Protein helps keep our muscles strong as we age, among other benefits. “After 40, our needs increase due to muscle atrophy,” said Christiane Matey, MSHS, RDN, LDN, ABAAHP, a registered dietitian and founder of MINT Nutrition in Mooresville, North Carolina. “Protein drinks are a good supplement to help fill in the gaps.”
“But,” she cautioned, “they are not a great replacement for real food and real meals.” The best protein powder for women can help you get the nutrients you need when diet alone isn’t enough. The right choice depends on your needs, taste, budget, and how you plan to use it.

What is protein powder?
Protein powder is a supplement that can help you get more protein in your diet. “It is a powder containing protein from various sources such as whey and casein, soy and pea, rice and other protein sources,” said Qiao Yufei, MD, a physician with Mediway Medical in Singapore. “It can be used as a supplement to increase the daily protein intake.”
You can mix the powder with water, milk, or other drinks, or add it to foods like oatmeal and smoothies. Protein powder is not a replacement for a balanced diet, but it can be a simple way to get more protein when you need it. If you need to use protein shakes as a meal replacement due to medical restrictions or other concerns, consult with your doctor or a registered dietitian for more customized options. The best choice for you depends on your dietary needs, food preferences, and any health concerns you may have.
Why older adults can benefit from protein powder
You may associate protein powder with bodybuilders. But older adults can also benefit from adding protein to their diets. We naturally lose some muscle mass as we age. When that loss becomes significant, it may lead to a condition called sarcopenia.2 “The natural loss of muscle mass increases an older adult’s risk of fragility and falls,” said Dr. Qiao. “Protein is essential for muscle mass maintenance and recovery as well as for optimal health of the bones and other tissues.”
The American Heart Association (AHA) recommends pairing meeting your protein intake goals with strength training. The AHA stresses that strength and resistance training doesn’t need to be extreme. Strength exercises using free weights, machines, or body weight twice a week can help support muscle strength and overall health.3
Why protein matters for women
Protein matters for women at every age, but it can become even more important as they age. “Women are at risk of losing bone and muscle mass at an increased rate after menopause,” said Dr. Qiao. Changes in hormone levels may speed up this process.2
Getting enough protein can help older women maintain muscle and support health. “Protein powder helps with strength and mobility to help in day-to-day activities,” said Dr. Qiao. Matey recommends getting your protein from food first. Eggs, fish, chicken, beans, yogurt, and nuts are all good sources. If you have trouble getting enough protein from food alone, protein powder may help. That can happen if you have a smaller appetite, or if a medical condition or medication limits your diet.
Many protein powders claim to aid weight loss, improve immunity, enhance performance, or even improve cognitive function. They can contribute to those goals but certainly do not replace a healthy lifestyle and diet. Protein drinks are a good supplement to help fill in the gaps; they are not a great replacement for real food and real meals.”
—Christiane Matey, registered dietitian
What to look for when choosing a protein powder for women
Protein powders vary widely. Some come from milk products, while others use plant-based sources. Products also vary in protein content, other ingredients, and taste. The best choice depends on your diet, health needs, and personal preferences.
When shopping for a protein powder, look beyond the label claims. Check the protein per serving and the full ingredient list. Also look for third-party quality testing. If you have a health condition or take medication, ask your health care provider whether a protein supplement is right for you.
Type of protein powder
Protein powders come from both animal and plant sources. Whey and casein come from milk, and some powders use beef protein. You may also hear about “grass-fed” protein. Researchers have compared protein from grass-fed and grain-fed animals, but it’s unclear whether one offers greater health benefits over the other.1 Plant-based options may contain soy, pea, rice, hemp, or other plant proteins. If you avoid dairy, a plant-based powder may be a better fit. If you have trouble digesting lactose, check the label carefully. Some whey powders may cause digestive issues.
