Naturally occurring vitamin D is found in only a limited number of foods, mainly animal-based sources such as cod liver oil, fatty and lean fish, meat, eggs, poultry, and dairy products, while plant-based sources include mushrooms, yeast, phytoplankton, and plants containing ergosterol that can be converted into ergocalciferol (vitamin D 2 )
However, these studies are observational, not randomized trials, so we cannot yet interpret the findings as proof of a cancer risk reduction. The review also addressed the question of whether GLP-1s reduce cancer risk because they cause weight loss and improved metabolism, or because they have a direct anti-cancer effect
A Societal Shift If these treatments like retatrutide do work, they could reduce risks for heart disease and diabetes
The most significant factor is likely related to rapid weight loss and associated nutritional changes
Additionally, Retatrutide enhances protein synthesis & inhibits protein degradation, thereby promoting muscle hypertrophy & reducing muscle wasting
