The Best Protein Powders, Bars, and Shakes for Women Over 50
RD-approved protein picks for staying strong after 50.

As a dietitian, protein is at the top of my “pay attention to” list, and getting enough becomes especially important as we age through every decade. It becomes even more important as we approach menopause and get into our 50s. Maintaining muscle and strength becomes more challenging over time, and our muscles don’t respond as strongly to smaller amounts of protein. That’s where the best protein supplements for women over 50 can help out (in coordination with a balanced, whole foods diet of course).
That’s why I’m pretty picky about the protein products I recommend, whether that’s protein powder, meal replacement shakes, or protein bars. I look for options that provide a meaningful amount of high-quality protein to support muscle. Pair adequate protein with regular resistance training, and you’re giving your muscles both the protein and the stimulus they need to stay strong.

I look beyond protein grams, too. Of course ingredients matter, but so do taste and convenience. After all, there’s not much value in buying a protein powder, bar, or shake that you don’t like or never reach for. Whether you want a powder for your morning smoothie, a bar to stash in your bag, or a shake that’s ready to head out the door, here’s what I look for before recommending one.
What to Consider
What are the different protein sources I should know about?
Protein sources differ in the types and amounts of amino acids they provide. Amino acids are the building blocks of protein, and nine are considered “essential” because your body can’t make them on its own.
Whey, which comes from milk, contains all nine essential amino acids and is naturally high in leucine, an amino acid that helps trigger muscle building and repair. Around 2.5 to 3 grams of leucine per serving is a useful target, which you’ll typically get from about 25 to 30 grams of whey protein.
For a plant-based option, soy contains all nine essential amino acids. Pea protein and plant-based blends can work well, too, although you may need a little more to get similar amounts of leucine and other essential amino acids.
Collagen doesn’t contain all nine essential amino acids, so it’s not a complete protein or optimal for supporting muscle. However, it can still add to your daily protein intake and may offer benefits for your skin, bones, and connective tissues.
What amount of protein should I look for in a protein supplement?
I generally recommend looking for about 20 to 30 grams of protein per serving. As you get older, your muscles can become less responsive to protein, a phenomenon known as anabolic resistance. Adequate, high-quality protein provides the amino acids your muscles need to build and repair.
Not every meal or snack needs to hit that range, but it’s a useful benchmark when comparing products and helps ensure you’re getting a substantial amount of protein in a single serving.
What’s the best kind of protein supplement for how I’ll use it?
Think about where and when you’re most likely to use a protein supplement to make sure it fits into your routine. Each option has its advantages:
- Protein powder: Choose powder if you want something versatile that you can mix into shakes, oatmeal, yogurt, or other meals and snacks.
- Ready-to-drink (RTD) shake: Keep one handy for work, travel, or anytime you want protein without mixing or prepping anything.
- Protein bar: Throw one in your bag when you want a portable protein option that doesn’t require any prep or refrigeration.
- Meal replacement: Reach for one when you need something more substantial in place of a meal. Look for enough calories, protein, carbohydrates, fat, and fiber to make it filling and well-rounded.
- Collagen: Consider it if you specifically want to add collagen to your routine. Unflavored powders stir well into coffee, oatmeal, smoothies, and other foods or drinks without adding much flavor.
If you’re buying a powder, think about flavor, too. If you usually mix it with water or milk, you may prefer a flavored option, while unflavored gives you more flexibility with what you add it to. Texture and mixability matter as well, especially if you’re particular about thick, gritty, or chalky shakes.
What do I need to know about third-party testing of protein supplements?
If a protein powder will be a regular part of your routine, third-party certification can offer extra reassurance about what you’re getting. Programs such as NSF Certified for Sport, Informed Sport, and Informed Choice can verify that what’s in the product matches the label and screen for certain contaminants or substances banned in sport, depending on the certification.
Protein bars, meal replacements, and some ready-to-drink shakes are regulated as conventional foods rather than dietary supplements, so these certifications may not apply.
