The Ultimate Smoothie Add-Ins for a Nutrient Boost

Smoothies are my go-to when I need fast, powerful nutrition. But what really makes them work for me are the add-ins. These are the ingredients I toss into my blender for an extra nutrient boost. They may be small, but their impact is huge. Today, I’m going to walk you through the ultimate smoothie add-ins I rely on for energy, skin health, gut health, and total body nourishment.

Why Add-Ins Matter

A banana, a handful of berries, and some almond milk make a good smoothie. But add one tablespoon of chia seeds or a scoop of collagen, and now it’s a super-smoothie. Add-ins raise the nutritional profile of my drink without changing the taste too much.

They support:

• Immune health
• Skin, hair, and nails
• Muscle recovery
• Brain function
• Energy levels
• Digestive balance

Every smoothie becomes a tailored treatment for my body.
