The Research and Science Behind Microencapsulated Caffeine

Updated on March, 16, 2015

Caffeine is a powerful stimulant. We use Microencapsulation Technology to release the caffeine in Limidax over an extended period of time (XR = extended release), and not all at once. This way, you do NOT experience a massive burst followed by a major downfall in energy in a short-period of time. The ingredient has a very successful track record of scientific and clinical studies showing health benefits from short-term to long-term use (studies with Caffeine and Alzheimer's, cirrhosis, and liver cancer). Caffeine supplement is in our study pill as a nootropic, because research has shown that it boosts brain function, focus, attention, mental performance, and stamina on demanding tasks.



Why Caffeine is in our Limidax Extended Concentration Proprietary Blend

Limidax XR microencapsulated caffeine is a one-of-a-kind caffeine delivery system which has been designed to mask the bitter taste of caffeine and provide a sustained energy release, ideal for studying and completing tasks. Consuming caffeine in traditional forms, such as tea and coffee, leads to rapid absorption, making its stimulating effect rapid and transitory, and is prone to cause side-effects. Microencapsulated caffeine however, overcomes these defects. Limidax XR even goes above and beyond by also using L-theanine, known for its synergistic effects with caffeine.

Limidax XR uses LIMIDAX Smart Dosing™ Microencapsulation Technology to deliver maximum focus benefits. Our innovative approach allows for a sustained release profile along with improved delivery. Our multiple targeted release points enables Limidax to start working within 30 minutes to an hour after consumption, while also lasting up to 12 hours!



Effects of Caffeine on Cognitive Performance

An increase in concentration and focus was noted in a double-blind, randomized study involving 72 people.

Caffeine taken with glucose (sugar) had beneficial effects on attention (sequential reaction time tasks) and on learning and consolidation of verbal memory. The change of effects were statistically significant (p-value < 0.05). You can read the full study yourself through The U.S. National Library of Medicine



Benefits of Caffeine versus Placebo on Verbal, Motor and Perceptual Memory

Caffeine increased memory relative to placebo in regards to perceptual memory. This was noted in a double-blind study involving 61 people.

The change of effects were statistically significant (p-value < 0.05). You can read the full study yourself through The U.S. National Library of Medicine

Positive Caffeine Effects: Increased Mental Reaction and Processing Speeds

An increase in mental reaction and processing speeds was noted in double-blind, placebo-controlled experiment with 64 healthy college students.

The change of effect was statistically significant (p-value < 0.05). The 64 subjects were given a continuous performance standardized test, called the Test of Variables of Attention (TOVA). Caffeine consumption led to significantly faster response times. You can read the full study yourself through The U.S. National Library of Medicine

Subjective, Behavioral, and Physiological Effects of Acute Caffeine

An increase in performance on working memory was noted in double-blind experiment with 102 people.

Caffeine also increased the number of hits and increased attention in a vigilance task. The change of effects were statistically significant (p-value < 0.05). Furthermore, no significant interactions on euphoria or desire of "more drug" were noted as were with amphetamine. The scientists agreed, "We confirm that acute doses of caffeine ... produce stimulant-like subjective effects and enhance performance."
