“Consuming a balanced diet rich with essential vitamins and minerals can be key for athletes looking to support energy production, muscle function, immune health and overall well-being,” states Dr. Raj Dasgupta, MD. (1) To fill any present gaps in your diet, the best greens powders, like Transparent Labs Prebiotic Greens, can be beneficial in delivering vital macro- and micronutrients in a convenient, tasty beverage. (2)
In our opinion, Transparent Labs Prebiotic Greens can be a valuable part of your regimen, thanks to its third-party tested makeup, impressive fiber content, and multiple flavor profiles. However, some minerals may be underdosed when it comes to your specific needs. In this Transparent Labs Prebiotic Greens review, our team of experts examined this popular greens powder in terms of formulation, taste, solubility, and overall value, employing our supplement testing methodology, similar to our trials with over 50 other greens supplements in the past. Now, let’s grab our trusty shaker bottles and get into our findings.
A simple but effectively-dosed supplement that emphasizes sea greens and prebiotic fiber, and contains other ingredients in full doses backed by science.

In terms of formula, Transparent Labs Prebiotic Greens comes with a handful of common ingredients, like organic spirulina and chlorella, two algae greens sources that studies say can promote better antioxidant status and immune function within the body. (4)(5) “Transparent Labs sets this powder apart from other greens powder supplements, though, thanks to the up to 6 grams of dietary fiber per serving,” notes Chelsea Rae Bourgeois, registered dietitian nutritionist and BarBend expert contributor. “You also get 4 grams of protein per serving, and every ingredient dosage is listed accurately without the use of proprietary blends.”
As far as the delivered minerals, each serving includes calcium, iron, phosphorus, magnesium, potassium, and sodium. According to the Food and Drug Administration, though, these servings aren’t particularly excessive — only the 25 milligrams of magnesium is higher than 5% of your daily value. (6) If you’re looking to dial in your vitamin and mineral intake in one fell swoop, it may be best to look for one of the best multivitamins for more nutrient-dense formulations.
Despite the lack of mineral content per dose, we do enjoy the 3 grams of prebiotic fiber per single-scoop serving. Prebiotic fibers (like the organic green banana flour and organic Jerusalem artichoke fiber used in this makeup) can be beneficial in feeding your gut microbiome, which can be helpful in supporting your gut health and serving as a fuel source for probiotics. (3) “Probiotics are live bacteria that live within your body and can be highly influential in supporting your microbiota balance, particularly within the digestive system,” adds Dr. Raj Dasgupta, MD.
Other macronutrient counts for Prebiotic Greens include between 40 and 50 calories and 9 to 10 total carbohydrates per serving, depending on your chosen flavor.
Speaking of tastes, we appreciate that Transparent Labs takes a page from its best tasting protein powders, offering Prebiotic Greens in a range of flavors. While other greens powders are typically available in just one taste, you can find Prebiotic Greens in Original, Peach Mango, and Pineapple Coconut. Regardless of your decision, each formulation is sweetened with stevia — a natural sweetening agent. Studies report, though, that stevia can create an unpleasant aftertaste for some athletes and can potentially lead to GI distress. (7)(8)
Finally, you can purchase Prebiotic Greens for $45.99, or roughly $1.53 per serving. While this is an average cost of greens powders, Transparent Labs also offers a ‘Subscribe & Save’ service that can discount your order total by $5 and unlock free shipping in exchange for your agreement to repeat autoship orders.
Who Should Use / Who Shouldn’t Use Transparent Labs Prebiotic Greens
No two athletes are alike, and their nutritional needs are just as different. As such, while Transparent Labs Prebiotic Greens may be the perfect powder for one individual, others may be better served with another pick from the best fruit and vegetable supplements. Below, we’ve outlined a handful of camps that could benefit greatly from Prebiotic Greens along with a few that may be better off looking elsewhere for filling their present nutrient gaps.
Recommended for:
- Athletes wanting a greens powder with high dietary fiber counts per serving
- Those looking for a greens supplement with multiple flavor options
- People in search of a third-party tested greens powder
Not Recommended for:
- Individuals wanting higher counts of key minerals and other micronutrients
- Athletes averse to stevia as a sweetening agent
- People wanting a more robust ingredients list with to account for more fruit and vegetable servings
Our Experience Using Transparent Labs Prebiotic Greens
The BarBend team of competitive athletes, certified personal trainers, nutrition coaches, and lifelong fitness enthusiasts has tested over 55 different greens powders over the years. We’ve used those findings, along with our supplement testing methodology, to shape our approach to this Transparent Labs Prebiotic Greens review. We carefully examined the dietary supplement in key categories like formulation, solubility, taste, and overall value, among others, rating Prebiotic Greens on a scale of 1 (lowest) to 5 (highest) to give you a clearer indication of its performance.
