Here's the quick version if you're short on time...

If you don't have a noticeable intolerance to lactose, you have no current medical concerns and you aren't about to step on a bodybuilding stage, it really doesn't matter and either will be a great protein addition to your day!

Okay, let's get into some frequently asked questions for you aficionados still reading! 

Is WPI a better protein than WPC?

WPI and WPC are made from the same source of protein, whey protein across the board has an incredibly good amino acid profile. The only difference between WPI and WPC is the amount of production, WPI is more processed to remove additional carbohydrate and fat and therefore has more protein.

Which tastes better, WPI or WPC?

Boomers WPI and WPC are both flavourless protein powders, meaning if you put it into anything with a flavour you will not know it's in there at all. As WPC has slightly more fat and carbohydrate it provides a slightly creamier texture, it's the equivalent of Hi-Lo vs Full Cream milk.

Why is WPC cheaper?

Because it has a shorter production process, the less that is done to the product the cheaper the output. We often reference WPC as a better value product because overall it is 5.3c per gram of protein and WPI is 7c per gram of protein.

Doesn't WPI have more protein, which is better?

WPI has more protein per serving, but that is only if you compare a flat scoop of WPI and a flat scoop of WPC. In that case, yes it does, by 2.6g per serving.

But if you take a step back and look at a comparison: if you have a flat scoop of WPI or a slightly heaped scoop of WPC you'd get the same amount of protein for around 20 more calories.

WPC has more fat, so isn't it going to make me put on weight?

No, your weight changing will only be effected if you significantly adjust your overall calorie intake. After all, weight change ultimately comes down to how many calories you intake compared to how many calories your body uses each day.

If you have a scoop of WPI instead of WPC, you will be saving 11 calories. Your whey protein of choice is not the place to be making these kind of changes.

Why would companies push me towards a WPI supplement?

Most protein powder companies push WPI much more than WPC, but we believe it has unnecessary clout in the fitness industry specifically. It's one of the biggest 'if it's repeated enough, it becomes truth' statements out there that is too simply washed away with the response "because it has more protein?". Yes, it does have more protein but in the grand scheme of your diet 2.6g of protein really isn't moving the needle too much, and if you want more protein then have a heaped scoop and the end result is cheaper by grams of protein for a minimal amount of calories.

Okay, so why might WPI be a better choice?

There are a few scenarios where WPI is objectively a better choice for you:

1. Your health professional has recommended it for you specifically, this could be for a multitude of reasons, so ask them!
2. You are very lactose sensitive, both WPI and WPC have lactose but WPI has less. Especially if you are drinking it on an empty stomach without many other ingredients this can upset lactose sensitive tummy's.
3. You are extremely anal about your current macronutrient intake, as in you're a bikini competitor about to step on stage. If you take WPI because of the fewer calories and then drive through McDonalds on the way home you're focussing on the wrong improvements.
4. Money is of zero concern, and you just want the higher protein per bag option. Because again, you could just have a larger scoop to get the same protein but the bag would run out slightly quicker.

Is there any scenarios where WPC is a better choice?

There are a few scenarios where WPC is objectively a better choice for you:

1. Elderly populations looking for a more well rounded supplement, although this will still be more impacted by what you mix the protein with.
2. Those looking for a creamier protein source, compared to WPI.
2. Those looking for the best value whey protein option.
