Rule 1 R1 Citrulline 60 Servings | Pure L-Citrulline Pump Supplement in Pakistan

Rule 1 R1 Citrulline delivers 3g of 100% pure L-Citrulline with nothing else added. No flavors, no sweeteners, no fillers of any kind. Just one ingredient, fully dosed, and ready to drop into any beverage, pre-workout, protein shake, or amino drink without altering the taste of anything it is combined with. This pure L-citrulline powder mixes easily and remains completely unflavored (often searched as r1 citrulline or rule 1 citrulline).

Part of Rule 1's Foundation Series, R1 Citrulline is designed to stand alone as a daily pump and endurance support supplement or be added into an existing stack to extend the benefits of whatever formula it is paired with. Ideal for athletes who prefer citrulline without pre-workout in Pakistan or want a stimulant-free option to customize their stack. Produced in a GMP-certified, FDA-inspected facility in the USA using premium globally sourced ingredients, every scoop carries the same quality and transparency standard Rule 1 is known for across their entire product line. 60 servings per tub. Unflavored. Now available in Pakistan through Fitzone.pk as a trusted L-citrulline supplement Pakistan athletes can rely on.

Key Benefits

Pure L-Citrulline with zero fillers

Every serving delivers a clean 3g dose of pure L-Citrulline with no additives, no artificial sweeteners, no gums, and no flavouring agents of any kind. The formula contains only one active ingredient and Silicon Dioxide as a flow agent. What is on the label is precisely what is in the tub.

Nitric oxide support and muscle pumps

L-Citrulline contributes directly to nitric oxide synthesis in the body. Higher nitric oxide levels promote vasodilation, increasing blood flow to working muscles during training. This supports the intense muscle fullness, surface vascularity, and skin-splitting pump that athletes and bodybuilders train for.

Endurance and performance support

Beyond pumps, L-Citrulline supports workout endurance by reducing the accumulation of ammonia and lactic acid in muscle tissue during high-intensity exercise. This contributes to delayed fatigue onset and the ability to sustain output for longer periods across heavy compound lifts and accessory work.

Unflavored for unlimited stacking versatility

The completely unflavored formula integrates cleanly into any liquid or supplement without adding taste, sweetness, or texture. It works equally well mixed into cold water, protein shakes, pre-workout powders, BCAAs, creatine drinks, or fruit juice. No conflicts, no compromise on the flavour of the supplement it is paired with.

60 servings for consistent long-term use

Each tub provides 60 full servings, giving athletes two full months of daily use at one scoop per day. Citrulline delivers more consistent results with regular daily supplementation, making a 60-serving tub a practical and cost-effective investment for athletes building it into a permanent stack.

Made in the USA in a GMP-certified facility

Rule 1 Proteins manufactures its own formulas in-house in the USA, maintaining complete control over ingredient sourcing, production quality, and finished product standards. R1 Citrulline meets strict GMP-compliance and quality benchmarks from raw ingredient to sealed tub.

Key Ingredients

L-Citrulline (3g per serving)

A non-essential amino acid that converts to L-Arginine in the kidneys, stimulating nitric oxide synthase and driving nitric oxide production. Unlike supplemental L-Arginine, which is poorly absorbed orally, L-Citrulline bypasses liver metabolism and arrives in the bloodstream intact, making it a significantly more bioavailable and effective nitric oxide precursor. It also plays a role in the urea cycle, helping clear ammonia from muscle tissue during exercise and reducing exercise-induced fatigue.

Silicon Dioxide

A food-grade flow agent used in minimal quantity to prevent clumping and ensure the powder flows consistently from scoop to serving. It is the only other ingredient in the formula, confirming the complete absence of fillers, sweeteners, or unnecessary additives.

How to Use

Recommended serving

Mix one scoop (approximately 3.3g) with 240 to 360ml of any cold beverage or liquid workout supplement. Stir or shake until fully dissolved.

Timing

R1 Citrulline is best taken before or during workouts for pump and endurance support. Because it is stimulant-free, it can also be taken at any time of day without affecting sleep or energy levels.

Stacking guidance

Add directly into a pre-workout drink, protein shake, BCAA formula, or creatine solution. Because it is completely unflavored, it dissolves cleanly into any supplement without altering taste. Commonly stacked with R1 Creatine, R1 Glutamine, or an existing pre-workout formula to boost the pump and endurance component of the stack.

Alternative use

Mixes well into sports drinks, smoothies, and fruit juices for athletes who prefer a flavoured delivery vehicle without a dedicated pre-workout product.

Daily consistency

Regular daily use produces more consistent nitric oxide support and endurance benefits than sporadic or occasional use. Building R1 Citrulline into a daily training routine delivers better results over time.

⚠️ Caution: Intended for healthy adults over the age of 18 only. Do not use if pregnant or nursing. Consult a qualified healthcare professional before use if you have any pre-existing medical condition or are taking any medication. Keep out of reach of children. Store in a cool, dry place.

FAQs

What is L-Citrulline and why do athletes supplement with it?

L-Citrulline is an amino acid that the body converts to L-Arginine in the kidneys, which then stimulates nitric oxide production. Higher nitric oxide levels promote vasodilation and increased blood flow to muscles during training. Athletes supplement with it to support muscle pumps, improve blood flow, reduce exercise-induced fatigue, and extend workout endurance. It is more bioavailable than supplemental L-Arginine because it bypasses liver metabolism and enters the bloodstream more efficiently.

How is Rule 1 R1 Citrulline different from citrulline malate?

(citrulline vs citrulline malate) R1 Citrulline uses pure L-Citrulline with no malate (malic acid) bonded to it. Citrulline Malate is a combination of L-Citrulline and malic acid, where the malic acid contributes additional energy support through the Krebs cycle. Pure L-Citrulline delivers the nitric oxide and pump benefits without the malic acid component, making it a cleaner single-ingredient option for athletes who already have energy covered through a pre-workout or other supplements in their stack.

When should Rule 1 R1 Citrulline be taken?

R1 Citrulline is best taken before or during training for pump and endurance support. Because it contains no stimulants, it can be consumed at any time of day without affecting sleep quality. Most athletes add it to a pre-workout drink 20 to 30 minutes before training or sip it as part of an intra-workout formula during the session.

Can Rule 1 R1 Citrulline be stacked with other supplements?

Yes. Its completely unflavored, additive-free formula makes it one of the most versatile supplements available for stacking. It can be added directly to pre-workouts, protein shakes, BCAA drinks, creatine solutions, or plain water. Particularly effective when stacked with a stimulant-based pre-workout to enhance the pump component, or with Rule 1 Creatine and Glutamine as part of a complete foundation stack.

Is Rule 1 R1 Citrulline original on Fitzone.pk?

Fitzone.pk only stocks authentic supplements sourced directly from verified and authorized distributors. Every product is original, properly sealed, and meets full Rule 1 Proteins manufacturing and quality standards. Customers across Pakistan can order with complete confidence.

Love!
Size: 1.7 Fl Oz (Pack of 1)
It’s a little runny but honestly doesn’t bother me at all. Gives me a good glow with a little coverage! Better than any expensive ones I’ve used & layers well with or without makeup. Just wish it was a higher spf but definitely buying again.

So moisturizing
Color: Rose
I love this lip gloss. It is so moisturizing and such a pretty gloss. I don't find it to be very plumping, but it is very hydrating. I love that it's giving me SPF at the same time. I keep one in my purse, one in my car, and one in my swim bag.
