HelloPharmacist Scorecard of Spinach Flakes by TerraVita

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
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

TerraVita Spinach Flakes is a single-ingredient product: spinach extract prepared as a glycerite liquid (meaning it's suspended in glycerin, a natural sweetener and preservative). That's it—no added actives, just concentrated spinach in liquid form.

Glycerin is an inactive ingredient used to stabilize and preserve the extract.

Does it work?

Couldn't assess
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

This is a single-ingredient Spinach product and its label doesn't state a use — see Spinach's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence we hold for spinach on conditions like fatty liver disease (NAFLD), cognitive function, muscle strength, weight loss, and polycystic ovary syndrome (PCOS) isn't established—we have insufficient reliable evidence to rate how well it works for any of these. Spinach is a nutritious food, but as a targeted supplement for these conditions, the science isn't there yet.

The evidence, ingredient by ingredient Spinach

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Spinach as a food is well tolerated by most people and is considered safe during pregnancy and while breastfeeding. Serious adverse effects are rare.

The main concern is in infants under 4 months old, where spinach has occasionally caused a blood disorder called methemoglobinemia (low oxygen in red blood cells). Some people with spinach allergies may have reactions, and inhaling spinach powder (occupational exposure) has been linked to lung inflammation and asthma in sensitive individuals.

Topical contact with spinach can rarely cause skin irritation.

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Spinach.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 88 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Check your blood thinners (like warfarin) and antidiabetes medications (like insulin and metformin) with your doctor or pharmacist before starting Spinach Flakes. Both interact with spinach at Moderate severity.

Blood thinners are the bigger concern—daily spinach intake will require dose adjustment.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Spinach Flakes is a straightforward whole-food extract, well tolerated by adults. If you take blood thinners or diabetes medications, check with your doctor or pharmacist before adding this—it can interfere with both.

For pregnancy and breastfeeding, spinach as a food is considered safe, but confirm with your provider how this concentrated form fits your situation.

Spinach Flakes Glycerite Liquid Extract2 drug types · 88 drugs

Antidiabetes Drugs

There are claims that spinach leaves have hypoglycemic effects. Evidence from clinical research suggests that consumption of a spinach-rich meal reduces post-meal blood glucose levels. Theoretically, spinach might have additive effects with antidiabetes drugs and increase the risk of hypoglycemia. Monitor blood glucose levels closely. Dose adjustments might be necessary. Some antidiabetes drugs include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, pioglitazone (Actos), rosiglitazone (Avandia), and others.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Spinach contains vitamin K, which can interfere with the activity of warfarin.
In human research, although eating spinach with one meal does not result in coagulation test results outside the therapeutic range, daily consumption for one week necessitates dose adjustment of warfarin. Individuals using anticoagulants should consume a consistent daily amount of spinach to maintain the effect of anticoagulant therapy.

Spinach Flakes by TerraVita: Common Questions

Does Spinach Flakes by TerraVita interact with any medications?
Yes. Based on its ingredients, Spinach Flakes has a known interaction with 88 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Spinach Flakes contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Is it safe to take Spinach Flakes while pregnant or breastfeeding?
Yes, spinach as a food is considered safe and provides helpful folate during both pregnancy and breastfeeding. Still, talk with your doctor about whether a concentrated extract form is right for you in these situations.
Can I take Spinach Flakes if I use warfarin?
Not without planning first. Spinach contains vitamin K, which weakens warfarin's blood-thinning effect. Single servings don't cause problems, but daily use for a week or more will require your doctor to adjust your dose. Check with them before starting.
What's the main ingredient in this product?
It's spinach extract prepared in glycerin. There's one active ingredient—spinach—suspended in glycerin to keep it stable.
Will Spinach Flakes help with weight loss or muscle strength?
The evidence isn't there yet. We have insufficient reliable data to know whether spinach works for weight loss, muscle strength, or several other conditions people ask about.
Are there any common side effects from taking spinach?
When spinach is consumed as food, it's well tolerated by most adults. Serious adverse effects are rare. People with spinach allergies may react, and inhaling spinach powder can cause lung problems in sensitive individuals.
