Carotenoids are hydrophobic pigments produced exclusively by plants, fungi, and specific microbes. Microalgae are well suited for the production of valuable carotenoids due to their rapid growth, effi...
Lutein is a high-value tetraterpenoid carotenoid that is widely used in feed, cosmetics, food, and drugs. Microbial synthesis of lutein is an important method for green and sustainable production, ser...
Newborns' eyes and brains are prone to oxidative stress. Lutein has antioxidant properties and is the main component of macular pigment essential for protecting the retina, but has low bioavailability...
Abnormal interaction between granulosa cells and oocytes causes disordered development of ovarian follicles. However, the interactions between oocytes and cumulus granulosa cells (CGs), oocytes and mu...
Lutein (LT) is a natural carotenoid and is widely used for its vision protection and antioxidant activity. However, the long-chain polyene structure makes lutein sensitive to light and oxygen and pose...
Vitamin D status has been associated with sex steroid production. The question is whether vitamin D supplementation has an impact on sex steroid production in infertile men with vitamin D insufficienc...
A single-center, double-blinded, randomized clinical trial. Differences in sex steroids and reproductive hormones were predefined secondary outcomes, vitamin D status at baseline was a predefined subg...
A total of 307 infertile men were included and randomized 1:1 to active or placebo treatment for 150 days. Men in the active group initially received an oral bolus of 300,000 IU cholecalciferol, follo...
After intervention, no differences were found in serum concentrations of sex steroids, luteinizing hormone, testosterone/luteinizing hormone ratio or SHBG between the vitamin D and placebo group. Howe...
Vitamin D + calcium supplementation did not alter sex steroid production in infertile men. However, vitamin D insufficient men treated with vitamin D supplementation had a significantly higher testost...
Neurodegenerative diseases are defined by specific protein accumulation and anatomic vulnerability leading to neuronal loss. Some studies have shown that lutein may have an effect on neurodegenerative...
A systematic search was carried out in the available databases. We used all MeSH terms and relevant keywords. Studies that reported relationship between lutein and any neurodegenerative disease were i...
We found 278 studies. After removing duplicates, screening by titles and abstracts and excluding irrelevant papers, 17 articles were included in this study. Fourteen studies investigated Alzheimer's d...
4/17 studies confirm that lutein can improve cognitive function. 8/17 studies demonstrate a reduction in the progression of AD, and 2/17 studies indicate an improvement in lipid profiles. However, som...
