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.

Grass Fed & No Addictive

Reorder many times as I drink this daily post training workout and for maintaining fitness. Great quality of whey protein as it’s grass fed. Appreciate the ingredient is pure without addictive. It’s a great supplement for those who can’t get enough protein from eating so much meat.

Seems good

I can't say I have noticed any particular benefits from this product yet, but I like that is produced from grass fed cows and the brand is reputable. It tastes fine and dissolves well into shakes. I tried to look for a whey protein that contains less heavy metals and I trust this one.

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.

Grass Fed Whey

I get this whey for my husband. He likes the flavor when he drinks immediately. If it sits for a while the taste changes. It mixes well with water. I like that it's sourced from grass fed cows and has no added sugars. All natural ingredients without the use of chemicals.

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.
