Zena Nutrition Offerings
Liquid Collagen Peptide + Biotin
Liquid Collagen Peptide + Biotin may support your skin structure, hair strength, and nail integrity. The formula features Verisol® Bioactive Collagen Peptides, which may act as building blocks for new collagen formation in the dermis. It could help stimulate fibroblasts, the cells responsible for producing collagen, elastin, and hyaluronic acid. This process may help support skin elasticity, hydration, and overall firmness, which can influence the visible depth of wrinkles over time.
The makers also added biotin in this formula, which works as a coenzyme in carboxylase enzymes, which are involved in fatty acid synthesis, amino acid metabolism, and energy production. It could support keratin infrastructure that makes up hair and nails.
Organic Supergreens Stickpack
According to the official website, Organic Supergreens Stickpack can help you support your intake of phytonutrients, fiber, vitamins, and minerals. The formula includes oat grass, which could support normal bowel movement patterns by adding bulk to stool and helping maintain microbial balance in the gut.
The stick pack also has barley grass, which is a source of vitamins such as vitamin A precursors, vitamin C, and certain B vitamins, along with minerals and plant enzymes. It also contains soluble and insoluble fiber that can help slow digestion and support more stable blood glucose responses, while insoluble fiber supports intestinal motility.
Supergreens Stickpack also has broccoli, which might support your body’s natural detoxification pathways by influencing phase II liver enzymes. It also contributes vitamin C and fiber, which might support immune function and digestive health.
The makers also added carrot, which provides beta-carotene that can be converted into retinol, which supports normal cell differentiation and immune function. Carrots also contain dietary fiber, which contributes to digestive regularity and may support a balanced gut microbiome.
Creatine Monohydrate + D3/K2
Creatine Monohydrate + D3/K2 might support muscle performance, bone metabolism, and cellular function. The formula creatine monohydrate, which helps regenerate adenosine triphosphate (ATP). Creatine also supports strength output, power production, and muscle recovery between sets or repeated efforts. It is also present in brain tissue, where it contributes to cellular energy balance, particularly during periods of increased cognitive demand.
The makers also added vitamin D3 in Creatine Monohydrate + D3/K2, which might support calcium and phosphorus absorption in the intestines. It influences gene expression involved in bone remodeling and immune regulation.
As per the official website, Creatine Monohydrate + D3/K2 also has vitamin K2, which works alongside vitamin D3 by helping direct calcium to bones rather than soft tissues. It activates proteins such as osteocalcin, which might support bone strength and structural integrity.
The formula also has cauliflower powder, which provides naturally occurring fiber, vitamin C, and plant compounds such as glucosinolates. These compounds break down into biologically active metabolites that support the body’s detoxification enzyme systems.
Zena Supergreens + Energy + Hydration
According to the official website, Zena Supergreens + Energy + Hydration supports daily nutrient intake, fluid balance, and sustained energy. It contains green cabbage powder, which contains glucosinolates that may help regulate detoxification enzymes in the liver. Green cabbage also provides fiber, which supports bowel regularity and gut microbial balance, along with vitamin C, which contributes to antioxidant defense and immune cell function.
The formula also combines celery powder, which might support fluid balance, nerve transmission, and muscle contraction. It could also help regulate hydration status and support normal cardiovascular and muscular function. Celery also contains antioxidant compounds that help counter oxidative stress generated during physical activity.
The makers also added green bell pepper powder in Zena Supergreens + Energy + Hydration, which provides vitamin C and carotenoids. Coconut water powder in this formula is a source of electrolytes like potassium and sodium. Electrolytes regulate osmotic balance across cell membranes and are essential for maintaining hydration, especially when you lose fluids through sweat.
Zena Nutrition Advantages
Certified Organic Brand Identity
Zena Nutrition states that its products are made with USDA Certified Organic ingredients, placing its formulations within a regulated organic sourcing framework. USDA organic standards are designed to limit the use of certain synthetic agricultural chemicals and genetically modified inputs during cultivation and processing.
The company also reports that its formulas combine more than 70 plant-based ingredients, including fruits, vegetables, herbs, digestive enzymes, and probiotics. The brand focuses on agricultural traceability and ingredient origin rather than laboratory-derived alternatives. This organic-focused positioning can provide clearer expectations around how ingredients are grown and handled, which may help you feel more confident about sourcing practices and reduce concerns related to synthetic agricultural exposure.
Inclusive Brand Positioning
Zena Nutrition states that its Supergreens products are gluten-free, dairy-free, soy-free, non-GMO, and sugar-free. The company explains that wheatgrass and barley grass are harvested before the grain sprouts, a stage at which gluten-forming components have not yet developed.
The brand further reports that it tests 100% of the finished blend to meet FDA gluten-free standards of less than 20 ppm. The formula excludes dairy, soy, eggs, and gelatin, strengthening its allergen-free positioning. It also states that the product contains no added sugars and no genetically modified ingredients. This approach can make it easier to assess compatibility with your dietary restrictions, while the early harvesting method and finished-product testing may provide added reassurance beyond a standard gluten-free label.
