What is XentaFlex?

XentaFlex is a scientifically crafted powdered dietary supplement developed by Simple Promise to restore and support joint health. Formulated with a potent blend of electrolytic ingredients, XentaFlex is designed to rehydrate cartilage, restore joint fluid, and strengthen connective tissues—supporting greater mobility and smoother muscle function.

This formula is ideal for those experiencing stiffness, discomfort, or reduced range of motion due to aging, physical strain, or past injuries.

The primary goal of XentaFlex is to provide targeted support to the joints by addressing the root causes of joint discomfort—namely, dehydration of cartilage and the loss of natural joint fluid (synovial fluid).

As we age, our joints naturally dry out, making them more prone to friction, inflammation, and pain. XentaFlex helps replenish essential nutrients and electrolytes that contribute to re-lubricating joints, hydrating cartilage, strengthening joint structure, enhancing flexibility and motion, and supporting long-term joint resilience.

XentaFlex comes in a convenient powder form with a refreshing Citrus Mint flavor. This allows for easy daily consumption—just mix a scoop with water or a smoothie for a delicious, hydrating boost. Unlike capsules or tablets, the powder form offers quicker absorption and faster results due to its bioavailable ingredients.

Every batch of XentaFlex is formulated in a GMP-certified and FDA-registered facility in the USA, ensuring the highest standards of safety, purity, and quality.

Simple Promise’s XentaFlex is more than a joint supplement—it’s a proactive solution to joint discomfort and mobility challenges. Whether you’re an athlete, an active adult, or someone managing age-related joint issues, XentaFlex offers a safe, flavorful, and effective way to restore the fluidity and flexibility your body needs to move with comfort and confidence.

How Does the XentaFlex Formula Work?

XentaFlex works by using a powerful blend of electrolytic nutrients and joint-supportive compounds to address the root causes of joint discomfort, stiffness, and reduced mobility. Instead of just masking pain, the XentaFlex formula targets the biological and structural elements that keep joints smooth, flexible, and functional.

As we age or put stress on our joints, the natural lubricant inside them—synovial fluid—begins to diminish. Without this slippery fluid, bones rub against each other, causing pain and inflammation.

XentaFlex’s electrolytic ingredients help stimulate the production and retention of joint fluid, ensuring your joints stay well-lubricated and move more easily.

Cartilage is like a sponge—it needs hydration to stay soft, flexible, and effective at absorbing impact. When cartilage dries out, it becomes brittle and prone to damage. XentaFlex’s hydrating formula supports the absorption of water and essential minerals into the cartilage, restoring its cushion-like properties and helping to prevent further wear and tear.

Healthy joints rely on strong tendons and ligaments for structural support. XentaFlex supplies vital micronutrients and electrolytes that help rebuild and maintain these supportive tissues, improving overall joint strength and stability over time.

With joints rehydrated and connective tissue reinforced, muscles surrounding the joints can work more fluidly. XentaFlex enhances muscle coordination and reduces friction, allowing for smoother movements, reduced stiffness, and improved physical performance in daily activities or workouts.

Unlike temporary pain relief solutions, XentaFlex is designed for daily use to deliver cumulative benefits. Its formula supports ongoing hydration, lubrication, and repair, helping to protect your joints in the long run and minimize future flare-ups or stiffness episodes.

Ingredients in XentaFlex and Their Effects

Here is a detailed explanation of the ingredients in Simple Promise’s XentaFlex formula and how each one contributes to joint support, hydration, and mobility:

AquaLOX® (Patented Boswellia Serrata Extract)

It is a highly concentrated, patented form of Boswellia Serrata, a medicinal plant known for its powerful anti-inflammatory properties.

AquaLOX® targets joint inflammation and pain at the source by inhibiting the enzyme 5-LOX, which contributes to joint swelling and stiffness. Clinical studies show AquaLOX® can significantly reduce joint discomfort and improve mobility in as little as 5 to 7 days.

It helps relieve pain naturally without side effects commonly associated with NSAIDs (non-steroidal anti-inflammatory drugs), supporting smoother joint function over time.

Rejen™ (Patented Fulvic & Humic Acid Complex)

Rejen is a unique blend of fulvic and humic acids derived from ancient plant matter, patented under the name Rejen™.

These compounds act as powerful electrolytic carriers that enhance nutrient absorption, hydrate cells, and detoxify tissues. Fulvic acid, in particular, improves mineral transport into cartilage cells and supports joint fluid production.

Rejen™ restores the electrolyte balance in joint tissues, promoting cellular hydration and repair, while also reducing oxidative stress and cartilage degradation.

L-Taurine

It is a sulfur-containing amino acid naturally found in muscles and the central nervous system.

L-Taurine supports electrolyte balance, helps regulate calcium signaling in muscles, and aids in cellular hydration. It also exhibits mild anti-inflammatory and antioxidant effects. It plays a role in maintaining smooth muscle contractions and reducing stiffness, making it easier for the joints to move freely without strain.

Potassium Chloride

It is an essential mineral and electrolyte that supports numerous physiological functions, including fluid balance and nerve signal transmission.

In XentaFlex, Potassium Chloride supports joint hydration and muscle relaxation, helping reduce cramps and stiffness. Potassium is vital for cellular hydration, which is essential for keeping cartilage spongy and flexible.

Sea Salt (Natural Source of Sodium)

Sea salt is a natural, unrefined source of sodium and trace minerals from the sea. Sodium works with potassium to maintain fluid balance and proper hydration in joint tissues. It also helps in the absorption of nutrients and transmission of nerve signals.

Proper sodium levels ensure that cartilage remains hydrated, reducing friction between bones and enhancing mobility.

Together, these ingredients form a potent, science-backed electrolyte matrix that is a complete joint restoration system built to relieve pain, hydrate cartilage, restore joint fluid, and keep you moving with confidence and ease.

How to Use XentaFlex Supplement?

Using XentaFlex is simple and convenient—perfect for incorporating into your daily routine for consistent joint support.

Take one scoop of XentaFlex powder using the included measuring scoop. Mix it into 8–12 ounces of water, or your preferred beverage such as a smoothie or herbal tea and shake well until the powder is fully dissolved. Consume the drink once daily, preferably in the morning or after light physical activity for maximum absorption and benefit.

XentaFlex comes in a refreshing Citrus Mint flavor, making it enjoyable to drink—no bitter or medicinal taste. Consistency is key—take it daily to maintain hydration and nourishment of joint tissues. If you are pregnant, nursing, or under medical supervision, consult a healthcare provider before use.
