Udo's Choice study on athletic performance

The study was carried out to determine how essential fatty acids (EFAs) affect athletic performance and general well being, and what role EFAs play in decreasing cardiovascular risk factors.

The source of EFAs used in the study was Udo's Choice Ultimate OIl Blend

The study was carried out by Oscar Umahro Cadogan, a sports and fitness expert from Denmark, and nutritional consultant to some of Denmark's top national athletes.  Mr. Cadogan is an external lecturer for the Danish Institute of Optimal Nutrition, the Danish School of Heilpraktik, and the Danish Open University. He is also a member of a group of experts commissioned by the Danish Dietetic Association to establish better eating habits for future generations.



The Goals of the study

1. The Effects of Essential Fatty Acids on:

  • Athletic Performance
  • General Well Being
  • Risk Factors For Cardiovascular Disease

2. Can Aggressive Dosing with Udo's Oil Blend Improve Athletic Performance And General Well Being?

3. Can Aggressive Dosing with Udo's Oil Blend Change Cardiovascular Risk Factors?

The 6l participants in the study were chosen from the following disciplines:

Basketball 13
Triathlon 3
Duathlon 1
Medium-distance running 9
Capoeira 5
Cycling 9
Boxing 6
Kickboxing 5
Weight-resistance and fitness training 5
Physically active diabetics 5

There were 13 females and 48 males ranging in age from 16 to 62 years with an average age of 31.

Each particiapant ingested large amounts of Udo's Oil Blend for approximately 8 weeks. No concurrent changes were made to either their diet or their training. The initial dosage was 0.3 grams of Udo's Oil Blend per kg of body weight daily for the first 7 days; 0.45 grams per kg of body weight from day 8 to day 14; and 0.6 grams per kg of body weight onward.


Blood tests measuring various cardiovascular risk factors were analyzed at the Clinical Biochemical Ward, Aarhus State Hospital, Denmark.

The participants' subjective responses were obtained in relation to:

  • athletic performance,
  • general well-being,
  • and side effects

These were compiled through questionnaires and interviews. Participants were asked to fill out questionnaires after 3 weeks, 6 weeks, and upon cessation of the trial. Interviews were carried out after 4 weeks of supplementation and upon cessation of the trial. Valid information on subjective responses was obtained from 47 of the 6l persons who initially enrolled in the trial.


Thirty-five out of the 47 participants, who gave reliable feedback to the questionnaires and interviews, experienced subjective improvement in athletic performance; 31 participants experienced improvement in general well being and 21 nioted mild side effects.

Athletic Performance

The greatest effects seemed to be on stamina and endurance, as well as a decrease in recovery time after training and competitions..

One runner went from running a total of approximately 90 km a week, to running a total of l47 km a week, without reaching the point of overstraining. Previous attempts to increase the total km run per week to more than 90 km were unsuccessful because he would overtrain and thus wear himself down.

A cyclist increased his 60-80 km a day to a total of l00-l20 km a day without reaching the point of overtraining. He also experienced a significant improvement in general well being, including healing of permanent sitting sores and anal fissures.

One amateur boxer increased his stamina and endurance and went from being able to do 1.5-hour training sessions before getting exhausted, to doing 2.5-hour training sessions before reaching exhaustion.

At gatherings with the Danish National Triathlon Team, one triathlete was able to train intensively all day long seven days in a row at Club La Santa Sport in Lanzarote without exhausting himself. Before entering the trial, he had attended training camps at Club La Santa Sport with the Danish national team several times a year for several years in a row. At that time, he was only able to train intensively all day long for 3-4 days in a row before exhausting himself and hence being forced to train at a much lower intensity for the remainder of the week. He went to Club La Santa Sport with the Danish national team twice while participating in the trial and experienced these improvements in stamina and endurance as well as the decrease in recovery time. This enabled him to train intensively all day for all 7 days both times, without reaching the point of exhaustion.

Research shows that essential fatty acids (EFAs) and some of the eicosanoids produced from several of these EFAs can improve various biochemical and physiological reactions in the body. These reactions play key roles in enhancing athletic performance. This includes an increase in blood flow and oxygenation of tissues, as well as an increase in the ability to absorb and utilize oxygen (VO2 max) . These effects of EFAs on human physiology and biochemistry could explain why so many of the participants in the trial experienced improvement in stamina and endurance, as well as a decrease in recovery time after physical exertion. The anti-inflammatory effects of EFAs likely played a role in the decrease in recovery time as well. Mild inflammation occurs in various tissues - muscles, joints, connective tissue, etc. - after physical exercise when the immune system becomes engaged in breaking down dead and damaged cells. If this post-exercise inflammatory state becomes too pronounced, healthy cells can also get damaged. Therefore the recovery time increases because healthy tissue is also being destroyed by the immune system. Consequently, an over-pronounced post-training inflammatory state can occur due to the following:

  • a lack of EFAs
  • an over-production of pro-inflammatory eicosanoids from arachidonic acid
  • a lack of antioxidants


Improvements in General Well Being.

A good number of participants experienced improved sleep. They either slept more soundly or had fewer problems falling asleep.

Improvement in No.
  • sleep
  • concentration
  • energy levels
  • inflammation
  • mood
  • weight
  • skin

Side effects

These were mostly transient cases of nausea or digestive problems when initially increasing the dosage of the oil blend to 0.6 grams per kg of body weight daily. In a few cases the dosage of the oil blend had to be reduced to 0.45 grams or 0.3 grams per kg of body weight daily to curtail the side effects.

Cardiovascular risk factors were measured for forty-one (41) out of the total 6l participants in the trial.

the cardiovascular risk factors listed below were measured through blood samples taken before and after 8 weeks of supplementation with the oil blend.

  • fasting glucose,
  • hemoglobin A1c (HbAc1),
  • lipoprotein a - Lp (a),
  • fibrinogen,
  • triglycerides,
  • total cholesterol,
  • HDL-cholesterol,
  • and LDL-cholesterol

The parameters listed below were measured in another sub-group of 9 participants (5 females and 4 males) through blood samples taken before and after 8 weeks of supplementation.

  • free testosterone,
  • TSH,
  • TT4,
  • free TT3,
  • and TT3 capacity.
