind study found that lactate supplementation had little effect on cyclists’ performance when undertaking three laps of 20km. A later study, carried out in Brazil, showed similar results too.

While the science is lacking, there are a number of hypotheses that could explain how the supplement works. However, with limited evidence, it is hard to say whether SportLegs will work.

3 Benefits of SportLegs Supplements

SportLegs user reviews are mixed, but some users have found it to be a beneficial supplement for endurance training. Below, we’ve summarized some of the possible benefits of this supplement.

#1 Reduces muscle burn and cramping

SportLegs users have found that this supplement reduces muscle cramping. There is evidence to suggest that lactate build-up has an effect on cramping and could contribute to fatigue in muscles.

By supplementing with lactate and lowering the threshold for lactate production, this supplement helps reduce cramps and fatigue after long rides, runs, and exercise sessions.

Other methods of reducing cramping include ensuring you drink plenty of water and stay hydrated, keeping your electrolytes in balance, and stretching before long-distance runs and hard workouts.

#2 Enhances athletic performance

New evidence suggests that, while lactate has long had a bad reputation, it may, in fact, be used as a fuel source by the body. This means SportLegs could offer further fuel to the muscles, enhancing athletic performance.

In addition, some evidence suggests that lactate may stimulate the release of MCTs. MCT oil is frequently used as a supplement for exercise due to its ability to enhance athletic performance and endurance.

This study was carried out years ago, and the area of knowledge is in need of development. Nevertheless, the theory is sound and offers support for the SportLegs supplement.

#3 Promotes faster recovery times

Though evidence has shown that fatigue is caused by a number of factors that include lactate, lactate supplementation can help reduce fatigue and, therefore, recovery times.

It is assumed that recovery rates are faster when lactate is removed from the blood quickly after exercise. Lactate supplementation can reduce the amount of lactate build-up, so there is less to remove.

5 Side Effects of SportLegs Pills

As with any supplement, SportLegs comes with some negative side effects. Below, we have summarized a few of the most common ones.

#1 Could lead to hypercalcemia

Hypercalcemia is characterized by extremely high levels of calcium in the bloodstream. Calcium is essential in the body, but too much can cause problems.

Symptoms of too much calcium in the blood include headaches, fatigue, excessive thirst, and urination. Supplementation of calcium may also result in constipation.

Hypercalcemia is only a danger if you take too much of this supplement. Provided you stick to the recommended dosage, you will be very unlikely to experience hypercalcemia.

#2 Could interact with some medications

The calcium lactate present in this supplement may lead to unwanted complications with certain medications. Medications it could interact with include diuretics, antibiotics, and anti-seizure medications.

Speak with a doctor before taking the SportLegs supplement if you’re concerned about any interactions.

#3 May lead to digestive problems

Calcium lactate has been known to cause constipation and other digestive problems. These side effects may occur during the early stages of your usage. If they continue or get worse, stop taking SportLegs.

Additionally, the magnesium in SportLegs can cause digestive issues, particularly in people already getting a lot of magnesium in their diet.

#4 May cause mild stomach upset

The SportLegs manufacturers state that mild stomach upset has been reported in the years that the supplement has been on the market. This may be because users take the supplement on an empty stomach.

There is no data on how frequently this occurs and may not affect you when taking the SportLegs supplement.

#5 Could cause an allergic reaction

Though very rare, there is some risk of allergic reactions. Symptoms of an allergic reaction include hives, swollen lips and eyes, difficulty breathing, rapid heart rate, and loss of consciousness.

If you have had any adverse reactions to any of the ingredients within the supplement, avoid taking it. If you experience any symptoms of an allergic reaction, seek emergency medical attention.

What Ingredients Does the SportLegs Supplement Contain?

SportLegs uses a special blend of ingredients that are designed to induce less pain after workouts and enhance athletic performance. Take a look below to find out how each of them works.

Vitamin D

Vitamin D has many benefits for exercise and recovery. To begin with, vitamin D has musculoskeletal benefits. It plays an important role in bone health.

Additionally, it increases muscle protein synthesis and increases ATP concentration prolonging aerobic respiration in muscles. Indeed, there is some evidence that supplementation of the vitamin can increase overall performance.

You also need vitamin D to be able to absorb calcium. Calcium is a prominent ingredient in SportLegs.

Vitamin D supplementation may cause constipation in some.

Calcium

Calcium is essential in the body and is needed for strong bones. It is also needed for muscle movements, including contractions, and stabilizes blood pressure during exercise. Increasing your daily calcium intake is helpful for better athletic performance.

In the SportLegs supplement, the calcium acts as a transporter for the lactate, helping it effectively penetrate the muscles.

Magnesium

Magnesium supplementation is thought to enhance athletic performance and has benefits for recovery, too. Though magnesium is used as a transportation method for lactate in the supplement, magnesium still supports better performance.

