HelloPharmacist Scorecard of Collard Powder by TerraVita Premium Collection
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
Full disclosure
This product contains one active ingredient: collard powder, made from collard leaves and stems. Collards are a leafy green vegetable you might eat fresh or cooked, and here they're concentrated into powder form.
There are no inactive ingredients listed.
Does it work?
Couldn't assess
The evidence we hold shows insufficient reliable data to rate collard for bladder cancer, breast cancer, or prostate cancer. We don't have established effectiveness ratings for other uses in our database.
If you're considering collard powder for a specific health goal, talk it over with your doctor or pharmacist — they can weigh what research exists outside our data.
How safe is it?
Some data gaps
Collard is a common food and is generally well tolerated when eaten in normal food amounts. The safety data supports its use during pregnancy and while breastfeeding in food-based amounts.
We don't have reports of adverse effects from the ingredient in our data.
Meds to double-check
Moderate interaction found
If you take any antidiabetes drugs (blood sugar medications), check your exact medications with the tool on this page before you start. Collard can lower blood glucose, and combining it with your medication could bring levels too low.
The bottom line
Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and some safety-information gaps remain.
Collard Powder is a straightforward, single-ingredient supplement from a vegetable people have eaten for generations. If you take diabetes medications, you'll want to check with your doctor or pharmacist before starting — collard can affect how those drugs work.
Otherwise, it's worth discussing your reasons for taking it with your healthcare provider to make sure it fits your plan.

HelloPharmacist Interaction Report
TerraVita Premium Collection Collard Powder contains one active ingredient — collard leaf and stem powder — and it does interact with a medication type you'll want to check before you start.
Read the full breakdown — every affected drug type, severity by severity
Collard extract can lower blood sugar levels. In animal studies, it worked similarly to glibenclamide, a diabetes medication.
If you take drugs to manage your blood sugar (antidiabetes drugs), collard might add to their effect, which could lower your glucose too much. That's a Moderate interaction — worth a conversation with your doctor or pharmacist before adding this powder to your routine.
Although we hold data on this one ingredient, it does interact with a significant number of individual medications across the antidiabetes class. Run your exact diabetes medications through the search tool below to see if they're affected.

Collard, Powder
Antidiabetes Drugs
In an animal study, an aqueous extract of collard leaves and stems has been shown to reduce glucose levels. Collard extract 60 mg/kg lowers blood glucose levels in a rat model of diabetes after both single- and multi-dose oral administration similarly to glibenclamide 5 mg/kg. Theoretically, collard extract might have additive effects when used concomitantly with antidiabetes drugs and may increase the risk of hypoglycemia. Monitor blood glucose levels closely. Dose adjustments may be necessary. Some antidiabetes drugs include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, pioglitazone (Actos), rosiglitazone (Avandia), chlorpropamide (Diabinese), glipizide (Glucotrol), and tolbutamide (Orinase).
