Shaking up just a few scoops of protein powder with water could also be a part of your post-workout restoration ritual. Or, maybe you favor mixing it in your day by day smoothie so the drink turns into much less a snack and extra a meal. However how a lot have you learnt about your most well-liked protein powder and what it’s or isn’t doing in your well being?
Each cell in your physique accommodates protein, a macronutrient made up of chains of amino acids, the so-called constructing blocks of life. It helps hold your physique working easily, from aiding in digestion and regulating hormones, to rushing up train restoration and supplying blood with oxygen.
But in contrast to fat and carbohydrates, the opposite two vitamins you want most, protein doesn’t get saved in your physique, explains Simin Levinson, M.S., a registered dietitian nutritionist and scientific professor within the Faculty of Well being Options at Arizona State College.
“People sometimes are protein-sparing, which means that though we are able to use protein for vitality—we have now the metabolic pathways to take action—it’s preferable that carbohydrates and fat are the predominant sources of gas,” Levinson tells Fortune. “That’s as a result of protein performs such a important, useful position…and if that protein isn’t offered, we begin breaking down physique tissues so as to produce these amino acids.”
Loads of meals naturally comprise protein, however demand for protein dietary supplements continues to surge. The worldwide protein complement market was valued at $5.8 billion in 2022, with a projected 8% compound annual progress charge by way of 2030, based on Grand View Analysis. Under, Levinson and different vitamin consultants share three issues to think about earlier than shopping for your subsequent tub of protein powder.
Select complete meals over protein powder when attainable
There’s no denying the comfort of protein powder; you may put together it in seconds, with no refrigeration or cooking concerned. Nonetheless, the complement could not gas your physique with the number of proteins that come from a balanced food plan of complete meals, Levinson says: “We have now many nice sources of protein obtainable within the Western food plan.”
9 of the 20 completely different amino acids are thought-about important, which means your physique can’t make them by itself they usually should be obtained by way of meals. Meals that comprise all important amino acids are referred to as full proteins and are usually animal-based. Soy, quinoa, and hemp seeds are among the many few plant-based full proteins, which will help vegans and vegetarians spherical out their protein consumption.
The 2020–2025 Dietary Pointers for Individuals embrace these protein sources:
Most protein powders in the marketplace comprise high-quality proteins, says Roger Fielding, Ph.D., a professor on the Tufts College Friedman Faculty of Vitamin Science and Coverage. Nonetheless, they will additionally depart key vitamins out.
Whey, for instance, is a byproduct of producing cheese. Consuming a whey protein complement in isolation could gas you with milk protein, however consuming a glass of milk as a substitute may also present calcium and vitamin D, Fielding explains.
“We at all times wish to encourage individuals to get their dietary necessities from meals sources,” Fielding tells Fortune, “largely as a result of there’s most likely different elements in these meals which might be wholesome, that additionally could also be vital for us to devour.”
FDA doesn’t approve premarket protein powder
Take note protein powder is a dietary complement, not a substitute, stresses Tyler Becker, Ph.D., an assistant professor within the Division of Meals Science and Human Vitamin at Michigan State College. And since it’s a complement, the Meals and Drug Administration (FDA) isn’t approved to approve it for security and effectiveness earlier than it hits your pantry.
“You don’t actually need protein powder, the typical individual doesn’t,” Becker tells Fortune. “Quite a lot of athletes don’t as properly, besides below sure conditions, and the explanation [why] is said to the regulation of it.”
The FDA does regulate such dietary supplements however often after they’re in the marketplace, leaving the onus of correct labeling on producers. Class-action lawsuits have accused some corporations of “protein spiking,” utilizing cheaper, free-form amino acids moderately than the proteins marketed. The FDA has additionally despatched a number of corporations warning letters, deeming their protein merchandise “adulterated dietary dietary supplements.”
Some protein powders could comprise toxins. The nonprofit Clear Label Challenge in 2018 examined greater than 130 top-selling powders for heavy metals and different contaminants. Greater than half contained bisphenol A (BPA), an industrial chemical which will trigger most cancers or different well being issues. One powder had 25 occasions the allowed restrict of BPA in a single serving.
On the entire, although, protein dietary supplements are secure, says Fielding, who generally consumes whey powder himself. Becker recommends consulting a registered dietitian if you happen to plan to include protein powder into your food plan—significantly if you happen to’re vegan or vegetarian and don’t wish to miss out on needed vitamins. As a result of dietary dietary supplements could work together with some medicines, the FDA additionally advises asking your physician in the event that they’re acceptable.

The choices could really feel overwhelming, however the very best protein powder is the one that enhances your style, food plan, way of life, and general well being, based on Levinson. Whey protein has lengthy been the gold normal amongst athletes due to its fast digestion and assimilation, says Levinson, the consulting sports activities dietician for the WNBA’s Phoenix Mercury and previously for the NBA’s Phoenix Suns.
“However these days, there are some plant-based proteins which might be formulated so properly that they supply an awesome supply and the identical quantity of protein,” she tells Fortune. “Inside the WNBA and throughout the NBA, there’s a pattern of athletes selecting extra plant-based choices for his or her meals and for his or her dietary supplements.”
The FDA usually recommends consuming 50 grams of protein day by day, however chances are you’ll want extra relying in your age, weight, and stage of bodily exercise.
“In case you’re bodily lively, whether or not you’re doing endurance train or weightlifting, you wish to take into consideration upping that to possibly 75–100+ grams per day,” Fielding tells Fortune. “Begin enthusiastic about the place the sources of protein can come from in your food plan.
