“When fresh spinach sits during transportation over long distances or stays in your refrigerator for a week, its folate content drops so much that frozen spinach becomes the better source,” Mary Ellen Phipps, MPH, RDN, LD, wrote for CNBC in 2022.
This is because frozen spinach often goes through a flash-freezing process just hours after it has been harvested, which helps to lock more of its nutrients in. “One cup of frozen spinach has more than four times the amount of nutrients, including iron, vitamin C, and calcium, compared to a cup of fresh spinach,” adds Phipps. https://vegnews.com/best-form-of-spinach Fresh is Best?

Probably nutritionally similar to frozen. Good to see you’re buying the no salt version.
