What to Look for in a Clean Pre-Workout (5-Point Checklist)

• Dose transparency matters more than ingredient lists — a label that says "creatine" tells you nothing if the amount is hidden or below clinical range.
• 58% of the top 100 pre-workout products use proprietary blends, hiding individual ingredient amounts.
• "Natural caffeine" from green tea, guarana, or yerba mate is still caffeine — same molecule, same stimulant effect.
• Whole-food ingredients deliver polyphenols and antioxidants a maltodextrin base cannot replicate.
• Third-party certification is the only independent way to verify what's actually in the bottle.

✓  1. Meaningful Ingredient Doses (Not Pixie Dust)

Pixie dusting is listing a high-value ingredient at a sub-therapeutic amount for marketing purposes. Clinical research has established effective dose ranges for the most studied pre-workout actives:

• Creatine Monohydrate: 3–5 g/day — the ISSN position stand identifies this range as the maintenance dose after loading, with research showing 10–40% increases in muscle creatine stores.

• HMB (Calcium): 1.5–3 g/day — a 2025 meta-analysis in Frontiers in Nutrition found 3 g/day for 12+ weeks to be the optimal protocol for muscle mass and strength, with 1.5 g/day showing meaningful strength gains.
• L-Carnitine: 1–2 g/day — a 2021 systematic review in Nutrients linked chronic supplementation at this range to improved high-intensity exercise performance and reduced muscle damage.
• Beetroot/Dietary Nitrate: ≥6 mmol NO₃⁻ (~370mg nitrate) — research in Nutrients (2021) and the Gatorade Sports Science Institute both set 6 mmol as the minimum threshold for ergogenic effect. as the minimum threshold for ergogenic effect.

Is Creatine Safe for Your Kidneys?

A 2025 systematic review and meta-analysis in BMC Nephrology — 21 studies, literature through March 2025 — found that creatine produces a small, transient rise in serum creatinine but no significant change in glomerular filtration rate (GFR), the primary measure of kidney function, across the populations studied. The rise in creatinine is a predictable metabolic byproduct, not organ damage. A 2024 Mendelian randomization study similarly found no causal association between creatine levels and six indicators of renal function. Those with pre-existing kidney conditions should consult a healthcare provider before use.

Dose transparency note: Farmana Workout + Energize discloses all ingredient amounts. Calcium HMB at 1.5g is at the lower end of the cited clinical range (1.5–3g/day). Creatine Monohydrate (900mg) and Carnitine L-Tartrate (380mg) are below the clinical dose ranges cited above — 900mg is well under the 3–5g/day ISSN maintenance range, and 380mg is below the 1–2g/day range studied for carnitine. These doses reflect this formula's positioning as a low-calorie, daily-driver complement to whole-food nutrition. Consumers seeking full clinical doses of creatine or carnitine should supplement those ingredients additionally.

✓  2. No Proprietary Blends

A proprietary blend groups multiple ingredients under one branded name (e.g., "Performance Matrix™ — 3,200mg") with only the total weight disclosed — not individual amounts. Under DSHEA, this is legal. But it makes it impossible to know if any ingredient reaches a clinically meaningful dose.

An industry analysis found 58% of the top 100 pre-workout products used at least one proprietary blend, averaging 14 hidden ingredients per blend. A 2023 study in The Journal of Nutrition found this has barely improved over a decade.

The rule: If amounts aren't listed individually, move on.

✓  3. Whole-Food Foundation

Most pre-workouts are built on maltodextrin, artificial sweeteners, and synthetic dyes — fillers with no nutritional upside. A whole-food base brings something different: pomegranate delivers ellagitannins; beetroot brings nitrates and betaine together; coconut water provides naturally occurring electrolytes.

The clean-label movement in sports nutrition reflects real consumer demand for transparent, minimally processed formulas. Look for: recognizable real-food ingredients, no synthetic dyes (Red 40, Blue 1), and no artificial sweeteners.

✓ 4. Stimulant Status Is Binary

"Natural caffeine" is still caffeine. Guarana seeds can be standardized to 22%+ caffeine by weight. Yerba mate contains caffeine plus theobromine. Green tea extract typically runs 2–4% caffeine. A USDA analysis confirmed that botanical caffeine sources in supplements can deliver hundreds of milligrams even when "caffeine" isn't listed by name.

How to verify: Look for a disclosed total caffeine figure in milligrams from all sources. Truly stimulant-free means <5mg total per serving. (Farmana Workout + Energize contains 50mg Green Tea Extract yielding <1mg caffeine — disclosed.)

✓  5. Clean Label Credentials

These are the minimum quality signals worth checking:

• Non-GMO / Gluten-free / Dairy-free — covers the major dietary restrictions
• No artificial sweeteners (sucralose, aspartame, acesulfame-K) and no artificial colors
• Third-party certified — NSF Certified for Sport and Informed Sport are the gold standards; they verify that label contents match bottle contents and screen for banned substances

This matters because, as USADA notes, supplements are regulated post-market — no agency approves label accuracy before products hit shelves. NSF and OPSS both confirm that independent lab testing is the only reliable way to know what's actually in a product.
