Understanding the Minimal Magnesium in Cream of Tartar
Cream of tartar, also known as potassium bitartrate, is an acidic powder primarily composed of potassium. While it does contain a variety of other trace minerals, including magnesium, the quantity is exceptionally small and not a meaningful source of the mineral for dietary purposes. According to nutritional data, a typical 100-gram serving of cream of tartar contains only about 2 mg of magnesium. Considering a standard one-teaspoon serving (around 3 grams) used in baking, the magnesium content is reduced to a minuscule 0.06 mg, which represents 0% of the Daily Value.
This small quantity means that relying on cream of tartar for your magnesium intake is not practical or effective. The mineral is listed on nutritional charts, but its contribution is essentially insignificant when consumed in the amounts typically found in recipes. For those seeking to increase their magnesium consumption, the focus should be on foods explicitly rich in the mineral, rather than a kitchen staple used sparingly.
Contrasting Magnesium and Potassium Content
To fully appreciate cream of tartar's nutritional profile, it's helpful to contrast its magnesium content with its dominant mineral, potassium. Cream of tartar is a concentrated source of potassium, which is why it is used in some home remedies for its potential diuretic effects. The difference in concentration is vast, with potassium levels thousands of times higher than magnesium levels in the same serving.
Key Mineral Content Per 100g of Cream of Tartar
- Potassium: ~16,500 mg (16.5 grams)
- Magnesium: ~2 mg
This comparison highlights that cream of tartar's chemical makeup makes it a rich source of potassium, but only a negligible source of magnesium. Consuming large quantities of cream of tartar in an attempt to acquire minerals is not advised and can be dangerous due to the high potassium content, potentially leading to hyperkalemia.
Other Trace Minerals in Cream of Tartar
In addition to potassium and magnesium, cream of tartar contains other minerals, all in small amounts.
- Calcium: Though listed, it provides an insignificant amount of dietary calcium.
- Iron: Contains a small amount of iron.
- Zinc: Present in tiny, insignificant quantities.
Comparison Table: Cream of Tartar vs. High-Magnesium Foods
To put the magnesium content of cream of tartar into perspective, the following table compares the magnesium found in a single teaspoon of cream of tartar with that found in common, magnesium-rich foods. This illustrates how ineffective cream of tartar is as a source of this mineral.
| Food Item | Serving Size | Approximate Magnesium Content | Notes |
|---|---|---|---|
| Cream of Tartar | 1 teaspoon (3g) | 0.06 mg | Trace amount, insignificant |
| Almonds | 1 ounce (28g) | ~80 mg | Excellent source of magnesium |
| Spinach | 1 cup (30g), raw | ~24 mg | Good source of magnesium |
| Avocado | 1 medium | ~58 mg | Good source of magnesium |
| Black Beans | 1 cup, cooked | ~120 mg | High in magnesium |
This table clearly shows that a single teaspoon of cream of tartar offers a negligible amount of magnesium when compared to more robust dietary sources. The discrepancy reinforces the point that cream of tartar is not a functional source of dietary magnesium.
Potential Health Considerations and Risks
While cream of tartar is safe for consumption in the small quantities used for baking, it should not be treated as a mineral supplement. The primary health concern associated with excessive consumption is its high potassium level. Ingesting too much can lead to hyperkalemia, a dangerous condition characterized by abnormally high potassium levels in the blood. Symptoms of hyperkalemia can include muscle weakness, nausea, and an irregular heartbeat. This risk is especially relevant for individuals with underlying health conditions, such as kidney disease, that affect potassium processing.

Conclusion
In summary, cream of tartar contains only trace amounts of magnesium, with an average teaspoon providing a nutritionally insignificant quantity. The mineral content of cream of tartar is overwhelmingly dominated by potassium, with the magnesium and other minerals present in negligible proportions. For those looking to increase their magnesium intake, cream of tartar is not an effective or recommended source. Consumers should rely on foods that are known to be rich in magnesium, such as leafy greens, nuts, and legumes, and use cream of tartar solely for its intended culinary purposes.
