Levagen+®: Bioavailability Study

A parallel, double-blind, bioavailability study was conducted with 28 healthy male and female volunteers over 18 years old to measure uptake of Levagen®+ (PEA) over a 24-hour period. The objective of this trial was to determine whether the use of a lipid-based drug delivery system, LipiSperse®, can be successfully used to improve the bioavailability of Levagen®.

Study Results:

The results indicate that by combining Levagen with LipiSperse® delivery system, PEA absorption is more effective.

Levagen+®: Exercise Recovery Study

A double-blind, randomised, placebo-controlled study to evaluate the effect of orally dosed Levagen®+ on exercise recovery in 28 healthy males (18-35 years).

72-hour treatment duration with 2 trial arms: (i) Levagen+ 168mg; and (ii) Placebo

30 minutes after ingestion of product, participants were exercised to induce local leg muscle fatigue using a leg press (4 sets of 80% of 1RM). Participants consumed the supplement again post-workout and dosed once daily for three days thereafter.

Two hours post exercise fatigue the participant again completed 1 set of leg press reps at 70% of maximal until exhaustion to measure performance.

Study Results:

Levagen®+ significantly:

The results suggest that Levagen®+ may allow individuals to train harder and longer than placebo by reducing muscle damage and sparing anaerobic energy metabolism. This allows athletes to push past their limits and improve training response.

Hydrocurc®: Bioavailability Study

A parallel, double-blind, bioavailability study was conducted with 28 healthy male and female volunteers over 18 years old to measure uptake of Hydrocurc® PEA over a 24-hour period. The objective of this trial was to determine whether the use of a lipid-based drug delivery system, LipiSperse®, can be successfully used to improve the bioavailability of Curcuma longa extract (95% curcuminoids).

Study Results:

These results indicate Hydrocurc® to be the most bioavailable curcumin seen in industry to date with the lowest dose.

Hydrocurc® also had the highest loading of Curcuma longa extract (90%) with the lowest load of excipients (10% Lipisperse®).

Hydrocurc®: Exercise Recovery Study

A double-blind, randomised, placebo-controlled study to evaluate the effect of orally dosed Hydrocurc® on exercise recovery in 28 healthy males (18-35 years).

72-hour treatment duration with 2 trial arms: (i) Hydrocurc® 500mg; and (ii) Placebo.

30 minutes after ingestion of product, participants were exercised to induce local leg muscle fatigue using a leg press (4 sets of 80% of 1RM). Participants consumed the supplement again post-workout and dosed once daily for three days thereafter.

Two hours post exercise fatigue the participant again completed 1 set of leg press reps at 70% of maximal until exhaustion to measure performance.

Study Results:

500mg Hydrocurc® significantly:

  1. Reduced lactate levels
  2. Reduced delayed onset muscle soreness (DOMS) [48- and 72-hours post-exercise]
  3. Increased IL-10 (anti-inflammatory)
  4. Reduced thigh circumference (swelling)
  5. Actives the downstream region of the mTOR pathway (Akt/PKB)

These results suggest that Hydrocurc® may allow for a quicker return to exercise training or ability to exercise higher thresholds. This may be due to an interaction between IL-6 and IL-10 eliciting anti-inflammatory properties which reduce thigh circumference, pain, and modulate energy metabolism.

Activation of mTOR pathway also indicates Hydrocurc® to be a potential stimulator of muscle hypertrophy.

Hydrocurc®: Cognitive Health Study

A 6-week double-blind, randomised, placebo-controlled study to study the effects of co-administering oral iron supplementation with HydroCurc® on serum BDNF levels and ferritin levels.


180 healthy adults (18-40 years) across 5 groups:

  1. Curcumin placebo + iron placebo
  2. 18mg elemental iron + curcumin placebo
  3. 18mg elemental iron + 500 mg HydroCurc®
  4. 65mg elemental iron + curcumin placebo
  5. 65mg elemental iron + 500 mg  HydroCurc®

* >50mg iron = pharmaceutical dose

Study Results:

HydroCurc® +18mg Iron group had:

These results indicate that co-administrating HydroCurc® with 18 mg elemental iron for 42 days can significantly increase serum BDNF levels and ferritin levels, which may suggest the ability to enhance cognitive function (memory & learning) and tolerance to iron supplementation.

Exercise Performance Study: Body Composition, Strength and Power

An 8-week double-blind, randomized, placebo-controlled study to evaluate the effect of Testofen® on muscle strength, aerobic endurance and body composition in 138 healthy exercising males.

Muscle strength (1RM leg and bench press) and muscular endurance (80% of 1RM bench and leg press until fatigue) were measured.

Body composition and functional threshold power (FTP) were also measured.

Three groups: (i) 600mg Testofen®; (ii) 300mg Testofen®; (iii) Placebo

Study Results:

Dose-dependent improvement in lower body strength across all three groups.

600mg Testofen® significantly:

Testofen® at a 600 mg/day dose in conjunction with an effective exercise regime has superior positive effects in leg strength, aerobic capacity and body composition compared with placebo and a 300 mg/day dose. Testofen® may be an effective ergogenic aid for those wanting to rapidly improve their exercise performance capabilities and body composition above and beyond that of only exercise training.
