Oregon's Wild Harvest Turmeric

Our assessment

The evidence shows that while turmeric is a popular supplement, the data provided here is for the ingredient Calcium, not turmeric. For calcium, our assessment is that it is essential for bone health, but the risks of high intake are significant and require careful management [NIH ODS].

How it works

Think of calcium as a structural builder and signal messenger. It supports bone mineralization for density and mineral deposition, and it aids neuromuscular relaxation for proper muscle and nerve function [NIH ODS].

Safety profile

FDA received 592,059 adverse event reports for this product category. Side effects from high calcium levels include constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [FDA data] [NIH ODS].

Our recommendation

Start with dietary sources first. If you need a supplement, do not exceed the RDA without medical supervision. Separate calcium from medications like bisphosphonates and thyroid hormone by at least 2 hours [NIH ODS].

Supplement labels contain several key sections regulated by the FDA:

• Serving Size — The recommended amount per dose. Always check this — some products require multiple capsules per serving.
• Amount Per Serving — Shows the quantity of each nutrient in the product, typically in IU (International Units), mg (milligrams), or mcg (micrograms).
• % Daily Value (%DV) — Indicates how much a nutrient in a serving contributes to a daily diet. 5% DV or less is low; 20% DV or more is high.
• Other Ingredients — Lists inactive ingredients like fillers, binders, and capsule materials (e.g., gelatin, cellulose, magnesium stearate).
• Suggested Use — The manufacturer's recommended directions for taking the supplement, including timing and dosage.
