CompleteGreens™ (NNB Nutrition) is a comprehensive greens base blend designed as a formulator ingredient for supplement brands building greens powders, superfood blends, and daily wellness products. Unlike MitoGreens® (mitochondria-focused) or standard token greens ingredients, CompleteGreens™ provides broad-spectrum coverage of vegetable, fruit, algae, and botanical categories for complete phytonutrient support. As a B2B ingredient designed for manufacturers, CompleteGreens™ allows brands to include a research-backed, standardized greens complex without developing their own blend.

Studied Dose 3–8g/day comprehensive greens blend; specific CompleteGreens™ dosing per NNB product specifications and formulation guidelines
Active Compound Proprietary comprehensive greens blend — typically includes wheatgrass, barley grass, spirulina, chlorella, spinach, kale, broccoli, and related vegetable/algae sources; NNB CompleteGreens™ specific formulation proprietary

Benefits

Complete phytonutrient and micronutrient coverage

A comprehensive greens blend provides a wide range of fat-soluble vitamins (A, K1, K2, E), water-soluble vitamins (folate, B vitamins, C), trace minerals (iron, zinc, magnesium), and thousands of phytochemicals (flavonoids, carotenoids, chlorophyll, glucosinolates) in a single convenient ingredient — addressing common micronutrient gaps in modern diets.

Alkalizing and pH balance support

High-protein and high-carbohydrate diets, intense exercise, and modern processed food consumption all contribute to mild metabolic acidosis. Concentrated greens blends provide a strong alkalizing effect through mineral-rich plant foods and organic acids that buffer excess dietary acid load, supporting kidney function, bone mineral retention, and overall metabolic health.

Immune and antioxidant support

Spirulina, chlorella, and cruciferous greens provide beta-glucans, phycocyanin, sulforaphane precursors, and concentrated chlorophyll — compounds with documented immune modulation, NK cell activation, and antioxidant enzyme induction activity. Regular greens consumption is associated with reduced all-cause mortality in large epidemiological studies.

Mechanism of action

1

Nrf2 activation and phase II enzyme induction

Cruciferous vegetables in greens blends (broccoli, kale, cabbage) provide glucoraphanin — converted to sulforaphane by myrosinase — which potently activates the Nrf2/ARE pathway. This master antioxidant switch upregulates glutathione synthesis (GCL, GSS), Phase II detoxification enzymes (NQO1, HO-1), and antioxidant response genes that protect cells from oxidative and chemical stress.

Clinical trials

Greens Powder Supplementation and Health Markers — Limited Clinical Evidence
PubMed

There is no specific clinical trial of CompleteGreens™ as a standalone branded ingredient indexed in PubMed. The category 'greens powders' has been studied in a small number of trials; effects depend heavily on the specific blend. The cited PMID 15212482 may be an indirect or unrelated reference.

Pooled across general 'greens powder' literature.

Some greens powder trials show modest improvements in serum antioxidant capacity, modest BP reductions (3-5 mmHg in one trial), and reduced oxidative stress markers — but these effects are typically attributable to underlying high-content components like beetroot (nitrate), spirulina, or specific polyphenol-rich fruits/vegetables, NOT mysteriously additive. Buying a 'greens powder' for blanket health benefits has weaker evidence than supplementing the specific established ingredients (e.g., a verified beetroot extract for BP, fish oil for cardiometabolic).

Side effects and drug interactions

Common Potential side effects

Generally very well tolerated
GI adjustment (bloating, gas) common in first 1–2 weeks — start with half serving
Check for allergens (gluten in wheatgrass, soy in some blends)
Vitamin K content relevant for anticoagulant users

Important Drug interactions

Warfarin — vitamin K in greens blends may affect INR; maintain consistent greens intake and monitor
Thyroid medications (levothyroxine) — goitrogens in raw cruciferous greens; take thyroid medication separately from greens
Iron absorption — chlorophyll and oxalates may reduce iron absorption; take iron supplements separately
