Nootropic Properties

  • Increases acetylcholine levels in the brain via butyrylcholinsterase (BHCE) inhibition (100-fold greater than acetylcholinesterase (ACHE), leading to enhanced memory and focus (1).
  • Protects the hippocampus against oxidative stress by stabilizing intracellular calcium levels (2).
  • Eckol and dieckol have shown to be potent inhibitors against the activity of MAO-A and MAO-B, which may be helpful for improving mood and cognitive function (3).
  • Protects neurons from oxidative stress (via mitochondrial protection and AChE inhibition (4).
  • Reduces Amyloid-beta plaque, hyperphosphorlated tau and Amyloid Precursor Protein (APP) expression, therefore eliciting a neuroprotective action (5).

Athletic Performance

  • Ecklonia cava can enhance exercise endurance via enhancing oxidation of glucose and less production of lactate during intense exercise, possibly by its free-radical-scavenging and procirculatory activities (6).
  • With a human study, 141 young adults were given a beverage containing 200 mg of Ecklonia cava daily. In two weeks their regular weight dropped nearly 2.5 pounds, muscle mass increased by nearly 2.5 pounds, and body fat dropped by 4 pounds, or 7.48%. ECE stimulates the body to burn fat by increasing muscle mass (7).
  • Ecklonia can reduce weight gain, via ↑ AMPK/SIRT1 and ↑PPAR-α/CPT-1 and ↓SREBP 1 (8).
  • After a six-week study, flow mediated dilation and Nitric Oxide mediated dilation increased by 60% and 50%, therefore improving muscle pump and blood flow (9).
  • EC is a strong follistatin booster and as such myostatin inhibitor, which are critical genes responsible for dictating muscle growth potential (10).


  • Ecklonia cava promotes many of its central nervous system effects via GABAA-BZD receptors (11), therefore enhances sleep quality and efficiency.
  • The polyphenols present in ecklonia are strong potentiators of sleep (12)
  • Triphlorethol A (found in ecklonia) may improve sleep by decreasing sleep latency and increasing non-rapid eye movement (NREM) sleep (13).
  • In animal models, triphlorethol A supplementation (at 50mg/kg) was able to replicate the effects of Zolpidem (ambien 10mg/kg), but unlike ambien, increased the quantity of sleep without reducing sleep quality (triphlorethol A did not effect delta activity) (14).


  • Scientists studied 31 men with erectile dysfunction for over six months. For eight weeks they
    compared ECE to Viagra®. Ecklonia cava outperformed Viagra in terms of orgasmic function, intercourse fulfillment, erectile
    function, and overall fulfillment (15).
  • Ecklonia may also combat dysbiosis, improve intestinal permeability and enhance nutrient absorption (16).
  • When combined with Chitosan and Tribulus terrestris, Ecklonia can improve libido and erectile function in men with lower levels of Testosterone (17).
  • EC may have pain reducing effects and may act similarly gabapentin (18).
  • EC can protect against some Electromagnetic Fields (EMFs) by suppressing cell death from radiation damage and by improving antioxidant levels in cells, thus protecting the cells and DNA from damage (19).

Ecklonia cava is so diverse that I never know where to start when I talk to people about it. It has some sensational research and the physical experience 100% matches it. A long term keeper in my opinion. WORD OF WARNING, most other products are fake, this one uses the standardised form to ensure efficacy.
