Nutrition Now Calcium + D3 500 mg/1000 IU
Brand: Nutrition Now · Form: GUMMY [E0176] On Market
Our assessment
The evidence shows that this combination supplement provides a useful pairing of two essential nutrients. Calcium at 500 mg supports bone density and muscle function, while 1000 IU of vitamin D3 aids in calcium absorption and immune regulation [NIH ODS]. For many adults, this can be a convenient way to cover a portion of your daily needs, but it is not a complete replacement for dietary sources or a higher-dose regimen if you have a diagnosed deficiency.
How it works
Think of calcium and vitamin D as a team. Calcium is the primary building block for strong bones, and it also plays a key role in nerve signaling and muscle relaxation [NIH ODS]. Vitamin D acts as the gatekeeper — it helps your body absorb the calcium you consume, ensuring it gets deposited into your skeleton rather than being lost. Without enough vitamin D, your body cannot efficiently use the calcium you take in [NIH ODS].
Safety profile
Data not available for this specific product. However, the FDA has received 592,059 total adverse event reports across all supplements. For calcium specifically, high intakes can lead to constipation, nausea, and abnormal heart rhythms [NIH ODS]. You should also be aware that calcium supplements can reduce the absorption of certain medications, including thyroid medication (levothyroxine) and some antibiotics [NIH ODS].
Our recommendation
This product is a reasonable choice if you need to supplement your diet with 500 mg of calcium and 1000 IU of vitamin D daily. Take it with food for best absorption, and separate it from other medications by at least 2 hours [NIH ODS]. If you are taking any prescription medications, especially for thyroid issues or infections, consult your doctor before starting. For most adults, total calcium intake from food and supplements should not exceed 2,000–2,500 mg daily [NIH ODS].
