delta-E isn’t just an energy boost—it’s a brain-boosting experience. It proprietary, synergistic blend of science-backed ingredients like Suntheanine® and pomegranate extract to support your brain’s focus, clarity, and vitality. While most energy drinks rely solely on sugar and caffeine, delta-E helps your brain function at its best by reducing oxidative stress, supporting healthy neurotransmitters, and promoting mental balance without the crash.

Research shared by Brain Function Specialist Dr. Arlene R. Taylor highlights that ingredients in delta-E—such as pomegranate seed extract and Suntheanine®—have powerful brain benefits:

• They help suppress inflammatory cell signaling and reduce oxidative stress.
  
• They may lower inflammatory cytokines that contribute to cognitive decline.
  
• Suntheanine® (a pure form of L-Theanine found naturally in green tea) supports calm alertness, helping your brain stay relaxed yet focused.
  
  Together, these ingredients help your brain stay sharp, clear, and protected over time.
  

Delta-ETM is an exclusive combination that includes a patented ingredient, Suntheanine®, and a natural caffeine, which produces an energetic beverage (NEB) that allows the alertness-enhancing effects to flow through our bodies while removing or reducing the edgy, jittery, and “jump out of my skin” feelings of other high caffeine and sugar energy drinks. A very recent clinical study from the University of Florida and Harvard Medical School has shown that Suntheanine combined with a special, EGCG-rich green tea extract—similar to that found in delta-ETM—actually has a remarkably positive and protective effect during cold and flu season. Delta-ETM has an exclusive license to combine the only research-proven “L-theanine” with natural caffeine, including
that from green tea extract—in a nutrition energetic drink. Each serving of delta-ETM contains only 75 mg of natural caffeine—delivered EGCG-rich green tea extract- paullinia cupana extract from a South American plant, which is pure natural caffeine.

Absolutely. delta-E is formulated with high-quality, research-supported ingredients that are safe for daily use in healthy adults. It contains no artificial colors, flavors, or preservatives. If you have a medical condition, are pregnant or nursing, or take medications that affect blood pressure or caffeine sensitivity, consult your physician before use.

For best results, take one packet in the morning or anytime you need a mental and physical reset. Mix it with 4–5 ounces of water and drink it slowly. Many people enjoy making delta-E part of their daily reconnection moment—a few minutes to breathe deeply, set intentions, and fuel their focus.
