Someone told you to eat more protein.
Maybe it was a coach. Maybe a fitness influencer on IG. Maybe you read it somewhere and it made sense — you’re in your 40s, you’re trying to build strength, and apparently protein is a big part of that.
If you’re like me, you have stood at Supplement King, Costco, or Homesteader Health and felt very confused. And in the back of your mind, you’ve thought: is this just another thing fitness people are trying to sell me?
It’s a fair question. I’ll try to answer this in a way that makes sense.
WHY IT MATTERS
After 40, your body becomes less efficient at using the protein you eat. This isn’t a scare tactic — it’s just biology. Muscle tissue starts to break down faster than it rebuilds, and the process that used to happen automatically now requires a bit more input from you.
What that means practically: if you’re training to feel stronger, move better, and keep up with your actual life (hiking, carrying things, not getting winded), protein is the raw material your body needs to make that happen.
Most active women in their 40s need somewhere between 100–130g of protein per day. If you’ve never tracked that before, you might be surprised at how far below that you’re sitting. A chicken breast has about 30g. Two eggs have about 12g. A cup of Greek yogurt has maybe 15–17g. The gap adds up.
Protein powder is a practical, convenient way to close the gap on the days when real food doesn’t cover it.
DO YOU ACTUALLY NEED IT?
Only if you’re struggling to hit your protein targets through food alone.
If your mornings are rushed, if you’re not hungry right after a workout, if you’re managing a schedule where sitting down for a full meal isn’t always realistic — then yes, a protein powder is a genuinely helpful tool. A scoop blended with milk or water takes about 90 seconds and delivers 20–30g of protein.
It is not a replacement for real food. It’s a top-up. And for a lot of people, that top-up can make a difference to hitting your targets.
WHAT TYPE IS RIGHT FOR YOU?
Whey protein is the most well-researched option available. It digests quickly, absorbs efficiently, and has a complete amino acid profile — meaning it contains everything your body needs for muscle repair and recovery. If you tolerate dairy, this is your most practical starting point, and it tends to mix and taste the best.
Pea and rice protein blends are the go-to if dairy doesn’t agree with you. Pea protein on its own is missing a few key amino acids, but when combined with rice protein it becomes a nutritionally complete option. A quality blend works well although fitness influencers may try to convince you otherwise.
Collagen protein is something you’ll see a lot of marketing around right now. It has real benefits for joints and connective tissue, but it is not a complete protein and should not be your primary source. If your knees have been talking to you on the stairs, a quality collagen supplement alongside your protein powder isn’t a bad idea.
READ THE LABEL
You don’t need to read everything. Focus on four things:
25–30g of protein per serving. That’s the target range for meaningful muscle support. Less than 20g and you’re not getting enough to matter post-workout.
A short ingredient list. If you can’t identify most of what’s on the label, that’s a flag. The best products have five to eight ingredients, not twenty-five.
Less than 5g of sugar per serving. A gram or two for flavour is fine. Anything significantly higher in a product marketed for fitness is worth questioning.
Third-party testing certification. Look for NSF Certified for Sport, Informed Sport, or Informed Choice logos. These mean an independent lab has verified that what’s on the label is actually in the product. This is the one thing most people skip — and it’s the most important.
shop locally
At Costco in Grande Prairie, here’s what’s currently on the shelves and worth your attention:
Good Protein (Chocolate or Vanilla, 2kg / normally $80, on sale until April 5 for $64) — This one is my personal flavour favourite. It delivers 21g of protein and 7g of fibre per serving, it’s vegan, dairy-free, and made in Canada. It’s on sale until April 5 so now is a good time to try it.
Kirkland Signature Whey Protein (Vanilla, 2.45kg / ~$70) — 25g protein per serving, only 1g of sugar, made with isolate and milk protein concentrate. The straightforward, no-nonsense choice. It’s not fancy, but it hits the targets that matter and the price per serving is hard to beat.
Leanfit Sport Whey (Vanilla, 2.5kg / ~$50) — 35g protein per serving, gluten-free, and made in Canada. If you tolerate dairy and want the most protein per dollar on this list, this is it. A very solid pick.
Vega Organic Protein & SuperGreens (Vanilla, 2kg / ~$60) — 21g protein, 5g fibre, no added sugar, and plant-based. If dairy is off the table, this is your most accessible local option. Vega is a Canadian brand and this one pulls double duty with the added greens.
Oath Nutrition Clear Protein (Frosty Lemonade, ~$75) — 20g protein, only 1g of sugar. Clear proteins are a different experience entirely; they mix like a juice rather than a shake, which some people genuinely prefer, especially if the thick milky texture has kept you from sticking with protein powders before.
At Homesteader Health in Grande Prairie, you’ll find a wider selection with more variety in flavours and formulations. The tradeoff is cost. These products are quality, and if budget isn’t the limiting factor, the staff tend to be knowledgeable and can help you narrow it down based on your specific situation. Worth a visit if the Costco options don’t fit your needs.
A note on buying Canadian: Good Protein, Leanfit, Vega, and Vegan Pro are all Canadian-made. Given that Health Canada regulates supplements more strictly than many other countries, buying Canadian-made products also tends to mean better quality control and more honest labelling.
CONSIDER THE ENVIRONMENT
Packaging is really important to me. I try to avoid buying plastic tubs. Most protein powders come in plastic. Some of that plastic is recyclable; a lot of it isn’t.
Resealable pouches use significantly less material than rigid plastic tubs. Some brands are moving toward post-consumer recycled (PCR) plastics. If this matters to you like it does to me, it’s a reasonable question to ask when you’re shopping, and a factor to consider when two products are otherwise similar.
THE BOTTOM LINE
You don’t need the most expensive option. You don’t need the one your favourite Instagram account is promoting. You need the one that fits your body, your goals, and your life.
If you’re not sure how to get enough protein in your day, how to use a powder effectively, or whether your nutrition is actually set up to support the training you’re doing — that’s not a supplement store question. That’s a coach question.