Ingredients and Formulation
Transparent Labs Prebiotic Greens is gluten-free and non-GMO, which can be beneficial for those following specific dietary restrictions. In addition, we appreciate the simple yet refined ingredients list that doesn’t hide its listed dosages behind proprietary blends. Chelsea Rae Bourgeois, MS, RDN, LD rates the formulation at 4.5 out of 5, stating, “I’m a big fan of the supplement facts with this greens powder that can deliver up to 6 grams of dietary fiber and 4 grams of protein per serving. Plus, there aren’t any artificial sweeteners or preservatives to speak of, meaning you’re paying for actual ingredients rather than unnecessary junk.”
In terms of the “actual ingredients,” we do appreciate the presence of spirulina and chlorella, which may promote reduced inflammation and digestive health. (4)(5) The 3 grams of prebiotic fiber are also nice inclusions given their role in fueling probiotics for improved gut health. (3)
However, the six listed ingredients do limit how many nutrients can be delivered in each serving, and there are no additional probiotic strains to speak of like you’d find in some of the best probiotic supplements. If you’re looking for a more comprehensive blend of ingredients for a more nutrient-dense formulation, it may be best to look elsewhere.
Taste
When it comes to taste, greens powders can often come with an earthy profile that’s (understandably) similar to a grassy flavor. According to our tester, a certified personal trainer, that’s not the case with Prebiotic Greens. “I tried the Peach Mango variety and was pleased with its accurate description,” they note in reference to their 4-out-of-5 flavor rating. “It’s sweet yet not overpowering, and while you do taste the stevia, I didn’t have that normal aftertaste that comes with other similarly sweetened powders.”
Of course, though, we understand that taste can be subjective, and our one tester did say their blend was a little bitter. If you’re worried about your own experience, we suggest the Original, unflavored powder that can be mixed into more complex recipes with varied flavors. For example, you could blend the Original Prebiotic Greens with the best protein powders for smoothies and some of your favorite fruits and vegetables for an all-encompassing, nutrient-dense shake — no grassy profiles to speak of.
Solubility
Of course, with any powdered supplement, you want to ensure it can mix easily in your best shaker bottle. Our tester notes that Prebiotic Greens blends easily in any vessel with no present issues. “There’s no excessive grittiness or clumps with mixing this in a shaker. However, I tend to drink my greens supplements in a single go, so I can’t necessarily speak on any separation when left to sit for excessive periods.” As such, we rate the solubility at 4.5 out of 5.
Price Per Serving
You can find most greens powders for, on average, $1.79 per serving based on our calculations. With a listed cost per serving at roughly $1.53, this does put Transparent Labs Prebiotic Greens amongst the more affordable options in the category. However, we have found multiple greens supplements below this median price tag with more robust formulations, so while the price is budget-friendly, we feel the overall value is closer to mid-range levels. As such, we score the price per serving at a conservative 3 out of 5.
Thankfully, though, there are means to elevate the value in terms of discounts and potential savings. In addition to the multiple Transparent Labs discount codes we’ve been able to find online, the brand also offers a ‘Subscribe & Save’ service that gives you $5 off your order total in addition to free shipping.
Third Party Testing
Like many of the brand’s offerings, including Transparent Labs Grass-Fed Whey Protein Isolate and Transparent Labs Creatine HMB, Prebiotic Greens carries third-party testing from Informed Choice — one of the most recognizable laboratories that tests nutritional supplements for label accuracy and the presence of banned substances. “Having this third-party approval stamp can be a quick way for athletes to identify which greens powders are without any unwanted ingredients,” adds Chelsea Rae Bourgeois, MS, RDN, LD. “It’s some appreciated peace of mind when it comes to purchasing a new supplement for your regimen.”
We also score Prebiotic Greens at 5 out of 5 for the category since the third-party testing results are clearly listed on the product’s retail page. This adds to the reassurance and gives athletes all of the necessary data rather than solely relying on the stamp of approval.
