FROM THE FOUNDER

How a Decade of Back Pain Led Me to Build This

I'm Marcus Reid. A couple of years ago, I was lying on my kitchen floor at 2am because it was the only position that didn't hurt.

I was 44. Eighteen years running my own construction business, and chronic back pain had gotten bad enough that I couldn't lift a 2x4 without wincing. It started affecting how much work I could take on.

I tried everything. PT, chiropractic, an expensive round of injections that wore off in under three weeks, medication that left me foggy, three turmeric brands off Amazon. Two years. Thousands of dollars. My wife noticed how much it was wearing on me.

Then I started digging into the research on bioavailability. Most of what you swallow in a capsule never actually reaches your bloodstream — a huge amount of it is broken down before it can do anything.

I'd been trying to put out a fire with a squirt gun.

So I built Lumbar IV. Six botanicals. Three inflammation pathways. Liquid form, designed for direct absorption. And I priced it so nobody has to choose between their mortgage and trying something that might actually help.

A couple of months later, I put my socks on without wincing. A couple of months after that, I was back on a job site full-time.

What Sets Lumbar IV Apart?

Most botanical supplements sound the same — but there are real differences in how well your body can actually use what you take.

Designed for Better Absorption

A significant amount of what's in a standard capsule is lost before it reaches your bloodstream. Lumbar IV absorbs sublingually — bypassing your stomach entirely.

Six Botanicals, Three Inflammation Pathways

A healthy inflammation response involves multiple pathways — 5-LOX, NF-κB, and COX. Lumbar IV is formulated to support all three.

Clinically-Studied Botanicals at Meaningful Doses

Every botanical at the dose the clinical research backs. No proprietary blends. No vague labels. Every ingredient, fully disclosed.

How to Take Lumbar IV

Designed to integrate seamlessly into your daily routine. Sublingual delivery means no swallowing capsules, no fighting digestion, no guesswork.

Follow Label Directions for Dosage

Hold Under the Tongue Briefly

Morning, Empty Stomach

Daily for 60 to 90 Days

365-Day Money-Back Guarantee

Don't feel the difference within a full year? Send back the empties for a full refund. No restocking fees. No questions asked.

Have Questions?
We Have Answers.

How is this different from the turmeric capsules I've already tried?

The ingredient is the same. The delivery isn't. Standard capsule curcumin is known for very low bioavailability — much of it is broken down before it ever reaches your bloodstream. Lumbar IV is a dual-extracted liquid held under the tongue, so compounds absorb directly through the mucous membranes, bypassing that digestive breakdown. Plus, capsule turmeric is usually a single ingredient — Lumbar IV combines six clinically-studied botanicals targeting three different inflammation pathways simultaneously.

Why isn't this more well-known?

Botanical pharmacology isn't a major focus in standard medical training, which centers on pharmaceutical and surgical approaches. That's not a knock on doctors — it's just how medical education is structured. Always loop your doctor in on anything you add to your routine.

How long until I notice a difference?

Honest answer: most people don't notice anything in the first week. First hints show up around 2 to 3 weeks. Best results come at 90 days+. Consistent daily use over 60 to 90 days is what the research is based on. Anyone promising 3-day results is selling something different than what we're selling.

What's the difference between the three phases?

The First Phase is your starter month — a single bottle, 30 days. The Recognition Phase is the 90-day window where most people see measurable changes — that's why it's the most chosen tier. The Identity Phase is the six-month full course at the lowest per-day cost. All three include the same product. The difference is duration of commitment and per-bottle pricing.

How does the subscription pricing work?

Subscribe and save 20% on every order. Your price is locked — if we raise prices later, your rate stays the same as long as your subscription is active. The First Phase is $40/month, the Recognition Phase is $100.80 every 90 days, and the Identity Phase is $168 every 180 days. Cancel anytime by emailing support. No phone calls, no hoops, no questions asked.

Can I take it with gabapentin, NSAIDs, or blood thinners?

Always check with your doctor or pharmacist before combining supplements with prescription medications. White Willow Bark and Meadowsweet contain natural salicylates similar to aspirin, which means they may interact with blood thinners (warfarin, etc.) and other anti-inflammatory drugs. We're not a substitute for medical advice. If you're on any prescribed medication, bring our ingredient list to your next appointment.

Does it contain alcohol?

No. Lumbar IV is completely alcohol-free. Most herbal tinctures use 30 to 40% cane alcohol as the extraction solvent — it's cheaper and extends shelf life. We use a dual-extraction process with distilled water and organic vegetable glycerin instead. You get the same compounds, none of the alcohol.

How do I take Lumbar IV?

Lumbar IV is taken sublingually — place the recommended dose under your tongue and hold it there before swallowing. For exact serving size and frequency, always follow the directions printed on your product label. If you have any health conditions or take other medications, check with your doctor or pharmacist before starting any new supplement.

What if it doesn't work for me?

Send back the empty bottles within 365 days for a full refund. No questions, no restocking fees. Email us and we'll process it.
