HelloPharmacist Scorecard of Male Vitality by Woodstock Vitamins

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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains 2 active ingredients: LJ100 Eurycoma longifolia extract and PrimaVie Shilajit. The eurycoma longifolia is included to support sexual desire and general vitality, while shilajit is a mineral-rich substance traditionally used for energy and wellness support.

The capsule also contains inactive ingredients — microcrystalline cellulose, dicalcium phosphate, HPMC (a plant-derived capsule material), ascorbyl palmitate, and silica — which serve as binders and flow agents.

Does it work?

Moderate 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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: support vitality and healthy androgen biosynthesis.
  • We looked for evidence on: Age-related testosterone deficiency, Male Infertility, Sexual desire, Sexual dysfunction, Erectile dysfunction (ED), Athletic performance — and 4 related terms.
  • The strongest evidence on file: Eurycoma Longifolia is rated "Possibly Effective" for Sexual desire (Natural Medicines).
  • Also on file: Eurycoma Longifolia is rated "Possibly Ineffective" for Athletic performance.
  • Also on file: Eurycoma Longifolia is rated "Insufficient Reliable Evidence To Rate" for Erectile dysfunction (ED), Muscle strength, Age-related testosterone deficiency, Male Infertility.

Evidence for Eurycoma longifolia supports sexual desire as possibly effective, though it's rated possibly ineffective for athletic performance and there's insufficient evidence for back pain, osteoporosis, or diabetes. For shilajit, the evidence we hold doesn't establish effectiveness for Alzheimer disease, sexual dysfunction, athletic performance, benign prostatic hyperplasia, or osteopenia — the data is insufficient to rate these claims.

The evidence, ingredient by ingredient Eurycoma Longifolia Shilajit

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.

Eurycoma longifolia is generally well tolerated in short-term studies, but long-term safety isn't well established. Because it may raise testosterone levels, if yours climb beyond normal you could develop testosterone-related side effects like acne, insulin resistance, or liver damage.

Shilajit products can vary in purity and may contain heavy metals or contaminants; use only tested, purified brands. One rare case of a severe allergic reaction (anaphylaxis) to shilajit has been reported, and headache occurs rarely.

Avoid this product during pregnancy and breastfeeding — there isn't enough safety data, and both ingredients carry contamination or hormonal risks that make them inadvisable in those periods.

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 — Eurycoma Longifolia, Shilajit.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 333 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 Male Vitality, double-check these with your doctor or pharmacist: propranolol and other beta-blockers (Moderate severity), antidiabetes medications like metformin or glibenclamide (Moderate), and any drugs metabolized by liver enzymes CYP1A2, CYP2C19, or CYP2A6 (Minor). If you take testosterone therapy, confirm as well.

The bottom line

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

Male Vitality is aimed at men looking to support sexual function and vitality, but it's not right for everyone. If you take propranolol, diabetes medications, or drugs processed through your liver's CYP1A2, CYP2C19, or CYP2A6 pathways, or if you're on testosterone therapy, talk with your doctor or pharmacist before taking it.

Use only if you're pregnant or breastfeeding.

LJ100 Eurycoma longifolia extract5 drug types · 248 drugs

Propranolol (Inderal)

Eurycoma longifolia can reduce the levels and clinical effects of propranolol.
A small clinical study in healthy persons shows that taking a single dose of a water-based Eurycoma longifolia extract 200 mg, in combination with a single dose of propranolol 80 mg, reduces the propranolol area under the curve (AUC) by 29%, reduces the peak concentration by 42%, and increases time to peak concentration by 86% when compared with control. Since the elimination half-life of propranolol did not change, it seems that Eurycoma longifolia alters the kinetics of propranolol by decreasing its absorption in the gut, and not by altering its metabolism. It is not known if separating administration will prevent this interaction.

Likelihood Probable Evidence A
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, Eurycoma longifolia might increase levels CYP1A2 substrates.
In vitro research suggests that methanolic Eurycoma longifolia root extract weakly inhibits CYP1A2 enzymes. This effect has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2A6 (Cyp2A6) Substrates

Theoretically, Eurycoma longifolia might increase levels of CYP2A6 substrates.
In vitro research suggests that methanolic Eurycoma longifolia root extract weakly inhibits CYP2A6 enzymes. This effect has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2C19 (Cyp2C19) Substrates

Theoretically, Eurycoma longifolia might increase levels of CYP2C19 substrates.
In vitro research suggests that methanolic Eurycoma longifolia root extract weakly inhibits CYP2C19 enzymes. This effect has not been reported in humans.

Likelihood Possible Evidence D
Testosterone

Theoretically, Eurycoma longifolia may further increase levels of testosterone.
A clinical study in aging males with testosterone levels below 300 ng/dL shows that taking a specific water extract of Eurycoma longifolia roots (Physta; Biotropics Malaysia) 100-200 mg daily with breakfast for 12 weeks increases total testosterone levels by 8% to 11% when compared with placebo. It is unclear whether this increase would occur in individuals with normal testosterone levels.

Likelihood Possible Evidence D

PrimaVie Shilajit1 drug type · 86 drugs

Antidiabetes Drugs

Taking shilajit with antidiabetes drugs might increase the risk of hypoglycemia.
Most human and animal research shows that shilajit can decrease fasting plasma glucose levels. In an animal model, shilajit 100 mg per kg daily enhanced the glucose-lowering ability of both glibenclamide and metformin when given in combination over a 4 week period. Monitor blood glucose levels closely. Dose adjustments might be necessary.

Male Vitality by Woodstock Vitamins: Common Questions

Does Male Vitality by Woodstock Vitamins interact with any medications?
Yes. Based on its ingredients, Male Vitality has a known interaction with 333 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Male Vitality 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.
Will this work for sexual dysfunction?
Eurycoma longifolia is rated possibly effective for sexual desire, so there's some evidence to support that part. Shilajit, on the other hand, has insufficient evidence — we don't have enough reliable data to say whether it helps. Your results may vary, and it's worth discussing your goals with your doctor.
What exactly is shilajit?
Shilajit is a mineral-rich substance, and the form in this product is PrimaVie, which is a purified extract. It's been used traditionally for energy and wellness support, though modern evidence for specific benefits is still limited.
Can I take this if I'm on a blood pressure medication?
If your blood pressure medication is propranolol (Inderal), this product can reduce how well it works. Check with your doctor or pharmacist before starting — they'll need to know about the interaction and may adjust your dose or monitor you more closely.
Are there any side effects I should know about?
The eurycoma longifolia in this product may raise testosterone; if your levels go too high, you could develop acne, insulin resistance, or liver issues. Shilajit is rare but can trigger headaches or, in one reported case, a severe allergic reaction. Use only purified, tested shilajit brands to avoid contamination.
Is it safe during pregnancy or while breastfeeding?
No — there isn't enough safety data for either ingredient during pregnancy or breastfeeding, and both carry potential hormonal and contamination risks. Avoid this product if you're pregnant or nursing and talk with your doctor if you have questions about alternatives.
Should I worry about contaminants in this product?
Shilajit products can pick up heavy metals or other impurities if not properly purified. This product uses PrimaVie, which is a purified form, but the facts note that only tested, purified brands should be used to minimize that risk.
