One scoop has 200 calories with 22g protein, plus a mix of carbs and fat that can shift a bit by flavor.
When you buy a tub of BSN SYNTHA-6, the front label sells the vibe: “milkshake taste,” “protein matrix,” “use anytime.” Cool. The part that decides if it fits your day is the Nutrition Facts panel and ingredient list.
This article breaks down what the label says, what the numbers mean in plain terms, and how to use the facts to match your goal, your taste pick, and your stomach.
What Counts As A Serving On The Label
Start with serving size. Most SYNTHA-6 tubs list About 1 scoop (47g) as a serving. That detail matters because “one scoop” can mean a level scoop, a rounded scoop, or a scoop you packed down.
If you want repeatable numbers, use a kitchen scale the first few times. Scoop volume can drift when the powder settles in shipping, or when humidity clumps it.
Also check servings per container. A 5 lb tub often lists 48 servings on the panel. That lets you do quick math on cost per serving and calories per day.
BSN Syntha-6 Nutrition Facts For One Scoop And Two Scoops
Most people buy SYNTHA-6 for the blend: it’s not a pure whey isolate that vanishes into water. It’s meant to taste like a treat, so you’ll see more carbs and fat than a “lean” whey isolate.
For many flavors, one serving sits at 200 calories with 22g protein. If you take two scoops, you’re doubling almost everything on the panel. That sounds obvious, yet it’s where plans get messy fast.
A two-scoop shake can slide into “meal-sized” calories once you add milk, peanut butter, oats, or syrup. If that’s the plan, great. If it’s not, you’ll want to spot the add-ons before they spot you.
Label Quick Read
- Calories tell you the total energy per serving.
- Protein tells you how much you’re adding to your daily target.
- Total carbs, total sugars, added sugars tell you how sweet the base is.
- Total fat and saturated fat tell you how rich the serving is.
- Sodium and cholesterol can matter if you track them day to day.
Why Flavor Can Change The Numbers
Two tubs can both be SYNTHA-6 and still show small shifts in saturated fat, sodium, fiber, minerals, and total sugars. Cocoa, flavor systems, and tiny ingredient swaps can change the totals.
So treat the panel on your tub as the final word. Use online numbers as a starting point, not a promise.
Protein Blend And Ingredients
SYNTHA-6 is built as a multi-source protein mix. On many tubs, the protein matrix lists whey protein concentrate, whey protein isolate, calcium caseinate, micellar casein, milk protein isolate, and egg albumen, with glutamine peptides listed in the blend as well.
You can see that same “matrix” language on the official product page at goBSN’s SYNTHA-6 product listing.
What That Means In Real Food Terms
Whey tends to mix fast and digest fast for a lot of people. Casein tends to sit thicker and can feel slower in the stomach. Egg protein can add to texture. The blend is part of why SYNTHA-6 often tastes more like a dessert shake than a thin whey drink.
If you do well with dairy and like thicker shakes, that blend can be a win. If dairy sits heavy for you, start with a half serving and see how your gut reacts.
Sweeteners And Mix Helpers
Many flavors list sucralose and acesulfame potassium. You’ll also see things like lecithin and gums that help mixing and texture. That’s normal for a powder aiming for a creamy mouthfeel.
Carbs, Sugars, And The Part People Miss
Lots of shoppers scan calories and protein, then stop. The carb line is where you find the “hidden” reason a shake feels like a shake.
On many tubs, total carbs land around 15g per scoop. Total sugars can be a few grams, and you may see a small amount of added sugar listed too. Those numbers can shift by flavor, so check your panel.
If you’re tightening carbs, the most useful move is swapping what you mix it with. Water keeps the label true. Milk adds more protein, but it also adds more carbs and calories.
Fats And Texture
SYNTHA-6 often lists 6g total fat per scoop, with saturated fat around 1.5g to 2g depending on flavor. Fat is part of why the shake feels rich and why it can stick with you longer than a low-fat whey isolate.
If you’re watching calories, fat is the fastest place for a shake to creep upward once you add nut butters, creamers, or full-fat milk.
Minerals And Sodium
Protein powders aren’t just macros. Many SYNTHA-6 labels list calcium, potassium, phosphorus, and magnesium, with amounts that vary by flavor. Sodium can also vary, so check if you track it.
If you’re using SYNTHA-6 once per day, these mineral lines won’t replace a balanced diet. They do help you compare tubs when you’re choosing between flavors.
