This creamy, flax seed smoothie is lightly nutty, naturally sweet from the honey and packed with feel-good ingredients to start your day or for a quick afternoon snack. This is an easy and delicious way to get a health boost of fiber, vitamins and minerals.
- 🍍 Taste & Texture: This smoothie tastes a bit like my pineapple smoothie recipe, full of tropical smoothie flavor but with added nuttiness and a nice kick from the ginger. You will notice a tiny bit of texture from the flax seeds.
- 🍭 Sweetness: Medium sweetness from the honey. You can use unsweetened kefir and adjust the honey amount to taste.
- 🥤 Thickness: On the thinner side, straw-friendly.
- 🥛 Creaminess: Irresistibly creamy from the kefir.
Ingredients
- flax seeds - You can use whole or ground flax seeds, golden or dark brown. There isn't a big difference between golden and brown flax seeds nutritionally, besides the omega-3 fatty acid content, which is higher in golden. Golden seeds are usually more mild in flavor and harder to find in the grocery store.
- pineapple - I like to buy pre-frozen pineapple chunks from the freezer section of the grocery store. This will save you on prep time and is usually cheaper than fresh!
- kefir - Kefir is thinner than regular yogurt and higher in probiotics (3 times more to be precise). If you don't have kefir, you can use ¼ cup of plain yogurt thinned with ¼ cup milk or purchase drinkable yogurt. You can use plain or flavored in this fruit smoothie recipe, whatever you prefer.

How to Make a Flax Smoothie
Step 1. Add ingredients. Add all of the ingredients to a blender or food processor.
Step 2. Blend. Blend until nice and smooth.
Step 3. Serve. Pour into a glass and serve the smoothie immediately. Don't wait to drink this smoothie because the texture can become gel-like as it sits.
Recipe FAQs
Pre-grinding is totally optional but it is helpful for a more smooth blend, especially if your blender isn't very powerful. You can use a coffee grinder or blender; I like to use a magic bullet.
I recommend up to one to two tablespoons per smoothie. You don't want to add too much because the texture can become unpleasant and it can be come sticky/gluey. It's also a high-fiber seed.
Flax seeds are a source of b-vitamins, omega-3 fatty acids and fiber and many more nutrients.
Yes, you can easily swap dairy kefir for a plant-based yogurt or non-dairy kefir. You can omit the honey or use agave nectar instead.
