Dr. Mercola Organic Resistant Starch Complex - Supports Gut & Immune Health - Organic Green Banana, Tigernut Flour & Potato Starch - Gluten-Free & Soy-Free - Unflavored - 9.52 oz (30 Servings)

After having a complete stool analysis done, I knew I needed resistant starches to help feel the bacteria you can’t colonize with probiotics. I mix this with room temperature prune juice (obvious GI issues here), and it seems to be working well so far. I say that because there is definite bloating and has, so that means the bacteria are being fed and it leads me to believe it’s working. I’ll update with new colonization numbers after my next test is completed, but it’s nice to have a ready made supplement to turn to when my green bananas are no longer green to help colonize good bacteria. Can’t comment on regularity changes yet, but hoping once I’ve taken this consecutively for a month I will notice some improvement there too.

Very happy with this product - great for smoothies and the effective it has on my gut health

I think this might have fixed the gut issues I was having for months. I don't need to take this every day now, but it for sure helped when I was having some major issues.

Too expensive for the product. The bag is very small.

Taste a little bit like a banana but not too sweet. Will buy again; helping w gut issues a lot.

I recently read about resistant starch and the possible benefits regarding blood glucose/insulin resistance and additional health benefits concerning digestive system and metabolic health. The nature of the resistant starch enhances the proper environment in the digestive system to sustain the gut microbiome. The Dr. Mercola brand has been around for a while, with a number of products, gaining a favorable reputation and following. So, this specific resistant starch complex was worth testing.This product includes different resistant starches: Type 1, Organic Tigernut Flour; Type 2, Organic Green Banana Flour; Type 3, Organic Pregelatinized Potato Starch. (Another key ingredient: Organic ResistAid Arabinogalactan) Oddly, the full ingredient list is not provided on the product label; The product details states the ingredients: "Organic Resistant Starch, Organic Green Banana, Organic Pregelatinized Potato, Organic Tigernut, Tuber Flour, Organic ResistAid Arabinogalactan".There are 7g of Total Carbohydrates, with 2g of Dietary Fiber. So, that would indicate 5g of Total Sugars (which they conveniently do not list). You would expect a reasonable number of sugars in a starch powder product. I wish they didn't omit this detail, though.As directed on the label, and in online research, the best way to use this product is adding a serving to water or favorite drink, also easily consumed in oatmeal, yogurt or a smoothie. Recommended intake of resistant starches is 15 - 20 grams/daily to support digestive system/bowel health. Using this powder is a very convenient and easy means towards that goal.Resistant starches "functions kind of like soluble fiber. Many studies in humans show that resistant starch can have powerful health benefits. This includes improved insulin sensitivity, lower blood sugar levels, reduced appetite and various benefits for digestion." (online reference).The label does display the badge for USDA Organic. This certification demonstrates the integrity of the ingredients, which checks off an important box for me.The price of $25.50, including the current 15% discount coupon, presents this product as very competitively priced amongst comparable products. It's a good value, especially for organic resistant starch powder.Based on these considerations, this product earns a 4.5 - 4.75 star rating, with a high level recommendation.

I was unable to continue taking this Dr. Mercola Unflavored Organic Resistant Starch Complex due to having horrible stomach problems afterwards. I am not saying for sure that it was this product causing it, because I added a couple of other new items into the smoothie with it. It could have been one of those. The problem was so bad though, that I didn't dare to try weeding things out to see which one was causing the problem. I didn't want to go through that again. What I can say is that this looks similar to a very light colored chocolate and, even though it says "unflavored", it does have a very slight flavor to it. I can't really describe it, but it is nothing bad and will probably not be tasted when adding it to something. I am sure this would probably be fine for people with "normal" stomach/digestive tracts. Mine is not and there are many things that cause me trouble. If you are not someone like me, you will probably be fine.

A good find! Excellent source of prebiotics that don't get expelled, instead stay in your system as probiotic feeders.The other ingredient I appreciate, that many might not know about is the Larch Bark Extract. My friend had the big illness in 2021 and her naturopath recommended Larch Bark extract and Colloidal Silver. She made a complete turn around. Since then, we have kept Larch Bark extract on hand. When our personal bubble becomes bigger in life, we usually take Larch Bark extract for about 3 days after just in case. It has been 2+ years and we have not been sick with that major sickness. Nor have we been sick with anything for years. (We are already grain and no sugar added free and work hard on our gut health, so that helps too.)Dr. Davis recommends prebiotic starch with every meal and this is easy to put in coffee and smoothies. Also feeds reuteri yogurt when fermenting. Overall ... a good find and I recommend it.