Protein per serving
Check how much protein each serving provides. “Products should contain 15 to 25 grams of protein per serving,” Dr. Qiao said. This can be a helpful starting point when comparing products, but the right amount for you may depend on your diet, activity level, and health needs. People aged 65 and older should aim for about 1 to 1.2 grams of protein per kilogram per day. This is a general guideline, not a target that works for everyone. Remember to count protein from food and supplements, and ask a health care provider or registered dietitian what’s right for you.
Third-party testing and certification
Look for protein powders tested by an independent organization. This can help you learn more about a product’s quality. Third-party testing can confirm whether a protein powder has been tested for contaminants and other substances. Certifications can also show how a product is made and which standards it meets. Matey recommended checking for independent testing and certifications. These may provide information about ingredient quality, manufacturing standards, or contaminant testing, depending on the certification. Keep in mind that these labels don’t all mean the same thing. Check what each certification covers so you know what it tells you about the product.
Ingredients and additives
Read the full ingredient list before buying a protein powder. Labels name the ingredient with the highest amount first, so look for protein sources that are listed at the top of the product list. Some products contain added sugars, artificial sweeteners, flavors, or other ingredients you may prefer to avoid. Ingredients such as lecithin and xanthan gum are emulsifiers or stabilizers, which helps with product shelf life. Simpler formulas can make it easier to know what you are getting in each serving.
Matey recommended avoiding artificial ingredients, artificial sweeteners, and certain fibers, such as inulin and chicory root, which can upset digestion. She also said to avoid ingredients you cannot recognize on the label. It’s also worth considering possible contaminants. “There can be heavy metals in protein powders,” said Matey. This includes lead, cadmium, and arsenic. Some research has found higher concentrations of certain heavy metals in plant-based protein powders than in animal-based powders. Levels can vary by product. Heavy metals can be harmful when exposure builds up over time. So far, typical protein powder use isn’t linked to adverse health effects.4 Still, if you prefer to avoid these, third-party testing can help you choose products checked for these contaminants.
Taste and mixability
Taste matters because you are more likely to use a protein powder you enjoy. Protein powders vary in flavor profile depending on the protein source and any added flavors or sweeteners. Some taste mild, while others can be chalky, gritty, or very sweet. Mixability is also important. Some powders blend smoothly with water or milk, while others may clump or leave a thick texture. If you plan to use protein powder every day, look for a flavor and texture you like. Read customer reviews or try a small container first to find a good fit.
Brand reputation and transparency
Choose a brand that clearly shares product information. Brands should disclose their ingredients, nutrition facts, testing, and manufacturing practices. A trustworthy company should make these details easy to find. Also be cautious of brands that make big health claims without solid evidence. A higher price does not always mean a better product. Look for clear labels, reliable testing, and a protein powder that meets your needs without unnecessary extras.
Potential side effects of protein powder for women
Protein powder can be a helpful way to get more protein, but it may cause side effects in some people. Around 16% of older adults who responded to our survey said they experienced unwanted side effects when taking a protein powder.5 Taking too much of a powder at once may lead to digestive problems, such as nausea, constipation, diarrhea, gas, and bloating. Follow the package directions or ask your health care provider how to add protein powder to your diet gradually.
“Too much protein can cause bloating and constipation, and strains the kidneys,” said Dr. Qiao. “If you have kidney issues, consult a doctor first.” People with kidney disease may need to limit or adjust their protein intake. If you have kidney concerns, speak with your health care provider before using a protein powder. Whey protein may affect those who are lactose intolerant or have dairy allergies. If a powder causes ongoing discomfort, stop using it and ask a health care provider about other options.

In our August 2026 survey of 250 older adults, 41% said they were “very concerned” about losing muscle mass or strength as they age.5
Protein powder drug interactions
Protein powder itself has few known interactions with medications. But a product’s ingredients matter. Some powders contain added herbs, vitamins, minerals, or other ingredients. These ingredients could affect your health or interact with certain medicines. Always read the full label, especially if you take prescription drugs or other supplements.
“There are not many interactions between protein powder and medicine,” said Dr. Qiao. If you take medications, consult your health care provider before using a protein powder or other supplement.
