An ounce of Swiss cheese has about 25% of the daily recommended intake of calcium.

So, if you're eating 3-4 ounces of cheese daily, in addition to some veggies (spinach and broccoli) you should be fine on the calcium.

From what I've read, the absorption of calcium is more function of Vitamin D levels than anything else. Are you getting enough Sun? If you are, then no worries!

Best of luck,
