Supplements & add-ins
Nine supplements and six fresh add-ins can be blended into smoothies and bowls. Every value below is from the same official nutrition guide as the calculator — including the two numbers most pages never mention: Energizer and Fat Burner publish caffeine values.

Protein math
The two protein powders are not equal: Pea Protein Powder adds 24 g protein for 130 calories, while Whey Protein Powder adds 16 g for 100 calories. Pea is also the dairy-free route — whey lists milk and soy allergens. Vital Proteins Collagen sits between them at 9 g protein for 35 calories. In the calculator, attach any add-in to a smoothie and watch the totals update.
Worth knowing
- Every add-in is a separate upcharge. Prices shown are ranges sampled from two cafés' DoorDash pages in November 2026; your café sets its own.
- Two supplements publish caffeine: Energizer (82 mg) and Fat Burner (50 mg) per serving — see the caffeine page for how that compares.
- Some smoothies already include a supplement in the base recipe; their item pages say so, and the base nutrition already counts it.
- Allergens: whey lists milk and soy; Energizer lists soy; peanut butter lists peanuts; raw almonds list tree nuts. "None listed" is the guide's marker state, not a guarantee — shared blenders are used in cafés.
Frequently asked questions
Which Tropical Smoothie supplement has the most protein?
Pea Protein Powder — 24 g protein and 130 calories per add-in serving, ahead of whey (16 g / 100 cal) and collagen (9 g / 35 cal).
Do supplements cost extra?
Yes. Each supplement or fresh add-in is charged as an upcharge on top of the base item; sampled prices are in the tables above.
Which supplements are dairy-free?
Pea Protein Powder and Vital Proteins Collagen list no milk allergen in the official guide; whey protein is dairy (milk allergen listed). Collagen is animal-derived, so dairy-free but not vegan. See the dairy-free guide for the full picture and cross-contact caveats.
