This meta-analysis was performed with 17 randomized clinical trials and evaluated the effects of omega-3 supplementation among 3363 patients in the management of dry eye disease.

omega-3 supplementation

Compared with placebo, omega-3 fatty acid supplementation decreased dry eye symptoms (p < 0.001) and corneal fluorescein staining (p = 0.032), whereas it increased the breakup time (p < 0.001) and Schirmer test values (used to test the amount of tears) (p < 0.001). No evidence of publication bias was observed, and sensitivity analyses indicated the robustness of results obtained. Meta-regression analysis showed a higher improvement of dry eye symptoms and breakup time in studies conducted in India.

 

In conclusion, this meta-analysis provides evidence that omega-3 fatty acid supplementation significantly improves dry eye symptoms and signs in patients with dry eye disease.

Vitamin C is a strong antioxidant. The authors of this study wished to determine whether this antioxidant capacity can help to prevent exercise-induced muscle damage. 19 healthy women have been recruited for this randomized, double-blinded and placebo-controlled trial which used a crossover design including a 1-week washout period.

They performed 30 min moderate intensity cycling after ingesting 1 g vitamin C or placebo.

Vitamin C

Vitamin C prevented the increases in plasma albumin and total protein levels, and the reduction in glucose observed after placebo (p = 0.001). Superoxide dismutase was increased after placebo but not after vitamin C (p = 0.002), whereas malondialdehyde decreased only after the vitamin C supplementation (p < 0.05). Slight muscle damage have been noted in both groups after exercise, without differences between groups.

 

Therefore, vitamin C possesses antioxidant effects during exercise, but does not prevent muscle damage.

The effects of alpha lipoid acid (ALA) on plasma lipids remains unclear due to contradictory results obtained in clinical trials. To clarify the effects of ALA, this meta-analysis includes 12 randomized and controlled trials assessing the effects of ALA on lipid profile.

 

alpha lipoic acid

 

Results show that ALA reduces total cholesterol level in comparison to controls (Weight mean difference = -10.18 mg/dL, 95% CI: -16.16, -4.20 mg/dL, p = 0.001). A significant reduction in LDL-cholesterol has also been measured (WMD = -9.22 mg/dL, 95% CI: -18.28, -0.16 mg/dL, p = 0.001). However, no change in HDL-cholesterol has been measured. Regarding triglycerides, the analysis show no significant effect of ALA on triglycerides, except in a subgroup analysis based in health status (diabetic vs. diabetic) in which triglycerides were reduced in both populations.

 

Therefore, ALA reduce plasma lipids. However, the consequences of these changes has to be clarified, notably regarding cardiovascular diseases.

The aim of this observational study was to analyze the association between retinoid intake (total vitamin A, retinol, β-carotene, α-carotene, β-cryptoxanthin, lycopene, as wellas lutein and zeaxanthin) and self-reported gastrointestinal symptoms (daily number of bowel movements, and the presence of painful tenesmus, flatulence, and constipation) in Caucasian individuals in the remission phase of  ulcerative colitis.

To do so, 56 ulcerative colitis remission individuals were recruited and retinoid intakes were analyzed on the basis of three-day dietary records.

 

Box plots of lutein and zeaxanthin intake

Box plots of lutein and zeaxanthin intake in groups of individuals stratified by the analyzed symptoms of tenesmus, flatulence and constipation. (-) symptom not declared; (+) symptom declared.

 

Results showed that one in every seven individuals reported recurring constipation. Higher intake of lutein and zeaxanthin may lower the incidence of constipation (p = 0.013).

Authors concluded that the intake of retinoids other than lutein and zeaxanthin was not associated with the incidence of constipation or other gastrointestinal symptoms.

This randomized clinical trial aimed to evaluate the effect of isoflavone administration, either in conjunction with probiotic use or not, on the symptoms of genitourinary syndrome of menopause, and compare the effects with those of hormone therapy, in 60 postmenopausal women aged 40 to 60 years, for 16 weeks.

Probiotics improve the metabolism of isoflavones in menopausal women

Volunteers received oral isoflavone (150 mg dry extract of glycine max) alone or isoflavone plus probiotic (Lactobacillus acidophilus, Lactobacillus casei, Lactococcus lactis, Bifidobacterium bifidum, and Bifidobacterium lactis) or hormone therapy (1  mg estradiol and 0.5  mg norethisterone acetate).

 

There was a significant increase in the daidzein, glycitein, equol intermediate, and O-dimethylangolensin contents, after 16 weeks, in the isoflavone plus probiotic group. The vaginal health score increased in the isoflavone and hormone therapy groups.

 

Probiotics improved the metabolism of isoflavones after 16 weeks of treatment. However, the increase in the contents of isoflavones and their metabolites failed to yield an estrogenic effect on the urogenital tract and relieve the vulvovaginal symptoms.
