Suppose that you take your supplements at the same time each day. What should you do on your intermittent fasting days with regard to the supplements? Take them anyway without food, with the next available meal, or just skip them?

I think you need to start with the metabolic goals of intermittent fasting (IF); things like minimizing insulin and blood glucose levels, while also using up at least some of the muscle glycogen stores. Fasting also gives the body's metabolic waste processing systems a little break, since the by-products of digesting food are minimized when you're not eating.

With that in mind, the question about supplements is whether they interfere with the goals. Certainly, if you consume fat in any amount to help increase absorption, or if the supplements are contained in a fat carrier, fat is food, so if you take those, you are no longer really fasting. Some vitamins and minerals can also have a significant effect on various aspects of metabolism.

Based on the above, it seems to me that to eliminate the possibility of accidentally taking something that defeats the metabolic goals of IF, it's probably a good idea to skip supplements too, and just stick with water.

Agree, Rick. Also, you can take vitamin D weekly, so a missing daily dose can be made up any time. – Ed Mar 9 2010 at 2:04
doesn't pure fat not cause an insulin response, because the body doesn't have to process or store it to use it? In the case of a fast being avoiding an insulin response or keeping insulin responses minimal it makes sense to me but I need to look up more info. – Quik77 Apr 12 2010 at 15:43

Any supplements that require, say fat, to be absorbed effectively might as well be skipped I'd say. You'd have to go through your list of supplements and decide on that basis whether or not they would be useful without food.

I take mine regardless of whether I'm fasting or feasting. Then again, I tolerate mine well without food. My wife, on the other hand, needs food in her stomach when she takes them or she'll get nauseous.

And, like Anna said, if there are any that require food, fat, etc, in order to be absorbed properly, you'll need to take that into account. I take mine with a lot of fish oil to help with that.

If you take them with "a lot of fish oil" are you still in a fasting state? – ScottMGS Mar 9 2010 at 0:18
By "a lot of fish oil" I mean 10g, so we're talking less than 100 kcal... hardly enough to make a significant impact on my body's metabolism. For me, I don't necessarily schedule fasting periods and when I am fasting it's not about being in a 100% fasted state, it's about taking in minimal calories, when needed, during the day leading up to the feast in the evening. For example, some days I don't get hungry at all and I'll go all day with nothing more than my morning coffee. Other days I'll lightly graze on nuts or meat taking in maybe 500 - 750 calories throughout the day. – Paleo Dan Mar 9 2010 at 14:01
Yeah,some evenings I'll have a small amount of steamed veggies and not worry about it much. – ScottMGS Mar 10 2010 at 7:36

Curiously my 2-3 days a week IF has morphed into everyday 24 hour fasts. I started skipping breakfast and eating later in the afternoon and this has slowly moved to eating once every 24 hours so I just take my supplements with my evening meal so no problems. This hasn't been a conscious deliberate thing and some days if I get hungry earlier I eat but not often. The lack of hunger is amazing and a heavy workout seems to help even more with it.

That's really interesting Alan. I always assumed that one would get more hunger after a heavy workout (seems intuitive enough), but I've always experienced a suppression of appetite after heavy weights (just like they always said: sciencedaily.com/releases/2008/12/…). Forcing energy into the bloodstream during the exercise explains part of it, but it's more surprising that it would remain afterwards (when presumably energy is being sucked into the muscles). Exercise does clear triglycerides, so maybe that's part of it? – David Moss Apr 2 2010 at 12:19

In the morning I take COQ10 and Vitamin C and the rest at night. The COQ10 shoots my energy through the roof so something needed during the day and not wanted at night. IDK have been losing weight and getting stronger thats all that matters. Did my first good chin up ever. I couldn't even get them back when I was 25lbs lighter 10 years ago.

Taking supplements will not break your fasted state, as long as the supplements you're taking have no caloric density.

For example: fish oils and ClA - no Creatine, caffeine tabs, zero cal BCAAs - yes
