Women's Health & Vitality
She thought exhaustion
was just part of getting older.
She was half right.
The science behind why millions of women over 40 feel drained, foggy, and cold — and the one compound their bodies quietly stop making.
Karen had always been the energetic one. At 47, she was still the first one up in the house, the one who walked the dog before breakfast, the one her friends called when they needed someone with stamina. Then, somewhere around her mid-40s, something shifted.
The mornings got harder. The afternoon slump arrived earlier and stayed longer. She started keeping coffee by her desk just to get through the 2pm stretch. Her hands were always cold — even in summer. And the brain fog. Small words vanished mid-sentence. She'd walk into rooms and forget why.
"I just assumed it was stress," she says now. "Or getting older. Everyone says that. I'd tell my doctor and she'd nod, and nothing changed. I thought maybe this was just who I was now."
"I thought maybe this was just who I was now. I didn't realise my body was quietly running low on something it used to make automatically."
— Karen, 47, MelbourneWhat Karen didn't know — and what most doctors don't have time to explain in a 12-minute appointment — is that what she was experiencing wasn't simply stress or ageing. It was biology. Specifically, the quiet decline of a single compound her body had been producing effortlessly for decades.
The compound your body stops making in your 40s
It's called nitric oxide — and most people have never heard of it, even though it quietly governs some of the most important functions in the human body.
Nitric oxide is a natural molecule your body produces from the foods you eat. Its primary job is to signal the walls of your blood vessels to relax and widen. When blood vessels are open and flexible, blood flows freely. Oxygen reaches your muscles. Your brain gets what it needs to think clearly. Your hands and feet stay warm. Your energy stays stable.
What the research shows
Nitric oxide production declines significantly with age. In women, this decline is accelerated by falling estrogen levels, since estrogen directly stimulates the enzyme that produces nitric oxide in blood vessel walls.
The result: blood vessels gradually lose their ability to stay flexible and open. Circulation slows. Tissues — including the brain — receive less oxygen. And a constellation of familiar symptoms arrives that are routinely dismissed as "just getting older."
Here's what those symptoms actually look like:
If three or more of those sound familiar, you're not imagining it. And it's not your fault. It's your circulation — and the compound that governs it.
Why beetroot is the most overlooked answer in women's health
Beetroot has been studied seriously as a cardiovascular supplement for over a decade. Elite athletes have been using it quietly since the early 2010s. But in recent years, researchers have turned their attention to a different population — postmenopausal women — and the findings are striking.
Beetroot is one of the richest natural sources of dietary nitrates. When you consume those nitrates, your body converts them into nitric oxide via a completely separate pathway from the one that relies on estrogen. This matters enormously for women over 40, because it means beetroot can help support nitric oxide levels naturally — without hormones, stimulants, or synthetic compounds.
How it works — the pathway
Beetroot supports nitric oxide through a hormone-independent pathway. Here's what happens:
01
You take one tablet
Organic beetroot's natural nitrates enter your digestive system and are absorbed into the bloodstream.
02
Conversion to nitric oxide
Nitrates are converted via the nitrate-nitrite-nitric oxide pathway — a well-established biological process.
03
Blood vessels relax and open
Nitric oxide signals blood vessel walls to widen. More blood flows. More oxygen reaches muscles, extremities, and the brain.*
04
You feel the difference
Steadier energy. Warmer hands. Clearer thinking. Results build with consistent daily use over weeks.*
A 2025 systematic review and meta-analysis of ten clinical trials specifically in postmenopausal women found that beetroot supplementation supported cardiovascular recovery after exercise and helped counteract age-related declines in vascular function — describing it as an "appealing adjunct to preventive health strategies" for this population.* A separate randomised controlled trial found meaningful improvements in cardiovascular response and heart rate recovery in postmenopausal women after beetroot supplementation.* A 2024 double-blind clinical trial also found that a beetroot-based supplement improved memory capacity and frontal cognitive function — consistent with improved blood flow to the brain.*
What women are actually experiencing
"I started this before my morning walk and the difference is real. My legs feel lighter and I don't get winded as easily. I've been walking longer without even noticing. That says everything."

"I used to hit a wall around 2pm every day. I'd reach for coffee just to function. After a couple of weeks taking Tavora, I actually feel steady energy through the afternoon — and my head feels clearer too. Simple change, real difference."

"I've dealt with heavy, tired-feeling legs for years. After about a month, walking and standing feel easier. A gentle improvement — but a meaningful one. I won't go without it now."

Not all beetroot supplements are equal
Here's something most beetroot brands don't highlight: the active compound driving the benefits isn't simply "beetroot powder" — it's the natural nitrate content within the beetroot. Most products list their dosage in milligrams of powder and leave the actual nitrate delivery completely undisclosed. A 2023 analysis found most commercial beetroot supplements delivered significantly less nitrate than fresh beetroot — meaning many products may fall short of clinically relevant doses.
Tavora Organic BeetRoot is a concentrated 2,040mg organic beetroot tablet — USDA certified, non-GMO, and free from caffeine, sugar, and artificial additives. No powder to mix. No juice to refrigerate. No chew that coats your teeth. Just one tablet a day, with water, whenever suits you.
The women who respond best tend to be in their 40s, 50s, and 60s — already looking after themselves, but noticing that their energy, clarity, and physical ease have quietly shifted in recent years. This isn't a dramatic intervention. It's a daily support that works with what your body already knows how to do.
"My mornings feel different now. I feel clearer during long work hours. I didn't expect that benefit — I started for energy and got it, but the mental clarity was the real surprise."
— Daniel K., 37, Toronto — ✔ Verified BuyerAn honest timeline
Beetroot isn't a stimulant. It doesn't produce an immediate jolt — it works gradually as nitrate levels build in your system over days and weeks. Here's what most women report:
Typical experience over time
Days 1–7: Some women notice slightly warmer extremities and a modest lift in energy. Others notice nothing yet. Both are normal — the pathway takes time to establish.*
Weeks 2–3: Most women begin to notice the difference. Energy feels steadier across the day. The 2pm slump becomes less reliable. Morning walks feel a little easier.*
Month 2 onwards: The clearest benefits emerge with consistent daily use. Better stamina, improved mental clarity, warmer circulation, and less reliance on caffeine are the outcomes most commonly reported by women in this age group.*
As with any daily supplement, consistency is the mechanism. Daily use — not occasional use — is where the results build.
Back to Karen
Karen started taking Tavora six weeks after a friend — also in her late 40s — mentioned she'd been trying it for her afternoon energy slumps. Karen was skeptical. She'd tried things before.
"The first week I didn't notice much," she says. "Then around week two or three, I realised I hadn't reached for an afternoon coffee in a few days. I was still going at 4pm. My hands were warmer. The fog was lighter." She pauses. "I know that sounds small. But after years of feeling like I was running at half capacity, small felt enormous."
She's been taking it daily for four months. She's not a different person. She's back to being herself.
