Nutrigo Lab Strength Review 2026What Is Inside, and Who It Suits

What is in a serving (from the full label published by the retailer NuviaLab; the German page our link leads to shows only four headline figures): citrulline malate 3 g, arginine AKG 2 g, beta-alanine 1 g, creatine salts giving about 3 g of creatine, taurine, N-acetyl-tyrosine, caffeine 200 mg, bitter orange (about 6 mg synephrine), beetroot, rhodiola and a few more.

What we found:

• The page advertises "4,000 mg creatine"; the label shows about 3,012 mg of actual creatine, because 4,000 mg is the weight of the creatine salts.
• Beta-alanine and citrulline are well below the doses that improved performance in studies.
• It combines caffeine with bitter orange, a pairing Germany's Federal Institute for Risk Assessment associates with heart risks during exercise.

Returns are limited to 10 days from purchase for unopened goods.

Our Dose Check compares each amount with the best human evidence.

• Creatine: about 3 g vs the ISSN's habitual 3 g a day. Adequate for maintenance, but not the advertised 4 g.
• Caffeine: 200 mg vs 3 to 6 mg per kg. At the low end for most adults.
• Beta-alanine: 1 g vs 4 to 6 g a day. 17% to 25%.
• Citrulline malate: 3 g vs 8 g. About 38%.
• Synephrine: about 6 mg, low on its own, but combined with caffeine and exercise.

The directions are two scoops (about 15 g) in 200 ml of water or milk, once a day, 15 minutes before training, and not with other caffeine or before bed. A tub holds about 30 servings.

The cost is about €2.63 or $2.30 a serving. Creatine monohydrate and caffeine bought separately would cost much less.

Our Transparency Score checks five things a buyer can verify. Nutrigo Lab Strength scores 1 out of 5.

• Label with doses: not where you buy. The German page our link leads to shows only four headline numbers; the full label is on a different retailer's store (NuviaLab).
• Identifiable company: no. Key Player Limited, Dubai Airport Freezone on the German site; "NutrigoLabStrength.com", Hong Kong, on the English one. No manufacturer.
• Refund terms in writing: yes. 10 calendar days from purchase, unused goods only.
• Independent testing shown: no.
• Study on the finished product: no.

Other contradictions: the English site's title calls it a "post-workout" supplement while the text says to take it before training; the FAQ says no side effects were found, while the tub carries a caffeine warning; and the page promises no tingling even though beta-alanine is present.

Correction. An earlier version of this review described capsules with creatine monohydrate, whey and ashwagandha, said the doses were within the studied range, and listed a 90-day guarantee and a $42 price. None of this is correct, and we have corrected it.

Prices when we checked in September 2026:

• German site (where our link leads): €78.99 for 1 tub, €157.98 for 3, €236.97 for 6.
• English site: $68.99 for 1 tub, $137.98 for 3, $206.97 for 6.

The return rule. The terms allow withdrawal "within 10 calendar days from the date of purchase", in writing, for goods with no signs of use, and state that EU law does not apply. An opened tub is not returnable under those terms.

• Caffeine: jitteriness, raised heart rate and poor sleep, especially if taken late or with coffee.
• Caffeine plus synephrine with exercise: the BfR associates this combination with cardiovascular risks; the NCCIH notes reports of heart rhythm problems, heart attacks and strokes with bitter orange products.
• Tingling from beta-alanine is possible, though less likely at 1 g.

There is no clinical study on Nutrigo Lab Strength itself.