What to Consider Before Buying Transparent Labs Prebiotic Greens
Like any supplement purchase, there are a few factors worth considering before you make your way through checkout. Whether opting for Transparent Labs Prebiotic Greens or another formulation, here are a handful of items worth pondering over as you finalize your decision.
- Quality Ingredients: Greens powders are typically composed of whole-food sourced ingredients like spirulina, leafy greens, chlorella, and others, there can be specific ingredients that better align with your fitness goals and dietary needs. Read through the whole makeup to ensure your powder hits those aspirations as well as aligns with your personal sensitivities or allergies.
- Nutrient Density: While leafy greens — the main ingredients found in greens powders — are some of the most nutrient-dense foods, it’s still important to check the full supplement facts to ensure your supplement adequately delivers key vitamins and minerals at appropriate dosages. Think about your general whole-food intake and compare it to the FDA’s recommended daily values, then look for a greens powder that efficiently fills any present gaps. (6)
- Available Flavors: Green superfood powders have a tendency to be earthy and grassy in flavor, but you can find more intriguing tastes depending on your chosen supplement. This can be beneficial for athletes averse to the grassy, sometimes bitter profile yet still want to use a greens powder to supplement nutrient deficiencies within their diet.
- Value: Most greens powders, on average cost roughly $1.79 per serving with options on both sides of this median depending on factors like third-party testing, included ingredients, and more. When searching for a greens supplement, think about your comfortable spending limit and look for a formulation that aligns with your finances.
Transparent Labs Prebiotic Greens Vs. Competitors
Transparent Labs Prebiotic Greens is not the lone greens supplement on the market, and there are comparable powders out there that can appeal to different needs. Below, we’ve outlined key specs for two popular greens powders we feel match well with Prebiotic Greens — AG1 and Nested Naturals Super Greens.
| Transparent Labs Prebiotic Greens | AG1 | Nested Naturals Super Greens | |
| Price Per Serving | $1.53 | $3.30 | Starting at $0.67 |
| Calories Per Serving | 40-50 | 50 | 30 |
| Carbs Per Serving | 9-10g | 6g | 5g |
| Dietary Fiber Per Serving | 5-6g | 2g | 2g |
| Protein Per Serving | 4g | 2g | 2g |

| Sweeteners Used | Stevia | Stevia | Monk fruit |
| Available Flavors | Original, Peach Mango, Pineapple Coconut | Pineapple Vanilla | Original |
| Third-Party Testing | Informed Choice | NSF Certified for Sport | Certifying lab not listed |
As the quintessential greens supplement, AG1 (or Athletic Greens as some may recognize) is packed with tons of superfoods, herbs, antioxidants, digestive enzymes, and probiotics. We also appreciate the NSF Certified for Sport third-party testing, as well as the comprehensive formulation delivering a wide range of key vitamins and minerals. However, this nutrient-dense formulation is over double the price of Prebiotic Greens, making it a far heftier investment.
Nested Naturals Super Greens, on the other hand, is a budget-friendly powder with prices starting at just $0.67 per serving. This greens supplement also features a blend of probiotic strains and digestive enzymes to support gut and digestive health. However, the listed minerals are less than that of Transparent Labs’ offering, and we would appreciate some further insight on the actual servings of each whole-food ingredient — virtually all listed compounds are hidden behind probiotic blends.
Places to Buy Transparent Labs Prebiotic Greens
Transparent Labs Prebiotic Greens can be purchased online directly from the brand’s retail site. You can also find this popular greens supplement on select third-party retailers, like The Vitamin Shoppe.

Our Final Verdict on Transparent Labs Prebiotic Greens
With its third-party tested formulation, impressive fiber per serving, affordable price point, and available flavors, Transparent Labs Prebiotic Greens can be an effective greens powder option for a wide range of interested athletes. While the micronutrient counts are less than that of other, more fruit-and-veggie-dense formulations, this can be a worthwhile pick for those wanting a greens supplement constructed from clean ingredients without any excessive fillers or synthetic additives. According to our testers, the available flavor options are pretty enticing, too.
When looking to add a greens powder to your daily regimen, be sure to read through the listed ingredients and determine whether your powder of choice can effectively fill the nutrient gaps you’re trying to resolve. We also recommend setting a budget before checkout, since some greens supplements can be expensive at over $3 per serving.
