HelloPharmacist Scorecard of Up All Night by Ultimate Nutrition Pro Series

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

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 5 active ingredients.
  • “Great Sex 2.0 Blend” is a proprietary blend — the label gives one combined amount (3,307.50 mg) without saying how much of each component you get.

Up All Night contains five active ingredients. Beta-Alanine is an amino acid studied for athletic and physical performance.

L-Arginine is another amino acid that works on blood vessel function. Tongkat Ali root extract and Maca root extract are plant-based ingredients.

Tribulus Fruit Extract is derived from a plant fruit. The product also includes a proprietary blend called Great Sex 2.0 Blend.

Inactive ingredients — the fillers and binders that help form the tablet — include microcrystalline cellulose, stearic acid, croscarmellose sodium, magnesium stearate, silicon dioxide, and pharmaceutical glaze.

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: Male libido enhancement and sexual function.
  • We looked for evidence on: Age-related testosterone deficiency, Antidepressant-induced sexual dysfunction, Erectile dysfunction (ED), Male Infertility, Premature ejaculation, Sexual desire — and 4 related terms.
  • The strongest evidence on file: Tribulus is rated "Possibly Effective" for Sexual dysfunction (Natural Medicines).
  • Also on file: Eurycoma Longifolia is rated "Possibly Effective" for Sexual desire.
  • Also on file: Tribulus is rated "Insufficient Reliable Evidence To Rate" for Erectile dysfunction (ED), Premature ejaculation, Male infertility.

The evidence for this product's ingredients is mixed. Beta-Alanine is possibly effective for athletic performance and physical performance, but evidence is insufficient to rate it for cognitive decline, COPD, cognitive function, or menopausal symptoms.

Tongkat Ali root extract is possibly effective for sexual desire, but possibly ineffective for athletic performance and has insufficient evidence for back pain, osteoporosis, and diabetes. Tribulus Fruit Extract is possibly effective for sexual dysfunction but possibly ineffective for athletic performance, with insufficient evidence for benign prostatic hyperplasia.

For Maca root extract and the Great Sex 2.0 Blend, evidence is insufficient across all rated uses — amenorrhea, anemia, antidepressant-induced sexual dysfunction, athletic performance, and osteoporosis. We hold no effectiveness data for Beta-Alanine's use in sexual function or for L-Arginine's rated uses in this product.

The evidence, ingredient by ingredient Beta-alanine L-arginine Eurycoma Longifolia Maca Tribulus

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 5 of the 5 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 5 of 5.
  • General safety write-ups exist for 5 of 5.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Most ingredients are generally well tolerated short-term. Beta-Alanine commonly causes a harmless tingling sensation (paresthesia) and skin flushing, usually starting on the scalp within 20 minutes and lasting about an hour — severity depends on dose.

L-Arginine may cause abdominal pain, bloating, nausea, diarrhea, headache, insomnia, and flushing, and can lower blood pressure, so it requires medical supervision if you use it for treatment. Tongkat Ali and Tribulus are generally tolerated in studies but long-term safety is uncertain.

Rare serious effects reported with Tribulus include liver and kidney injury and seizures. Maca root extract is generally well tolerated as a food but may cause stomach pain if consumed fresh and uncooked.

None of the active ingredients have adequate safety data in pregnancy or while breastfeeding — the facts advise against use during these periods.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Up All Night may appeal to people looking for athletic performance support or sexual function help, but the L-Arginine, Tongkat Ali, and Tribulus ingredients carry moderate interactions with blood pressure, diabetes, and blood-thinning medications. If you take any prescription drugs — especially for blood pressure, diabetes, or blood clotting — talk to your pharmacist before starting this product.

Long-term safety data are limited for most ingredients.

For each ingredient in Up All Night 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.

L-Arginine9 drug types · 403 drugs

Ace Inhibitors (Aceis)

Theoretically, concomitant use of L-arginine and ACE inhibitors may increase the risk for hypotension and hyperkalemia.
Combining L-arginine with some antihypertensive drugs, especially ACE inhibitors, seems to have additive vasodilating and blood pressure-lowering effects. Furthermore, ACE inhibitors can increase potassium levels. Use of L-arginine has been associated with hyperkalemia in some patients. Theoretically, concomitant use of ACE inhibitors with L-arginine may increases the risk of hyperkalemia.

Likelihood Probable Evidence D
Angiotensin Receptor Blockers (Arbs)

Theoretically, concomitant use of L-arginine and ARBs may increase the risk of hypotension and hyperkalemia.
L-arginine increases nitric oxide, which causes vasodilation. Combining L-arginine with ARBs seems to increase L-arginine-induced vasodilation. Furthermore, ARBs can increase potassium levels. Use of L-arginine has been associated with hyperkalemia in some patients. Theoretically, concomitant use of ARBs with L-arginine may increases the risk of hyperkalemia.

