Our best-selling Rule 1 Whey Blend flavours over the last 12 months are Vanilla Ice Cream and Chocolate Fudge, close together at the top, with Chocolate Coconut in third. If you are buying R1 Whey Blend for the first time, any of those three is a safe start, and the first two also come in the better-value 5 lb tub. The ranking below is based on our own sales records, not taste opinions, so you can see what other shoppers in Australia keep coming back for.

How we counted: every R1 Whey Blend tub in our sales records from late October 2025 to late October 2026, adding up the 2 lb, 5 lb and 10 lb sizes. We left out tubs sold under a separate short-dated listing earlier in the year, which would have lifted Chocolate Coconut, Chocolate Hazelnut, Chocolate Biscuit and Cinnamon Swirl, and a batch of older sales where no flavour was recorded. Stock changes often, and stock in each store varies, so check the product page or your local store before you travel.
What is in R1 Whey Blend?
Rule 1 states each serve gives 24 g of whey protein with 5 g of naturally occurring BCAAs. The protein comes from a blend of whey concentrate, isolate and hydrolysate, with no non-whey proteins, amino spiking or creamers listed. Flavour changes the scoop size and macros a little, so check the panel on the flavour you choose.
Because it contains concentrate, R1 Whey Blend has more lactose than an isolate. If regular whey upsets your stomach, R1 Protein WPI is the isolate-only option from the same brand. Our R1 Whey Blend vs R1 Protein WPI comparison covers the differences in detail.

Prices are at the time of writing. The bigger the tub, the lower the price per pound, and every 5 lb and 10 lb tub is over $99.99, so delivery is free. If you already know your favourite, go 5 lb. If you are trying a new flavour, start with 2 lb. Afterpay is available at checkout if you would rather spread the cost of a bigger tub.
How to pick a flavour without wasting a tub
- Start with a best seller. Vanilla Ice Cream, Chocolate Fudge and Chocolate Coconut have sold the most tubs, so they are a lower-risk first buy.
- Try before you buy. Many Supps247 stores run free taste tests, so you can try a flavour before committing to a tub. Our taste before you buy guide explains how it works.
- Think about how you will use it. If you add protein to oats, smoothies or pancakes, a vanilla flavour fits more recipes than a dessert flavour.
- Mix it the way the label says. Follow the directions on your tub. Milk gives a creamier shake but adds kilojoules, while water keeps it lighter.
- Size up once you are sure. When you have finished a 2 lb tub and want more, the 5 lb tub brings the price per pound down.
Who R1 Whey Blend suits
R1 Whey Blend is an everyday whey for people who want a good-value shake after training or between meals. The ISSN protein position stand suggests 1.4 to 2.0 g of protein per kg of body weight a day for most people who exercise, so a 75 kg lifter would aim for roughly 105 to 150 g a day. One scoop covers 24 g of that. Food should still supply most of your protein, and a shake simply fills the gap on busy days.
- Good fit: building muscle on a budget, bulking or maintaining when a gram or two of extra carbs and fat per scoop makes no difference, and anyone who wants a wide choice of flavours.
- Look elsewhere: if regular whey makes you bloated, try an isolate such as R1 Protein WPI. If you have a milk allergy, whey of any kind is not suitable, so talk to your doctor and consider a plant protein.
Our pick
For most people, R1 Whey Blend 5 lb in Vanilla Ice Cream or Chocolate Fudge is the easy choice: they are our two best sellers and both come in the bigger, better-value tub at $199.95 at the time of writing. If you like coconut, Chocolate Coconut is our third best seller in the 2 lb tub. If you want the leanest Rule 1 shake, compare R1 Protein WPI 2 lb instead.

FAQs
What is the most popular Rule 1 Whey Blend flavour?
In our sales records for the last 12 months, Vanilla Ice Cream sold the most R1 Whey Blend tubs, just ahead of Chocolate Fudge, with Chocolate Coconut in third. Strawberries & Creme and Chocolate Peanut Butter were equal fourth. The ranking adds up the 2 lb, 5 lb and 10 lb sizes and leaves out short-dated stock sold under a separate listing.
How much protein is in R1 Whey Blend?
Rule 1 states each serve gives 24 g of whey protein and 5 g of naturally occurring BCAAs, from a blend of whey concentrate, isolate and hydrolysate. Scoop size and the other macros change slightly between flavours, so check the nutrition panel on the flavour you buy.
Which R1 Whey Blend flavours come in a 5 lb tub?
When we checked, the 5 lb tub was in stock in Vanilla Ice Cream, Chocolate Fudge, Chocolate Peanut Butter, Cookies & Creme, Strawberries & Creme, Milk Chocolate, Cafe Mocha, Fruity Cereal and several others. Chocolate Coconut, Chocolate Hazelnut and Chocolate Biscuit were 2 lb only. Stock changes often, so check the product page for the current list.
Can I try R1 Whey Blend before I buy a tub?
Yes, at stores that offer free taste tests. Ask staff in your nearest Supps247 store which flavours are open to try that day, as it varies by store. Trying first is the easiest way to avoid buying a big tub of a flavour you do not enjoy. Use our store locator to find a store near you.
Is R1 Whey Blend lactose free?
No. R1 Whey Blend contains whey concentrate, which keeps more of the milk's lactose than isolate. Many people handle it fine, but if regular whey makes you bloated, an isolate such as R1 Protein WPI is lower in lactose, though still not lactose free. If you have a milk allergy or diagnosed intolerance, check with your doctor or dietitian first.
