“I feel more energy from the iron supplement and it doesn’t upset my stomach at all. I don’t like swallowing pills, but have not had issues with any of these three.”

Kristin T. (Verified Customer)

“I felt the difference very quickly, especially with my digestion and metabolism. The biggest impact has been hormonally”

Marilie C. (Verified Customer)

“The pills are easy to swallow and not too big... I noticed that I am able to recover from my workouts faster, and my muscles aren't as sore."

High quality, bioavailable forms in a precision AM/PM dosing protocol

Designed for maximum absorption to support daily energy, maintain strong, healthy bones, and promote long-term resilience for women who seek Performance for Life™.

A Commitment to Excellence

Designed to set a new standard—The Momentous Standard™— in women’s foundational health.

Developed with Leading Experts 

The Women’s Three™ was developed in partnership with leading female physiology expert Dr. Stacy Sims, and supported by a team of specialized dietitians. We led with science that centers women’s unique physiological needs—factoring in menstruation, bone density changes, common deficiencies, and menopause—to build a truly foundational system that supports Performance for Life™ through every stage.

Focused on the Fundamentals

We targeted three of the most impactful nutrient needs to support daily energy, bone health, and healthy aging at all stages of life. It’s what makes The Women’s Three™ truly foundational:

  • Iron to support red blood cell production, energy levels, and enhanced cognitive function.
  • Calcium to protect bone health, strength, and muscle function to combat age-related bone density loss.
  • Vitamin D3 to enhance immune health, muscle function, and manage inflammation.

Formulated for Impact
We use only the most bioavailable, science-backed forms of each nutrient, supported by clinical research and paired with supplemental ingredients to boost absorption and efficacy:

  • Ferrochel® Iron (Ferrous bisglycinate chelate): gentle on the gut, highly absorbable, with added Vitamin C to further aid absorption.  
  • DimaCal® Calcium (Dicalcium malate): highly bioavailable, concentrated, and well-tolerated.
  • D3 (cholecalciferol): the most potent and easily absorbed form of Vitamin D, in a capsule with organic extra virgin olive oil for optimal absorption.

Smarter by Design

The Women’s Three™ is a strategically designed daily protocol: the AM dose consists of Iron+, which is Iron with Vitamin B complex, including Vitamin C for enhanced absorption, and the PM dose consists of Calcium and Vitamin D3, which comes dissolved in organic extra virgin olive oil to aid absorption with or without food. The timing helps prevent nutrient interference (Iron and Calcium compete for absorption), which means increased absorption, fewer side effects, and more benefit.

Put to the Ultimate Test

Every ingredient in The Women’s Three™ is NSF Certified for Sport®, the gold standard in independent testing. It’s not the industry norm—it’s The Momentous Standard™. That means:

  • Suitable for professional and Olympic athletes
  • Verified label accuracy
  • Guaranteed purity and potency

Iron+
With Vitamin C to enhance absorption + B Complex to support energy.

  • Supports natural energy by helping carry oxygen throughout the body
  • Reduces fatigue and boosts stamina, especially during menstruation
  • Enhances physical performance, improves VO₂ max and time-to-exhaustion
  • Aids cognitive function, focus, and mental clarity
  • Helps prevent deficiency, which is common in women due to menstruation, pregnancy, and lower iron intake
  • Ideal for athletes, plant-based eaters, and anyone with high iron demands

Calcium
With Dicalcium Malate for optimal absorption and digestion.

  • Supports bone strength and density, helping reduce fracture risk and protect against osteoporosis
  • Helps slow mineral loss in women at risk of age-related bone decline
  • Aids in muscle contraction, relaxation, and recovery, boosting strength and post-workout performance
  • Prevents cramping and reduces injury risk by supporting neuromuscular function
  • Enhances coordination, reaction time, and total-body movement
  • Plays a key role in nerve signaling for sharp, efficient brain-body communication


Vitamin D3 (2000 IU)
With organic extra virgin olive oil for optimal absorption.

