Niacin is converted to NAD and NADP, coenzymes that drive cellular energy production and support normal lipid and circulatory function.
Caution: High-dose niacin may cause flushing, warmth, or itching; take with food and avoid hot beverages or alcohol around dosing to reduce discomfort.
Calcium serves as an essential mineral for muscle contraction, nerve signaling, and vascular tone regulation.
Caution: Calcium carbonate is best absorbed with meals; taking large amounts alongside certain medications may affect absorption, so spacing doses can be helpful.
Niacin supplies coenzymes central to energy metabolism, while calcium supports normal neuromuscular and vascular function. Together they cover cellular energy needs and mineral balance relevant to daily activity.
Label Warning: Consult a healthcare provider before use if pregnant, nursing, taking medications, have a medical condition, or are planning a medical procedure. Stop use and contact a physician if adverse reactions occur. Niacin may cause temporary flushing, itching, and a feeling of warmth.
Who should be cautious: People sensitive to niacin flushing. Those with liver concerns, gout, diabetes, or gastrointestinal sensitivity may need extra caution due to high-dose niacin. If using medications, discuss with a healthcare provider before use.
Storage: Store at room temperature.
Many users mention feeling more energetic and in a better mood after consistent use.
