Whilst Rhonda tries to get her protein her diet, where needed she supplements her protein intake with protein powder.
According to Q&A #57, she has a few criteria when choosing which to take:
- She prefers whey isolate to whey concentrate because, broadly speaking, isolate has a higher protein content, less lactose, less fat and less calories.
- She prefers whey powder from grass-fed cows, as the omega-3 to omega-6 ratio is better. Specifically, higher in omega-3s and lower in omega-6s, compared to the non-grass-fed versions. Organic if possible.
- She prefers cold processed or micro-filtered protein, as it contains more of the the micronutrients found in whey.
According to her December 2025 Q&A (#76) she’s currently using this particular product:
- Momentous – Whey Protein Isolate (see 15-35% off discount code)
She didn’t mention which flavours specifically.
Her reason for switching away from the Thorne product below was due to Momentous not using any emulsifiers. Her belief is that it’s easier on the gut without an emulsifier.
Her previous brand choice was:
- Thorne – Whey Protein Isolate – Vanilla flavour
Prior to using the unflavoured veresion she was using their chocolate flavour. She switched away from it to minimize potential heavy metals from the cocoa.
Rhonda’s criteria for protein powder is very similar to Peter Attia, who uses a brand called Promix (see 1:48:23 on YouTube where they discuss this).
They make a Grass Fed Whey Isolate version which comes in chocolate, vanilla and unflavoured versions. For 10% off Promix orders, see this discount code.
