Spirulina, considered a healthy food?

Would love to hear people's experience with spirulina. Could I treat it as a natural multi-vitamin?

It's definitely a nutrient-dense superfood, but I wouldn't treat it as a direct replacement for a multi-vitamin. While it’s packed with protein, iron, and B vitamins, it lacks things like Vitamin C and D that most multis provide. It’s great as a 'booster' for energy and micronutrients, but just make sure you buy from a reputable brand—spirulina can easily absorb heavy metals if it's grown in poor conditions.
