RSP TrueFit Review

RSP TrueFit is a high-protein meal-replacement powder with grass-fed whey protein and probiotics. This product offers a balance of digestion-supporting ingredients, healthy fiber, fruits, vegetables, and high-quality protein. With 25 grams of protein per serving, it doubles as a pre-workout supplement and a meal-replacement option on-the-go. There are many high-protein powders on the market today, and not all of them are created equal. Let’s take a closer look and see how this one fares with our review of RSP TrueFit.

Benefits Of RSP TrueFit

Contains Quality Protein

TrueFit contains 25 grams of high-quality protein from grass-fed, pasture-raised protein that is sourced from family farms in the USA. This grass-fed whey protein delivers protein that is catered towards athletes and for individuals looking for meal replacement options on the go. It is also ideal for pre-workout fuel, especially as whey protein boasts potent protein and amino acids. Branched-chain amino acids and essential amino acids are extremely important for the body, especially when it comes to post-workout recovery and building muscle.

Promotes Healthy Digestion

Included in TrueFit’s ingredients is a digestive blend that consists of probiotics and prebiotic fiber. There are 1 billion CFUs of probiotics included in TrueFit’s formula, along with 8 grams of fiber from sweet potato and other low-glycemic prebiotic fiber. This prebiotic fiber assists in bowel regularity and also helps feed and nourish the probiotics or good bacteria in your gut.

Boosts Immune System

TrueFit contains a superfood blend as well that includes essential ingredients like strawberries, tart cherries, elderberry, broccoli sprouts, tomato, spinach, and kale. These superfoods help boost the immune system by providing a wide array of essential vitamins and nutrients. The digestive blend also helps promote a healthy immune system as well by assisting in the effective absorption of some of these essential vitamins and micronutrients.

RSP TrueFit Ingredients

The main ingredient in RSP TrueFit is the all-in-one grass-fed protein from pasture-raised, organic cattle. This whey protein boats a complete amino acid profile as well as 25 grams of protein per serving. This protein and amino acids help support pre-workout fuel and energy and help boost athletic performance and lean muscle growth. Whey protein also helps support post-workout recovery and prevents muscle fatigue and soreness after workouts, primarily due to the amino acid content and the branched-chain amino acids.

RSP TrueFit also contains a superfood blend consisting of superfood ingredients like strawberries, cherries, broccoli, spinach, kale, carrot, broccoli sprouts, elderberry, and cranberry. This entirely organic superfood blend helps support proper digestion and helps boost the immune system as well. These fruits and vegetables deliver essential vitamins and micronutrients like calcium, Vitamins A, E, D, K, and C, and prebiotic fiber to help support healthy digestion and nourish the probiotics.

Along with the superfood blend, RSP TrueFit includes 1 billion CFUs of probiotics to support healthy digestion and a healthy gut microbiome. MCT oil powder is also included as a source of healthy fats. This healthy fat source originates from coconuts and can help provide energy and even facilitate a more effective fat burn during workouts. This fat source also helps provide a more balanced meal replacement option and may even help these fat-soluble nutrients and vitamins circulate throughout your body more efficiently.

Cocoa powder is also included in TrueFit’s formula for natural flavoring and stevia for a sweetener source.

RSP TrueFit Supplement Facts

Is RSP TrueFit Really Healthy?

In terms of protein powders and meal-replacement options, RSP TrueFit is pretty healthy. The whey protein is grass-fed, pasture-raised, and family-farmed, which is very important for this kind of protein. Whey protein should also be sourced ethically and should be hormone-free, which this whey protein is. The superfood blend is also really beneficial, and most protein powders do not contain this kind of blend. The digestive blend is also very beneficial and helps support a more efficient uptake of these nutrients and vitamins.

Stevia is a good sweetener option, although be cautious of consuming too much stevia as it can cause digestive issues and discomfort, especially bloating.

Who Should Use RSP TrueFit?

RSP TrueFit is a great option for people looking for meal-replacement powders and nutrition on the go. Although it is a balanced option in terms of meal-replacements as it contains protein, fat, and carbohydrates, you should always be cautious of consuming these meal replacement options. Whole food sources should always be prioritized.

TrueFit is also great for a high-protein protein powder and can be consumed as pre-workout fuel.

Is RSP TrueFit Safe?

RSP TrueFit is generally safe for consumption, but it does contain whey protein, which is a source of dairy. If you do not consume animal products or are sensitive to dairy, this is not the protein powder for you. Whey protein may cause a loss of appetite, bad taste in the mouth, and digestive discomfort like bloating, constipation, and diarrhea. Additionally, TrueFit might cause digestive discomfort due to the stevia content, although it does not contain a high amount.

How Does RSP TrueFit Compare?

This whey protein powder definitely stands out a bit more as it does not contain a lot of additives or any harmful sugars (many protein powders, especially whey proteins, contain the artificial sweetener sucralose). RSP TrueFit is also quite unique due to its superfood and digestive blend. The MCT powder also provides a healthy fat source that is often missing from other whey protein powders.

Another great whey protein on the market to consider, though, is Vital Proteins Organic Whey Protein. This whey protein is also grass-fed but is a bit more pricey at $44. Vital Proteins is one of the more well-known collagen and whey protein brands on the market today. It also contains 25 grams of protein and 10 grams of collagen. It also contains a natural source of hyaluronic acid for improved athletic performance.

One other whey protein option worth considering is Impact Whey Isolate by My Protein. This product is similar in price at $39.99. It only contains 22 grams of protein per serving but contains 90% protein content, which is pretty good. It is also very low in sugar and carbohydrates, making it a great keto option as well. The only downside is that they do contain sucralose, which is an artificial sweetener. Users really rave about this protein, though, and particularly love the taste and texture.

One final option worth taking a look at would be High Impact Whey Protein. This protein powder was created by Tony Horton and Power Life. It contains 15 grams of whey protein per serving, as well as HMB, vitamin D3, Prohydrolase, Chlorella, and Chromium. Additionally, it includes only 2 grams of carbs, 70 calories, and no sugar.
