good whey protein grass-fed powder

I like this brand very much, not too many fillers, and it's grass fed, which tends to be higher priced than regular whey protein powders. I try to choose grass fed whey protein powders when I can afford it, because sometimes with whey powders, I can smell cow. I don't eat beef anymore, so to me, when I can smell cow in products - it's funky to me. This doesn't smell like cow, it just smells creamy.

Clean grass-fed protein powder

This unflavored whey mixes into anything without changing the taste. I add it to oatmeal or smoothies post-ride for clean protein. The grass-fed sourcing is important to me and Natural Factors does it right. Two pounds lasts me a good while even using it regularly. Dissolves better than most protein powders I've tried.

Your Basic Whey

Huge fan of Natural Factors' products. I usually get their flavored whey, but it was out of stock. This unflavored product was fine, but I would prefer to mix in a smoothie to add some taste. The ingredients are basic whey, which is great since I don't want a bunch of extra stuff mixed in. The size of the container is huge so it will last a while. This product is great to take post-workout or dieting (helps to feel full).

Too bad I’m lactose intolerant

Natural Factors is always good, ingredients are pure, and packaging is always good. This whey protein is comparable to the sports brands types with the difference that it offers unflavoured. A good reliable clean formulation for those who aren’t lactose intolerant. I am, so I can’t high load this stuff.

my favorite whey protein

High quality, good taste (unflavored, but no weird after taste), grass fed. Mixes well into shakes - great after workouts or for a quick, light snack or meal. This has been my go-to for years. So glad iHerb carries it - and at a good price to boot.

My favorite protein

When I take this whey , I feel safe. It has normal taste with no chemicals, which I like. I guess I could say it is high quality product. And it also feels good on my stomach. I tried so many brands and I came to realization that Id rather have my protein with less flavors than add all the chemicals to my body. At the end I workout to be more healthy.
