How Much Caffeine In Kirkland Diet Green Tea? Many people choose to drink diet green tea as a result of its lower caffeine content.
Some also like the taste and do not find it as bitter as regular green tea (source). Most forms of green tea contain about 25mg of caffeine per 8 oz cup.
This is quite low compared with coffee which typically contains around 100 mg of caffeine per cup.
However, caffeine is not the only substance in green tea which may provide health benefits. Catechins are also present, and these substances are helpful in many ways (source).
Some studies indicate that catechins may work with caffeine to provide even greater benefits. However, it should be noted that no clear evidence of this has been shown in humans.

What is Kirkland Diet Green Tea?
Kirkland Diet Green Tea is a product of the Kirkland Signature company. This is a division of Costco that manufactures various products, from food to household goods.
The drink contains green tea, which is naturally caffeinated and sweetened with sucralose. Each bottle contains 20 fluid ounces or 591 ml of liquid.
How Much Caffeine In Kirkland Diet Green Tea?
Each bottle of Kirkland diet green tea contains 150mg of caffeine. This is almost as much as a can of cola, typically around 70 mg per 8 oz (source).
However, it should be noted that these two drinks are not equivalent. Cola is quite unhealthy for you due to its high sugar content.
It also lacks many benefits of green tea, such as the catechins and antioxidants that help your body fight against disease (source).
For this reason, it may not be a good idea to use cola to replace green tea, which has less caffeine and more beneficial compounds.
It should be noted that caffeine is also present in decaffeinated green tea products. These typically contain around 10mg of caffeine per cup, similar to what one can find in a slice of chocolate cake (source).
What are the Benefits of Kirkland Diet Green Tea?
Green tea has been shown to provide several health benefits. These include reduced risk of heart disease, some types of cancer, and Type II diabetes (source).
It also has many anti-oxidant effects that help prevent various forms of cell damage, especially the damage caused by free radicals (source).
Scientists are not entirely sure how green tea works to provide these benefits. However, they believe that catechins and caffeine work together to aid this process (source).
Is Kirkland Diet Green Tea a Good Deal?
Kirkland Diet Green Tea can be purchased at Costco for around $2 per bottle. This makes it cheaper than many other brands of green tea.
A 20 oz bottle usually lasts around 7-10 days when consumed by one person. Therefore, the daily cost is about $0.30-$0.40 (source).
This is quite a good deal considering that many green teas can cost double or triple this price (source).
For this reason, Kirkland Diet Green Tea is an affordable option with many health benefits.
However, it should be noted that decaffeinated green tea products are also available at Costco, and these typically cost around $0.20 per cup (source).
It can be difficult to determine exactly how much caffeine is in Kirkland Diet Green Tea since the bottle does not list this information.
However, the product’s caffeine content is not very high compared with other green tea or caffeinated drinks such as coffee and cola.
Kirkland Diet Green Tea is Good For Pregnant Women?
Kirkland Diet Green Tea may provide health benefits for pregnant women. In particular, in one study, green tea was shown to help reduce the risk of miscarriage by 42% (source).
However, it should be noted that this research was not performed on decaffeinated green tea. Therefore, a lower caffeine content product such as Kirkland decaffeinated green tea may be more appropriate.
Moreover, it should be noted that decaffeinated green tea products are also available at Costco, and these typically cost around $0.20 per cup (source).
For this reason, Kirkland Diet Green Tea is an affordable option that provides many health benefits for pregnant women.
Does Kirkland Diet Green Tea Help in Weight Loss?
Kirkland Diet Green Tea does not appear to impact weight loss significantly. One study on mice showed that green tea did not affect weight gain after feeding the mice a high-fat diet (source).
However, this research was performed using decaffeinated green tea, so caffeine was likely responsible for any beneficial effects. Kirkland Diet Green Tea is decaffeinated, so it probably has no benefit in terms of weight loss.
Does Kirkland Diet Green Tea have any Side Effects?
Kirkland Diet Green Tea does not appear to have any major side effects. However, it should be noted that green tea may reduce iron absorption (source).
In addition, it may have a diuretic effect and contribute to dehydration (source). For this reason, Kirkland Diet Green Tea should not be consumed excessively by pregnant women or individuals with kidney problems.
