Save Money With These Whey Protein Powder Alternatives

Whey protein is getting more expensive. The relentless rise in the popularity of protein-rich foods has meant that whey producers have been stretched to their limits, and as supply runs thin, prices go up – and with a 50% rise in the first three months of 2026, it’s never cost so much to keep your protein intake high. Now, there’s obviously another conversation to be had here, which is whether we need all this protein in the first place – but if you’re training to build muscle, these increased prices might put a strain on your wallet.

So, is it time to pivot to different protein powders? Perhaps. There are a couple of alternatives out there that are either cheaper than whey protein or may well be soon, due to its increased expense – and we thought we’d lay out a couple of options.

Soy Protein

Soy protein powders are usually cheaper than whey protein powders, and they’ve long been an option for people following plant-based diets. Soy protein has been found to increase muscle tissue at a similar level to whey protein, and while some people state that it has less bioavailability, it’s still a good choice for all but the most ardent bodybuilders.

That said, there are a few things to consider. Soy protein powders can have a higher carbohydrate content and contain less leucine (an amino acid) than whey protein powders. It can also have a different taste and be slightly chalkier and less smooth. For the best nutritional profile, it’s best to go for a soy protein isolate, which usually has a comparable protein content to whey protein.

Pea Protein

Pea protein prices can vary: While some options will be cheaper than whey, others can be more expensive. Given the rising price of the latter, though, it may well become consistently cheaper, and like soy protein, it’s a good option for plant-based eaters. It’s also largely allergen-friendly (although always check the label), and for some people, can be easier to digest than whey.

Like soy protein, though, its taste can vary, and that chalkiness can come through here, too – which can make it harder to incorporate into drinks. Pea protein is also low in methionine and is best paired with another plant-based protein (like rice protein) to complete the amino acid profile. It can also have a higher sodium content than whey protein.

Brown Rice Protein

Brown rice protein powder may be an underrated choice in terms of cost. You can pick up bags of this protein relatively cheaply, and like pea protein, it’s an easily digestible option for most people. If you consume enough of it, it can be just as effective as whey protein in supporting muscle growth and repair, although protein content may vary between the two.

That said, brown rice protein has an incomplete amino acid profile and is best paired with another option – and there have also been concerns about its heavy metal content. As brown rice can absorb arsenic as it grows, some people worry that certain protein powders contain elevated levels. It’s best to opt for a brand that thoroughly tests its powders for heavy metals.
