Helped My Gastritis

I have been battling a gastritis (inflammation of the stomach lining) flare on and off for over a year and today I had a relatively painless day. I have been taking the Algin capsules after meals as directed and the algae reacts to the excess acid in my stomach by turning into a gel, reducing acid levels and making a gel barrier that stops stomach acid from going into my esophagus (aka acid reflux). Both reduce the inflammation. So far the Algin seems to be helping.

However, I was having some side effects and after checking with Dr. Google I found out that I am supposed to wait 30 minutes after the meal and then take two capsules with a glass of water. So, my suggestion is to have some directions on the bottle which reflect this.

Good against acid reflux

Works well against acid reflux, but perhaps not 100%.

joan Lewis

I have been using for awhile (all Nature Sunshine Products) and love it. They all work.

Excellent Product

Happy with my purchase of Algin. It is a first class supplement.

Helps with detox symptoms

Any kind of detoxing makes me so very sick, Algin is the only product I’ve ever heard of that actually mops up the bad stuff and keeps you from getting so sick. It’s best on an empty stomach but can be taken with food, absorbs heavy metals and whatever else is circulating from your detox. It’s also good if you’ve eaten something you wish you hadn’t you can take it with the meal.
