S7™
Endogenous Nitric Oxide Synthesis Stimulation
The primary proposed mechanism of S7™ is the upregulation of endogenous nitric oxide (NO) production via the endothelial nitric oxide synthase (eNOS, EC 1.14.13.39) pathway. S7™ is a blend of seven plant-based ingredients: green coffee bean extract, green tea extract, turmeric extract, tart cherry, blueberry, broccoli, and kale. These ingredients are rich in polyphenolic compounds, such as chlorogenic acid (from green coffee), epigallocatechin gallate (EGCG, from green tea), curcuminoids (from turmeric), and anthocyanins (from berries).
Polyphenols are known to activate eNOS through several signaling cascades. A key pathway involves the activation of phosphatidylinositol 3-kinase (PI3K), which in turn activates the protein kinase Akt (also known as Protein Kinase B). Activated Akt can then phosphorylate eNOS at a specific serine residue (Ser1177 in human eNOS), which significantly increases its enzymatic activity. This phosphorylation event enhances the enzyme's affinity for its cofactor, calmodulin, and increases the rate of electron flow from its reductase domain to its oxygenase domain, where L-arginine is converted to L-citrulline and NO.
By stimulating this pathway, S7™ aims to increase NO bioavailability without providing exogenous NO precursors like L-arginine or nitrates. The resulting increase in NO concentration in the vascular endothelium leads to the activation of soluble guanylate cyclase (sGC) in adjacent smooth muscle cells. This enzyme catalyzes the conversion of guanosine triphosphate (GTP) to cyclic guanosine monophosphate (cGMP). Elevated cGMP levels then activate protein kinase G (PKG), which phosphorylates several downstream targets, leading to a decrease in intracellular calcium concentrations and the relaxation of the smooth muscle cells. This process, known as vasodilation, widens the blood vessels, reduces blood pressure, and increases blood flow.
Pharmacokinetics
The provided sources do not contain specific pharmacokinetic data for the S7™ blend, such as Tmax, bioavailability, or half-life. The pharmacokinetics would be complex, representing the aggregate absorption, distribution, metabolism, and excretion of the various polyphenols from the seven constituent ingredients. Generally, polyphenols have variable and often low bioavailability, but their metabolites may exert biological activity.

Everything About S7™ Article
S7™: The Low-Dose Plant-Based Nitric Oxide Booster
In the world of sports nutrition, the quest for a better muscle pump is relentless. The 'pump' isn't just a fleeting feeling of satisfaction in the gym; it's the physiological result of increased blood flow, or hyperemia, which floods your muscles with oxygen and nutrients. S7™ is a branded, low-dose blend of seven plant-based ingredients that has gained popularity in pre-workout formulas for its purported ability to dramatically increase nitric oxide (NO), the body's master vasodilator.
What It Does: Triggering Your Body's Own NO
Unlike many nitric oxide boosters that work by providing the body with raw materials like L-Citrulline or nitrates, S7™ takes a different approach. It's designed to be a trigger, signaling your body to produce more of its own nitric oxide.
The key benefits stem from this increase in NO: Vasodilation: NO signals the muscles in your blood vessel walls to relax, causing them to widen. Increased Blood Flow: Wider blood vessels allow more blood to flow through them. Enhanced Nutrient Delivery: This increased blood flow acts like a superhighway, delivering more oxygen, glucose, and amino acids to your muscles during a workout. The 'Pump': The result of this process is the full, tight feeling of a muscle pump that athletes chase.
The Science: How Does S7™ Work?
S7™ is a proprietary blend of green coffee bean extract, green tea extract, turmeric extract, tart cherry, blueberry, broccoli, and kale. The power of this blend lies in its rich concentration of polyphenols—bioactive compounds found in plants.
These polyphenols are thought to work by stimulating an enzyme called endothelial nitric oxide synthase (eNOS). Think of eNOS as the factory inside your blood vessels that produces nitric oxide. S7™ acts like a foreman, telling the factory to ramp up production. This is different from ingredients like L-Citrulline, which is like delivering more raw materials to the factory door. By directly stimulating the enzyme, S7™ can achieve a significant boost in NO from a very small dose.
What The Research Says
The clinical evidence for S7™ is currently based on a single pilot study conducted by its manufacturer, FutureCeuticals. While this should be viewed with a critical eye, the results are intriguing.
The S7™ Pilot Study: Design: A double-blind, placebo-controlled, crossover study. Participants: 8 healthy adults (aged 24-55). Dose: A single 50mg dose of S7™. Finding: The study reported that the 50mg dose of S7™ led to a 230% increase in circulating nitric oxide levels compared to the placebo.
It is crucial to note that this was a small (N=8) study and has not been published in a peer-reviewed journal. The evidence is therefore considered limited and preliminary. More independent, large-scale research is needed to confirm these findings.
Dosing Guide
Clinically Studied Dose: The pilot study used a single dose of 50mg. Common Product Dose: A survey of products containing S7™ shows a typical range of 50mg to 100mg per serving. Red Flag: Be cautious of products that list S7™ in a proprietary blend or contain less than 50mg, as this is below the dose used in the manufacturer's study.
Forms Compared
S7™ is a trademarked, specific blend. There is no generic equivalent. When you see S7™ on a label, you are getting the exact combination of seven ingredients used in the study. You cannot buy the components separately and expect the same synergistic effect.
When & How To Take It
S7™ is almost exclusively found in pre-workout supplements. For best results, it should be consumed 20-30 minutes before exercise as part of your pre-workout drink. This timing allows the ingredients to be absorbed and begin stimulating nitric oxide production as you start your training.
Stacking S7™
S7™ stacks very well with other common pre-workout ingredients: L-Citrulline: This is a powerful synergy. L-Citrulline provides the fuel for NO production, while S7™ stimulates the enzyme that uses that fuel. Combining them may produce a much greater pump than either one alone. Glycerol: For a 'hyper-hydration' pump, stacking S7™ with a glycerol product can draw water into the muscles while S7™ increases blood flow, creating an intense, water-based pump. Creatine: Enhanced blood flow from S7™ can help deliver creatine and water to the muscles more efficiently.
Who Should Take It
S7™ is ideal for: Athletes and gym-goers seeking enhanced muscle pumps during workouts. Individuals looking for a low-stimulant or stimulant-free pre-workout boost. People who prefer a nitrate-free approach to increasing nitric oxide.
Who Should NOT Take It
Individuals on medication for high or low blood pressure should consult their doctor before using any supplement that affects vasodilation. Anyone with a bleeding disorder or scheduled for surgery should avoid S7™. There is no safety data for pregnant or breastfeeding women.
The Bottom Line
S7™ is a promising, innovative ingredient for enhancing nitric oxide and muscle pumps. Its key advantages are its plant-based origin, nitrate-free mechanism, and low effective dose of just 50mg. While the evidence is currently limited to a small, industry-funded study, the 230% increase in NO is a compelling claim that has led to its inclusion in many popular pre-workout formulas. For those seeking a better pump, S7™ is an ingredient worth looking for on a supplement label.
