Taking Supplements? How to Time Your Daily Doses
Updated November, 10, 2016
If you take several supplements (like I do), you may wonder:
“Should I take them at the same time each day? Or should I spread doses throughout the day? Should I take with meals? Or on an empty stomach?”
The best answer may depend on whether you are taking medication, on the specific supplement and/or on your personal life style.
Start with the ‘Suggested Use’
Read the supplement label. Some are fairly specific, i.e., “with or without food”, or “with food” or “on an empty stomach”; or specific time (morning or bedtime) or in divided dosages. Make notes for each supplement. Download and use this FREE form to help you keep track of everything.
Do you Have Other Medical Conditions?
If you have diabetes, hypertension or heart disease, first talk to your doctor or pharmacist. Combining supplements with prescription medications, can produce unexpected or life-threatening results.
They may offer advice specific to the combinations of your meds and supplements.
Do Some Reading, Take Some Notes
The best time to take a specific vitamin or supplement may depend on the specific supplement. Do some reading on each at the library or at a reputable website or two. Make notes of the information you find. A few examples:
• Taking a single dose multi-vitamin? It’s best to take it in the morning when nutrients are depleted and with or near breakfast so it’s broken down, then digested with the food.
• Vitamin D is best absorbed after your biggest meal, usually dinner, averaging 56 percent greater boost than those who take it without food.
• Calcium supplement, don’t take along with a multivitamin containing iron. The calcium may interfere with the iron’s absorption.
• Magnesium may be best taken in the evening, since Magnesium may support sound sleep.

On the website Healthy Directions, Dr. David Williams offers advice about the best times to take vitamins. He lists specific vitamins and supplements and organized them into three groups, those that should be taken before meals, with meals, or in-between meals. See his article for specifics, The Best Times to Take Your Vitamins.

My favorite independent research sites
For reliable, unbiased research and information on specific vitamins and supplements, we recommend these three sites (in order or preference). None of the three sell supplements (or anything else). They just offer information on vitamins, herbs, natural products and supplements.
1. Memorial Sloan Kettering Cancer Institute/Integrative Medicine: “About Herbs, Botanicals & Other Products”
2. Drugs.com: ‘MedFacts Natural Products Professional database’
3. The ‘Dietary Supplement Label Database’ at the U.S. National Institutes of Health.
Adjust for Your Life Style
You may need to adjust your supplement taking to accommodate work or school demands, family schedules, etc. For example, if you work the swing shift, your “morning” dose may need to be 1 pm, and your ‘evening’ doze may need to be at 2 am.
Or, if you often skip meals during your work day, taking equally divided doses may become erratic. So, it may be better taking your doses before you go to work.
Bottom Line: Try to be Consistent
For optimum benefit, it may take some effort to work up your supplement schedule. But you don’t have to obsess about it. Since these are ‘natural’ substances (vs. prescription drugs), you usually don’t have to be overly careful about when you take them. What’s important is do try to be consistent from day to day.
After you work out your schedule, consider using a vitamin/supplement organizer. Check out My Search for the Best 7-Day Medicine/Vitamin Organizer.
