Kola Nut: The Little-Known Ingredient that Supports Energy Levels

Although few people have ever heard of the kola nut, it’s a common ingredient found in everything from soft drinks to herbal supplements. Not only does this nutritious nut boast a unique flavor and aroma, but it’s also brimming with caffeine as well.

In fact, each pod packs the equivalent caffeine content of about two cups of coffee nutrition, along with a host of antioxidants and other health-promoting compounds.

What is the kola nut?

The kola nut, sometimes also called the cola nut, is a type of edible nut that comes from the kola tree, which is native to West Africa. These trees can grow up to 60 feet tall and are notable for their vibrant yellow flowers and star-shaped fruits, each of which contains two to five kola nuts.

These healthy nuts are high in caffeine and often used as an herbal supplement and natural food flavoring. The kola nut taste is initially very bitter, but it becomes sweeter when chewed.

The nuts can be dried, giving them a much more mild flavor and nutmeg-like aroma.

Keep in mind that the kola nut should not be confused with gotu kola or bitter kola, also known as Garcinia kola.

Like the kola nut, these two plants are known for their medicinal properties and have been used to treat a variety of ailments. However, despite having similar names, they are unrelated and belong to completely different species of plants.

Types/varieties

Kola nuts are very common throughout West Africa and often consumed fresh or dried for a quick burst of caffeine. Red and white kola are the two main varieties, each of which is produced by the same plant species and sometimes even found within the same pod.

These nuts also play a central role in many cultures and traditions. In a kola nut Igbo ceremony, for example, the nut is presented to welcome visitors and used to symbolize peace and goodwill.

In other parts of the world, kola nut extract and kola nut powder are much more common than the fresh nut itself. These ingredients are found in many sodas, energy drinks, weight loss drugs and herbal supplements.

In addition to bumping up the caffeine content of these products, the nuts also provide a unique taste and aroma.

Health benefits

Rich in caffeine, theobromine and disease-fighting antioxidants, the kola nut has been linked to a number of powerful benefits. Here are a few of the ways that this healthy nut could impact your health.

1. Enhances energy levels

Kola nuts are high in caffeine, a compound found in coffee and tea that acts as a central nervous stimulant. Caffeine alters the activity of certain neurotransmitters in the brain, leading to increased energy levels, focus and alertness.

What’s more, studies even have shown that moderate amounts of caffeine could also enhance endurance, brain function and mood while decreasing the perception of fatigue.

2. May promote weight loss

Thanks primarily to its caffeine content, some research has suggested that the kola nut could potentially help ramp up weight loss. This is because caffeine has been shown to increase metabolism by bumping up the amount of calories burned throughout the day.

It may also help decrease energy intake, which could also be beneficial for weight loss.

A 2002 study published in the International Journal of Obesity and Related Metabolic Disorders examined the effects of an herbal supplement with kola nut on weight loss. In this six-month randomized, double-blind, placebo-controlled trial, 167 people were divided into taking a placebo or the herbal treatment for six months.

After six months, the kola nut supplementation group had greater weight loss and lost more body fat, not to mention saw a decrease in LDL cholesterol and increase in HDL cholesterol compared to the placebo group. This led researchers to conclude that the kola nut supplement promoted weight and fat loss and improved lipid profiles.

3. Could help treat migraines

Caffeine has long been used as a natural remedy to provide quick relief from headaches and migraines. It works by constricting blood vessels in the brain, which can decrease blood flow and reduce pain.

According to a review in the Journal of Headache and Pain, combining caffeine with over-the-counter medications like aspirin or ibuprofen significantly improved symptoms of migraines and tension headaches compared to medications alone.

Historically, kola nuts have been used to treat migraines and headaches, along with many other conditions ranging from morning sickness to indigestion. However, more scientific studies are needed to evaluate the effects of the kola nut and whether or not it can treat or prevent headaches.

4. Helps stabilize blood sugar

Several recent studies have focused on the potential relationship between the kola nut and diabetes. According to a 2019 animal model published in the Journal of Ethnopharmacology, kola nut extract was found to have powerful anti-diabetic properties and was able to decrease blood sugar levels when administered to rats.

Not only that, but treatment with kola nut extract was also able to improve the function of beta cells in the pancreas, which are responsible for the production of insulin.

Kola nuts are also rich in caffeine, which may be beneficial for balancing blood sugar levels. One massive review in Archives of Internal Medicine even found that each cup of coffee consumed per day was associated with a 7 percent lower risk of developing type 2 diabetes.

However, more research on humans is needed to confirm the anti-diabetic effects of kola nut.

5. May block growth of bacteria

Some research has found that the kola nut could possess potent antibacterial properties, which could potentially help prevent the growth of harmful, disease-causing pathogens.

For instance, one in vitro study conducted in Nigeria noted that red and white kola nut extracts were effective against several strains of bacteria, including Streptococcus anginosus and Proteus vulgans, both of which can cause dangerous infections in humans.

Uses

What foods contain kola nut, and how can you start incorporating it into your diet? Depending on where you live, you may have a hard time finding fresh kola nuts for sale at your local supermarket.

Certain online retailers and specialty shops may carry them, but they are often more widely available in powder, capsule or tincture form instead.

Try mixing powdered varieties into yogurt, smoothies or cereals for a kick of caffeine and antioxidants. Alternatively, you can use it to brew kola nut tea by combining one teaspoon with a cup of hot water and steeping for a few minutes to taste.

Nutrition facts

Kola nuts are high in caffeine, a compound that acts as a central nervous stimulant and has been linked to a long list of potential health benefits, ranging from increased energy levels to reductions in hunger and appetite.

In addition to providing a hearty dose of caffeine in each serving, kola nuts are also high in theobromine, a chemical compound found in food sources like chocolate and tea leaves. Theobromine can dilate the blood vessels, stimulate the heart and act as a natural diuretic to promote urine production.

Kola nuts also offer a range of antioxidants and polyphenols, including catechin, epicatechin, apigenin and naringenin.

Risks and side effects

According to the U.S. Food and Drug Administration, the kola nut is generally recognized as safe for human consumption. However, although this nutritious nut can be safely consumed by most, there are a few kola nut side effects to consider as well.

Because kola nuts are high in caffeine, it’s very important to keep your intake in moderation. Not only is caffeine very addictive, but consuming high amounts can cause side effects like hyperactivity, nervousness, fidgeting and sleep problems.

It’s generally recommended to limit caffeine intake to fewer than 400 milligrams per day for most healthy adults. However, those who are pregnant should limit their caffeine consumption to fewer than 200 milligrams per day to avoid caffeine overdose.

Caffeine is also not recommended for infants, children or adolescents, as there is limited research on its safety or potential side effects.

If you have any underlying health conditions or take any medications, it’s best to consult with your doctor before making any changes to your diet or starting any new supplements.
