Compare Sports Research Vitamin K2 180 MCG and 100 MCG softgels to find the right dose for your bone and heart health goals.
Quick Answer
Choose the 180 MCG softgels if you want a higher daily dose in a single softgel; choose the 100 MCG softgels if you prefer a lower dose or a longer-lasting supply.
Understanding the Dose Difference
Vitamin K2 supports bone health and heart health by helping the body use calcium effectively. The two Sports Research options differ in the amount of vitamin K2 per softgel: 180 MCG versus 100 MCG. This difference affects how many softgels you take each day and how quickly you go through a bottle.
If you prefer a straightforward daily routine, the 180 MCG softgels provide a complete dose in one softgel. The 100 MCG softgels offer more flexibility if you want to adjust your intake or split your dose throughout the day.
Bottle Size and Value
The 180 MCG option comes in a 60-softgel bottle, which provides a full month's supply when taken as directed. The 100 MCG option comes in a 360-softgel bottle, which lasts much longer at a lower daily dose. If you plan to take 100 MCG daily, the 360-count bottle offers a long-lasting supply and may be more convenient for refills.
Consider how often you want to reorder. A larger bottle means fewer purchases, while a smaller bottle lets you try the product without committing to a long supply.
Trade-Offs to Consider
- Dose per softgel: The 180 MCG softgel gives a higher dose in one pill; the 100 MCG softgel requires two softgels for the same amount. If you want a single-pill dose, choose 180 MCG.
- Bottle longevity: The 60-count bottle lasts one month at 180 MCG daily; the 360-count bottle lasts about a year at 100 MCG daily. For fewer reorders, pick the 100 MCG 360-count.
- Flexibility: The 100 MCG softgels allow you to adjust your dose more precisely (e.g., 100, 200, or 300 MCG) by taking multiple softgels. If you prefer adjustable dosing, the 100 MCG option is more flexible.
