Once-Daily Oral Dose of BeneFlax to Healthy Older Adults

The investigators are investigating whether the flax lignan, secoisolariciresinol diglucoside, decreases oxidative stress and inflammation. The flax seed lignan is believed to be broken down in the body to produce the health benefits of flax. Flax lignan is separated from the whole flax seed as this compound is believed to have health effects. Decreasing oxidative stress and inflammation should improve a number of the problems associated with aging. This intervention consists of 600 milligrams of the flax lignan SDG daily or an equivalent amount of whey protein.

The investigators are comparing lignan to a placebo (whey powder) to examine whether a dietary intervention (i.e. flax seed containing lignan) might decrease oxidative stress and inflammation.

Inclusion criteria

  • Male or female adult 60 to 80 years residing in Saskatoon.
  • Able to comply with study protocol.
  • Able to follow simple instructions.

Exclusion criteria

  • Age below 60 or above 80 years at initiation of the study.
  • Individuals living in long term care homes.
  • Individuals at risk of hypotension or with symptomatic hypotension.
  • Fasting hypoglycemia.
  • Unstable diabetes, or diabetics taking insulin (note: eligible diabetic participants will undergo additional testing during the study).
  • Current cancer or diagnosed with cancer in the past 2 years.
  • Women with an immediate family history or personal history of breast cancer or ovarian cancer.
  • Significant liver or other gastrointestinal disorder including inflammatory bowel disease. (While constipation is the most common gastrointestinal problem in the elderly, it would not be a contraindication)

Treatment and study plan

secoisolariciresinol diglucoside, vitamin D

Dietary Supplement

SDG supplementation as a packet of 1.6g/day of BeneFlax containing 600 mg SDG for 24 weeks Vitamin D Natural Product Number (NPN) 80003663 WN Pharmaceuticals Natural Factors Whey Factors

Other names: BeneFlax Flax Lignan Extract Archer Daniels Midland,#080001.

Primary outcomes

  1. Safety of consumption of 600 mg/day of the flax lignan secoisolariciresinol diglucoside (SDG) in older adults (60-80 y)

    Time frame: 24 weeks

    Adverse event occurrences will be compared descriptively between the SDG and placebo groups. Safety will be assessed at 0, 8, 16 and 24 weeks; as part of the blood collection (urea, creatinine, total bilirubin, platelets, hematocrit, haemoglobin, mean corpuscular haemoglobin, mean corpuscular volume, white blood cell count, total protein including albumin and prealbumin, total calcium, electrolytes, glucose, liver enzymes (Aspartate transaminase (AST), Alanine Aminotransferase (ALT), Alkaline phosphatase (ALP), total protein, albumin, lipids, HbA1c (for diabetic participants). Blood pressure, pulse and respiratory rate will also be monitored at these time points.

Secondary outcomes

  1. Effect of SDG on blood lipids

    Time frame: 24 weeks

    SDG and placebo groups will be compared at 0, 8, 16 and 24 weeks for changes in nonfasting levels of cholesterol, LDL, HDL, and triglycerides.

  2. Effect of SDG on inflammation

    Time frame: 24 weeks

    SDG and placebo groups will be compared at 0, 8, 16 and 24 weeks for changes in pro-inflammatory markers (Interleukin-6 (IL-6), IL-1α, IL-1β, 8-isoprostane, Tumor necrosis factor-α (TNF-α), C-reactive protein).

  3. Effect of SDG on quality of life

    Time frame: 24 weeks

    SDG and placebo groups will be compared at 0, 8, 16 and 24 weeks for changes in cognitive function, pain, and physical function.

  4. Effect of SDG supplement on blood levels of flax lignan metabolites

    Time frame: 24 weeks

    SDG and placebo groups will be compared at 0, 8, 16 and 24 weeks for changes in cognitive function, pain, and physical function.

  5. Effect of SDG supplement on fecal levels of flax lignan metabolites

    Time frame: 24 weeks

    To further understand the pharmacology of SDG, we will analyze fecal levels of the flax cyclolinopeptides. Levels will be determined 0 and 24 weeks.
