Whey protein isolate is my go too. Wa nice because only high end good companies made it in a handful of flavors so I never really had to think hard about getting a “good one” Now that ghost and ABE make it also now I need to actually check it first. Myprotein and isopure were the go to’s always though.
Yeah, they changed the ingredients. The vanilla is overly salty now and strange tasting. I returned it.
I use the Isopure whey unflavored protein also. One scoop in a bowl with nonfat plain Greek yogurt and one tablespoon SF pudding mix. Top with berries (if you defrost frozen berries a bit, the juices are kind of like a syrupy sauce too). I also use the Quest Cinnamon Toast Crunch protein powder in baked goods. My favorite is to make a pumpkin soufflé.
If you want something that dissolves easily in hot or cold coffee, a whey protein isolate is usually your best bet. It tends to mix smoothly and clump less than concentrate or casein. If you truly love your coffee black and want as little flavor change as possible, there are unflavored isolates like Isopure Unflavored Whey Isolate or Naked Whey Unflavored that blend in without adding sweetness or creaminess. If you’re open to a slight flavor boost, there are some great coffee-specific proteins (I like using ON Mocha Cappuccino) that pair well with coffee without overpowering it. I’ve been using another Reddit user’s [deep dive on protein powders](https://www.reddit.com/user/Industrious_Bradly1/comments/1mv97y1/comparing_protein_powders_by_brand/) that I found. It lists the type of protein, flavor, and even price per scoop. If you’re still looking, I recommend you check it out.
Seconding Isopure! Their unflavored whey is excellent
Isopure because it has the best macros and I’m putting into things with flavor, since alone, it’s not flavored. PB Greek Yogurt bowl, ninja creami recipes, berry smoothies, pancake batter.
Thanks for that call out. I didn’t realize the Costco version was flavored. Bummer. This is the version I use, for anyone interested. https://a.co/d/gyAhnoP
Isopure zero carb. I think the scoops are only like 29g weight with 25g protein
I always have Isopure UNFLAVORED whey on-hand. I either drink that plain, or often times use it to "dilute" the overly-sweet flavored proteins. The flavored proteins I have just depends on my mood and what I feel like buying at the time, but the Isopure unflavored is a staple that I always have. No added bullshit - just whey isolate. Mix it into literally whatever you want.
My A-1 go-to choice is UNFLAVORED Isopure whey. There’s no bullshit flavorings or sweeteners - just protein. You can add whatever flavors YOU want. Lots of flavored powders are WAY over-sweet and cause me to burn-out on their flavors. I do keep a few other flavored powders on-hand, but when I use them I cut them heavily with the plain Isopure to dilute the sickly-sweetness. So, I keep a jumbo 5-pound tub of the Isopure, and then I rotate through smaller sizes of various flavored mixes that I use occasionally as mix-ins.
Isopure non-flavored. Can add that shit to anything. All the flavored ones are too sweet and get tiresome over time. I'll still buy various flavored protein powders, but I \*always\* cut them with the unflavored Isopure. Otherwise, I just mix the Isopure with whatever I want to get whatever flavor I like (most of the time, I mix it with matcha tea).
Same for Isopure unflavored whey isolate. Its just whey protein and lecithin as an emulsifier. You're not going to get much more protein density than that. I don't mind the taste of the unflavored stuff. In fact, I'd rather have unflavored whey mixed with nothing but water than any of these sickly-sweet flavored protein powders. If I used a flavored protein powder, I always cut it with the unflavored stuff so I don't feel like I'm trying to drink and entire liquified cake, which makes me want to gag. The unflavored stuff doesn't taste like much at all. Maybe a faint "milky" flavor, but that's about it. Very easy to just chug it down.
>Best protein to calorie ratio is Transparent Labs. Nah, the best they have is [120 calories for 28g of protein](https://www.vitaminshoppe.com/p/transparent-labs-proteinseries-french-vanilla-955-g-powder/tpl-11535) (4.57 calories per g of protein). [Isopure Vanilla](https://www.vitaminshoppe.com/p/nature-best-isopure-isopure-zero-carb-vanilla-3-lb-powder/np-1098) is 100 calories for 25g of protein (4 calories per g of protein).
[Isopure Vanilla](https://www.vitaminshoppe.com/p/nature-best-isopure-isopure-zero-carb-vanilla-3-lb-powder/np-1098). It has the best calorie/protein ratio I've seen
