Best Of Fenugreek Research

November 12, 2010 Written by JP       [Font too small?]

Very few health conditions are brought about by genetic factors alone. Some people may be prone to elevated cholesterol, high blood pressure, obesity or type 2 diabetes. But it’s extremely uncommon that such health concerns are solely influenced by a familial predisposition. More often than not these conditions are influenced by diet and lifestyle choices that are less than optimal. A pertinent analogy for this might be that genes are like a field. If you eat well, exercise regularly, practice stress reduction and supplement wisely, you will, in effect, encourage lush green plant life to grow. However, if you don’t take proper care of yourself, the field will become dry and lifeless. When ash or a spark comes drifting your way, which type of a field would you rather be?

On many occasions I’ve emphasized that supplements are not a replacement for healthy lifestyle choices. But the fact of the matter is that many people fall short of their dietary and exercise goals. Another reality is that some people have stronger genetic hurdles to overcome. In both of these instances, supplements can often play a more prominent role in managing wellness naturally.

According to the National Center for Complementary and Alternative Medicine, fenugreek (Trigonella foenum-graecum) was first mentioned in “an Egyptian papyrus” dating back to 1500 B.C. This culinary herb has traditionally been used to support milk production in pregnant women, healthy digestion and even to reduce inflammatory conditions relating to the skin. However, in recent years scientists have focused on fenugreek’s ability to counter several maladies that are extremely common in the 21st century. (1)

Two recent studies on fenugreek indicate that it may play a valuable role in the arena of hunger management. The first trial was published in the November 2009 issue of Phytotherapy Research. It involved 18 “healthy obese subjects”. Each of the participants ate three breakfasts that were supplemented with varying levels of fenugreek fiber – 0 grams (used as a “control” or comparison), 4 grams or 8 grams. Dietary records were kept that detailed the food consumed in meals and snacks following the experimental breakfasts. Several significant findings were noted:

  • The meals containing 8 grams of fenugreek fiber supported a greater feeling of fullness and satiety.
  • This reduced level of hunger decreased subsequent food consumption on the days when the 8 gram dosage was administered.
  • The caloric intake in the groups receiving 4 and 8 grams of fenugreek also dropped during lunch time meals. (2)

A study from the October 2009 edition of the European Journal of Clinical Pharmacology explains that fenugreek seeds have been shown to reduce “feeding behavior in animals, but strong clinical data (in humans) are lacking”. In order to remedy this information gap, a group of 12 healthy male volunteers were enrolled in a double-blind randomized placebo-controlled study. On three separate occasions, the men were given either a placebo, 588 mg of a fenugreek seed extract or 1,176 mg of the extract. There was a “washout period” of 14 days between each test in order to rule out any competing influence. The results of this experiment indicate that the higher dosage of fenugreek significantly reduced fat and total caloric intake while having no ill effect on nutrient levels. (3)

If a reduction in appetite was all that fenugreek could accomplish, I probably wouldn’t devote an entire column to it. But it also appears to provide some valuable benefits with regard to blood sugar disorders and cardiovascular health. Here are some of the key findings that I discovered while sifting through the most recent scientific data:

  • A new Iranian study examined the effects of 10 grams of “powdered fenugreek seeds” in a group of 24 type 2 diabetics. The fenugreek powder was either “soaked in hot water” or mixed into yogurt and fed to the diabetics over the course of 8 weeks. The subjects who were in the “hot water” group demonstrated statistically significant reductions in fasting blood sugar, VLDL (“bad”) cholesterol and triglyceride levels. But those receiving the fenugreek-enhanced yogurt showed no such benefits. This research suggests that certain water soluble fractions of fenugreek may be responsible for its therapeutic activity. (4)
  • Several animal studies provide a basis for the lipid-modifying effects of fenugreek exhibited in the previous study. An Indian trial from the October 2009 issue of the journal Obesity, discovered that fenugreek could assist the body in processing LDL cholesterol and decrease fat accumulation in mice. These results may help explain why other recent animal studies demonstrate fenugreek’s ability to reduce plaque formation in the arteries of rabbits and even reduce the likelihood of cholesterol-based gallstones in mice receiving a high cholesterol diet.

Perhaps the biggest question about fenugreek that’s currently being examined is how and why it works as well as it does. As I write this, there are food scientists fast at work trying to find a way to incorporate fenugreek into our modern food supply. An October 2009 study in the Journal of Medicinal Food tested the use of a proprietary fenugreek flour which was added to a commercial bread mix. The experimental bread contained 5% fenugreek flour. Testing on 8 “diet-controlled diabetic subjects” found that the fenugreek bread helped to manage blood sugar and insulin more successfully than a 100% whole wheat bread. Another important finding was that the taste of the fenugreek bread was “indistinguishable from the whole wheat bread control”. (8)

A substance by the name of 4-hydroxyisoleucine is believed to be at least partially responsible for the blood sugar balancing effect of fenugreek. This “atypical branched-chain amino acid” has been shown to reduce insulin resistance in the liver and muscles, and stimulate insulin secretion by the pancreas. The weight loss demonstrated in certain animal studies is postulated as being one more way in which fenugreek can cause a decline in blood sugar and plasma insulin concentrations. This evidence recently prompted a group of Canadian researchers to remark that, “4-hydroxyisoleucine, a simple, plant-derived amino acid, may represent an attractive new candidate for the treatment of type 2 diabetes, obesity and dyslipidemia, all key components of metabolic syndrome”. Other scientists report that even long term exposure (in animal models) to 4-hydroxyisoleucine does not damage the liver and appears to improve certain cardiovascular risk factors such as HDL (“good”) cholesterol levels. (9,10,11)

