Vitamins to take with GLP-1 are usually the vitamins you already know about. What changes is when you take them. Take most vitamins with a meal that has some fat. If you take certain minerals as separate supplements, space them out. Ask a pharmacist about any prescription medicine you take.
Why Timing Matters on GLP-1
GLP-1 medicines slow how quickly food leaves the stomach, and many people eat smaller meals. Smaller meals give your body fewer chances to take in nutrients. Good timing helps your vitamins work with the food you eat.
Tip 1: Take Vitamins With a Meal
Vitamin D absorption increased when people took it with a meal that contained fat. Take your vitamins with food that has some fat, such as eggs, yogurt, nuts, or avocado. A small meal can also help if vitamins make you feel sick on an empty stomach.
Tip 2: Space Out Iron and Calcium
Researchers studied how calcium salts change the amount of iron people absorb from food. If you take iron and calcium as separate supplements, take iron with breakfast and calcium with dinner. Leaving at least two hours between them is a practical way to follow this.
Tip 3: Space Out Zinc and Iron When Taken Separately
Zinc can compete with iron and lower how much iron the body absorbs. If you take them as separate supplements, take each one at a different time of day. For example, take iron with breakfast and zinc with dinner.
Some products combine zinc and iron in one formula. Follow that product’s label directions for timing, since the label is written for that exact formula.
Tip 4: Ask About Prescription Medicines
Calcium and iron can change how well some prescription medicines work, including thyroid medicine. Ask your doctor or pharmacist for a timing plan before you start any new vitamin.
