Prep Tip
Start with small amounts in smoothies — spirulina has a strong, distinct flavor and a 'detox' reaction (headache, nausea) is reported by some people new to it, especially from contaminated or low-quality sources.
Absorption Boost
Vitamin C foods — improves absorption of spirulina's iron
Smoothies with fruit — masks the strong flavor while adding complementary nutrients
Use Caution If
You have an autoimmune condition — spirulina may stimulate immune activity; discuss with a doctor first
You take blood thinners — spirulina has mild effects on platelet activity at high doses
Storage
Store powder in an airtight, opaque container away from light and moisture.
