How much salt to get a daily 200mg of magnesium?

Magnesium is not typically measured in terms of salt content, as magnesium and salt (sodium chloride) are different minerals. However, I understand that you may be looking for a dietary source of magnesium.

If you are trying to get 200mg of magnesium per day, it's important to note that magnesium is found in a variety of foods, and the magnesium content can vary. Here are some examples of magnesium-rich foods:

Nuts and seeds: Almonds, cashews, and pumpkin seeds are good sources.
Leafy green vegetables: Spinach, kale, and Swiss chard contain magnesium.
Whole grains: Brown rice, quinoa, and oats are magnesium-rich.
Fish: Some types of fish, such as mackerel and salmon, provide magnesium.
Legumes: Beans, lentils, and chickpeas are good sources.
