Greens powders are more popular than ever. Two names dominate the market: Athletic Greens (AG1) and Pure Greens. But which product truly delivers on its promises? In this detailed comparison, we take a close look at transparency, ingredients, lab tests, and value for money – so you can make an informed decision.
Important note: Dietary supplements should not be used as a substitute for a balanced and varied diet or a healthy lifestyle.
The Crucial Difference: Ingredient Transparency
The biggest difference between Pure Greens and Athletic Greens lies in transparency. While Pure Greens lists every single ingredient with its exact dosage, AG1 hides behind so-called "Proprietary Blends" – protected mixtures where the exact quantities of individual ingredients are not disclosed.
What does this mean for you as a consumer? With AG1, you don't know how much of which ingredient is actually in the product. You only see the total amount of the blend. This makes it impossible to assess whether the quantities included are even sufficient to achieve an effect.
Pure Greens takes a different approach: complete transparency. Every ingredient is listed with its exact dosage. You know exactly what you're getting – and you can assess for yourself whether the dosages are reasonable.
Comparison Table: Pure Greens vs. Athletic Greens (AG1)
| Criterion | Pure Greens | Athletic Greens (AG1) |
|---|---|---|
| Transparency | ✅ All ingredients with exact dosages | ❌ Proprietary Blends with no precise information |
| Lab Test | ✅ Dr. Graner Lab: 22 pesticides, 7 bacteria, 4 heavy metals | ⚠️ Tests not publicly available |
| Price per Month | ~49€ | ~87€ |
| Reviews | ⭐ 4.82/5 (553 reviews on Trustpilot) | Varies by platform |
| Portions Sold | Over 3 million | Not public |
| Manufacturing | Germany | New Zealand |
Ingredients in Detail: What's Really Inside?
Both products contain a wide range of ingredients – from greens to vitamins, adaptogens, and probiotic cultures. However, the difference lies in traceability.
Pure Greens: Full Ingredient List
Pure Greens contains, among other things:1
- Spirulina – helps to feel more energetic2
- Vitamin C – contributes to the reduction of tiredness and fatigue3
- Zinc – contributes to the normal function of the immune system4
- Ginger – helps support digestion5
- Turmeric – helps support normal liver function6
- Chlorella, barley grass, wheatgrass
- Broccoli, spinach, kale
- Ashwagandha, Rhodiola
- Probiotic cultures
Each individual ingredient is listed with its exact quantity. This allows you to compare the dosages with scientific studies and assess for yourself whether the quantities are sufficient.
Athletic Greens (AG1): The Proprietary Blend Problem
AG1 groups its ingredients into various blends such as "Alkaline, Nutrient-Dense Raw grøntsager Complex" or "Nutrient Dense Extracts, Herbs & Antioxidants". The problem: You only see the total amount of this blend, but not the individual dosages.
For example: If a blend contains 5,000 mg and includes 20 ingredients, theoretically one ingredient could make up 4,900 mg and the remaining 19 just 5 mg each – which would be far too little to have an effect. You simply don't know.
Lab Tests: Quality and Safety
Greens powders contain plant-based ingredients that can potentially be contaminated with pesticides, heavy metals, or bacteria. This is why independent lab tests are crucial.
Pure Greens: Dr. Graner Lab Certification
Every batch of Pure Greens is tested by Dr. Graner Lab in Germany. The tests include:7
- 22 different pesticides
- 7 bacterial contaminants
- 4 heavy metals (lead, arsenic, cadmium, mercury)
The test results are communicated transparently. This gives you the assurance that you are receiving a clean, tested product.
Athletic Greens: Non-Transparent Testing Procedures
While AG1 advertises that the product is tested, the specific test results or certificates are not publicly accessible to consumers. It remains unclear exactly which parameters are tested and what the results are.
Price-Performance Ratio: Where Do You Get More for Your Money?
For a product you take daily, price plays an important role. Let's look at what you get for your money.
Pure Greens: A one-month supply (30 servings) costs around 49€. This equates to approximately 1.63€ per serving.
Athletic Greens (AG1): A one-month supply costs approximately 87€. That's about 2.90€ per serving.
Pure Greens is almost 44% cheaper than AG1 – with better transparency and verifiable lab tests. Over a year, you save over 450€ with Pure Greens.
Taste and Application
A greens powder can be formulated perfectly – but if you don't take it regularly, it's useless. That's why taste is an important factor.
Pure Greens was deliberately developed not to taste like grass. The blend is mild and can be easily mixed into water, smoothies, or plant-based milk. Many users report that they can drink it daily without problems.
Athletic Greens has a distinctive taste that is polarizing. Some like it, others find it takes some getting used to. The vanilla note is clearly noticeable.
Both products can be prepared in about 30 seconds – simply stir into 300-400ml of liquid.
Customer Reviews: What Do Real Users Say?
Pure Greens has a rating of 4.82 out of 5 stars on Trustpilot from 553 reviews. This is an exceptionally high value that speaks to consistent quality and customer satisfaction. Over 3 million servings have already been sold.8
Athletic Greens also has many positive reviews, but these fluctuate more depending on the platform. The high cost is often cited as a disadvantage in many reviews.
