Waiting it out
Cost: free · Works: no
Still the most common advice, usually unspoken. Pain that regularly takes out your day isn't something to tough out, and it isn't something to file under normal either.
If it makes you miss work, if it's getting worse year over year, or if it turns up outside your period, get it looked at. Endometriosis still takes years to diagnose in most women, largely because they were told this was normal.

Magnesium
Cost: $10 to $25 a month · Works: a little, slowly
Magnesium relaxes muscle and plenty of women are running low, so it's worth taking anyway. But it works in the background over weeks. It won't do much for you on day one.
Watch the form. Magnesium oxide is the cheap one in most bottles, barely absorbs, and mostly affects your digestion. Glycinate or citrate are worth the extra couple of dollars.

Worth taking. Won't rescue you.
Heat, specifically continuous heat
Cost: $15 to $40 once · Works: yes, immediately
Heat is better than its reputation. Held against your lower abdomen continuously, it brings blood flow to the area and relaxes the muscle that's spasming. Studies putting continuous low-level heat wraps up against oral painkillers have found them roughly comparable for period pain.
The problem is practical. A heating pad keeps you near an outlet and a microwave pack has gone cold by the time you've found your keys. Stick-on heat patches solve that. Keep some in your bag.

The best thing on this list you don't swallow. Use it alongside whatever else you're doing.
Ibuprofen and naproxen
Cost: pennies · Works: yes, with caveats
Credit where it's due. Ibuprofen works, and it works on the right thing. NSAIDs block prostaglandin production, which is what sets cramp intensity in the first place. Take it before the pain peaks and most women get real relief.
Two reasons it isn't first. Regular use is rough on your stomach lining, and it does nothing about why some cycles are worse than others. If you're quietly increasing your dose every month, that's information.

Works. Fine now and then. Not something to lean on twelve times a year for a decade.
A herbal antispasmodic tincture
Cost: $49 a month · Works: 15 to 30 minutes
This is the one that hits both mechanisms at once without the stomach cost.
Cramp bark does the heavy lifting. Its compounds relax smooth muscle and have a particular affinity for the uterus. Ginger handles the inflammatory half. Research has put it up against ibuprofen for period pain and found it holds its own, and it settles the nausea that often rides along with a bad cramp day. Wild yam adds antispasmodic and anti-inflammatory action in uterine tissue. Chamomile takes down the tension that makes pain feel bigger than it is.
Format does more work here than people expect. A capsule has to dissolve in your stomach before anything reaches your blood, which takes 45 to 90 minutes. A tincture goes in under the tongue and starts working in 15 to 30. When you're doubled over, that gap is the whole point.

The most complete option here, and the only one you can start two days early to make the whole period easier.
