If you're new to Intermittent Fasting, you've probably noticed how deceivingly simple it appears. You just don't eat for a little while... right?

But then you're brushing your teeth one night and get a jump - does THIS break a fast?! What about the little bit of lemon you added to your water? Or the Keto Coffee that you're using?!

Probably one of the more confusing factors comes down to vitamins and supplements. It becomes even more tricky when you notice that some supplements and vitamins NEED to be taken with food while others need to be taken fasted. Are these fasted supplements breaking your fast and ruining your results?

Today, I'm breaking down the deets of whether or not supplements and vitamins are breaking your fast.

It Depends.

If we're talking about vitamins in their pure form, such as vitamin C and vitamin D - these do not contain any carbohydrates or protein that can cause the release of insulin and break your fast. The same is true for minerals such as Celtic Sea Salt.

However, if we're talking about supplements such as collagen or protein powder - these not only contain protein that can cause a small insulin release, they often also contain some type of sweetener. The protein and the sweetener both WILL break your fast. That means stirring in collagen to your Keto Coffee is a no-no. (At least during your fasted state.)

It Also Depends On This...

What's your goal with Intermittent Fasting? Are you using fasting for religious purposes or are you on a specific water fasting protocol? If so, then it's possible that ANY food, supplement or drink consumption will break your fast.

But if you're looking to tap into fat burning mechanisms, the goal is to reduce the insulin levels. As we've discussed, insulin is your storing hormone. So while this is high, your body effectively shuts OFF fat burning. That's why the main goal with the Complete Intermittent Fasting Bundle is to stabilize blood glucose levels, reduce insulin and tap into fat burning. This is why Keto Coffee is a great option for those who are new to Intermittent Fasting to utilize during their fasted period. This is also why most supplements, vitamins and minerals will not break your fast.
