A Whey Protein Crunch Is Fueling New Startups, While Medicare Part B May Pay for Free Nutrition Counseling for Eligible Retirees With Diabetes or Kidney Disease

A whey protein shortage is changing what many older adults with diabetes and kidney disease add to their shakes, and many do not realize Medicare already covers the professional who should be guiding that choice.

The whey shortage is forcing manufacturers to look for substitutes. Some suppliers have said certain products are sold out well into the future, while rising demand from people using GLP-1 drugs is intensifying the pressure. Food makers are turning to soy and pea protein, and startups are trying to solve the problem with fermentation-based alternatives. For older adults who depend on protein shakes, the shortage raises both cost and nutrition concerns.

Consider a 68-year-old woman with type 2 diabetes and early kidney disease who has recently begun a GLP-1 medication. She may not have asked whether her shakes fit her kidney care plan. Medicare Part B can cover a visit with a registered dietitian at no cost to help answer that question.

Who Can Get $0 Nutrition Counseling

To qualify, you must have diabetes, certain kidney diseases, or a kidney transplant within the past 36 months. For kidney disease, Medicare generally covers people with moderate to severe loss of kidney function or kidney failure who are not on dialysis. If you receive dialysis at a facility, nutrition counseling is already part of that care.

You also need a referral from your doctor confirming the condition. High blood pressure, high cholesterol, or a weight-loss goal by itself does not make you eligible for this benefit.

Three Hours in the First Year, Two More Each Year After That

Coverage begins with three hours of medical nutrition therapy in the first calendar year. After that, you can receive up to two hours of follow-up services each calendar year. Covered sessions cost nothing when provided by a participating Medicare provider.

That is different from most Part B services. In 2026, beneficiaries first have to meet a $283 annual deductible, up from $257 in 2025, and then pay coinsurance. Eligible nutrition visits bypass both charges.

Be mindful of the calendar. Medicare does not carry unused counseling hours into the following year. If 2026 is your first year using the benefit, any unused part of the initial three hours expires on December 31.

You may qualify for additional hours if your health changes. A physician can approve them after a change in diagnosis, condition, or treatment related to diabetes or kidney disease that requires a new nutrition plan. That could include starting insulin or a decline in kidney function. Medicare can also cover diabetes self-management training at the same time as nutrition therapy. The two benefits have separate hour limits, and they generally cannot be delivered on the same day.

The Counseling Is Covered, Not the Protein Powder

The benefit pays for the professional advice, not the groceries. Federal rules describe it as nutritional diagnostic, therapeutic, and counseling services from a registered dietitian or nutrition professional. Sessions can include an initial nutrition and lifestyle assessment, individual or group therapy, and follow-up visits. It covers medical nutrition therapy, not free whey protein. Protein tubs, bars, and fortified foods still come out of your own pocket.

That makes the counseling especially valuable during a shortage. For someone with reduced kidney function, a dietitian may recommend a protein target much lower than what shake marketing suggests, or replace powder with ordinary foods. Either way, the advice can save money on a product whose price keeps climbing. It makes sense to see the dietitian before buying another tub.

Some Medicare Advantage plans offer over-the-counter allowances that can help pay for certain health products. Coverage varies by plan. If that matters to you, check the plan’s Evidence of Coverage during the open enrollment period.

Steps to Take Before the Year Ends

1. Ask your doctor for a medical nutrition therapy referral. Make sure the record includes the qualifying diagnosis: diabetes, chronic kidney disease with your GFR, or the date of your transplant.
2. Schedule an appointment with a registered dietitian who accepts Medicare. Use the provider search on Medicare.gov. Confirm that the dietitian participates in Medicare and that the visits will be covered at no cost. If you are in Medicare Advantage, verify that the provider is in network.
3. Use your annual hours before they expire. If you began a new medication or your lab results changed during the year, ask your doctor whether you qualify for extra hours under the changed-condition rule.
