Vitamin A5 is a fascinating “new” vitamin that acts as a vital key in your body. It helps activate something called the Retinoid X Receptor (RXR), which is like a central control panel or “master switch” for many important functions. This crucial vitamin comes from certain foods, especially leafy green vegetables. Research suggests that many people in Western countries aren’t consuming enough of these foods, leading to a potential Vitamin A5 deficiency. This lack could be a contributing factor to the rising rates of poor mental health and neurological issues. By making sure you get enough Vitamin A5 through your […]
A randomized, double-blind, placebo-controlled trial investigated the sleep-promoting effects of Heukharang lettuce (Lactuca sativa L.) extract in Korean adults aged 30-65 with poor sleep quality (Pittsburgh Sleep Quality Index (PSQI) score 5). Over four weeks, participants received two capsules daily of either the test extract or a placebo. The study found that the test group showed a greater improvement in global PSQI scores compared to the placebo group (6.48 ± 0.63 vs. 7.41 ± 0.57, p=0.0462). Objective measurements from actigraphy revealed significant improvements in total sleep time (TST) (421.68 ± 13.29 min vs. 386.57 ± 12.27 min, p=0.0023) and sleep […]

Fatty liver-associated indicators such as the Fatty Liver Index (FLI) […]
This video explores the significant potential of bergamot, particularly its Bergamot Polyphenolic Fraction (BPF), in managing cholesterol levels, based on a review in Nutrients. Bergamot primarily lowers cholesterol by inhibiting HMG-CoA reductase, the same enzyme targeted by statins, with compounds like brutieridin and melitidin playing a key role ; in vitro studies have shown up to a 30-40% reduction in cholesterol synthesis in liver cells. Clinical trials demonstrate notable LDL-C reductions, for example, 500 mg/day of BPF decreased LDL-C by 24.1% in 30 days , while 1000 mg/day lowered LDL-C by 40.8%. Doses up to 1300 mg/day have resulted in […]
A recent sub-study of the large-scale VITamin D and OmegA-3 TriaL (VITAL), published in The American Journal of Clinical Nutrition, has revealed significant findings regarding vitamin D and cellular aging. Researchers analyzed leukocyte telomere length (LTL) in 1,054 participants over four years. The results showed that daily supplementation with 2,000 IU of vitamin D3 significantly reduced telomere shortening compared to a placebo. Specifically, vitamin D3 supplementation decreased LTL attrition by 0.14 kilobase pairs over the four years (p=0.039), an effect described as equivalent to preventing nearly three years of biological aging. This is the first large-scale, long-term randomized trial to […]
A recent randomized, double-blind, crossover trial published in Nutrients investigated the effects of short-term beetroot juice (BJ) supplementation on resistance-trained males. Eleven healthy men (average age 21.3±1.9 years) consumed either beetroot juice, providing 450 mg of nitrate per day, or a nitrate-free placebo. The study found that BJ supplementation significantly enhanced high-intensity resistance performance. Specifically, participants completed more repetitions at 80% of their one-repetition maximum (1RM) in both bench press and back squat exercises when taking beetroot juice compared to the placebo. Peak movement velocity also improved across all tested intensities (60-80% 1RM) with BJ supplementation. Furthermore, beetroot juice led […]
A recent study in mice explored how a combination of two supplements, lactoferrin and creatine, might help with age-related muscle loss, a condition called sarcopenia. Scientists induced sarcopenia in mice, causing their muscle mass and function to decline. For 8 weeks, these mice were given lactoferrin, creatine, or a mixture of both. The results were promising: the group of mice receiving both lactoferrin and creatine showed the most significant improvements. For example, the lean body content in the sarcopenia model group dropped to around 47-48%, while the group receiving the combination treatment saw their lean body content increase to about […]
A recent PRISMA-guided systematic review published in Nutrients synthesized findings from randomized controlled trials (RCTs) to assess the impact of monk fruit extract (MFE) on metabolic health, lipid profiles, inflammation, and regulatory considerations.
