Evaluation of a Food Supplement with Collagen Hydrolysate and Micronutrients on Skin Appearance and Beauty Effects: A Randomized, Double-Blind, PlaceboControlled Clinical Study with Healthy Subjects

Skin health, skin appearance and skin beauty are influenced by collagen composition of the dermis. Natural aging affects the structural integrity of the collagen network. Not only collagen peptides, but also micronutrients can beneficially affect skin appearance. Aim of this study was to investigate the effect of a food supplement with collagen hydrolysate and micronutrients on skin beauty. The test product was assessed for its capability to reduce wrinkles and to improve skin hydration and collagen structure.

Pharmacokinetics of Sodium and Calcium Salts of (6S)-5-Methyltetrahydrofolic Acid Compared to Folic Acid and Indirect Comparison of the Two Salts.

In a randomized, double blind cross over study, we compared the area under the curve (AUC), Cmax, and Tmax of plasma (6S)-5-Methyl-THF after intakes of (6S)-5-Methyl-THF-Na salt (Arcofolin®) and folic acid. In conclusion, a single oral dose of (6S)-5-Methyl-THF-Na caused higher AUC 0–8 h and Cmax of plasma (6S)-5-Methyl-THF compared to folic acid. The Na- and Ca- salts of (6S)-5-Methyl-THF are not likely to differ in their pharmacokinetics.

LDL-cholesterol lowering effect of hydroxytyrosol (HTEssence®): A randomized double-blind, placebo-controlled parallel study

Nutraceuticals containing hydroxytyrosol have been shown to exert a wide range of beneficial effects on the cardiovascular system like lipid modification and cholesterol reduction. The aim of this randomized doubleblind, placebo-controlled parallel study was to investigate the effects of a pure, synthetic form of hydroxytyrosol (HTEssence®) on the lipid profile in subjects with elevated LDL-cholesterol level.

Plasma Kinetics of Choline and Choline Metabolites After A Single Dose of SuperbaBoostTM Krill Oil or Choline Bitartrate in Healthy Volunteers

Choline is required for numerous biological processes, including the synthesis of neurotransmitters, and it is an important prerequisite for structural integrity and the functioning of cells. This study in healthy volunteers aimed to compare the pharmacokinetics of free choline and of selected choline metabolites between the single dose intake of phosphatidylcholine, present in SuperbaBoostTM krill oil, and choline bitartrate salt.

Artificial intelligence identified peptides modulate inflammation in healthy adults

Dietary bioactive peptides have been, among many functionalities, associated with immune modulation and thereby may improve resolution of inflammation. The goals of this research were to assess (1) whether specific peptides with immune-modulating activity consumed as part of a rice protein hydrolysate could be absorbed into blood and (2) whether they modulate inflammation markers. Artificial intelligence algorithms were applied to target, predict and unlock inflammation-modulating peptides from rice protein.

A Novel Self-Emulsifying Drug Delivery System (SEDDS) Based on VESIsorb® Formulation Technology Improving the Oral Bioavailability of Cannabidiol in Healthy Subjects

To overcome the limited oral bioavailability and the absorption variability in humans of CBD, a novel self-emulsifying drug delivery system (SEDDS) based on VESIsorb® formulation technology incorporating CBD, as Hemp-Extract, was developed (SEDDS-CBD). The study objective was to evaluate the pharmacokinetic profile of SEDDS-CBD in a randomized, double-blind, cross-over design in 16 healthy volunteers under fasted conditions.

Postprandial Effects of a Proprietary Milk Protein Hydrolysate Containing Bioactive Peptides in Prediabetic Subjects

Milk proteins have been hypothesized to protect against type 2 diabetes (T2DM) by beneficially modulating glycemic response, predominantly in the postprandial status. In the present study, the impact of a milk protein hydrolysate of native whey origin with alpha-glucosidase inhibiting properties was determined in prediabetics in a randomized, cross-over trial.

A liquid phospholipid formulation of a Curcumin extract with high concentration of phosphatidylcholine (PHOSAL® Curcumin) improves the transport of Curcuminoids across Caco-2 intestinal epithelial cells

The use of curcumin as dietary supplement to ameliorate inflammation, arthritis, stomach, skin, liver, and gallbladder problems, is hampered by the lack of oral absorption. In this study, an in vitro digestion method and Caco-2 cell-lines were used to assess the influence of the solubilisation of curcuminoids in a liquid formulation comprising a high content of phosphatidylcholine on the transport of the curcuminoids across a Caco-2 cell monolayer, compared to powdered curcuminoids.

Dietary and lifestyle predictors of folate insufficiency in non-supplemented German women

Low folate status is a risk factor for birth defects. We studied concentrations of red blood cell (RBC)- and serum folate in 198 German women in relation to information on dietary folate intake, demographic and lifestyle factors.
