Evaluation of the Pharmacokinetics, Safety and Effects of NutriterraTM in Healthy Adults

19 décembre 2019 mis à jour par: Nuseed Americas Inc.

A Randomized, Double-Blind, Placebo-Controlled Dose Ranging Study to Evaluate the Pharmacokinetics, Safety and Effects of NutriterraTM in Healthy Adult Subjects

The blood lipid profile plays a role in health and disease states and is affected by many genetic and lifestyle factors. On the more extreme side, hyperlipidemia (a condition characterized by hypertriglyceridemia, hypercholesteremia, or both) is a risk factor for coronary heart disease (CHD) 1. CHD is the most common form of cardiovascular disease (CVD); it is characterized by arterial obstructions or blockages, and is a leading cause of heart attacks and strokes 2. Specifically, blood lipids including triglycerides (TG), total cholesterol (TC), low density lipoprotein-cholesterol (LDL-C), and the ratio of TC: high density lipoprotein (HDL) cholesterol, are key modifiable risk factors for CHD. Hyperlipidemia is thought to be caused or promoted by sedentary lifestyle, obesity, or uncontrolled type 2 diabetes 2. Therefore, lifestyle factors, like the modification of dietary lipids to maintain a healthy blood lipid profile are warranted.

There are many beneficial effects of omega-3 fatty acids in terms of cardiovascular disease and the nervous system in general, as well as emerging research on DHA supplementation in acute brain and spinal cord injury. Demand for dietary omega-3's, either through increased fish consumption or through DHA supplementation, is expected to increase, particularly as the baby boomer population adds to the ranks of senior citizens concerned about and/or susceptible to health issues such as dementia and Alzheimer's Disease. Availability of EPA and DHA in circulation is an important parameter in understanding biologic properties of fatty acids.

The purpose of this study is to evaluate the pharmacokinetic characteristics of ascending doses of NutriterraTM, as measured by plasma levels of total EPA, DHA, DPA and ALA under fed conditions. In addition, after a two-week (minimum) washout period, subjects will take product for 16 weeks to evaluate effects on cardiovascular markers as a measure of efficacy.

  • Consume less than 200 mg omega-3 per day based on validated Questionnaire
  • Agrees to stop taking any vitamins, minerals, or any fatty acid containing dietary/herbal supplements that could potentially interfere with the study endpoints and will be washed out for two weeks prior to study product administration and throughout the study.
  • Willing to maintain a stable diet and level of activity throughout the trial.
  • Willing to keep a daily journal describing impact of dosage and tolerability.
  • Able to comply with all protocol activities.
  • Willing and able to provide informed written consent.

Exclusion Criteria:

  • Consumption of fish within two weeks prior to the first investigational product administration and for the duration of the study.
  • Used canola oil, fish oil, other omega-3 fatty acids (EPA and/or DHA) containing supplements within one (1) month of baseline (Visit 2) or any time during the study, other than the product being evaluated in this study.
  • Have a known sensitivity or allergy to canola or any other ingredients in the test products.
  • Individuals taking prescription or non-prescription health products that may affect the study endpoint (e.g. corticosteroids, prescription anti-inflammatory drugs, blood lipid-lowering drugs (e.g. statins, fibrates, bile acid exchanger resin, phytosterols, niacin or its analogues, carnitine, etc.) in the previous 6 months.
  • Individuals taking any supplements with phytosterols, polyglucosamines (Chitosan) or other lipid-binding ingredients in the previous 3 months.
  • Unstable use (i.e. initiation or change in dose) of antihypertensive medications or thyroid hormone replacement medications within 3 months prior to visit 1.
  • Use of any weight-loss programs or weight-loss medications (prescription or over-the counter) including, but not limited to, lipase inhibitors, within 6 months prior to visit 1 and throughout the study.
  • Pregnancy or lactation, or participant unwilling to take appropriate contraceptives for the duration of the study.
