Fenugreek seed powder and capsules containing fenugreek

Answer:

Fenugreek is an herb that belongs to the legume family. It is used as a spice and for cooking in some parts of the world. The seeds, which are used medicinally, contain about 23% protein, 6% fat, and 25% fiber (FoodData Central, 7-24-23). The fiber content is thought to contribute to certain purported health benefits of fenugreek (Srinivasan, Food Rev Int 2006). Fenugreek also contains furostanolic saponins, compounds that may affect the production of sex hormones such as estradiol and testosterone, and trigonelline, a niacin-related compound.

Although supplements containing fenugreek seed extract are often standardized to higher concentrations of constituents, such as saponins, it is unclear if such products have greater clinical benefit, if any, compared to products containing only fenugreek seed.

There is a risk of low potassium (hypokalemia) with fenugreek. My potassium levels went down slowly but surely when taking a fairly large amount (5-10grams/day). Fenugreek helped my blood sugar, but I had to stop due to my potassium level.

I tried fenugreek to help with lactation and found no benefit, but it did aggravate my colitis, which I hadn't suffered from for 15 years. Cleared up after I stopped taking fenugreek. I'm not a fan, although my lactation consultant was extremely convinced that it works, but it definitely is not something I'd ever take again.

Are whole seeds digestible or do they need to be crushed or partially processed to absorb nutrients?

The processing of fenugreek seed appears to increase the content of certain macronutrients, vitamins and minerals while decreasing the content of others, as discussed in the following article: https://ift.onlinelibrary.wiley.com/doi/10.1111/1750-3841.16970

I think it might be worth mentioning trigonilline. It would be nice to see some labs about the trigonilline content here someday.

Agreed. Trigonelline has received significant interest as an NAD+ precursor. It has a strong presence in fenugreek and coffee.

Is Fenugreek safe for postmenopausal women who have previously had estrogen positive breast cancer, 10+ years ago?

Nothing is mentioned about fenugreek taken along with Turmeric to increase absorption. Perhaps I missed your commentary.

Please see the following section of our Turmeric Supplements Review for information about the effect of fenugreek on turmeric absorption: https://www.consumerlab.com/reviews/turmeric-curcumin-supplements-spice-review/turmeric/#curqfen

Are there any studies in boosting testosterone in women? We loose it, along with the estrogens, especially with menopause. If no studies, anecdotal reports? Do you have any recommendations?

As noted in our article about supplements that boost testosterone, DHEA (dehydroepiandrosterone) has been shown to increase testosterone levels in women: https://www.consumerlab.com/answers/supplements-for-boosting-testosterone/testosterone-boosters/#dhea.