  • Enhances calcium absorption to support bone density and reduce fracture risk
  • Especially important for women postmenopause, with low sun exposure, or at risk for bone loss
  • Supports muscle contraction, coordination, and recovery, improving strength and reducing soreness
  • Aids balance and movement by activating Vitamin D receptors in muscle tissue
  • Strengthens immune response by regulating inflammation and pathogen defense
  • Helps prevent common deficiencies that can compromise long-term health and resilience

Frequently Asked Questions

This system was developed for women across all life stages and designed to support three of the most critical nutrient needs for women. The Women’s Three™ supports daily energy, bone health, and long-term resilience. It is especially beneficial for those with high physical demands, low iron intake, or increased calcium needs.

The Women’s Three™ is intended to support women’s nutrient needs across all phases of life, but individual requirements may vary during pregnancy and postpartum. Please consult your healthcare practitioner.

Iron and Calcium compete for absorption, while Vitamin D3 helps to aid absorption of Calcium, so the targeted timing protocol maximizes impact and efficacy. Iron+ is taken in the morning, while Calcium and D3 are taken in the evening.

Iron is best absorbed on an empty stomach, and our Iron+ includes Ferrochel® Iron (Ferrous bisglycinate chelate), which is gentle on the stomach. Our Iron does include Vitamin C to aid absorption, so food is okay if needed. Calcium and D3 are well absorbed with or without food.

Yes. The Women’s Three™ supports key nutrient needs during perimenopause and menopause, including declining bone density, reduced iron stores, and changes in energy metabolism. Its bioavailable forms of Iron+, Calcium, and D3 are formulated for optimal absorption and long-term health. Individual requirements may vary, so please consult your healthcare practitioner.

Results vary by individual, but many customers report improved energy and recovery within a few weeks. Bone density and immune benefits build over time with consistent use.

Each ingredient in The Women’s Three™ is chosen for its superior bioavailability and impact. 

Iron+ features Ferrochel® Iron (ferrous bisglycinate chelate), a highly absorbable, gentle-on-the-stomach form of iron—combined with Vitamin C to enhance absorption and a full B Complex to support energy. 

The Calcium comes as DimaCal® (dicalcium malate), a highly concentrated, well-tolerated form that is easy to absorb. 

Our Vitamin D3 2000IU (cholecalciferol) is delivered in a hard-shell liquid capsule, eliminating the need for bovine collagen used in softgels. It also includes  organic extra virgin olive oil, which naturally improves absorption and efficacy. 

There are no unnecessary ingredients —just clinical-grade forms your body can actually use.

Yes! Our Iron+, Calcium,  and Vitamin D3 2000 IU products are all both GMO Free, Gluten Free, and Vegan.

Each capsule provides 250 mg of elemental calcium from DimaCal—a highly bioavailable, dairy-free form that delivers more usable calcium with fewer GI side effects. For most people, one capsule daily is ideal, especially when combined with a balanced diet. Our formula is intentionally designed for flexible titration, allowing you to adjust your intake based on diet, age, training load, or hormone shifts. If your daily needs are higher, it’s safe to take additional capsules as recommended by your healthcare provider.

Not necessarily. The idea that Vitamin D3 must always be paired with Vitamin K2 to “move calcium into the bones” is a common myth, not a medical requirement. Most healthy people already get enough Vitamin K through diet-leafy greens supply K1, and foods like eggs, dairy, and fermented dishes provide K2. Your body can also convert some K1 into K2 as needed.

Clinical research shows that Vitamin D alone does not cause calcium to build up in arteries, and routine Vitamin K supplementation isn’t necessary unless you have a known deficiency.

At Momentous, our Vitamin D3 is formulated for optimal absorption and real-world effectiveness. Delivering what your body needs, without unnecessary additives or marketing hype.

Yes. Every product in The Women’s Three™ is NSF Certified for Sport®. NSF Certification ensures purity and potency, with every batch tested for heavy metals, harmful additives, and label claim accuracy to meet the highest standards.