Omnichannel Retail Presence
Zena Nutrition claims that its products are available through multiple retail channels beyond its own ecommerce website. The brand also lists its products on major online marketplaces such as Amazon, Walmart, and Vitacost. Retailers such as Vitamin Shoppe also feature select Zena Nutrition products. This multichannel distribution expands reach and reduces dependence on a single platform, which offers flexibility. You can compare prices, shipping times, and subscription options across retailers. You may also use platform-specific benefits such as loyalty programs or bundled offers. This broad availability may make purchasing and reordering more convenient based on your preferred shopping method.
Zena Nutrition Limitations
Undisclosed Probiotic Potency Metrics
Zena Nutrition does not disclose the total CFU count per serving or the potency of individual strains on its product label or website. Without this information, the strength of the probiotic component remains unclear.
The brand also does not specify how much of the blend consists of live probiotic organisms. As a result, you cannot determine the actual dosage per serving or compare it to clinically studied ranges.
This lack of quantified potency limits transparency and makes it difficult to evaluate the formula’s potential effectiveness. You cannot accurately assess whether the product delivers a meaningful probiotic dose or determine if it aligns with your digestive or immune support goals.
Limited Brand-Specific Clinical Validation
Zena Nutrition does not publish or reference any brand-conducted clinical studies for its finished formulas on its website. It does not present human trials performed on its specific completed formula.
Studies on standalone ingredients do not confirm how a blended formula performs once combined. Without proprietary clinical testing, the real-world performance of the finished product remains unverified.
This limitation means there is less formula-specific outcome data available to evaluate effectiveness. If you prefer products supported by published human trials on the exact formulation you are using, this lack of validation may make it more difficult to assess expected results with confidence.
Zena Nutrition Alternatives
Supergreen Tonik
As per its official website, Supergreen Tonik is centered on its Greens powder positioned as a comprehensive daily formula supporting immunity, energy, focus, sleep, and stress balance. Zena Nutrition, on the other hand, maintains a broader catalog that includes Organic Supergreens in tub and stickpack formats, Supergreens Capsules, Liquid Collagen + Biotin, Creatine Gummies with D3 & K2, and a Supergreens + Energy + Hydration formula.
Supergreen Tonik focuses exclusively on its powdered greens formula, offered in 1-month, 3-month, and 6-month supply options. Its pricing begins at $87 for one month, with bulk pricing lowering the cost to approximately $2.09 per serving in the 6-month bundle. Meanwhile, Zena Nutrition lists at least core products, with its Organic Supergreens Tub priced around $29.99 to $32.99 for 30 servings, and Liquid Collagen + Biotin typically ranging from $34.99 to $44.99 depending on promotional pricing.
Ingredient transparency represents a key structural difference. Supergreen Tonik provides individual dosage disclosure for its ingredients, including Spirulina, Chlorella, Kale, Spinach Leaf, Astragalus, and Elderberry Fruit Extract. The brand explicitly states that it does not use proprietary blends and emphasizes full label disclosure. On the other hand, Zena Nutrition’s Supergreens formula is described as a proprietary blend containing 70+ superfoods, including ashwagandha powder, digestive enzymes, prebiotics, probiotics, fiber blends, hydration blends, and a super mushroom blend. However, individual standardized active compound levels are not specified on the main product page.
Supergreen Tonik integrates greens with adaptogens and nootropics, positioning the product to support cognitive performance and stress response in addition to immune and energy support. Ingredients such as l-theanine, bacopa, rhodiola, and eleuthero align with this positioning. Zena Nutrition highlights that its Supergreens places a stronger emphasis on organic certification and digestive support, highlighting USDA Certified Organic status, zero sugar claims, and the inclusion of digestive enzymes and probiotic blends.
Manufacturing and quality assurance show some overlap. According to their official website, both brands state that their products are made in the United States and undergo third-party testing. Supergreen Tonik additionally emphasizes that it contains no GMOs, dairy, soy, caffeine, or toxins. Meanwhile, Zena Nutrition highlights third-party laboratory testing for safety, quality, and purity, along with globally sourced ingredients.
Supergreen Tonik operates as a single-product, dosage-transparent greens brand with a performance-oriented formulation. Zena Nutrition functions as a diversified company offering multiple categories, organic positioning, and varied delivery formats, extending beyond greens into collagen and creatine formulas.
Amazing Grass
Amazing Grass operates with a broader catalog structure. The portfolio extends across multiple subcategories, including Super Greens, Sweet Greens, Kidz formulas, Protein + Probiotics blends, Wheat Grass powders, capsules, and fizzy green tablets. In comparison, Zena Nutrition presents a narrower category framework built around Supergreens, Creatine, and Collagen. Its range includes Organic Supergreens Stickpack, Zena Supergreens + Energy + Hydration, and Liquid Collagen + Biotin. The variety is more concentrated, with fewer total SKUs than Amazing Grass.
