FREQUENTLY ASKED QUESTIONS

What should I eat or take to support my workout?

Unbox Health FAQ Icon

Workout performance and recovery are usually supported through Creatine Supplements, Electrolytes, Protein Powders, Plant Protein Powders, Peanut Butters, Protein Bars, Energy Bars and Protein Milkshakes. ICMR-NIN's protein guidance applies to the powder and bar options here, while Creatine Supplements and Electrolytes are governed more by sports nutrition research than standard Indian dietary allowances, since neither is classified as an essential daily nutrient.

Should I take Creatine Supplements or rely on Protein Powders for muscle gains?

Unbox Health FAQ Icon

They work differently and are not interchangeable. Creatine Supplements support short bursts of strength during resistance training, while Protein Powders supply amino acids for muscle repair afterward. Most people benefit from combining adequate daily protein with creatine rather than choosing one. Check Unbox Health's lab-tested data to confirm actual creatine purity across brands in this collection first.

Is creatine safe to use daily, and does it damage the kidneys?

Unbox Health FAQ Icon

Current evidence does not support kidney damage from creatine use in healthy individuals at standard doses of around 3 to 5 grams daily. Creatine can raise serum creatinine, a kidney-function marker, without indicating injury, which can confuse blood test results. This concern applies to people with pre-existing kidney disease, who should discuss it with a doctor. ICMR-NIN has not issued formal creatine guidance, since it is not an essential nutrient.

Why do Indian athletes and gym-goers need Electrolytes in addition to water?

Unbox Health FAQ Icon

India's heat and humidity can increase sweat loss during workouts, though the amount varies by person and intensity, sometimes depleting sodium, potassium and magnesium faster than plain water replaces them. Electrolytes help restore this balance during longer or high-intensity sessions, generally beyond about an hour. ICMR-NIN does not set a specific electrolyte guideline, but general hydration and mineral intake recommendations apply, making food-based sources a reasonable option for shorter workouts.

Is it true that creatine causes water retention that ruins muscle definition?

Unbox Health FAQ Icon

Creatine does draw some water into muscle cells, which is often mistaken for unwanted bloating rather than the intended effect of increased cell volume linked to strength gains. Current evidence does not support broad, visible water retention outside the muscle in most users at standard doses. This effect tends to ease within the initial weeks of use and is not the same as generalised fluid retention.

Do I need both Protein Powders and Energy Bars, or does one cover my needs?

Unbox Health FAQ Icon

It depends on your training goal. Protein Powders and Milkshakes suit post-workout muscle repair, while Energy Bars work as pre-workout fuel and Peanut Butters serve more as a steady source of energy through fat content. Someone training most days may need both at different points, while occasional gym-goers can usually manage with one. Compare which brands actually deliver their declared protein and energy content on Unbox Health before stacking products.

How should I time Creatine Supplements and Protein Powders around a workout?

Unbox Health FAQ Icon

Creatine Supplements do not need precise timing since their benefit builds up with consistent daily use rather than a single dose window. Protein Powders and Protein Milkshakes are commonly taken within a couple of hours after training to support recovery, though total daily protein intake matters more than exact timing. Keep both consistent day to day and adjust only if digestion feels off.

What should I check on Protein Bar and Energy Bar labels before buying?

Unbox Health FAQ Icon

Check the added sugar content first, since many Energy Bars and Protein Bars marketed for fitness carry sugar levels closer to a dessert than a sports product. Compare declared protein grams per serving rather than per bar weight, as serving sizes vary across Protein Bars and Protein Milkshakes. FSSAI requires this information on packaging, but declared figures are not always independently confirmed against lab results.

Who should be cautious with Creatine Supplements or Electrolytes?

Unbox Health FAQ Icon

People with pre-existing kidney disease should avoid Creatine Supplements without medical clearance, and those managing high blood pressure should check sodium content in Electrolytes before regular use. Anyone with a heart condition should discuss Electrolyte supplementation with a doctor, since excess potassium or sodium intake can affect cardiac rhythm. This caution applies specifically to these conditions, not to healthy adults training normally.

How can I confirm a fitness supplement actually contains what the label states?

Unbox Health FAQ Icon

Creatine purity and Protein Powder content are commonly misrepresented claims in Indian sports nutrition, since manufacturing standards vary widely across brands. Check Unbox Health's lab-tested data to compare which brands in this collection actually deliver the creatine purity or protein content they advertise, rather than assuming a higher price or bigger label claim means better quality.
