10 Disadvantages Of Coconut Water You Should Be Aware Of
Watch out for the ill effects this tropical drink can have if consumed in excess.
Coconut water is known as the ‘Magic Drink’ or ‘Nature’s Drink’ due to its countless health benefits. However, a few disadvantages of coconut water might make you reconsider consuming it.
Overconsumption of coconut water may lower your blood pressure, cause an electrolyte imbalance, or act as a laxative. Consequently, it is important to be aware of all the effects of overindulging in this beverage.
This article examines the side effects of coconut water. Take a look below.
Disadvantages of Drinking Too Much Coconut Water
Drinking too much coconut water may cause several adverse effects. Melissa Hooper, Registered Dietitian and Nutritionist, says, “The extra calories from the sugar could contribute to weight gain if they are not balanced out with other foods and drinks consumed throughout the day. The natural sugar content can also lead to dental caries if you are not diligent in brushing your teeth daily. Also, due to its natural sugar content, if you have diabetes, drinking excess coconut water could lead to increased blood sugar levels.”
1. May Lead To Diarrhea
Too much coconut water consumption can be dangerous. Drinking too much of it can have laxative effects on your digestive system (1). Since coconut water is a natural laxative, it might not be suitable for some people who have problems with their bowel movements. Hence, care should be taken before consuming a large amount of coconut water.
2. Is Not The Ideal Drink For Athletes
In case you prefer coconut water for rehydration immediately post-workout, you should opt for plain water instead. This is because the amount of sodium plain water contains is unarguably more than that present in coconut water. And hey, it is sodium that aids rehydration, right?
Also, when compared with certain sports energy drinks, coconut water is way low in carbohydrate content. Coconut water just contains one-tenth the sodium when compared with other sports drinks (2).
2. May Not Be Good For People Vulnerable To Allergies
Some of us do have allergies. We might be allergic to certain food items and ingredients and hence, we refrain from consuming them. Similarly, coconut water might cause allergic reactions in certain people who are allergic to it.
Coconut is basically a tree nut. Hence, certain people who consume coconut water might be prone to tree nut allergies as well as other forms of allergy. Coconut water should be kept away from people who are prone to allergies (3).
4. Possesses Diuretic Properties
This is another disadvantage when you consume too much coconut water. Coconut water has diuretic properties (1). This means too much of its consumption might require you to take a break and visit the loo a number of times. Although a mild amount of coconut water has hydrating properties, too much of its consumption can be unhealthy.
Melissa Hooper says, “Drinking coconut water at night could elevate blood sugar for people who have diabetes and increase urination, disturbing their sleep due to the constant need to make trips to the bathroom overnight.”
5. Might Cause Electrolyte Imbalance
The high potassium content of coconut water is one reason it is a wonder drink. But then, the very same reason can make coconut water fatal if consumed in excess.
In a specific case, a man had spent an entire day playing tennis in 90 degree Fahrenheit weather. He happened to consume a whopping 88 ounces of coconut water, which resulted in a condition called hyperkalemia, eventually leading to a serious condition (4).
Hyperkalemia causes weakness and lightheadedness, and within minutes the victim might lose his consciousness.
6. May Increase Blood Sugar Levels In Some
Coconut water may not fall under sugary drinks but still it does contain carbohydrates and calories. People with high blood sugar should not drink more than 1 glass a day. However, more research is warranted in this regard.
Also, going for immature green coconuts is better for those with diabetes than the matured ones.
7. May Lower Your Blood Pressure Too Much
Coconut water might lower your blood pressure (5). In case you are already taking medications for high blood pressure, it might cause your blood pressure to drop further down. Hence, remember to consult your healthcare provider in such a situation.
8. Might Affect Individuals With Kidney Issues
Those with chronic kidney disease (CKD) are recommended to avoid intake of coconut water. The substantial potassium content in the water may cause hyperkalemia, a potentially fatal condition resulting from a high potassium intake in kidney patients (6). It may reduce ion excretion via the kidneys. It may also interfere with drugs used to slow the progression of CKD or those taken to manage its concomitant conditions, such as diabetes mellitus and heart failure. The likelihood of experiencing sudden death and irregularities in heartbeats also increases (7).
9. Might Cause Flaccid Paralysis
Excessive intake of king coconut water was reported to cause acute flaccid paralysis in an elderly patient. He experienced weakness in his limbs and was unable to walk. Closer inspection revealed kidney dysfunction and high potassium levels (8). Thus, although uncommon, coconut water may cause paralysis in some people.
10. Might Lead To Fatal 3-Nitropropionic Acid Poisoning
Coconuts may be contaminated with the fungus Arthrinium saccharicola, which may lead to life-threatening symptoms. An elderly patient from Denmark experienced sweating, nausea, and vomiting followed by a reduced mental state with confusion, dystonia (involuntary muscle contractions), and poor balance after consuming coconut water. He fell seriously ill, developed encephalopathy (reduction in brain functioning due to toxins), and went into a coma. Subsequently, the condition was shown to be caused by high 3-nitropropionic acid levels in coconut water caused by the fungal contamination. The coconut had been kept on the kitchen table for a month after being purchased, despite the fact that it should have been stored at 4°C to 5°C in the refrigerator (9). Thus, avoid such situations by properly storing your coconuts and coconut water.
If the patient had drunk the coconut water fresh, this situation might not have occurred. This brings us to a crucial aspect that needs to be noted by everyone: Coconut water is to be consumed fresh 10). It should ideally be consumed right after cutting the fruit open.
If it is left open for some time, it may lose some of its beneficial nutrients. Coconut water is a wonder drink, yes. It might have many benefits which are virtually absent in other drinks. And talking in terms of health, it probably is the most preferred drink.
But that doesn’t mean you can become a sole survivor of coconut water, does it?

Coconut water is a refreshing, hydrating drink. However, if consumed in excess, it can lead to many adverse effects. These include electrolyte imbalances to elevated blood sugar levels. Its diuretic and laxative effects may also cause abdominal discomfort or urination difficulties. Coconut is closely related to tree nuts. Hence, it may cause allergic reactions in individuals sensitive to them. Such individuals must exercise caution and avoid drinking coconut water.
Frequently Asked Questions
Does coconut water increase sperm?
Melissa Hooper, RDN, says, “According to research, undiluted coconut water has been shown to increase sperm amount, quality, and motility with continuous consumption, at least for greater than 20 days. Increased sperm quality is due to the high amount of zinc that the coconut water has naturally. Zinc is essential in sperm formation, and therefore, consuming enough zinc will have a positive effect on sperm. Research also showed that coconut water didn’t disturb the pH of sperm, which helps to increase motility.”
