How GLP-1 Therapy Affects Vitamin D

GLP-1 drugs slow gastric emptying, which can alter the absorption of fat-soluble vitamins like vitamin D. Research suggests that the VDR not only mediates vitamin D's effects in tissues but also regulates tight junction proteins in the intestinal barrier, influencing how efficiently vitamin D itself is absorbed in the gut.

Best Foods for Vitamin A on GLP-1

Carrots, 🥬 spinach, sweet potatoes, and 🥚 eggs are among the best practical sources of vitamin A and its precursors. Carrots were commonly eaten in ancient Greece, valued for both taste and color, while 🥬 spinach became a staple in medieval European cooking.

Multivitamin While on GLP-1: Yes or No?

GLP-1 therapy may modestly reduce absorption of fat-soluble vitamins, especially if dietary intake is low. Vitamin D and vitamin A are both fat-soluble and require adequate intake and absorption for optimal function. The morning omelet with 🥬 spinach and orange yolks isn't just breakfast — it's a deliberate act of nutritional architecture, building two critical vitamins into the day before it starts. For anyone on GLP-1 therapy, that small daily choice is one of the most effective ways to keep

👖 Which vitamins are important on GLP-1 drugs?

A morning omelet glistens with bright orange yolks, steamed 🥬 spinach folded in, a glass of whole 🥛 milk beside it — a plate that looks simple but is quietly strategic. For anyone on GLP-1 receptor agonists, this isn't just breakfast; it's a daily check-in with two vitamins that matter more than most people realize.

GLP-1 drugs, which include semaglutide and liraglutide, slow gastric emptying to help manage blood sugar and appetite. That same effect can change how fat-soluble vitamins are absorbed, especially vitamin D and retinoids — the active forms of vitamin A.

🥛 Milk has been a primary source of vitamin D in the American diet since fortification began in the 1930s, a public health response to rickets that made fortified 🥛 milk a staple in homes across the country. Carrots, rich in beta-carotene — the precursor to vitamin A — were consumed in ancient Greece, valued not just for their flavor but for their vibrant color, a sign of nutrient density that ancient cooks understood intuitively.

Cooking technique matters here as much as food choice. Beta-carotene in carrots and leafy greens is more bioavailable when those foods are cooked briefly — heat breaks down cell walls and releases the carotenoids.
