This Vitamin K supplement was recommended by my doctor to support my eye health, and I've been really happy with it so far. The tablets are small and easy to take, and the 500 mcg dose feels just right. Great value with 200 tablets in one bottle. I’ll definitely keep using it.

Need K to go with my D(s)

If you need a reasonably priced K supplement this is as good as any and it's a small tablet size that is easy to swallow. I usually prefer a Raw K complex but this is just fine - and fit s a tight budget. No taste. Decent Quality.

Good quality

I've only been using this supplement for a short time, but I can already say that Source Naturals is excellent quality. The tablets are small, tasteless, and easy to swallow. The dosage is convenient, not too high, and can be taken daily. The jar is compact, and the lid closes tightly :) So i can recommend

Good Vitamin K supplement

A quality vitamin K tablet that I was taking with my Vitamin D pill, and affordable too. This pill size was easy to take with my morning tea.
