[Costco] Leanfit Sport Protein Isolate & Collagen 2 Kg 39.97

Leanfit Sport Protein Isolate & Collagen for $39.97, normally $62. I believe .97 indicates this is a clearance price.

This is only in store, not sold online.

Great price indeed. Which location did you see this at?

I've had prob 40+ protein flavors in my life, across several brands. This is by far the worst, it was the first time I couldn't finish a shake. I actually returned it after trying it, the first time I've ever returned a consumable product.

I know some people are fine with it, but I def couldn't deal with 2kg of that.

I haven’t tried too many flavours but this one doesn’t taste too different then the Kaizen protein Costco used to carry years ago, but then again I do mix in banana and blueberries so perhaps that masks the flavour.

Saw this today at Costco Oshawa North as well but didn't get it as had the other isolate Costco carries and I prefer chocolate flavor.. This is only in vanilla flavor but the added collagen is a good additive. Also I read the reviews about this one clumping and not being mixable in blender bottle.. It's a good deal though if you need protein.

I will never buy this powder again. Regardless of price. Flavour was OK but too much sweetener and that collagen!! Did not mix well.

I don't get it, what's the appeal of collagen? It's an incomplete [no tryptophan] trash protein...?
We should have crowd-bro-funded Kaizen debt instruments [paying their coupon or a convertible preferred share dividend in 2 kg tubs], I didn't even know they were in trouble...

For $39 it’s a yes. Flavour was sweet, but wasn’t worst in the world.

Well, collagen is needed for your skin and many other organs. Dr Rhonda Patrick adds some in her morning smoothy (at leats used to) and Dr Brad Stanfield does it too. Both produce informative youtube videos. I think its in hopes of helping slowing skin aging usually.

"The evidence from the reviewed studies suggested that both collagen supplements improve skin moisture, elasticity, and hydration when orally administered. Additionally, collagen reduces the wrinkling and roughness of the skin, and existing studies have not found any side effects of its oral supplements." https://www.ncbi.nlm.nih.gov/pmc/articl ... upplements.

Anything pertaining the bowels, we mostly dont know. But personnally, I take some collagen in hopes it helps maintaining the lining of my digestive system. I will be ok if it only maintains my skin.

Agree with a few of the posters here - I worked through a bag of this stuff about 4 months ago. It’s bearable, but likely the worst protein powder I’ve had in 10+ years of working out. It mixed poorly when mixing with water or milk, and it tastes overly sweet / cloying.

My gauge of a protein powder is usually how it mixes and how palatable it is when mixed with water. This powder failed on both fronts. But I’m cheap and I finished the bag haha

Collagen has a large amount of hydroxyproline, which isn't packed in other foods. There is some evidence that it does support skin, joint and connective tissue health above people who don't consume collagen.

https://www.todaysdietitian.com/newarch ... 9p26.shtml

I'm skeptical as the research is still limited, may be somewhat indicative of protein intake benefits in general and there's likely a moral hazard (some of these will be funded by the industry), but it's honestly promising. Symptomatic joint pain improved over placebo, skin health improved via biopsy, etc.

Does this mean I'll be chugging bone broth and snorting collagen powder? No, but if someone wants to add it to a good quality, complete protein powder without it being super expensive then sure.

Don't forget about what damages collagen! Smoking and other substances, lack of sleep, high sugar intake (it binds to collagen and permanently rips it up), acture or chronic injury, UV radiation, etc.

Ironic that the people that called me insane for buying unflavoured whey find this stuff too sweet, and I don’t mind it. Fwiw, I tend to dial back all flavoured protein by mixing one scoop flavoured with one unflavoured.

FYI 10g of collagen per day (this has 10g per scoop) can increase the risk of kidney stones.

"One potential concern is that collagen (in dosages of around 10 grams per day) has been shown to increase oxalate levels in urine, likely because collagen consists of approximately 10% hydroxyproline, and a major metabolite of hydroxyproline is oxalate. As a result, higher doses of CII could increase the risk of oxalate-based kidney stones in susceptible individuals."

Also the 10g of collagen is very poor quality protein. From the same source "CII should not be taken as a protein supplement because it has a lackluster amino acid profile."

Source: https://examine.com/supplements/type-ii-collagen/

For me personally, the product is not worth the risk of kidney stones.

Is the flavor the same as the non-collagen Leanfit powder?

Hmm the thing with hydroxyproline is that your body can manufacture it, if there is a need, using other amino acids. There is no way for our bodies to construct tryptophan. Tissue production/muscle growth is going to be limited to the 8 amino acids.
It would be better just have complete protein in this shake (and not have volume wasted by collagen depending how much is in there), and I'd eat non-sugared Jello or bone broth from collagen. Should be dirt cheap coming from bones. I think these studies can make sense in absence of general protein supplementation, for those specific use cases, but you would definitely be getting all amino acids (especially the 8 that we can't manufacture) from a complete source like whey.
Weird marketing trend...People would pay for dilution of the good stuff.
