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.

This product contains one active ingredient: Spinach Flakes Glycerite Liquid Extract, a concentrated form of spinach in liquid form. The only other ingredient listed is glycerin, which is used to extract and preserve the spinach compounds.

You're getting spinach nutrition and its active plant compounds in a liquid format.

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 supporting spinach extract for the conditions listed—including fatty liver disease, cognitive function, muscle strength, weight loss, and polycystic ovary syndrome—isn't established in the data we hold. All six uses show insufficient reliable evidence to rate.

That doesn't mean spinach is ineffective; it means the research so far isn't strong enough to make a confident claim. If you're considering this for a specific health concern, talk with your pharmacist or doctor about what the current science says.

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 and safe for most people. It's also considered safe during pregnancy and breastfeeding as a normal dietary source.

Rare serious adverse effects include methemoglobinemia in infants under 4 months old and allergic reactions in sensitive individuals. Occupational inhalation of spinach powder has occasionally triggered asthma or lung inflammation in workers, and topical contact can cause a rash in some people.

When taken orally as a food or extract, spinach is generally well tolerated.

Meds to double-check

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.

Before you start, double-check your medications in the tool below if you take warfarin (Coumadin) or other blood thinners—spinach can interfere with how they work and may require a dose change. Also flag any diabetes medications: spinach may lower blood sugar, so your doctor might need to adjust your dose to prevent low blood sugar.

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 works best for people who want a concentrated spinach extract and don't take blood thinners or diabetes medications. If you're on warfarin or other anticoagulants, or if you manage blood sugar with medication, check with your pharmacist first—you may need monitoring or a dose adjustment.

Otherwise, spinach is a safe, nutritious supplement for most adults.

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.
Can I take this if I'm pregnant or breastfeeding?
Yes. Spinach is considered safe and nutritious during both pregnancy and breastfeeding. It's a normal food source, so the extract is safe in the same way.
Will this help with my fatty liver disease or cognitive function?
We don't have reliable evidence to say whether spinach extract helps with those conditions. The research isn't strong enough yet to make a confident claim either way. Talk to your doctor about what might work for your specific situation.
What's the difference between eating spinach and taking this liquid extract?
This is a concentrated extract in liquid form, so you get spinach's active compounds in a smaller dose. It's designed to be easier to take than whole spinach, but the basic nutrition and effects are the same.
Are there any side effects when I take it by mouth?
Spinach is well tolerated when taken orally as a food or extract. Allergic reactions are rare but possible in sensitive people. Infants under 4 months old should not receive spinach because of a rare risk of a blood condition called methemoglobinemia.
Can I use this if I'm on blood thinner medication?
Not without checking with your pharmacist first. Spinach is high in vitamin K, which interferes with blood thinners like warfarin. If you take one, you'll need your doctor or pharmacist to monitor you and possibly adjust your dose.
