Grass Fed Whey Protein Isolate

Grass Fed Whey Protein Isolate

Our grass fed whey protein gives your body the building blocks needed for optimal recovery. When your body doesn’t get enough protein, you feel weak and lethargic. Preserve your strength and energy by getting enough daily protein.

Sunflower Lecithin

Sunflower Lecithin

Many whey protein powders and plant based proteins have a tendency to clump in liquids. To make sure our protein mixes easily in both hot and cold drinks we instantize the power with a small amount of lecithin from non-gmo sunflower.

Frequently asked questions

Answers, minus the fluff.

It is whey protein that comes from milk produced by cows that eat grass as their primary diet.
Absolutely. It’s great in pancakes, muffins, bread, and many other recipes.

It has a slight milky taste when mixed with water and is hardly noticeable when mixed into other drinks or recipes. If you're looking for flavored whey protein try our chocolate protein or iced coffee protein.
Our whey mixes easily into your drinks and recipes. It’s been mixed with a small amount of sunflower lecithin. This reduces the grittiness and allows it to mix quickly.
Grass is a natural food source for cows. Annually, on average 85% of our cows’ diet is grass. Our cows can graze naturally outdoors on the grass of open pastures, as nature intended. On average, they spend 90% of their time outside on pasture during the year. They are free to roam around paddocks and exhibit natural behaviors. Our cows are happy and contented, and we are internationally recognized for our high standards of animal welfare.
Yes, our whey protein is free of hormones and antibiotics.
Yes, our whey protein is tested for heavy metals. Please emailinfo@opportuniteas.comto get a copy of the latest testing results for yourself.
Our unflavored whey has zero flavorings or sweeteners. It’s pure protein.
There are so many ways to use whey protein. You can mix it with water or milk and have a shake. You can also add it to your coffee, tea, or juice. Blend it in a smoothie. Mix it in your baking recipes. Try it with yogurt or oatmeal. You can mix whey protein with almost any drink or recipe.
You don't need protein powder if you get enough protein from your typical diet. Natural foods such as eggs, chicken, beef, pork, beans, fish, milk, and many more foods contain significant sources of protein. However, if you don't get enough protein from your usual diet or if you don't feel like eating meat, protein powder is a very convenient way to meet your daily protein requirements.

The differences in color and texture you've noticed are normal and reflect the natural variation in our grass-fed whey isolate protein. Since this whey comes from cows that graze on grass year-round, their diet changes with the seasons, which can affect the whey's color, texture, and even subtle aspects of its flavor. These variations are a characteristic of an all-natural, grass-fed product and contribute to its uniqueness.
