Nutrient quality
Ferrous fumarate and acerola are useful, while zinc oxide is poorly absorbed and the marine and horsetail extracts lack standardization, and the marine complex is substantial, while iron is modest and the horsetail and biotin amounts provide limited depth. The listed amounts are not broadly excessive, though added iron is unnecessary for users without a documented need, while marine protein, iron, zinc, biotin, vitamin C, horsetail, and millet form a coherent hair-support blend.
