“There is no high quality evidence to support the effectiveness of any dietary supplement for dysmenorrhoea, and evidence of safety is lacking.”

Key Findings:

Supplements versus other supplementsThere was no evidence of a difference in effectiveness between ginger and zinc sulphate (MD 0.02 points, 95% CI -0.58 to 0.62; one RCT, 101 women).
Vitamin B1 may be more effective than fish oil (MD -1.59 points, 95% CI -2.25 to -0.93; one RCT, 120 women).
There is no high quality evidence to support the effectiveness of any dietary supplement for dysmenorrhoea, and evidence of safety is lacking.
However for several supplements there was some low quality evidence of effectiveness and more research is justified.

“The evidence presented in the current systematic review indicates that flour-derived foods intake is related to improve cardiometabolic risk factors parameters.”

Key Findings:

Chia flour, green banana flour, soy flour, and fenugreek powder showed improvements in blood pressure measurements.
Brazil nut flour and chia flour reduced total cholesterol.
Chia flour also increased HDL cholesterol levels.

“Given the wider availability and lower cost of fenugreek, rigorous double-blinded randomized controlled trials should be conducted with fenugreek to understand its true potential as a diabetes control herbal agent.”

Key Findings:

The mean difference with 95% confidence intervals (CI) was calculated to represent the analysis.
The results showed a reduction in fasting blood glucose levels (MD: 3.70, 95% CI of -27.02, 19.62; p = 0.76), postprandial blood glucose (MD: -10.61, 95% CI of -68.48, 47.26; p = 0.72), and HbA1c (MD: -0.88, 95% CI -1.49, -0.27; p = 0.00) with fenugreek consumption.
Fourteen trials, consisting of 894 participants, were included in the meta-analysis.
While this review and included trials that found beneficial effects of fenugreek consumption on glycemic control, the quality and heterogeneity of studies remain a concern.

Kumar S et al. • Diabetes & metabolic syndrome (2023)

“Several herbs could be considered as a valuable adjuvant therapy regarding glycemic control of type 2 diabetes patients.”

Key Findings:

Apple cider vinegar (ACV) (standardized mean difference (SMD) = -28.99), cinnamon (-9.73), curcumin (-13.15), and fenugreek (-19.64) significantly reduced fasting blood glucose (FBG) compared with placebo (all p < 0.05).
Notably, only ACV (SMD = -2.10) and fenugreek seeds (0.84) were found significantly effective in reducing HbA1C.
Several herbs could be considered as a valuable adjuvant therapy regarding glycemic control of type 2 diabetes patients.
Health professionals should be encouraged to incorporate these herbs for the management of type 2 diabetes as part of their standard care.

“Further high-quality studies should be conducted to establish the clinical efficacy of herbal medicines.”

Key Findings:

The mean difference (MD) and the standardized MD (SMD) were adopted, and subgroup analyses were performed according to patient's clinical condition.
Saffron supplementation reduced FBG (MD: -9.06 mg/dl; 95%CI: -16.25 to -1.86; I2 = 40%; p = 0.12) and HbA1c (MD: -0.19%; 95%CI: -0.23 to -0.14; I2 = 0%; p > 0.99).
Our results show that using saffron and fenugreek can reduce FBG, PPBG, and HbA1c; however, there are some shortcomings that require attention for these results.
Further high-quality studies should be conducted to establish the clinical efficacy of herbal medicines.
