Effect of Vitamins and Dietary Supplements on Cardiovascular Health

Nutrients and Dietary Approaches in Patients with Type 2 Diabetes Mellitus and Cardiovascular Disease: A Narrative Review

Cardiovascular disease (CVD) is the most common cause of morbidity and mortality in developed countries. The prevalence of CVD is much higher in patients with type 2 diabetes mellitus (T2DM), who may benefit from lifestyle changes, which include adapted diets. In this review, we provide the role of different groups of nutrients in patients with T2DM and CVD, as well as dietary approaches that have been associated with better and worse outcomes in those patients. Many different diets and supplements have proved to be beneficial in T2DM and CVD, but further studies, guidelines, and dietary recommendations are particularly required for patients with both diseases.

3D printing of four-in-one oral polypill with multiple release profiles for personalized delivery of caffeine and vitamin B analogues

Personalized supplementation has found recent momentum with an estimated global market size of USD 1.6 billion in 2019 and an expected CAGR of 8.5% between 2020 and 2028. Alongside this rising trend, a simple, accurate, inexpensive and flexible method to produce personalized dosage forms of a wide variety of supplements would be beneficial to both the industry players and individual consumers. Here, we present a 3D printing method to fabricate a four-in-one oral polypill with multiple release profiles for personalized delivery of caffeine and vitamin B analogues. The 3D printable formulations were fabricated and optimized from existing FDA GRAS excipients based on their viscosity, shear thinning properties, recovery of paste and mechanical strength. In the polypill, vitamin B analogues and caffeine were used as the model dietary ingredients. We performed a standard 2 stage USP in vitro dissolution test of the polypill, and demonstrated that vitamin B1, B3 and B6 could be immediately released within 30 min, while caffeine could be slowly released over a period of 4 h. This demonstrated the ability dietary supplement containing different ingredients with varying release profiles, all within a single polypill. Throughout the formulation and 3D printing process, there were no detectable changes to the dietary ingredients nor any interactions with the excipients. This method serves as an intriguing complement to traditional manufacturing of oral tablets, especially when flexibility in design, dose, volume and release profiles of each dietary ingredient is required, as exemplified in personalized supplementation.
