Based on 1 year's data from Mar 20, 2026 How it works
Used to be lean fit sport the one in the dark blue bag. It has some pretty good macros, doesn't taste that great though and it mixes only decently with a shaker bottle.
The best was Kaizen way back in the day. Then Gourmet Whey isolate was also a good one for a while Leanfit now has unflavoured whey isolate. I personally prefer unflavoured so I can flavour it to my liking and also use it for ice cream with my own sweetener of choice (I get me that sweet allulose from Trump land) Seems like a no brainer if you can get it on sale
I liked the leanfit stuff. I used to stock up when it went on sale.
A little high in cholesterol, but otherwise very clean.
Very glad to hear this. Leanfit is my brand
Same itβs great value
If you shop at Costco, have you tried Leanfit? They are Canadian, and when it's on sale, it's by far the cheapest protein you can get. It tastes ok, but I don't find any protein powders are particularly great for taste.
Leanfit protein is absolutely disgusting mixability/texture. It foams up so much. I hate that protein. I only buy Optimum Nutrition at Costco, it mixes perfect every time and has the best flavors/taste imo. I usually stock up with about 4-5 bags whenever I see it on sale. If I dont drink it all I sell bags on facebook marketplace. Ez profit because they are extremely expensive if you buy elsewhere. EDIT: Hes asking for opinions on Costco protein. I gave my opinion and im being downvoted LOL. ON Gold Standard > Leanfit in my opinion.
Yeah I noticed that... wtf. How do so many people here like lean fit. Like objectively the mixability was just bad. I challenge anyone to do a comparison with just water and powder Leanfit vs ON gold standard and can easily see the difference in texture and mixability is way worse on lean fit. It foams up so much and the foam doesnt even go away. Also in a blender it has weird texture too. I think they havent tried the premium Optimum Nutrition protein, its on another level.
Leanfit is fine if you really cant afford the better stuff but the amount of people Ive seen say it makes them bloated says it's pretty cheap ingredients. Also if you try leanfit and gold standard you will notice a taste and texture difference that is really hard to get past.
You get downvoted cause for whatever reason this sub is full of lean fit pushers even tho its a massively sub par product.
I found it was gross too.
