The Protein Recovery Smoothie
with spirulina, hemp seeds and frozen mango
By Superfoods Advisor Editors·July 4, 2026
Allergens Tree nuts
Ingredients
1½ tspSpirulina powderStart at 1 tsp if the flavour is new to you
3 tbspHemp seeds
1 wholeLarge banana, frozen
½ cupFrozen mango chunks
1 tbspAlmond butter
1 cupUnsweetened almond milk
1 tbspRaw cacao powderOptional; adds magnesium and iron
From your pantry
- ½ tspPure vanilla extract
Utensils Blender
Instructions
Add the almond milk and vanilla to the blender.
Add the frozen banana and mango, then the almond butter, hemp seeds, spirulina and cacao on top, so the powders go in last and do not stick to the dry sides.
Blend on high for 60 seconds. The colour settles into a deep green-brown.
Pour into a tall glass, scraping the sides of the jug so none of the spirulina is left behind.
Drink it after training or alongside a meal; there is no need to race a narrow post-workout window.

Why it works
A common reason people abandon spirulina smoothies is the flavour, and the fix is ratio rather than willpower: roughly one part spirulina to two parts frozen mango by volume keeps the drink palatable for a first-time drinker, and the cold from the frozen fruit dulls the bitter notes further.
Spirulina's phycocyanin selectively inhibited COX-2 in isolated-enzyme and human whole-blood assays and also scavenges free radicals (Reddy et al., Biochemical and Biophysical Research Communications, 2000, PubMed:11062000); whether that matters during post-exercise recovery, when inflammatory cytokines are transiently elevated, has not been tested in people. A 2010 double-blind crossover trial by Kalafati et al. in Medicine & Science in Sports & Exercise (PubMed:20010119) found that in nine moderately trained men, 6 g of spirulina per day for four weeks prevented the rise in a lipid peroxidation marker (TBARS) seen after exhaustive running on placebo and modestly lengthened time to fatigue, a preliminary signal that needs larger trials. Dried spirulina is about 57% protein by weight (USDA FoodData Central), with all nine essential amino acids present.
Hemp seeds contribute about 9.5 g of protein per 30 g (3-tablespoon) serving (USDA FoodData Central), with all nine essential amino acids, including the branched-chain amino acids involved in muscle protein synthesis. Timing matters less than often claimed: a meta-analysis of protein-timing trials found that, once total protein intake was accounted for, eating protein close to a training session made no significant difference to strength or muscle gains (Schoenfeld et al., Journal of the International Society of Sports Nutrition, 2013, PubMed:24299050).
Macro detail: about 28 g of the 31 g sugar is fruit sugar from the banana and mango; of the 28 g fat, most is hemp and almond polyunsaturated and monounsaturated fat.
