HelloPharmacist Scorecard of SyntraEC by Syntrax

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.

From our pharmacy team — supplement deep dive

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 2 of its 2 active ingredients.
  • “Cyanotis vaga root extract” is listed as a grouped ingredient — the label gives one combined amount (275 mg) without saying how much of each component you get.

SyntraEC has 2 active ingredients: 20-Hydroxyecdysterone and Cyanotis vaga root extract (which contains ecdysteroids). These compounds are plant-derived substances sometimes used in sports and fitness contexts.

The product also contains several inactive ingredients — cellulose, gelatin capsules, and a few other stabilizers — to hold everything together and keep it shelf-stable.

Does it work?

Insufficient evidence
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
Insufficient

There isn't enough reliable clinical evidence to rate this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: muscle building, strength and athletic performance.
  • We looked for evidence on: Athletic performance, muscle mass, muscular strength, athletic endurance.
  • The closest evidence on file: Ecdysteroids is rated "Insufficient Reliable Evidence To Rate" for Athletic performance (Natural Medicines).

The evidence for ecdysteroids in athletic performance, diabetes management, and Parkinson disease is currently insufficient to rate — meaning we don't have enough reliable data to say whether SyntraEC works for any of those uses. If you're considering it for a specific reason, that's something to discuss with your doctor or pharmacist, who can point you toward what's actually known.

The evidence, ingredient by ingredient Ecdysteroids

How safe is it?

Some data gaps
Safety Information · database check
Some gaps

Safety data exists for these ingredients, but with some important gaps.

Why this rating?
  • We hold adverse-effect (side-effect) data for 0 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.

Short-term use of ecdysteroids appears generally well tolerated in small studies, but long-term safety hasn't been established, so there's a real gap in what we know if you plan to use this long-term. There isn't enough safety information for pregnancy or breastfeeding — the data advises against use in both.

If you're pregnant, planning to become pregnant, or breastfeeding, talk with your doctor or pharmacist before taking this product.

Meds to double-check

No known interactions
Known Interaction Concern · database check
No known interactions

No medication interactions are currently documented for the matched ingredients — that isn't a guarantee none exist.

Why this rating?
  • None of the 1 matched ingredient has a documented medication interaction on file.

No interactions are documented in our data for the ingredients we could check. Still, check your exact medications with the search tool on this page before you start, since we couldn't verify one of the two active ingredients.

The bottom line

Scorecard at a glanceFully disclosed formula with insufficient evidence for its stated purpose. No medication interactions are currently documented, and some safety-information gaps remain.

SyntraEC is an ecdysteroid supplement with no documented interactions with medications we could check. If you're interested in it for athletic performance or another specific reason, have a conversation with your pharmacist first — the evidence for its effects isn't established yet, and long-term safety data is limited.

SyntraEC by Syntrax: Common Questions

Does SyntraEC by Syntrax interact with any medications?
We do not currently list a known interaction for the mapped ingredients in SyntraEC. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
SyntraEC contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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 SyntraEC long-term?
Short-term use appears generally well tolerated in small studies, but long-term safety hasn't been established. If you're planning to take it for months or longer, that's a good question to bring to your pharmacist or doctor.
Can I take SyntraEC while pregnant or breastfeeding?
No — there isn't enough safety information, so the data advises against it during pregnancy and while breastfeeding. Talk with your doctor or pharmacist if you're in either situation.
Does SyntraEC actually improve athletic performance?
The evidence right now is insufficient to rate — meaning we don't have enough reliable data to say whether it works. It's worth asking your pharmacist or doctor what the current science actually shows.
What are these ecdysteroids, anyway?
They're plant-derived compounds found in things like Cyanotis vaga root. They're sometimes marketed in fitness supplements, but the evidence for what they actually do in people is still uncertain.
Does this product have a lot of fillers?
It has the usual inactive ingredients you'd find in a capsule — cellulose, gelatin, and a couple of stabilizers like silicon dioxide. Nothing unusual for this type of supplement.
