  • Effectively dissolves in about 15 seconds, unlike other brands that take much longer.
  • Accurately labeled as sublingual and quicissolving.
  • Considered the go choice for B12 vitamins.
  • Excellent price point for the product.

Cons

  • Contains Sucralose, which some consumers dislike.
  • Experience of regret for not reading the label before purchasing.
  • Perception that Kirkland brand does not guarantee quality.
  • Dissatisfaction extends to other Kirkland vitamin products, indicating a trend.
  • Overall sentiment of wasted money on the product.

Bottom Line

The Kirkland Signature Quick Dissolve B-12 5000 mcg tablets are praised for their effective and quick dissolving properties, making it a favored choice for B12 supplements.

At an excellent price point, it's worth trying, but be sure to check the label to ensure it meets your preferences.
