Boron Citrate

Primabolics Boron Citrate is a single-ingredient, bioavailable boron supplement delivering 3mg of elemental Boron (as Boron Citrate) per vegetarian capsule — with zero fillers and zero additives. Boron is a trace mineral found naturally in fruits, vegetables, nuts, and legumes, and has attracted significant research interest for its role in bone metabolism, hormonal regulation, cognitive function, and the metabolism of key minerals including calcium, magnesium, and Vitamin D. The citrate form is used for its superior bioavailability compared to boric acid. Australian owned and manufactured, with complete label transparency.

Why Primabolics Boron Citrate?

3mg Elemental Boron Per Capsule: Delivering the most widely studied supplemental dose of elemental Boron — 3mg per capsule — in the highly bioavailable citrate form. No fillers, no blends, no hidden additives.

Citrate Form — Bioavailable Boron:

Boron Citrate is a well-absorbed organic boron compound, offering superior bioavailability compared to inorganic boron sources such as boric acid.

Bone & Mineral Metabolism Support:

Boron is involved in the metabolism of calcium, magnesium, and Vitamin D — three key nutrients for bone mineral density and skeletal integrity. Research suggests boron may support the retention of these minerals in bone tissue.

Hormonal Environment Support:

Boron has been studied for its role in supporting healthy testosterone and oestrogen metabolism, with research suggesting it may influence the activity of sex hormone-binding globulin (SHBG) and the conversion of Vitamin D to its active hormonal form.

Cognitive & Brain Function:

Boron has been identified as a bioactive trace mineral with roles in brain electrical activity, cognitive performance, and psychomotor function — areas that are increasingly recognised in nutritional neuroscience.

120 Capsules — 120 Full Serves:

One capsule per serve, providing a generous 120-day supply at the standard daily dose.

Vegetarian Capsule Shell:

Encapsulated in a vegetarian Hydroxypropyl Methylcellulose (HPMC) capsule — suitable for vegetarians.

Zero Energy, Zero Macros: Zero protein, zero carbohydrates, zero fat, zero sugar, and zero sodium per serving.
Australian Owned & Manufactured: Formulated and produced locally to the highest manufacturing standards, with complete label transparency.
About Boron Citrate

Boron is a naturally occurring trace mineral found in plant-based foods including fruits, vegetables, nuts, and legumes. While it has not yet been classified as an essential nutrient in the traditional sense, a substantial body of research has identified boron as a bioactive trace element with wide-ranging physiological roles. Boron influences the metabolism of calcium, magnesium, phosphorus, and Vitamin D — nutrients critical to bone health and hormonal function. Research has shown that boron supplementation can support the maintenance of serum levels of these minerals, and may influence the activity of steroid hormones including testosterone and oestrogen by modulating SHBG and supporting the conversion of Vitamin D3 to its active hormonal form (1,25-dihydroxyvitamin D). Boron has also been studied for its role in brain function, with research linking adequate boron intake to improved cognitive performance, attention, and psychomotor function. As a dietary supplement, Boron Citrate is widely used by athletes, health-conscious individuals, and those seeking to support bone health, hormonal balance, and cognitive vitality as part of a balanced diet and lifestyle. It is commonly stacked with Vitamin D3 + K2, Zinc, and Magnesium as part of a comprehensive micronutrient protocol.
