The Formula Is Not an Accident
Every supplement on the market makes promises. Most of them have no idea what is actually happening inside your body when your cycle hits.
PhazeFuel was built differently. Eight ingredients. Each one chosen because the science said so — not because it looked good on a label. Here is exactly what is in the formula, what it does, and why it is there.
1. Magnesium Glycinate — 300mg
What it does
Magnesium is a smooth muscle relaxant. That matters because menstrual cramps are, at their core, uterine muscle contractions — driven by prostaglandins that trigger the uterus to squeeze. Magnesium helps regulate that process, reducing the severity of those contractions.
Why the glycinate form
Not all magnesium is equal. The glycinate chelate form binds magnesium to the amino acid glycine, making it significantly more bioavailable and dramatically easier on the stomach than common forms like magnesium oxide. You absorb more of it, and it does not wreck your digestion.
What the research shows
A 2022 study published in BMC Women's Health found that magnesium supplementation helped support relief from primary dysmenorrhea symptoms. Research published in PMC comparing magnesium and oral contraceptives in dysmenorrhea treatment confirmed that magnesium supports measurable improvements in menstrual pain scores. A 2025 clinical trial of 150 women found that 250mg of magnesium daily provided significant support for PMS symptoms and cramping.*

2. Ginger Extract — 1,000mg
What it does
Ginger inhibits prostaglandin synthesis — the same mechanism as NSAIDs like ibuprofen. Prostaglandins are the inflammatory compounds responsible for uterine cramping. Less prostaglandin activity means less pain signaling.
Why the extract form
Standardized ginger extract delivers consistent concentrations of the active compounds (gingerols and shogaols) that drive the anti-inflammatory effect. Raw ginger root cannot guarantee that consistency.
What the research shows
A 2009 randomized controlled trial by Ozgoli et al., published in the Journal of Alternative and Complementary Medicine, compared ginger directly to ibuprofen and mefenamic acid for primary dysmenorrhea pain relief. Ginger performed comparably to both drugs at reducing pain severity. A systematic review and meta-analysis published in PMC (PMC4871956) confirmed oral ginger's efficacy for dysmenorrhea across multiple trials.*

3. Curcumin — 400-500mg (Water-Dispersible)
What it does
Curcumin is the active compound in turmeric. It works as a potent anti-inflammatory by inhibiting COX-2 enzymes and modulating prostaglandin production — the same inflammatory pathway responsible for menstrual cramps. When taken alongside ginger, the two compounds target the same pathway from complementary angles, creating a synergistic anti-inflammatory effect.
Why the water-dispersible form
Standard curcumin has notoriously poor bioavailability — your body absorbs very little of it. The water-dispersible form dramatically improves how much actually reaches your bloodstream. (And see Black Pepper below for the other half of this story.)
What the research shows
A systematic review published in PMC (2024) confirmed that curcumin's anti-inflammatory properties make it a candidate for modulating the heightened inflammatory responses seen in dysmenorrhea. Research published in the Journal of Pharmaceutical Health Care and Sciences (2025) found curcumin inhibits COX-2 enzyme activity and decreases prostaglandin synthesis — the core mechanism in menstrual pain.* A 2024 systematic review in Sage Journals confirmed curcumin's ability to modulate prostaglandin production and activity.

4. Iron Bisglycinate — 18mg
What it does
Every menstrual cycle, your body loses iron. For active women — athletes who are already under higher physiological demand — this is not a footnote. It is a performance issue. Iron is required for oxygen transport via hemoglobin. Let it slip, and your energy, endurance, and cognitive function follow.
18mg is the established daily value for women of reproductive age (National Institutes of Health).
Why the bisglycinate form
Iron bisglycinate is a chelated form — iron bound to two glycine amino acids. This structure protects the iron from inhibitors in food and improves absorption while dramatically reducing the GI side effects (nausea, constipation, stomach pain) associated with common iron supplements like ferrous sulfate. A randomized double-blind crossover trial published in PubMed (PMID 1799918) directly compared bisglycinate to ferrous sulfate and found significantly better tolerability.*
What the research shows
A 2023 systematic review and meta-analysis published in PMC (PMC10331582) confirmed that ferrous bisglycinate supplementation effectively raises hemoglobin and ferritin levels in adults. The same review noted that conventional iron salts cause frequent GI adverse events at standard doses — a problem bisglycinate is specifically designed to solve.*

