Absorbs Like a Sponge

Made with a granulated binding formula to ensure more of the essential nutrients are digested and absorbed.

Maximum Potency

Every batch is 3rd party tested to ensure our tribulus terrestis extract is standardized and confirmed as containing 40% saponins.

Proudly made in the USA and the UK to the strictest of standards

2X more tribulus

We began our journey back in 2005, and ever since, we've been dedicated to producing health supplements that deliver effective results.

Our Double Strength Tribulus and Zinc Magnesium, & B6 formula is designed to be twice as potent as similar supplements, aligning with our mission to help individuals reach their health goals.

Each tablet contains the equivalent of 5000mg of Bulgarian Tribulus Terrestris, providing 500mg of concentrated tribulus extract standardized to 40% Saponins.

You may come across tribulus supplements claiming to contain 50% or more saponins. In most cases, these claims are unlikely to be accurate. Producing a tribulus supplement with a saponin content higher than 40 to 45% is nearly impossible. Often, these companies are obscure brands selling low-quality, generic pills from China, relabeled with their own branding. To ensure authenticity, only consider products authenticated through third-party testing.

Double Strength Tribulus and Zinc Magnesium, & B6 is manufactured in the UK at one of the world's largest facilities, certified by the FDA, adhering to ISO and cGMP standards. Additionally, randomly selected bottles undergo third-party testing for purity and verification.

The natural choice

Double Strength Tribulus and Zinc Magnesium, & B6 is designed to effectively support male health with its powerful combination of high-strength and maximum concentration.

Each tablet not only provides a massive dose of tribulus, advanced extraction and filtration methods ensure the bioactive compounds are not only highly concentrated, but importantly, they remain intact.

We utilize cold process methods including Supercritical CO₂ extraction which is not only eco-friendly, free from toxins and clean, but also prevents active nutrients like Protodioscin, the most powerful Tribulus bioactive, from being destroyed.

If you've tried Tribulus before without results, low quality processing methods could be to blame.

Along with our highly concentrated bioactive Tribulus, each tablet also includes a full daily dose of Boron, Copper, and Zinc Magnesium, & B6, each usually sold as separate supplements.

In the sports nutrition industry, supplements come and go, but Zinc Magnesium, & B6 has been a staple among athletes and gym-goers for over 20 years with good reason. Eliminate the need to buy a second supplement!

Boron and Copper are synergistic nutrients, that help Tribulus and Zinc Magnesium, & B6 do what they do but better.

To round it off, we also included 5mg of Black Pepper Extract in every tablet, ensuring a high absorption rate so you get the most out of every pill.

Making effective health supplements accessible to everyone is at the core of what we do. Our Double Strength Tribulus and Zinc Magnesium, & B6 are powerfully dosed, and affordably priced, with each bottle containing 180 tablets and providing up to six-months supply, allowing for a consistent use.

With this exceptional combination, Double Strength Tribulus and Zinc Magnesium, & B6 stands above all others in its class.

Key ingredients

Tribulus Terrestris Extract 500mg

Tribulus Terrestris extract is derived from the Tribulus Terrestris plant, a small, flowering herb that is native to various regions around the world, including Southern Europe, Asia, and Africa. The extract is obtained from the plant's fruits, leaves, and roots and we source our Tribulus from Bulgaria.

Renowned for its optimal growing conditions and rich history of traditional use, Bulgarian Tribulus sets the gold standard for purity and potency. Its distinct geographical origin, nestled in nutrient-rich soil and under the perfect climate, yields a Tribulus extract with unparalleled saponin content.

Tribulus is often considered a must have amongst gym-goers and athletes alike, due to it’s reputation for boosting performance and promoting an enhanced desire.

Zinc, Magnesium & B6

A potent combination of Zinc Aspartate, Magnesium Aspartate, and Vitamin B6 has long been a staple sports nutrition supplement for good reason.
Athletes and active individuals often have increased needs for zinc, magnesium, and vitamin B6, which are essential nutrients for various bodily functions including muscle repair.

Zinc Magnesium, & B6 supports muscle recovery, restful sleep, and improved performance.

Boron

Boron is a trace mineral found naturally in certain foods and the environment, and it plays a crucial role in various physiological functions.
Boron can help to enhance athletic performance and support muscle growth. Research suggests that boron can positively influence test, which is pivotal for muscle development and overall performance. By promoting hormone balance and optimizing nutrient utilization, boron complements the benefits of Tribulus Terrestris.

Copper

Copper is a fundamental trace mineral that is vital for a range of bodily functions, including energy production, immune system support, and overall well-being. Copper serves several important purposes. Copper is known to contribute to the transport of oxygen to muscles, helping to sustain endurance and enhance physical performance during strenuous workouts. Additionally, it aids in collagen production, supporting joint and connective tissue health, which is essential for injury prevention and long-term athletic durability. By ensuring proper oxygen delivery and promoting joint integrity, copper complements the performance-enhancing properties of Tribulus Terrestris.

Outstanding products

I've been using the keytones for a while and wanted to try these Double Strength Tribulus and ZMA x 180 Tablets (958mg – 40% Saponins with Copper, Boron & Black Pepper) to see if they would be as good and I've not been disappointed. Excellent product which has given me a real boost in energy and focus as well as helping me to stop taking the amyltriptaline I was using for my torn meniscus in my left knee. Sleeping better and I would definitely recommend Pureclinica
