HelloPharmacist Scorecard of Formula 18 Fat Digest by NESS Nutritional Enzyme Support System
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Low disclosure
This product contains 5 active digestive enzymes. Protease breaks down proteins, lipase breaks down fats, and the others help your body process carbohydrates and plant material.
The inactive ingredients are plant fiber and water.
Does it work?
Not established
The evidence for these enzymes is limited. For lipase specifically, the data shows insufficient evidence to rate it for inflammatory bowel disease, indigestion, or other digestive conditions.
We don't hold effectiveness ratings for the other enzymes in this product.
How safe is it?
Well-documented data
Protease and lipase are generally well tolerated in most adults, though digestive upset or allergic reactions can occur rarely. During pregnancy, protease safety hasn't been established and is best avoided unless your doctor prescribes it; lipase has little safety data in pregnancy, so use only if your doctor advises it.
For breastfeeding, both enzymes have limited safety data — check with your healthcare provider before using. There's a rare risk of allergic reaction to protease, especially in people with occupational exposure to related enzymes.
Meds to double-check
No known interactions
No interactions are documented in our data for the ingredients we could check. That doesn't guarantee none exist — run your exact medications through the tool on this page, and confirm with your own doctor or pharmacist before you start.
