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:

1. It Is Not The Ideal Drink For Athletes

In case you prefer coconut water for rehydration immediately post work out, then you rather drink plain water. 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 but ten times high in potassium content. Coconut water just contains one-tenth the sodium when compared with other sports drinks (1).

2. Not 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. The understatement is coconut water should be kept away from people who are prone to allergies (2).

3. Possesses Diuretic Properties

This is another disadvantage when you consume too much of coconut water. Coconut water has diuretic properties (3).  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.

4. 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.

5. Might Act As A Laxative

Too much of coconut water consumption can be dangerous. Drinking too much of it can have laxative effects on your digestive system (3). 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.

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, consuming the immature green coconut is better for those with diabetes than the matured one.

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. Should Be Consumed Right After Cutting It Open

Coconut water is to be consumed fresh (6). It should ideally be consumed right after cutting it 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.
