HelloPharmacist Scorecard of Vigor Blue by Vigor Labs

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.
  • No proprietary blends here — you can verify the dose of every single component.

Vigor Blue contains 2 active ingredients: glycine and propionyl-L-carnitine hydrochloride. The product also contains inactive ingredients—gelatin, silicon dioxide, and magnesium stearate—which are used to form and stabilize the capsule.

Glycine is an amino acid. Propionyl-L-carnitine hydrochloride is a compound derived from carnitine, which plays a role in how your cells produce energy.

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: Companion supplement for erectile dysfunction treatment.
  • We looked for evidence on: Erectile dysfunction (ED), Age-related testosterone deficiency, Peyronie disease, Sexual function, Penile hemodynamics.
  • The closest evidence on file: Propionyl-l-carnitine is rated "Insufficient Reliable Evidence To Rate" for Erectile dysfunction (ED) (Natural Medicines).
  • Also on file: Propionyl-l-carnitine is rated "Insufficient Reliable Evidence To Rate" for Peyronie disease, Age-related testosterone deficiency.

Glycine is possibly effective for schizophrenia, though the evidence is limited. For 3-phosphoglycerate dehydrogenase deficiency, ADHD, benign prostatic hyperplasia, and cystic fibrosis, there isn't enough reliable evidence to say whether it works.

Propionyl-L-carnitine is possibly effective for ulcerative colitis, heart failure, and angina. Evidence for cardiovascular disease more broadly is also possibly effective, but again limited.

The evidence, ingredient by ingredient Glycine Propionyl-l-carnitine

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Glycine is generally well tolerated at typical doses, but long-term safety data are limited. Rare side effects include mild sedation, irritability, insomnia, fatigue, memory impairment, headache, and sensory impairment—though it's unclear if glycine is the cause.

Soft stools, nausea, vomiting, and upper GI discomfort have also been reported rarely and resolve quickly if you stop taking it. There isn't enough reliable safety data for pregnancy, so it's best avoided unless your doctor approves.

Breastfeeding safety data are also insufficient; caution is advised. Propionyl-L-carnitine is generally well tolerated for short-term use.

Common side effects are diarrhea, stomach pain, nausea, vomiting, and a fishy odor of urine, breath, or sweat. Bronchitis and back pain were reported more often in one clinical trial than with placebo.

It is not safe in pregnancy and should be avoided while breastfeeding.

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?
  • 2 of the 2 matched ingredients can interact with medications — Propionyl-l-carnitine, Glycine.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 20 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 take Vigor Blue, check with your pharmacist if you take clozapine (Clozaril) for schizophrenia, or blood thinners like warfarin (Coumadin) or acenocoumarol (Sintrom), or thyroid hormone replacement. All of these are Moderate interactions with ingredients in this product.

The bottom line

Scorecard at a glanceFully disclosed formula with insufficient evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

If you have schizophrenia and take clozapine, or if you take blood thinners or thyroid hormone, talk to your pharmacist before starting this product. Glycine and propionyl-L-carnitine show some promise for specific heart and digestive conditions, but evidence is limited for many uses.

Your pharmacist can help you weigh whether this is right for you and check your exact medications.

Ingredients driving the most interactions

Each ingredient & the kinds of drugs it affects

For each ingredient in Vigor Blue with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Propionyl-L-Carnitine Hydrochloride3 drug types · 19 drugs

Acenocoumarol (Sintrom)

Theoretically, propionyl-L-carnitine might increase the anticoagulant effects of acenocoumarol.
L-carnitine, the parent compound of propionyl-L-carnitine, might enhance the anticoagulant effects of acenocoumarol, an oral anticoagulant similar to warfarin, but shorter-acting. There are at least two case reports of INR elevation when L-carnitine was taken with acenocoumarol. In one case, a 33-year-old male with a previously stable INR had an elevated INR of 4.65 after L-carnitine was started and continued for 10 weeks. INR normalized after discontinuation of the L-carnitine-containing product. It is unclear if such an interaction would also occur with propionyl-L-carnitine.

Likelihood Possible Evidence D
Thyroid Hormone

Theoretically, acetyl-L-carnitine might decrease the effectiveness of thyroid hormone replacement.
L-carnitine appears to act as a peripheral thyroid hormone antagonist by inhibiting entry of thyroid hormone into the nucleus of cells. Taking L-carnitine also seems to diminish some of the symptoms of hyperthyroidism. It is unclear if such an interaction would occur with propionyl-L-carnitine.

Likelihood Possible Evidence B
Warfarin (Coumadin)

Theoretically, propionyl-L-carnitine might increase the anticoagulant effects of warfarin.
L-carnitine, the parent compound of propionyl-L-carnitine, might increase the anticoagulant effects of acenocoumarol, a shorter-acting oral anticoagulant similar to warfarin. There is not enough information to know whether this interaction occurs with propionyl-L-carnitine and warfarin.

Likelihood Possible Evidence D

Glycine1 drug type · 1 drug

Clozapine (Clozaril)

Theoretically, glycine might decrease the effectiveness of clozapine.
One small clinical study in patients with schizophrenia shows that adding glycine to clozapine therapy worsens symptoms of schizophrenia when compared with clozapine alone. The mechanism of this interaction is unclear.

Vigor Blue by Vigor Labs: Common Questions

Does Vigor Blue by Vigor Labs interact with any medications?
Yes. Based on its ingredients, Vigor Blue has a known interaction with 20 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Vigor Blue 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.
Can I take Vigor Blue if I'm pregnant or breastfeeding?
Not based on what we know. Propionyl-L-carnitine is not safe in pregnancy and should be avoided while breastfeeding. Glycine hasn't been studied enough in pregnancy or while breastfeeding—there isn't enough data to know either way. Talk with your doctor or pharmacist for personalized advice.
What is propionyl-L-carnitine hydrochloride, and what's it supposed to do?
It's a form of carnitine, a compound that helps your cells make energy. In this product it's included for its possibly effective uses in heart failure, angina, and some digestive conditions, though the evidence is limited.
Does glycine help with schizophrenia?
There's some evidence it may help—it's rated possibly effective for schizophrenia. But if you already take clozapine for schizophrenia, adding glycine may actually make symptoms worse, so don't use this product without talking to your doctor first.
What side effects might I get from this product?
Glycine can rarely cause mild sedation, irritability, insomnia, fatigue, headache, or GI upset that usually clears up if you stop. Propionyl-L-carnitine more commonly causes diarrhea, nausea, stomach pain, or a fishy odor to urine, breath, and sweat.
Is this product safe to use long-term?
Glycine is generally well tolerated, but long-term safety data are limited. Propionyl-L-carnitine is well tolerated for short-term use, but talk to your healthcare provider first about extended use.
