Genuinely felt the difference.
I'd been on my medication for a year before I tried Cofactor. The energy dips I'd been chalking up to the meds started lifting after about three weeks.

Description
Daily Liquid Cofactors for Hormone Therapy
Protocol-specific nutrition designed for people on hormone replacement therapy (HRT), including menopause and perimenopause protocols.
Hormonal changes during menopause accelerate bone loss, affect skin integrity, and shift mineral needs. Cofactor HRT provides targeted nutritional support for your hormone therapy protocol.
Formulated For
- Mineral Cofactors — Calcium, vitamin D, and essential minerals for hormonal balance
- Bone + Muscle Support — Targeted nutrition to maintain bone density and muscle strength during hormonal transitions
- Skin + Cellular Health — Antioxidants and nutrients that support skin elasticity and cellular renewal
Why Cofactor HRT?
Menopause and hormone therapy create specific nutritional demands. Cofactor HRT is formulated around the evidence — not generic wellness claims.
This product is a dietary supplement and is not intended to diagnose, treat, cure, or prevent any disease. Consult your healthcare provider before use.

Inside the formula
Every ingredient earns its place.
No filler, no kitchen-sink labels. Each cofactor is dosed to address a specific, documented gap your protocol creates — at amounts your body can actually use.
-
Vitamin B12 (methylcobalamin)1,000 mcg
The active, bioavailable form — supports energy metabolism and nerve health that this protocol can quietly erode.
-
Magnesium glycinate200 mg
A gentle, well-absorbed form that supports muscle, sleep, and blood-sugar regulation without the GI upset of cheaper salts.
-
Vitamin D3 + K22,000 IU / 90 mcg
Paired so calcium goes to bone, not arteries — foundational support that's hard to get from diet alone.
-
Electrolyte blend—
Sodium, potassium, and chloride to offset the fluid and mineral shifts common in the first months of treatment.
Every batch is third-party tested for purity and potency.
How it works
Designed for your protocol — not a generic multivitamin.
Most supplements weren't formulated with your medication in mind. Cofactor is built to fill the specific nutritional gaps your protocol creates.
-
Your medication does its job
Modern protocols change how your body absorbs, metabolizes, and stores key micronutrients.
-
Specific nutrients get depleted
Documented depletions vary by drug — vitamins, minerals, and metabolic cofactors your body still needs every day.
-
Cofactor fills the gap
Liquid daily formulation matched to your exact protocol. Easier to absorb, easier to take, designed for the long haul.
Why people stay
Trusted by thousands on their protocol.
People who take a daily medication shouldn't have to guess about nutrition. Cofactor takes the guesswork out — and they keep coming back.

Questions, answered
Frequently asked
Can I take this alongside my medication?
Cofactor is formulated to complement your protocol, not interfere with it. Ingredients and dosages are chosen to address the specific micronutrient depletions documented for users of this medication. As with any new supplement, confirm with your healthcare provider — especially if you're on multiple prescriptions.
When during the day should I take it?
One full dropper, once a day. Most people take it in the morning with water or their first meal. If you have a sensitive stomach, take it with food.
How is this different from a regular multivitamin?
Generic multivitamins are formulated for a generic person — not someone whose body chemistry has been altered by a daily medication. Cofactor is built around the documented nutrient gaps your specific protocol creates, at clinically meaningful doses.
When will I notice a difference?
Most customers report changes in energy, digestion, or mood within 2–4 weeks. Full micronutrient repletion takes longer — typically 8–12 weeks of daily use.
What if I switch medications?
Cofactor is protocol-specific. If you move from one medication to another (for example, GLP-1 to metformin), you can switch your subscription to the matching Cofactor product at any time from your account.
Can I pause or cancel?
Yes — pause, skip, or cancel anytime from your account. No phone calls, no pressure.
What customers say
Real results from real protocols.
Finally — a supplement that gets it.
Most multivitamins are a shotgun approach. Cofactor was built for my exact protocol, and it shows in the formula and how I feel.
Easy to take, easy to remember.
Dropper format is way easier than my old pile of pills. Subscription auto-renews so I never run out.