The brands also differ in how they structure functionality within their greens offerings. Amazing Grass segments its products into targeted blends such as Immunity Elderberry, Mood Passionfruit Citrus, Detox & Digest Clean Greens, and multiple Energy variations, including Watermelon and Lemon Lime. Labeling frequently highlights attributes such as Plant-Based, Non-GMO, Gluten Free, No Sugar Added, and Vegan, with one noted exception where a Vitamin D source from lanolin prevents a vegan claim.
On the other hand, Zena Nutrition consolidates multiple functional elements into a single Supergreens formula. The brand emphasizes USDA Certified Organic ingredients, 70+ superfoods, 0g of sugar, 3g of fiber, and the addition of digestive enzymes, prebiotics, probiotics, fruits, vegetables, and a mushroom blend. Rather than distributing these features across separate options, Zena integrates them within one primary greens product, supplemented by an Energy + Hydration variant.
Organic positioning represents another contrast. Amazing Grass offers select organic products, such as Organic Supergreens Powder and Organic Wheat Grass Powder, but organic certification is not applied uniformly across the portfolio. Meanwhile, Zena Nutrition highlights USDA Certified Organic status prominently for its Supergreens line and frames this certification as a central differentiator. The company also states that products are manufactured in the United States in cGMP-certified facilities and are independently third-party tested.
Format diversity further distinguishes the two brands. Amazing Grass provides powders, capsules, fizzy tablets, protein blends, and child-focused options, creating multiple delivery formats within the greens and plant-based space. Meanwhile, Zena Nutrition offers powders in tub and stickpack formats, liquid collagen, and creatine gummies with added vitamins D3 and K2. While Amazing Grass expands primarily within plant-based greens and related blends, Zena extends into adjacent categories such as collagen and creatine.
Amazing Grass offers a diversified, flavor-driven product range with multiple functional blends and demographic-specific options. Zena Nutrition features a more streamlined portfolio supported by complementary collagen and creatine products.

- The brand states that its products are manufactured in cGMP-certified facilities.
- Claims third-party testing for quality and purity.

How Did We Evaluate?
Real User Experiences
To understand user experiences, we looked for what people shared on Amazon for the brand’s key offerings. Liquid Collagen has a 4.4 rating from 2,000+ reviews. Many users claimed they noticed stronger nails, smoother-looking skin, and reduced hair shedding within a few weeks of consistent use. Several also highlighted the convenience of the liquid format compared to pills or powders, stating it was easy to mix with water or juice and simple to include in a daily routine. However, a few customers noted that the formula contains only collagen Types I and III, expressing concern about the absence of additional collagen types for joint or connective tissue support.
Super Greens Powder holds a 4.3 out of 5 rating from 1,800+ reviews. Many users highlighted that it tastes significantly better than other green powders they had tried. Many users claimed to notice improvements in digestion, regularity, and energy levels. However, some customers noted that the sweetness was stronger than expected when mixed with water alone.
Based on this feedback, Zena Nutrition’s key formulations seem to provide support in terms of ease of use, flavor, and perceived effects. However, ingredient transparency and broader formulation scope remain areas of concern.
Brand Credibility
Zena Nutrition offers organic super greens powders, collagen and biotin formulations, and creatine formulas. We examined external reputation indicators, including the presence of the brand on third-party review and business transparency platforms, to evaluate its credibility.
At the time of writing this review, there appears to be minimal presence of the brand on Trustpilot, the Better Business Bureau (BBB), or Tenereteam. There are no publicly accessible independent ratings, complaint histories, or verified consumer reviews available through these sources. The absence of these listings limits the availability of external validation regarding customer satisfaction or dispute resolution patterns. The limited presence represents a gap in publicly verifiable feedback, which makes it challenging to understand the brand’s overall credibility.
Frequently Asked Questions
The brand states that its products are manufactured in the United States using globally sourced, USDA-certified ingredients and that they are third-party tested. However, it does not disclose specific farms, regions, countries, or supplier-level traceability.
No. The brand provides basic daily-use guidance for its products, like recommending one stick pack of Organic Supergreens mixed with 10–12 oz of cold liquid for ongoing use. However, it does not outline structured long-term protocols, cycling schedules, duration limits, or condition-specific monitoring beyond general medical disclaimers.
No. The brand emphasizes organic whole-food powders and third-party testing, but it does not disclose standardized active marker levels such as specific percentages of curcuminoids or saponins. Botanicals are grouped into complexes with total milligram amounts, without individual active standardization details.
Conclusion
Zena Nutrition emphasizes multi-ingredient blends and references third-party testing as part of its quality framework. However, the brand does not publish clinical trials conducted on its finished formulations, meaning the available evidence reflects ingredient-specific research rather than validation of the combined blends themselves.
Zena also does not clearly disclose probiotic strain identification and colony-forming unit counts, which limits assessment of microbial potency and strain relevance. When considering Zena Nutrition and its offerings, you should evaluate the total intake of fat-soluble vitamins such as D3 and K2 if you use multiple products.
If you prioritize certified organic sourcing, integrated formulations, and portable delivery systems, the brand may align with your preferences. However, the limited availability of strain-specific probiotic data and the absence of published clinical trials on the final blended products remain important considerations.
