-
"Probiotics support gut health"
Clinical trials use 6.5-20 billion CFU daily; product doesn't disclose CFU count or strain identity.
PubMed: probiotic clinical trials meta-analysis -
"$29.99 for 30 servings is fair value"
At $1/serving, this is 5-7x the wholesale cost of basic greens powder ingredients ($0.15-0.20/serving).

Claims vs Evidence
MODEST2 of 7 claims supported by evidence.
"Support overall wellness"
Partial
Spirulina and chlorella have antioxidant properties; probiotics may aid digestion. But 70+ ingredients in 7g means most are trace doses.
Based on: spirulina, chlorella, mixed mushroom blend, probiotics
"70+ superfoods"
Stretch
Marketing term; 'superfood' has no regulatory definition. Ingredient count doesn't equal potency or benefit.

"3g fiber per serving"
Supported
3g fiber is modest but real; helps digestion. Not enough to replace a high-fiber diet.
Based on: fiber sources (unspecified)
"Zero sugar"
Supported
Label claim verified; no added sugars detected in marketing materials.
Based on: formulation
"Prebiotics and probiotics support gut health"
Partial

Based on: prebiotics, probiotics
"Digestive enzymes improve nutrient absorption"

Ingredients
Based on peer-reviewed research from PubMed and Examine.com
Blue-green algae with real anti-inflammatory effects. Best evidence for reducing CRP and supporting immune markers.
Research-backed dose: 1-8 g daily based on study doses
Green microalgae with some evidence for modest exercise performance and muscle protein support.
Research-backed dose: 6 g/day (exercise performance studies); 30 g protein equivalent (muscle protein synthesis studies)
Mixed Mushroom Blend
Multi-mushroom blends show early promise for stress, sleep, and immunity, but human evidence is still very limited.
Research-backed dose: No established dose from provided studies
Live bacteria supplements with real benefits for gut health, digestion, and reducing side effects of certain medications.
Research-backed dose: No established universal dose — varies by strain and condition; studies used 6.5 billion CFU/day to 2×10^9 CFU/day
Enzymes that help break down food. Limited human evidence; one trial shows modest protein absorption boost.
Research-backed dose: No established dose from provided studies
Gut-feeding fibers that support digestion, reduce inflammation, and may help with muscle and metabolic health.
Research-backed dose: 5-15 g/day based on study doses
Concentrated fruit and veggie blend. May fill dietary gaps, but no substitute for whole produce.
Research-backed dose: No established dose
fiber sources (unspecified)
Dietary fiber from whole grains may modestly lower LDL cholesterol, but evidence from provided studies is limited.
Research-backed dose: No established dose from provided studies
formulation
A pill coating that bypasses stomach acid, releasing ingredients in the intestine for better absorption or less irritation.
Research-backed dose: No established dose — enteric coating is a delivery technology, not an active ingredient
Medicinal mushroom with early evidence for immune support and COPD management. Most benefits still unproven in humans.
Research-backed dose: No established dose from provided studies
Traditional mushroom with immune and stress effects; promising but limited human trial evidence.
Research-backed dose: 500–1000 mg/day (oral extract, based on limited clinical data)
lion's mane
Medicinal mushroom with early cognitive and mood research, but human evidence is still limited and mixed.
Research-backed dose: 1.8 g daily (limited clinical data; no firmly established range)
Traditional fungus with antioxidant and immune properties, but almost no human clinical evidence and real kidney risk at high doses.
Research-backed dose: No established dose from provided studies
Edible mushroom with immune and antioxidant properties. Human evidence is limited and mixed.
Research-backed dose: No established dose from provided studies
Traditional mushroom used in Asian medicine. Very limited clinical evidence for any health benefit.
