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.

Chaya Powder is a single-ingredient product: chaya, which is a leafy green vegetable closely related to spinach. The powder form lets you add it to smoothies, soups, or water for convenient use.

There are no inactive ingredients listed in this product.

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 for chaya's effectiveness isn't yet established in the data we hold. Claims exist around its potential to help with nonalcoholic fatty liver disease, cognitive function, muscle strength, obesity, and polycystic ovary syndrome, but the research isn't reliable or complete enough to rate any of these uses.

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.

Chaya is generally well tolerated when consumed as food for most people. It's considered safe during pregnancy and while breastfeeding.

In rare cases, allergic reactions can occur in sensitive individuals, and inhalation of spinach powder (the related ingredient) has been linked to lung inflammation and occupational asthma in factory workers — a concern mainly for those with repeated occupational exposure rather than occasional consumers. Very rarely, the powder form may trigger contact dermatitis on skin.

Side effects, ingredient by ingredient Spinach

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.

Check your exact medications before taking this product if you use blood thinners like warfarin — chaya's vitamin K content can interfere with how they work. Also check if you're on antidiabetes drugs, as chaya may add to their blood-sugar-lowering effect and raise the risk of 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.

Chaya Powder is a nutritious leafy green that works best for people without blood clots or diabetes — or those willing to work closely with their doctor to monitor and adjust medications. If you take warfarin or diabetes drugs, talk with your pharmacist or doctor before starting, since you'll need to keep tabs on how it affects your condition and your prescriptions.

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.

Chaya Powder by TerraVita Premium Collection: Common Questions

Does Chaya Powder by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Chaya Powder 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?
Chaya Powder 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 chaya powder safe to use while I'm pregnant or breastfeeding?
Yes — chaya (spinach-family) as a food is considered safe and even provides folate during pregnancy, and it's safe to use while breastfeeding. If you have specific health concerns, talk with your doctor or midwife.
What is chaya, and why would I use it?
Chaya is a leafy green vegetable related to spinach. People use it as a nutritious food, though the evidence for treating specific health conditions like fatty liver disease or PCOS isn't yet strong enough to confirm how well it works.
Can I use this powder if I'm allergic to spinach?
No — chaya is closely related to spinach, so if you have a spinach allergy, you may react to chaya as well. If you're unsure about a sensitivity, talk with your doctor before trying it.
What are the side effects of chaya powder?
When taken as a food, chaya is well tolerated and side effects are rare. In sensitive people, allergic reactions can happen. Inhalation of spinach powder has been tied to lung inflammation and asthma in occupational settings, though this is uncommon in everyday home use. Contact dermatitis from handling spinach has also been reported rarely.
Do I need to worry about taking chaya with my diabetes medication?
Yes — chaya may lower your blood sugar in the same way your medication does, raising the risk of low blood sugar. Talk with your doctor before starting, monitor your blood glucose closely, and let them know so they can adjust your dose if needed.
I take warfarin for my heart. Can I use chaya powder?
You can, but you need to be careful. Chaya is high in vitamin K, which can reduce warfarin's effect. Daily use for a week can require a dose adjustment. Keep your intake consistent and let your doctor know you're using chaya so they can monitor your blood clotting and adjust your warfarin if needed.
