A targeted, biologically active trace mineral formulated to lock in calcium, support healthy bone density, ease joint flexibility, and optimize natural hormone metabolism.
Most people focus entirely on calcium and vitamin D when thinking about bone and joint comfort. However, your body requires a specific biological conductor to ensure those minerals actually make it into your bones rather than being flushed away. That conductor is boron. At VitaNet, LLC, our family-owned team has evaluated nutritional formulations for customers across America since 1995[cite: 1]. Over 31 years of hands-on retail operations in Ohio have taught us that mineral form matters just as much as dosage[cite: 1]. NOW Boron delivers a clinically meaningful 3 mg dose in the patented Albion™ Bororganic Glycine form—an organically bound chelate designed for gentle digestion and superior cellular uptake.

How Boron Works in the Human Body: Clear Science in Plain English
Boron is an essential trace mineral that acts as an enzymatic partner for critical metabolic pathways. Even though you only need a few milligrams each day, modern industrial farming practices have substantially depleted soil boron levels, leaving many diets lacking. Here is how 3 mg of daily boron actively supports whole-body health:
Prevents Urinary Calcium and Magnesium Loss: Without adequate boron, your kidneys excrete valuable bone-building minerals. Landmark clinical research led by Dr. Forrest Nielsen at the USDA Human Nutrition Research Center demonstrated that supplementing postmenopausal women with 3 mg of dietary boron reduced daily urinary calcium loss by 44% and significantly lowered urinary magnesium excretion (Nielsen et al., 1987). By keeping calcium and magnesium inside your system, boron helps maintain strong skeletal architecture.
Extends the Life of Vitamin D: Boron inhibits an enzyme called 24-hydroxylase, which normally degrades active vitamin D. By slowing down this breakdown, boron increases the biological half-life and circulating levels of 25-hydroxyvitamin D3, allowing your body to absorb dietary calcium far more efficiently (Pizzorno, 2015).
Maintains Joint Cartilage and Connective Tissue: Pioneering research by Dr. Rex Newnham revealed that populations with higher dietary boron intake have remarkably lower rates of joint discomfort (Newnham, 1994). Boron reduces inflammatory biomarkers like high-sensitivity C-reactive protein (hs-CRP) and tumor necrosis factor-alpha (TNF-α), easing cartilage wear and tear.
Promotes Natural Hormone Balance: Boron plays a vital role in regulating sex-hormone-binding globulin (SHBG). In clinical trials, daily boron supplementation supported healthy free testosterone levels in men and balanced healthy 17-beta-estradiol levels in women, providing endocrine support without introducing external synthetic hormones (Naghii et al., 2011).
Why Form Matters: Albion™ Bororganic Glycine vs. Cheap Boron Salts
Many bargain supplement brands formulate with raw, inorganic boron salts such as sodium borate or boric acid. While these forms are inexpensive to produce, they can break down prematurely in stomach acid, which often causes mild gastrointestinal discomfort and leads to poor absorption across the intestinal wall.
NOW Foods uses genuine Albion™ Bororganic Glycine. Albion Laboratories is the global leader in patented mineral chelation science. In this formulation, each elemental boron molecule is organically bound to the amino acid glycine:
✓ Superior Intestinal Absorption
The human digestive tract recognizes glycine as a nourishing protein building block. It transports the chelated molecule smoothly across the intestinal barrier without digestive resistance.
✓ Stomach-Gentle Tolerance
Because the mineral remains bound to glycine through the acidic stomach phase, it does not irritate sensitive mucosal linings or cause stomach upset.
✓ Zero Mineral Competition
Inorganic minerals frequently fight each other for the same receptor pathways. Chelated glycine shields the boron, preventing it from competing with zinc, iron, or calcium.
NOW Foods Quality Standards: Comprehensive Testing & Strict Contaminant Limits
Because dietary supplements are intended to support lifelong vitality, product purity is non-negotiable. NOW Foods sets an industry benchmark for transparency and consumer safety, operating state-of-the-art analytical facilities accredited to the rigorous ISO/IEC 17025:2017 standard by the American Association for Laboratory Accreditation (A2LA).
NOW conducts over 31,000 individual laboratory analyses and tests every single month, screening incoming raw botanicals, in-process materials, and finished capsules:
Heavy Metal Screening via ICP-MS: Using Inductively Coupled Plasma-Mass Spectrometry, NOW chemists detect toxic heavy metals—including lead, arsenic, cadmium, and mercury—down to parts-per-billion (ppb) thresholds, ensuring levels remain well below strict international safety limits and California Proposition 65 guidelines.
Elemental Potency Verification via ICP-OES: Inductively Coupled Plasma-Optical Emission Spectrometry verifies that every batch contains precisely 3 mg of bioavailable elemental boron, preventing under-dosing or batch inconsistency.
Pesticide and Residue Screening: Utilizing GC-MS/MS and LC-MS/MS instrumentation, NOW screens ingredients against hundreds of common agricultural chemical residues, while Ion Chromatography (IC-MS/MS) specifically checks for glyphosate contamination.
Microbiological Testing: Every lot is screened for pathogen presence, including Salmonella, Escherichia coli, Staphylococcus aureus, total aerobic microbial count, and yeast and mold proliferation.
Raw Material Fingerprinting: Fourier Transform Infrared Spectroscopy (FTIR) chemically fingerprints incoming Albion™ raw materials to authenticate molecular identity before manufacturing begins.
Industry Recognition: In addition to meeting Current Good Manufacturing Practices (cGMP), NOW was honored with the NutraIngredients-USA Industry Initiative of the Year Award for its public efforts exposing substandard, adulterated supplements sold on unmonitored digital marketplaces.

Practical Retailer Guidance: How to Take, Common Mistakes, & Safety Constraints
At VitaNet, LLC, we believe great customer guidance goes beyond reading the label[cite: 1]. Over 31 years of working directly with customers in our Ohio store and online, we have compiled practical rules to help you get the best results while staying safe[cite: 1]:
1. The Golden Rule of Timing: Always Take with Food
While Albion™ Bororganic Glycine is gentle, taking minerals alongside a meal optimizes bile production and stomach acidity, improving mineral assimilation. Taking 1 capsule daily with breakfast or lunch is ideal.
2. Avoid the “More Is Better” Trap: Respect the Upper Limit
The Food and Nutrition Board of the Institute of Medicine established the Tolerable Upper Intake Level (UL) for elemental boron at 20 mg per day for adults. A single 3 mg capsule hits the sweet spot identified in clinical trials. Do not stack multiple boron supplements without clinician guidance.
3. Best Synergistic Pairings
Boron works synergistically alongside Vitamin D3, Vitamin K2, and Magnesium Glycinate. While Vitamin D3 helps your intestines absorb calcium, boron and K2 guide that calcium into your bone matrix and out of soft tissue.
4. Important Cautions and Who Should Avoid Boron
Hormone-Sensitive Conditions: Because boron can influence natural estrogen and testosterone levels, individuals with hormone-sensitive conditions (such as breast, uterine, or prostate cancer, endometriosis, or uterine fibroids) should consult an oncologist or physician before supplementing.
Impaired Kidney Function: Boron is filtered and eliminated primarily by the kidneys. Those diagnosed with chronic renal disease or kidney failure should avoid boron supplementation unless explicitly monitored by a nephrologist.
The VitaNet Guarantee: As an independent retailer founded in 1995, VitaNet stands behind every bottle we ship with an unconditional 100% money-back guarantee, even covering return shipping if you are not fully satisfied[cite: 1].
