Analysis

This tablet provides 100 mg of Niacin along with 160 mg of Calcium. This moderate dose is good for individuals who are new to Niacin and want to support their metabolic health without taking a massive amount at once. The inclusion of calcium carbonate helps provide a foundational mineral as part of the daily dose.

Because this form of Niacin can cause a flush, starting at 100 mg is a practical way to test your tolerance. It is one of the most budget-friendly Niacin products on the market, offering reliable quality at a very low price. It is a straightforward tool for supporting circulation and cardiovascular health over time.

  • Supports cardiovascular and metabolic pathways
  • Simple and easy-to-use tablet

Cons

  • Likely to cause a mild skin flush
  • Requires multiple tablets for higher needs

Warnings

  • A warm sensation on the skin is normal at this dose
  • Take with a large glass of water

This basic Niacin supplement provides a low dose suitable for those just starting B3 therapy or looking for mild support. I recommend this for individuals who prefer a tablet form and do not require high-dose therapeutic intervention.