5. Vitamin B6 (P-5-P) — 25mg
What it does
Vitamin B6 is a cofactor in over 100 enzymatic reactions, including the production of neurotransmitters like serotonin and dopamine. During your luteal phase — the two weeks before your period — hormonal fluctuations affect neurotransmitter balance. That is where the mood instability, irritability, and fatigue come from. B6 supports the metabolic pathways that help maintain that balance.
Why the P-5-P form
Pyridoxal-5-phosphate (P-5-P) is the active, bioavailable form of B6. Most supplements use pyridoxine HCl, which the body must convert to P-5-P. We skip that conversion step. You get the active form directly.
What the research shows
A systematic review published in BMJ and available via PMC (PMC27878) evaluated randomized controlled trials on vitamin B6 for premenstrual syndrome and found evidence supporting its role in managing emotional symptoms. A separate randomized crossover trial (PMID 2558186) of 32 women found a statistically significant beneficial effect of pyridoxine on emotional symptoms including depression, irritability, and tiredness during the premenstrual phase.*

6. Nettle Leaf — 300mg
What it does
Nettle leaf (Urtica dioica) has been used for centuries to support heavy menstrual flow. It is naturally rich in iron, potassium, and other minerals. It also carries anti-inflammatory properties that complement the formula's core anti-inflammatory stack.
Why it is in the formula
Nettle adds nutritional density to the formula's iron replenishment strategy — working alongside iron bisglycinate rather than replacing it. Its traditional use for heavy flow support is backed by its mineral composition and documented anti-inflammatory activity.
What the research shows
A comprehensive review published in PMC (PMC9253158) on the nutritional and pharmacological importance of Urtica dioica confirmed that nettle leaf contains significant concentrations of iron, zinc, potassium, and other minerals, accounting for approximately 20% of the plant's dry mass. The same review documented its anti-inflammatory properties.* Nettle's use for heavy menstrual flow and anemia support is well established in traditional botanical medicine literature.

7. Vitamin C (Ascorbic Acid) — 100mg
What it does
Vitamin C does one specific job in this formula: it makes the iron work better. Ascorbic acid converts ferric iron (Fe³⁺) to the more absorbable ferrous form (Fe²⁺), and it inhibits the compounds that block iron absorption. The result is a meaningful increase in how much iron actually gets absorbed.
What the research shows
The role of ascorbic acid in enhancing non-heme iron absorption is one of the most well-documented interactions in nutritional science. Research published in PubMed (PMID 2507689) established that the key role of ascorbic acid for the absorption of dietary non-heme iron is broadly accepted in the scientific literature. A separate study (PMID 6940487) demonstrated that iron absorption from meals increases in parallel with ascorbic acid intake. Multiple sources confirm the enhancement effect can be substantial when both nutrients are consumed together.*

8. Black Pepper Extract — 10mg
What it does
Black pepper extract (standardized to piperine) does one critical thing: it makes curcumin actually work. Curcumin on its own is rapidly metabolized in the liver and intestinal wall before it reaches systemic circulation. Piperine inhibits that metabolism, allowing curcumin to stay in the bloodstream long enough to do its job.
What the research shows
A landmark human clinical study by Shoba et al., published in Planta Medica in 1998, demonstrated that piperine enhanced the bioavailability of curcumin by 2,000% in human volunteers, with no adverse effects at the doses tested. This finding has been replicated and cited extensively in the literature.* A randomized controlled trial published in PMC (PMC5358025) on curcumin and piperine for exercise-induced muscle damage cited the same 2,000% enhancement figure in human subjects.

The Stack in Context
These eight ingredients do not work in isolation. The formula is engineered as a system:
- Anti-inflammatory core: Ginger + Curcumin + Magnesium, each targeting prostaglandin activity and smooth muscle tension from different angles
- Iron recovery stack: Iron Bisglycinate + Vitamin C + Nettle Leaf, maximizing iron replenishment with gentle, high-absorption delivery
- Bioavailability optimizers: Black Pepper (for Curcumin) and the Glycinate chelation form (for both Magnesium and Iron) ensure what you take actually gets absorbed
- Hormonal support: Vitamin B6 (P-5-P) targeting the neurotransmitter pathways affected by your luteal phase
No filler. No proprietary blends hiding underdosed ingredients. No ingredients that are not in the product just to look good on the label.
This is the formula. Now you know why.