Magnesium is essential in the body. It supports muscle function and energy production, and getting enough is important for your health.

Lactate

Lactate is the active ingredient in this supplement. It is used to reduce the threshold for lactate production.

The main benefits of this ingredient include reducing muscle soreness and recovery times. It will also reduce cramping and pain.

Stearic acid

Stearic acid is a long-chain fatty acid that is found in plant and animal compounds. It is a major component of cocoa butter and shea butter. It has anti-inflammatory properties and is used in a variety of biomedical applications.

Silica

Silica is a natural compound found in rocks and clay. It supports bone formation and stimulates the production of collagen. Collagen protects joints, which is useful for frequent runners. 

In supplements, it is frequently used to stop the formula from clumping together.

How We Tested

When we review supplements, we aim to give as much information as possible to help our readers make an informed decision. In addition, we aim to review products fairly based on four categories: quality, effectiveness, price, and brand reputation.

Quality

Quality is key to our health. If you’re taking a supplement to boost your health, then you need to make sure it is of good quality and safe for you to take.

The SportLegs product is generally considered to be of good quality. The manufacturers claim to double-test ingredients and get them from reputable sources.

When choosing supplements, whether for running or to boost your mineral intake, it is very important to ensure all ingredients are of the highest quality to ensure safety.

Effectiveness

Effectiveness is just as important as quality when it comes to health supplements. You need to make sure the product you’re taking does what it says on the label; otherwise, it is pointless.

The SportLegs product may be effective. Some users have reported lots of success and have recounted incredible benefits from this product.

On the other hand, the science behind the supplement is lacking, and not much is really known. Very little has been confirmed in research carried out on lactate supplementation.

Price

Price is important when we review products because we believe good health should be accessible. Products that help your health shouldn’t cost the earth.

SportLegs is an extremely accessible supplement, costing only $29.95 for a bottle containing 120 pills. 

You can also find a trial pack of the supplement to help you decide whether to take it.

Brand reputation

The reputation of a brand can be the difference between a good product and an excellent product. If a brand is reputable, it is more likely to produce quality and effective products.

SportLegs has got a good reputation in the wellness space, which means it is likely a good product. It is safe and may have some benefits for training.

FAQs

Is it good or bad to use SportLegs Pills?

SportLegs pill reviews vary as to the efficacy of the pill, but the product is safe and suitable for use before training. Take the recommended dose before a training session for the best results.

Is the SportLegs Supplement safe to use?

The SportLegs supplement is completely safe to use. The manufacturers double-test all ingredients and source them from reputable places.

Is it okay to take SportLegs every day?

SportLegs is not designed to be taken every day. Instead, you should take it before you intend to work out.

Where can I buy SportLegs pills?

SportLegs pills can be found on the manufacturer’s site. They may also be found in health stores and on marketplaces like Amazon.

What is the recommended daily dosage?

The manufacturers recommend you take one pill per 50 pounds of body fat. This means if you weigh 125 pounds, you should take three pills.

A Word From Our RD

Lactate supplementation has been researched as a method of enhancing athletic performance and speeding up recovery. Though research is fairly limited, many regular runners and cyclists choose to use this form of supplementation.

Though lactate was thought to be a bad compound years ago, this theory has been debunked, and we now know it could actually act as a fuel source.

Additionally, another study performed a few years ago suggested that lactate stimulated the release of MCT. MCT oils are used in supplementation to enhance athletic performance, too, as they are thought to increase muscle endurance.

Though there could be some benefits to lactate supplementation, many research studies have shown little to no change in the athletic performance of cramping in the legs felt by people after working out.

Other aspects of lactate supplementation have a more definite impact on health and athletic performance. Many lactate supplements use calcium as a carrier. Calcium is essential in the body.

By helping muscles contract and increasing bone health, calcium is incredibly useful during exercise. Calcium can be found in many different kinds of food, but it can also be supplemented.

Lactate supplements may also contain magnesium as a carrier. Magnesium, like calcium, is an essential mineral in our body. There is evidence to suggest that it boosts athletic performance.

While lactate supplements can boost performance, endurance, and recovery, you can also take other measures. You should ensure that your electrolytes are balanced and that you drink plenty of water.

You should also ensure that you stretch before training and perform a proper cool down to reduce muscle soreness and pain the next day. If you find you still feel tired the next day, you may need to adjust your training to better suit your fitness levels.

Lactate supplementation has been found useful by many people who exercise and could also help you to reduce soreness and fatigue.

Conclusion

The SportLegs supplement is a lactate supplement designed to help reduce soreness and fatigue after long workouts. It works by reducing the threshold for lactate production and ensures the muscles only make as much as they need.

User reviews are mixed on how effective SportLegs actually is, and the science may not fully back the manufacturer’s claims. For that reason, it may be best for you to try an alternative supplement.
Look out for quality supplements that help reduce soreness, like the Nuun Hydration Supplements.