Likelihood Probable Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, concomitant use of L-arginine with anticoagulant and antiplatelet drugs might have additive effects and increase the risk of bleeding.
Preliminary research suggests that L-arginine infusions reduce platelet aggregation in humans. The clinical significance of this effect is unclear.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, concomitant use of L-arginine might have additive effects with antidiabetes drugs.
Preliminary clinical research shows that L-arginine decreases blood glucose levels in patients with type 2 diabetes.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, concomitant use of L-arginine and antihypertensive drugs may increase the risk of hypotension.
L-arginine increases nitric oxide, which causes vasodilation. Clinical evidence shows that L-arginine can reduce blood pressure in some individuals with hypertension. Furthermore, combining L-arginine with some antihypertensive drugs seems to have additive vasodilating and blood pressure-lowering effects.

Likelihood Probable Evidence D
Isoproterenol (Isuprel)

Theoretically, concurrent use of isoproterenol and L-arginine might result in additive effects and hypotension.
Preliminary clinical evidence suggests that L-arginine enhances isoproterenol-induced vasodilation in patients with essential hypertension or a family history of essential hypertension.

Likelihood Probable Evidence D
Potassium-Sparing Diuretics

Theoretically concomitant use of potassium-sparing diuretics with L-arginine may increases the risk of hyperkalemia.
Potassium-sparing diuretics can increase potassium levels. Use of L-arginine has been associated with hyperkalemia in some patients.

Likelihood Possible Evidence D
Sildenafil (Viagra)

Theoretically, concurrent use of sildenafil and L-arginine might increase the risk for hypotension.
In vivo, concurrent use of L-arginine and sildenafil has resulted in increased vasodilation. Theoretically, concurrent use might have additive vasodilatory and hypotensive effects. However, in studies evaluating the combined use of L-arginine and sildenafil for erectile dysfunction, hypotension was not reported.

Likelihood Possible Evidence D
Testosterone

Theoretically, concomitant use of L-arginine and testosterone might have additive effects.
In clinical research, L-arginine increases the level of testosterone in male patients with erectile dysfunction. The clinical significance of this finding is unclear.

Likelihood Possible Evidence D
L-Arginine full monograph & interactions

Tribulus Fruit Extract3 drug types · 259 drugs

Antidiabetes Drugs

Taking tribulus with antidiabetes drugs might increase the risk of hypoglycemia.
Clinical research shows that Tribulus can lower blood glucose levels in adults with type 2 diabetes who are taking antidiabetes medications.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, taking tribulus with antihypertensive drugs might increase the risk of hypotension.
Animal research shows that tribulus can lower blood pressure by inhibiting angiotensin-converting enzyme (ACE). Tribulus has also demonstrated hypotensive effects in pre-hypertensive adults.

Likelihood Possible Evidence D
Lithium

Theoretically, tribulus might increase the levels and clinical effects of lithium.
Tribulus is thought to have diuretic properties. Due to these potential diuretic effects, tribulus might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.

Likelihood Probable Evidence D
Tribulus Fruit Extract full monograph & interactions

Tongkat Ali root 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.

Up All Night by Ultimate Nutrition Pro Series: Common Questions

Does Up All Night by Ultimate Nutrition Pro Series interact with any medications?
Yes. Based on its ingredients, Up All Night has a known interaction with 602 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Up All Night contains 5 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.
What does Beta-Alanine do in this product?
Beta-Alanine is an amino acid that is possibly effective for athletic and physical performance. It's generally well tolerated, but commonly causes harmless tingling (paresthesia) and flushing — especially on the scalp — within 20 minutes of taking it, lasting about an hour. This effect is milder at lower doses.
Will this product help with sexual function?
Tongkat Ali root extract is possibly effective for sexual desire, and Tribulus Fruit Extract is possibly effective for sexual dysfunction. However, the evidence for Maca root extract and the other ingredients in this area is insufficient — meaning we don't have enough solid data to say whether they help or don't.
Is it safe to take this while pregnant or breastfeeding?
No. The safety data advise against use during pregnancy and breastfeeding for Beta-Alanine, Tongkat Ali, Maca, and Tribulus because there isn't enough information to know it's safe. Talk with your doctor or pharmacist for personalized guidance.
What are the most common side effects?
Beta-Alanine commonly causes tingling and flushing. L-Arginine may cause abdominal pain, bloating, nausea, diarrhea, headache, insomnia, and flushing. Tribulus can cause stomach upset including abdominal pain, cramping, nausea, vomiting, diarrhea, and constipation, though in one study these rates were similar to placebo.
How long is it safe to take this product?
Long-term safety has not been well studied for most of these ingredients. L-Arginine requires medical supervision for treatment use. Beta-Alanine safety at high doses long-term isn't established. Tongkat Ali, Maca, and Tribulus have limited long-term safety data — talk with your pharmacist about how long you plan to use it.
What is Tongkat Ali?
Tongkat Ali root extract (also called Eurycoma longifolia) is a plant-based ingredient possibly effective for sexual desire. It's generally tolerated short-term, but long-term safety and product quality can vary. It may theoretically affect how your body processes certain medications through liver enzymes, though this hasn't been documented in humans.
