Most vitamins are fine together, but a few minerals crowd each other out. Here's which combinations to separate, why, and how long to wait.

The best time to take vitamin D is with the meal of the day that contains the most fat — that single habit raises absorption measurably, while morning-versus-evening barely moves the needle. Here is what the trial evidence actually says about timing, daily versus weekly versus monthly dosing, magnesium and K2, testing, and the real risk of megadosing.

Vitamin K2 is sold on the "calcium paradox" story: that it steers calcium into your bones and away from your arteries. The biochemistry is sound. The trial evidence for fractures and heart events is not there yet — and anyone on warfarin needs to be careful.

When a bottle just says "vitamin D," it usually means D3. Here's the plain-language difference between D2 and D3, typical amounts for adults, and why testing your level beats guessing.

Magnesium and zinc are both sold as sleep helpers. We compare their mechanisms, the (weak) evidence and who each might suit — plus why neither is a cure.

In your 50s, menopause typically arrives, hot flashes and vaginal changes often peak, bone loss speeds up, and heart risk rises. A calm, body-system-by-system guide to what's normal, what helps, and which routine screenings matter most now.

A woman's-health guide to your 40s: cycle changes and early perimenopause, declining fertility, shifting metabolism, and the blood-pressure, cholesterol, and diabetes screenings that start to matter now.

In your 60s, most hot flashes ease, but genitourinary symptoms often linger and bone, heart, brain, and muscle health take center stage. A practical, evidence-based guide to what to expect and how to stay strong.

In your seventies the threats change shape: fractures, falls, blood pressure and untreated hearing loss matter more than almost anything else — and most of them are modifiable. A decade guide with a screening table, honest evidence grades, and clear reasons to call your clinician.

Red clover is widely marketed for hot flashes, but does it work? We weigh the trial and review evidence, label its strength plainly, and flag the safety and interaction points that matter.

Evening primrose oil is one of the most heavily marketed menopause supplements — and one of the least supported. The trials are small, short and mixed, hot-flush studies carry a huge placebo response, and no major menopause society recommends it for vasomotor symptoms. Here is the honest read, plus the treatments that do have evidence.

Black cohosh is one of the most popular herbal supplements for menopause, but does it work? We weigh the Cochrane review, NCCIH, and The Menopause Society, label the strength of the evidence honestly, and cover the rare liver-safety reports.

How the main thyroid medications compare: levothyroxine (T4), liothyronine (T3), combination T4/T3, and desiccated (natural) extract — what each does, who it may suit, and how treatment is monitored.

From systemic HRT to fezolinetant, SSRIs, gabapentin, and CBT: how the main menopause symptom treatments compare, who they tend to suit, and what to weigh with your clinician.

A plain-language matrix of the main osteoporosis drug classes — how each works, who it may suit, how it is given, and the key cautions — so you can have a more informed conversation with your clinician.

Persistent tiredness in women has many possible causes, from poor sleep and perimenopause to iron deficiency, thyroid problems, and sleep apnea. Here are the red flags to act on and the simple blood tests a clinician can order.

Night sweats that soak your bedding have many possible explanations. Here are the causes to consider, the red flags to act on first, and the simple checks a clinician can do.

Weight that rises without a clear change in eating or exercise has many possible explanations, from perimenopause and an underactive thyroid to medications and fluid retention. Here is how to tell what is worth checking, and when the change needs a doctor sooner rather than later.
