Solaray Turmeric Root Extract, 300 mg

Our assessment

The evidence shows that this product contains a single ingredient: Turmeric Root Extract at 300 mg per serving. Data on this specific dose and formulation is limited. For the ingredient calcium, which is not present in this supplement, the NIH ODS confirms it supports bone mineralization and neuromuscular relaxation [NIH ODS]. Because the data provided does not include specific studies or adverse event reports for turmeric root extract, we cannot make a strong efficacy claim for this product based on the information supplied.

How it works

You should know that the mechanism of action for turmeric root extract is not detailed in the data provided. For comparison, calcium works through bone mineralization — it supports bone density and mineral deposition, and it also aids neuromuscular relaxation by supporting muscle relaxation and nerve signaling [NIH ODS]. However, since turmeric root extract is a different ingredient, its specific biological actions are not covered in this data set.

Safety profile

Data not available for turmeric root extract specifically. The FDA adverse event database contains a total of 592,059 reports across all supplements, but no specific report count for turmeric root extract is provided [FDA data]. For calcium, which is not in this product, high intakes might increase the risk of heart disease and prostate cancer, and can cause side effects such as constipation, nausea, and abnormal heart rhythms [NIH ODS]. You should be aware of potential interactions: calcium can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS].

Our recommendation

Based on the data provided, we cannot offer a confident recommendation for Solaray Turmeric Root Extract. The 300 mg dose is common, but no studies, efficacy data, or specific safety reports for this ingredient are available in the supplied information. If you are considering this supplement, speak with your healthcare provider, especially if you take any medications, as turmeric can interact with blood thinners and other drugs — though this interaction data was not provided here.
