The TL;DR: The Government Finally Caught Up to Sam
The government just released the new 2025-2030 Dietary Guidelines for Americans and finally admitted what Dietitians like Sam have been saying forever: you need way more protein than you think. Like, 50-100% more. The new recommendation is 1.2-1.6 grams per kilogram of body weight per day, up from 0.8g. For the average person, that’s roughly 80-110 grams daily.
They also want you eating whole food and cutting out sugar and ultra-processed junk. Wild, we know.
ProSo was literally built on these exact principles. 10g of clean whey protein isolate, zero sugar, no artificial anything, 45 calories. Turns out when you let a Registered Dietitian formulate your soda instead of a marketing team, you end up ahead of the curve.
Remember When Sam Said You Needed More Protein?
The federal government just basically copy-pasted his notes.
The 2025-2030 Dietary Guidelines dropped, and honestly? It reads like Sam’s been ghost-writing for the USDA. More protein; ditch the processed stuff.
The things he’s been saying since before we even had a brand name.
Here’s what changed, why it matters, and how ProSo has been doing this the whole time.
The Big Protein Plot Twist
For decades, the official word was 0.8 grams of protein per kilogram of body weight per day. About 54 grams if you weigh 150 pounds. And that number? It was literally designed to keep you from dying of protein deficiency. That’s it. That was the bar.
The new guidelines? 1.2 to 1.6 grams per kilogram per day. For that same 150-pound person, that’s now 82 to 109 grams daily. Almost double.
Why the jump? Because science finally convinced the government that “not dying” and “actually thriving” are two different things. More protein helps you hold onto muscle as you age, keeps you fuller longer, supports weight management, and helps your body function better overall.
Sam’s take: “I’ve been recommending 1.2-1.6g/kg for years to basically everyone. The science has been there forever. The old 0.8g/kg recommendation was literally just ‘here’s enough to not die of protein deficiency,’ not ‘here’s what you need to actually thrive.’ Better late than never, I guess.”
Dalton’s take: “The government moves slower than my grandma on her morning walk.”
How ProSo Fits Into All This
We didn’t design ProSo to match future government guidelines. We just let Sam do his thing while Dalton made sure it didn’t taste like punishment. Turns out following actual nutrition science gets you pretty far.
Here’s why ProSo already checks every box:
10g of whey protein isolate per can. The good stuff. 90% pure protein, all essential amino acids, easy to digest, no chalk, no clumps. The guidelines even note that 10g is the minimum effective dose for lean body mass benefits in a single sitting. We didn’t pick that number because it sounded nice.
Zero sugar, zero artificial sweeteners. We use OnoSweet™, a patented fermented rice sweetener using Reb M. Clean sweetness, no bitter aftertaste, no blood sugar spike. The new guidelines say to avoid both added sugars AND artificial sweeteners. We’ve been doing that since day one.
Only 7 ingredients. You can read the label without a chemistry degree. The guidelines push for minimally processed foods. That’s us.
45 calories. Perfect whether you’re watching your intake, on a GLP-1, or just trying to make a smarter swap.
Formulated by an actual Registered Dietitian. Not a marketing team. Sam has a master’s degree, 1,200+ supervised hours, a board certification, and a license he has to actively maintain. When we say dietitian-formulated, we mean it.
What Hitting Your Protein Goals Actually Looks Like
Say you weigh 150 pounds. You need about 82-109g of protein per day. Here’s how that plays out without overhauling your entire life:
Breakfast: Two eggs (12g) + a ProSo Sunny Meyer Lemon (10g) = 22g
Mid-morning: Greek yogurt (15g) = 37g total
Lunch: Grilled chicken salad (30g) + a ProSo Cheeky Cherry Vanilla (10g) = 77g total
Afternoon snack: Handful of almonds (6g) = 83g total
Dinner: Salmon or whatever protein you actually like (25g) = 108g total
See how ProSo just slides in there? No blending, no prep, no thinking about it. That’s kind of the whole point.

Frequently Asked Questions
How much protein do I actually need per day?
The new guidelines say 1.2-1.6 grams per kilogram of body weight. If you weigh 150 pounds, that’s roughly 82-109g daily. Significantly more than the old recommendations.
Why did the guidelines increase the protein recommendation?
The old 0.8g/kg was the minimum to avoid deficiency, not the amount needed to actually thrive. The new guidelines account for muscle maintenance, healthy aging, metabolism, and feeling full throughout the day.
Is ProSo considered ultra-processed?
Nope. Seven ingredients: carbonated water, whey protein isolate, natural flavors, ascorbic acid, sodium citrate, OnoSweet™ (fermented rice sweetener), and fruit and vegetable juice for color. No refined sugars, no artificial sweeteners, no chemical additives. When the guidelines say avoid ultra-processed foods, they mean the stuff with 47 ingredients you can’t pronounce. That’s not us.
Can kids drink ProSo?
Yes. No caffeine, no sugar, no artificial anything. Clean protein that supports growth and development, in something that actually tastes good. No negotiating required.
Why whey protein isolate and not plant protein?
Whey isolate is a complete protein with all the amino acids your body needs, and your body absorbs it easily. The guidelines specifically note that animal proteins have better amino acid profiles and bioavailability. We’re not anti-plant protein, but whey isolate is the gold standard for what we’re trying to do.
Where is ProSo made?
Greenville, South Carolina. FDA-registered, cGMP-compliant facility. Local and legit.
How many can I drink per day?
As many as you want. No sugar, no caffeine, no artificial junk. Drink one, drink three. Whatever helps you hit your goals.
