“Humans typically are protein-sparing, meaning that although we can use protein for energy—we have the metabolic pathways to do so—it is preferable that carbohydrates and fats are the predominant sources of fuel,” Levinson tells Fortune. “That’s because protein plays such a critical, functional role…and if that protein isn’t provided, we start breaking down body tissues in order to produce those 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 development charge by means of 2030, in response to Grand View Research.

Select entire meals over protein powder when doable

There’s no denying the comfort of protein powder; you’ll be able to 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 regimen of entire meals, Levinson says: “We have many great sources of protein available in the Western diet.”

9 of the 20 totally different amino acids are thought of important, which means your physique can’t make them by itself they usually should be obtained by means of meals.

“You don’t really need protein powder, the average person does not,” Becker tells Fortune. “A lot of athletes do not as well, except under certain situations, and the reason [why] is related to the regulation of it.”

The FDA does regulate such supplements however normally after they’re on the market, leaving the onus of correct labeling on producers. Class-action lawsuits have accused some firms of “protein spiking,” utilizing cheaper, free-form amino acids reasonably than the proteins marketed.

Some protein powders could comprise toxins. The nonprofit Clean Label Project 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 instances the allowed restrict of BPA in a single serving.

On the entire, although, protein dietary supplements are secure, says Fielding, who typically consumes whey powder himself. Becker recommends consulting a registered dietitian if you happen to plan to include protein powder into your food regimen—notably if you happen to’re vegan or vegetarian and don’t wish to miss out on mandatory vitamins. As a result of dietary dietary supplements could work together with some drugs, the FDA additionally advises asking your physician in the event that they’re acceptable.

“But nowadays, there are some plant-based proteins that are formulated so well that they provide a great source and the same amount of protein,” she tells Fortune. “Within the WNBA and within the NBA, there is a trend of athletes choosing more plant-based options for their food and for their supplements.”
