A Whey Protein Shortage Is Sparking a Startup Gold Rush. Medicare Part B Can Cover Three Hours of Nutrition Counseling at $0 for Eligible Retirees With Diabetes or Kidney Disease
A whey protein shortage is reshaping what older adults with diabetes and kidney disease put in their shakes, and most of them have no idea Medicare already covers the expert who should be making that call.

A whey protein shortage is sending manufacturers scrambling for alternatives. Suppliers have reported selling out of certain products through the end of 2026, while rising demand from GLP-1 users is adding pressure. Some food companies are switching to soy and pea protein, and startups are developing alternatives through fermentation technology. For older consumers relying on protein shakes, the shortage raises questions about both cost and nutrition.
Picture a 68-year-old with type 2 diabetes and early kidney disease who just started a GLP-1 drug. But she hasn’t asked whether those shakes fit her kidney treatment plan. Medicare Part B could cover a consultation with a registered dietitian at no cost to help her find out.
Who Qualifies for $0 Nutrition Counseling
To qualify, you must have diabetes, certain types of kidney disease, or have received 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 aren’t receiving dialysis. If you’re getting dialysis at a facility, nutrition counseling is already included in your care.
You’ll also need a referral from your doctor confirming your condition. High blood pressure, high cholesterol or a weight-loss goal alone won’t qualify you for this benefit.
Three Hours This Year, Two Hours Every Year After
Coverage starts with three hours of medical nutrition therapy (MNT) in the first calendar year. After that, you get up to two hours of follow-up services each calendar year. You pay nothing for covered sessions when you see a participating Medicare provider.
Compare that with most Part B care. In 2026 you first meet a $283 annual deductible, up from $257 in 2025, and then pay coinsurance. Eligible nutrition visits skip both.
Watch the calendar. Medicare doesn’t let you carry unused counseling hours into the next year. If 2026 is your first year receiving the benefit, any unused portion of your initial three hours expires December 31.
You can get more hours when your health shifts. Your physician can clear them. They authorize the extra hours after a change of diagnosis, medical condition, or treatment regimen related to diabetes or renal disease that requires a change in MNT. That could mean starting insulin or a drop in kidney function. Medicare can also cover diabetes self-management training alongside nutrition therapy. Both benefits have separate hour limits, and the services generally cannot be provided on the same day.
Counseling Is Covered, the Powder Is on You
The benefit pays for expertise. Federal rules define it as nutritional diagnostic, therapeutic, and counseling services provided by a registered dietitian or nutrition professional. Sessions can include an initial nutrition and lifestyle assessment, individual or group therapy, and follow-up visits. The benefit covers medical nutrition therapy, not a free protein-powder allowance. Tubs of whey, protein bars and fortified groceries stay in your grocery budget.
That’s why the counseling is worth more than it looks during a shortage. For someone with reduced kidney function, a dietitian may set a protein target well below what shake marketing implies, or swap powder for regular foods. Either way, you spend less on a product whose price continues going up. Book the dietitian before you buy another tub.
Some Medicare Advantage plans add over-the-counter allowances that can cover certain health products. The details differ by plan. If that matters to you, check the plan’s Evidence of Coverage during the open enrollment period now underway.
What to Do Before December 31
- Ask your treating MD or DO for a medical nutrition therapy referral. Make sure the chart lists the qualifying diagnosis: diabetes, chronic kidney disease with your GFR, or the date of your transplant.
- Book with a registered dietitian who takes Medicare. Use the provider finder on Medicare.gov. Confirm that the dietitian participates in Medicare and that your visits will be covered at no cost. Advantage members should check that the dietitian is in network.
- Your 2026 hours won’t last forever. Make sure to use them before they run out. If you started a new drug or your lab results changed this year, ask your doctor to refer you for additional hours under the changed-condition rule.
