 As one can see, Chocolate flavor contains the least amount of protein per serving (2 scoops, 30 grams), but it also has the best taste (which is highly individual, of course).

Ingredients also varies among the flavors and these are:

- Unflavored: Grass-fed whey protein isolate, non-GMO sunflower lecithin.

- Chocolate: Grass-fed whey protein isolate, organic cane sugar, organic raw criollo cacao, Himalayan salt, non-GMO sunflower lecithin.

- Iced Coffee: Grass-fed whey protein isolate, Colombian coffee extract, non-GMO sunflower lecithin.

Opportuniteas Grass Fed Whey Protein Isolate main ingredient is one of the puriest grass-fed whey protein isolates. Non-GMO sunflower lecithin is added to help with the mixability and although it is essentially a fat, due to the low amounts (<1%), total amount of fats are labeled as '0 grams' (and that is OK).

All three flavors mix well in the shaker bottle even when mixed with plain, cold water - plastic/metal mesh is recommended for better mixing.

After mixing, some foam is created, but is settles quickly.

opportuniteas isolate iced coffee tableOne also has to note that Iced Coffee flavor contains 80 mg of caffeine per single serving, which is great for boosting energy levels, but people sensitive to caffeine should avoid Iced Coffee flavor.

Iced Coffee flavor is excellent choice for pre-workout protein shake - it contains high quality, easily digestible whey protein that will prevent muscle breakdown during exercise, while caffeine will keep energy levels high.

Also, Iced Coffee is recommended for fruits smoothies in the morning - just mix, for example, one banana with handful of berries, add a serving of Iced Coffee grass-fed whey, add water and blend it. A quick and healthy breakfast is prepared - and don't forget that 80 mg of caffeine per single serving of this flavor!

Unflavored powder contains very low amount of carbs, fats, cholesterol and is recommended in post-workout shakes, with or without additional carbohydrate sources (like banana, pears, pure maltodextrin or glucose, etc.).

Usually Unflavored protein powders taste like sand, dirt, chalk and similar, but Opportuniteas Unflavored grass-fed whey isolate tastes relatively OK - it has almost no taste with just a weak milky aftertaste.

opportuniteas isolate chocolate tableChocolate flavor contains the least amount of protein per single serving, but IMHO, it also features the best taste. Not surprisingly since it comes with organic cane sugar and organic raw cacao :)

Note: Author of this reviews is slightly chocoholic :)

Chocolate flavor is great for daily snacks combined with low-fat and cottage cheese, some fruits that taste well when combined with chocolate (strawberries anyone?), milled full-grain oats, and similar.

Also, when you are on a diet, having low-carb protein bars can help fight cravings for sweets. But, Opportuniteas Chocolate grass-fed whey protein isolate, mixed with plain water tastes good and can also help fight cravings for sweets, chocolate included.

So, if you are on a diet and you 'must' eat chocolate bar or something similar, hit your home treadmill for quick run or power walk and satisfy your cravings with a serving of Opportuniteas Chocolate grass-fed whey ...


Long Story Short: Opportuniteas Grass Fed Whey Protein Isolate is excellent grass-fed whey protein supplement in many ways - it is GMO-free, gluten-free and contains no artificial chemicals, compounds, hormones and similar.

Unflavored and Iced Coffee flavors contain so little additional macronutrients that even people on the Keto diet can (and should) use them in order to increase daily protein intake.

Chocolate flavor contains less protein per serving, but it also tastes good and can be even used to fight cravings for sweets.

If you are looking for a high-quality, grass-fed whey isolate, consider this one.
