Magnesium Aid™ by Bare Willow – Calms Knee Pain Where It Starts and Helps Your Cartilage Repair

Magnesium Aid™ is designed to calm the hidden cause of knee pain — the inflamed lining that wraps around your knee joint, the part an X-ray can't show — while helping your cartilage repair and the tight muscles around your knee let go.

Just a thin layer before bed and before you get up goes straight to where it hurts — naturally supporting easier first steps, calmer knees and steadier stairs.

  • Calms the inflamed lining that makes your knee ache, swell and feel warm
  • Helps your cartilage repair itself with magnesium + niacinamide
  • Releases the tight muscles so your knee feels steady on the stairs
  • Cools within 15 minutes, so your first steps hurt less

How Does It Work?

Your cartilage has no nerves, so it isn't what hurts. The pain comes from the lining that wraps around your knee joint. An X-ray only shows bone, so it can't show the lining. That's why it's called Hidden Lining Inflammation.

Calm: after 40, some cells in your knee wear out but don't die. Scientists call them zombie cells, and they keep the lining inflamed. Boswellia calms that inflammation, arnica eases the swelling and soreness, and B6 calms another source of inflammation.

Repair: your cartilage cells repair it every day, using cellular energy they make from NAD+. After 40, you make less of it. Niacinamide is what your body uses to make NAD+, and magnesium is what turns it into cellular energy. Vitamin E helps protect your healthy cartilage cells.

Release: when your knee is sore, the muscles around it tighten up and get too tired to hold it steady. Magnesium helps them let go, and arnica and camphor bring blood flow to them.

What Can Magnesium Aid™ Help With?

🪜 Stairs: less grinding and less holding the railing, as your muscles hold your knee steady again.

🌅 Stiff First Steps: your knee loosens up faster in the morning.

🔥 Swelling & Warmth By Evening: as the lining calms down, the puffiness and warmth go down.

🪑 Getting Out Of A Chair: stand up without pushing off with both arms.

🌱 Kneeling: get down on the floor or into the garden, and back up again.

😴 Sleep: fewer nights woken up by a deep ache at 3 AM.

When Will I See Results?

📅 In The First 15 Minutes: menthol, camphor and peppermint oil cool your knee, so your first steps and the stairs hurt less.

📆 After 2–4 Weeks Of Daily Use: the swelling and warmth by evening go down, and there's less grinding on the stairs.

📈 With Ongoing Use: by months 3–6, your knee holds steady and you take the stairs without the railing.

How Long Until I Get It?

Orders are delivered in 7–10 business days, depending on where you live. You'll get a tracking number by email as soon as your order ships.

Your refill ships every 30 days so you never run out, and you can stop or cancel anytime.

Who Can Use It?

Magnesium Aid™ is made for adults over 40 with knee pain. It's especially helpful for:

Anyone who holds the railing or takes the stairs one step at a time
People with stiff, painful first steps every morning
Anyone told it's "bone on bone" or "just wear and tear"
Those who've tried shots, pills, gels and braces that didn't last

It's rubbed on, so it skips your stomach. If you have concerns about your specific condition, check with your doctor first.

Results or Full Refund Guarantee

Your order today is protected by our 90-day money-back guarantee.

Modern Knee Care May Be Falling Short

Most knee products only treat the surface. Cooling gels like Bengay, Icy Hot, Biofreeze and Voltaren cool your skin or calm the pain for a few hours. None of them have niacinamide, so nothing changes underneath.

Magnesium creams, sprays and pills are magnesium alone, and magnesium can't make cellular energy without NAD+. Epsom salt soaks are magnesium too, which is why your knee feels looser in the bath and stiff again by morning. Joint supplements like glucosamine, collagen and turmeric are swallowed, and your cartilage has no blood supply, so very little ever reaches it.

Knee massagers, TENS machines and red light therapy feel good while they're on, but the lining is still inflamed when you turn them off. Physical therapy builds stronger muscles, which is worth having, but it can't calm an inflamed lining. Braces only help while you wear them, and shots wear off in weeks or months.

None of them calms the lining, helps your cartilage repair and releases the tight muscles at the same time.

Why Your Epsom Salt Soak Helped… Then Stopped Helping

If you've ever soaked your knee in a hot Epsom salt bath, you know the feeling. It eases up for the evening. Then you wake up, and the stiffness is right back on your first steps.

There's a reason it helped at all: Epsom salt is magnesium. The warm water and the magnesium help the tight muscles around your knee let go, so your knee feels looser while you're in the bath.

And there's a reason it didn't last. Your cartilage cells repair your knee using cellular energy, and they make it from NAD+, a molecule your body makes less of after 40. Magnesium is what turns NAD+ into cellular energy, but on its own it has little NAD+ to work with. So nothing changes underneath, and the soak wears off by morning.

The missing piece was found back in the 1940s. A doctor named William Kaufman spent years giving niacinamide, a form of vitamin B3, to patients with stiff, painful joints. Your body uses niacinamide to make NAD+.

Magnesium Aid™ puts the two together in one rub-on, with boswellia and arnica for the inflamed lining. Together they are known to:

  • Calm the inflamed lining around your knee
  • Give your cartilage cells the cellular energy to repair
  • Help the tight muscles around your knee let go
  • Cool your knee within 15 minutes

So instead of a soak that wears off by morning, you rub it on right where your knee hurts, before bed and before you get up.

Is Magnesium Aid™ safe to use with my current medications?

Magnesium Aid™ works where you rub it and doesn't go through your stomach. It's always best to check with your healthcare provider before starting anything new, especially if you take medications or have existing health concerns.
