The best thing to put in a smoothie depends on what the smoothie needs most. If it needs body, banana or yogurt helps. If it needs sweetness, ripe fruit usually does more than syrup. If it needs freshness, berries or citrus help more than extra sugar ever will.
The mistake is thinking there is one perfect ingredient for every smoothie. There is usually one best ingredient for the problem you are trying to solve.
Quick Answer
Frozen fruit is one of the best things to put in smoothies because it adds cold and thickness at the same time. After that, banana, yogurt, mango, oats, nut butter, and avocado are some of the most useful ingredients because they improve texture and flavor without making the smoothie complicated.
The best ingredient is the one that fixes the weakness in the smoothie you are making.

What It Is / When to Use It
If your smoothies keep turning out thin, bland, too sweet, or too icy, the fix is often not more ingredients. It is choosing one ingredient that does the right job clearly.
Banana helps with sweetness and body. Yogurt helps with creaminess and tang. Oats help with thickness. Nut butter helps with richness. Citrus and berries help brighten a smoothie that tastes too soft.
When you know the specific weakness, choose the fix directly. Use creamier smoothie ingredients for body, natural smoothie sweetness for flavor, and smoothie thickeners when the texture feels loose.
Substitutes / Swaps
If you do not want banana, try mango, avocado, yogurt, or oats for body. If you do not want dairy, coconut milk, plant yogurt, or nut butter can help create a fuller texture.
If you want sweetness without adding sugar, use ripe banana, mango, peach, or pineapple instead of sweeteners first. That usually tastes more natural in a fruit smoothie.

Prep Tips
Choose your add-ins on purpose. One thickener, one brightness booster, or one creamy ingredient is often enough. Too many extras can make the smoothie taste crowded.
Build around the fruit instead of burying it. If the fruit disappears, the smoothie usually stops tasting clean and starts tasting heavy.
If the whole drink tastes dull even after the texture is right, the guide to better smoothie flavor is the cleaner next step.
Storage / Reheat / Freeze
The easiest way to keep smoothie ingredients ready is to portion the useful add-ins with your fruit in freezer packs. That keeps mornings simple and stops you from overbuilding the smoothie every time.
For blended smoothies, remember that heavy add-ins can make the drink thicken more as it sits. Shake or reblend if needed.
