S7 Complex
Also known as: S7, S7 Blend, Seven Plant Blend
Effective Dosage
50 mg daily (proprietary blend claim; no independent dose-response data available)
What the Science Says
S7 is a proprietary blend of seven plant-based ingredients — including green coffee bean extract, green tea extract, turmeric, tart cherry, blueberry, broccoli, and kale — marketed primarily to fitness consumers. The manufacturer claims it can increase the body's own nitric oxide production by up to 230%, which would theoretically improve blood flow, endurance, and muscle pumps during exercise. However, the only available evidence comes from a single small study funded by the ingredient's manufacturer, FutureCeuticals, making independent verification essentially nonexistent. No dose-response data from independent researchers is available.
What It Doesn't Do
The 230% nitric oxide boost claim is based on one manufacturer-funded study — not independent science. Won't replace proven nitric oxide boosters like citrulline or beetroot extract. No evidence it meaningfully improves athletic performance in real-world conditions. The individual plant ingredients at the doses used are too low to deliver the benefits those plants show in standalone research. Not a substitute for a balanced diet rich in vegetables.
Evidence-Based Benefits
S7 Complex is a blend of seven plant-based ingredients that has been shown to enhance nitric oxide production in the body, potentially improving blood flow and exercise performance. Some studies suggest it may also support endurance and recovery during physical activity.

Absorption & Bioavailability
Unknown — no independent pharmacokinetic studies available for the blend as formulated. Individual components like green tea and turmeric have variable absorption depending on formulation.
Red Flags to Watch For
- All supporting research appears to be funded by FutureCeuticals, the ingredient's manufacturer — a major conflict of interest
- Proprietary blend means exact amounts of each plant ingredient are undisclosed, making it impossible to verify effective doses
- The '230% nitric oxide increase' marketing claim is based on a single small, non-peer-reviewed or industry-funded study
- No independent replication of efficacy claims has been published in peer-reviewed literature
- Frequently used as a label-dressing ingredient at doses too low to match what individual plant extracts show in standalone research