The truth of the matter is that researchers are often left wondering exactly how natural “medicines” work. Herbal extracts are frequently comprised of hundreds, if not thousands, of naturally-occurring chemicals. Most prescription medications are synthesized in a laboratory and contain only one, isolated chemical. This is partially why it’s not yet clear whether the healing properties of fenugreek are due solely to 4-hydroxyisoleucine, water soluble phytochemicals or possibly even a viscous form of fiber known as galactomannan. The overall potential of fenugreek is also not entirely clear. Preliminary research indicates that it may benefit aspects of health that extend far beyond blood sugar, cholesterol and weight. In recent years, scientific trials point to fenugreek as a possible analgesic (pain reliever), a liver protector and a memory enhancer. There is even a study underway to verify its time tested ability to safely support lactation in women who have difficulty producing adequate breast milk. Fenugreek has indeed come full circle. But now, that circle is expanding. We’re learning more about this valuable spice each day and the information is becoming available just in the nick of time. (12,13,14,15,16,17)

Update: November 2010 - The October 2010 edition of the Journal of the International Society of Sports Nutrition reveals yet another side of fenugreek – as an ergogenic aid. A group of forty-nine “resistance trained men were matched according to body weight and randomly assigned (in a double blind trial) capsules containing 500 mg of a placebo or fenugreek”. Over an 8 week period, the participants engaged in an identical 4-day a week resistance training program. Measurements pertaining to body composition, exercise performance and strength were taken at baseline, after 4 weeks and at the end of trial. Several noteworthy differences were detected between the fenugreek and placebo groups: a) the fenugreek subjects lost more body fat: -2.3% vs. -1.4%; and b) significantly greater gains in bench- and leg-press exercises were recorded in those receiving the fenugreek capsules. A variety of blood tests were conducted on both groups as well. No alterations in clinical safety data (complete blood count, kidney and liver function, lipids, etc.) were detected in any of the study volunteers. The findings of this pilot trial indicate that this proprietary fenugreek extract (Torabolic) has “a significant impact on both upper- and lower-body strength and body composition”. Longer term studies are now needed to expand upon and verify these preliminary results. (18)

    Liverock,

    I’ve seen such products on the market. I just haven’t found any solid data to back them up. The closest thing I’ve found re: fenugreek/hair is that: a) it may deter lice and b) a sponsored study by a supplement manufacture claims it supports thicker hair.

    *If* it really works, it would almost certainly be a best seller … more hair and strength gains?! Sounds like a blockbuster to me! ;)

    Fenugreek seeds or leaves have great medicinal value. We indians use it in many way. Make a vegetable from it, or put it in curry and many more recipies. It is of great value.

    Aging Male. 2016 Jan 20:1-9.

    Testofen, a specialised Trigonella foenum-graecum seed extract reduces age-related symptoms of androgen decrease, increases testosterone levels and improves sexual function in healthy aging males in a double-blind randomised clinical study.

    This study examined the effect of Testofen, a specialised Trigonella foenum-graecum seed extract on the symptoms of possible androgen deficiency, sexual function and serum androgen concentrations in healthy aging males. This was a double-blind, randomised, placebo-controlled trial involving 120 healthy men aged between 43 and 70 years of age. The active treatment was standardised Trigonella foenum-graecum seed extract at a dose of 600 mg/day for 12 weeks. The primary outcome measure was the change in the Aging Male Symptom questionnaire (AMS), a measure of possible androgen deficiency symptoms; secondary outcome measures were sexual function and serum testosterone. There was a significant decrease in AMS score over time and between the active and placebo groups. Sexual function improved, including number of morning erections and frequency of sexual activity. Both total serum testosterone and free testosterone increased compared to placebo after 12 weeks of active treatment. Trigonella foenum-graecum seed extract is a safe and effective treatment for reducing symptoms of possible androgen deficiency, improves sexual function and increases serum testosterone in healthy middle-aged and older men.

    Endocr Metab Immune Disord Drug Targets. 2019 Feb 6.

    A randomized controlled trial of a herbal compound for improving metabolic parameters in diabetic patients with uncontrolled dyslipidemia.

    OBJECTIVE: The aim of this randomized controlled trial was to investigate the effects of a polyherbal compound consisting of Aloe vera, black seed, fenugreek, garlic, milk thistle, and psyllium on diabetic patients with uncontrolled dyslipidemia.

    METHOD: Fifty patients with type 2 diabetes who had dyslipidemia in spite of statin therapy were randomly allocated to two groups: control group (n = 25) receiving a conventional therapy with hypolipidemic and hypoglycemic drugs and intervention group (n = 25) receiving both the conventional therapy and the herbal compound (one sachet twice daily) for 12 weeks. Each sachet contained 300 mg of Aloe vera leaf gel, 1.8 g of black seed, 300 mg of garlic, 2.5 g of fenugreek seed, 1 g of psyllium seed, and 500 mg of milk thistle seed.

    RESULTS: The levels of serum triglyceride, total cholesterol, low-density lipoprotein, and HbA1c showed a significant in-group improvement in the intervention group. However, effects of the herbal compound on fasting blood glucose remained insignificant. The compound had no unwanted effect on the kidney function parameters (urea, creatinine) and serum liver enzymes (alanine aminotransferase and aspartate transaminase).

    CONCLUSION: The tested herbal compound, as an add-on to statin therapy, was effective in lowering the serum lipids in diabetic patients with uncontrolled dyslipidemia.
