25 Keto Diet Supplements to Strengthen Your Nutrition Game

Let's figure out what supplements are best for you to get the nutrition you need.

One of the first things we often suggest to new keto dieters is getting schooled on supplements – the names and functions of some of the more commonly-used supplements in the low-carb community. 

That’s because most ketoers soon find out that in order to make up the nutritional difference between their previous diets and their new, low-carb keto diet, they need to take supplements.

It’s not the a ketogenic diet isn’t nutritionally sound, or that it lacks anything. It’s just that most new dieters start the diet with a specific goal in mind (like weight loss) and they focus on the goal instead of building the healthiest lifestyle.

So, they often don’t realize that while they’re learning how to plan, shop, and cook for a low-carb keto diet, they need to fortify their nutrition with supplements.

During the initial transition from a high-carb diet to a low-carb keto diet, your body goes through several noticeable changes.

You lose water weight. Restricting your carbs means you’re going to dump some water weight because carbohydrates store water. There’s a great article about this on Paleo Leap that will help you better understand how eating carbs increases the amount of water weight you’re carrying. 

Fewer carbs also means your salt intake has changed. A drop in your sodium can cause an electrolyte imbalance that manifests as keto flu symptoms – headaches, dizziness, brain fog, sluggishness, the shakes. You feel weak and disconnected, in general. Unplugged, if you will. That makes sense, right? An electrolyte imbalance causes a disruption in how your body’s electrical system works. All keto flu symptoms, and most of them can be remedied by adding the right keto diet supplements.

We’ve compiled a list of 25 dietary supplements to fortify your nutrient intake while you’re on a low-carb keto diet.

There are some supplements that provide additional support to those of us who spend lengthy amounts of time in ketosis; they deliver a varied selection of vitamins and minerals. If you include these supplements as part of your daily ritual when you first start the ketogenic diet, you will be in a much better position to manage the effects of the keto flu, which is usually the point at which most would-be ketoers give up.