Nutrition Facts By Flavor
The table below uses two official label panels from GNC’s hosted PDFs for a 5 lb tub: Chocolate Milkshake and Vanilla Ice Cream. Use it as a side-by-side view, then match your own tub’s panel to the closest option.
| Nutrient (Per 47g Scoop) | Chocolate Milkshake | Vanilla Ice Cream |
|---|---|---|
| Calories | 200 | 200 |
| Protein | 22g | 22g |
| Total Fat | 6g | 6g |
| Saturated Fat | 2g | 1.5g |
| Cholesterol | 70mg | 65mg |
| Sodium | 230mg | 190mg |
| Total Carbohydrate | 15g | 15g |
| Dietary Fiber | 1g | 0g (listed as not a source) |
| Total Sugars | 3g | 4g |
| Added Sugars | 2g | 2g |
| Calcium | 190mg | 200mg |
| Iron | 1.4mg | 0mg (listed as not a source) |
| Potassium | 350mg | 240mg |
| Phosphorus | 130mg | 160mg |
| Magnesium | 40mg | 20mg |
How To Read The % Daily Value Lines
% Daily Value is a label tool based on a 2,000-calorie diet. It’s not a personal target, but it helps you rank foods fast.
If a nutrient shows 5% DV or less, it’s low per serving. If it shows 20% DV or more, it’s high per serving. That simple rule works well for sodium, saturated fat, and added sugar.
If you want a refresher on how DV works and why some nutrients are listed, the FDA’s guide to using the Nutrition Facts label is the cleanest source.
Allergens And Dietary Fit
Many SYNTHA-6 flavors list allergens that include milk, egg, soy, and wheat. If you avoid any of those, the label is non-negotiable reading. If you’re unsure about a reaction, start with a small portion on a low-stakes day, not right before a workout or a long drive.
Also check for lactose tolerance. Even when whey isolate is in the blend, concentrate and milk proteins can still bring lactose along for the ride.
Mixing Choices That Change The Numbers
The label is written for the powder alone. Your blender choices write the rest of the story. Here are the common swaps that change the nutrition fast:
- Water: keeps calories closest to the label.
- Skim or low-fat milk: raises protein and carbs.
- Whole milk: raises calories and saturated fat.
- Oats, nut butter, oil: raises calories fast and can turn a shake into a full meal.
If you track intake, log the add-ins once, then reuse the recipe in your app. That keeps the numbers steady week to week.
Common Use Cases And What The Label Tells You
SYNTHA-6 can work in more than one setup. The label helps you choose the right timing and portion. The table below is a practical cheat sheet built from the panel numbers, not vibes.
| Goal | Label Line To Watch | Simple Move |
|---|---|---|
| Higher daily protein | Protein grams per scoop | Use one scoop with water, add food protein at meals |
| Calorie control | Calories, fat, added sugars | Skip high-calorie add-ins; keep it a one-scoop shake |
| Weight gain phase | Calories plus carbs | Mix with milk and add oats, then track the total |
| Post-workout shake | Protein plus total carbs | Pair one scoop with a carb food you already tolerate |
| Late-day snack | Fat, carbs, texture | Blend with ice and water for volume without extra calories |
| Low sugar focus | Total sugars and added sugars | Pick the flavor with lower sugars on the tub you buy |
| Sodium tracking | Sodium mg | Check flavor panels; some list higher sodium |
Picking A Flavor Without Guesswork
If taste is your main driver, read the panel anyway. Small shifts in sodium, saturated fat, fiber, and minerals can add up across daily use.
If you’re deciding between two tubs at a store, snap a photo of each Nutrition Facts box, then compare at home. That beats relying on a retailer listing that might be out of date.
Storage And Label Changes Over Time
Keep the lid tight, store it in a cool, dry place, and use a dry scoop. Moisture clumps powders and can make scoops less consistent. Your macros don’t “go bad” in a week, but your scoop size can drift if the powder cakes.
Also keep an eye on label updates. Brands can adjust flavor systems, serving counts, and mineral lines. That’s one more reason to treat the panel on your tub as the final source.
Fast Checklist Before You Buy Again
- Check serving size in grams, not just “one scoop.”
- Check calories per scoop and decide if you’ll use one scoop or two.
- Check added sugars and saturated fat if you track them.
- Check sodium if you have a daily cap.
- Check allergen line for milk, egg, soy, and wheat.
- Pick the mixing plan first, then buy the powder that fits it.
