You're getting 1,000mg of **Calcium** in the citrate form, which absorbs well and doesn't require stomach acid — so you can take it with or without food. That's a full day's RDA in one serving, well above the typical 200–600mg supplemental range. The directions suggest splitting your four tablets throughout the day, and that matters: your body absorbs calcium much less efficiently above 500mg at once, so two tablets twice daily will deliver significantly more benefit than all four together.
The included **Vitamin D3** helps your body actually absorb the calcium — without adequate D, you'd only take in about 10–15% of what's in the tablets. However, the dose is just 600 IU (the RDA), which falls short of the 1,000–5,000 IU range that clinical research supports for maintaining healthy blood levels. If you're relying on this as your only vitamin D source, you'd benefit from a separate supplement to bring your total closer to 2,000–5,000 IU daily.
The four-tablet serving size is worth considering. That's 120 tablets for a 30-day supply, and each tablet is a standard Solgar pressed tablet — if pill burden is a concern, this could feel like a lot alongside other daily supplements.
