Tick every one you've felt in the last month:
Ticked 3 or more? That's not stress. That's cortisol. When oestrogen drops in midlife, your body loses its natural cortisol brake, and your stress hormone runs wild: spiking at 3am, crashing your thyroid by 2pm, draining your B-vitamins all day long. The good news? It's fixable. Keep reading.

“I look forward to it in the mornings, which is not something I ever said about a supplement.”
Sarah H.“Three months in and the afternoon slump has genuinely gone.”
Dawn M.“Taking it alongside my HRT with no issues at all.”
Priya K.“My mood has been steadier than it has in years.”
Angela T.“One scoop in the morning and that is the whole routine. Easy to stick to.”
Jen W.“I feel more like myself again. That is the best way I can put it.”
Lou B.For decades, oestrogen kept your cortisol in check. In midlife it drops, and your adrenals start dumping cortisol at exactly the wrong times. That's the 3am wake-up. The racing mind. The fuse that's gone from long to non-existent. 600mg of KSM-66® Ashwagandha, backed by 38 human clinical trials, is shown to bring elevated cortisol back down so your nervous system can finally switch off. Add active B6 and B12, which chronic stress burns straight through, and you get your calm, clear-headed self back. (Tried ashwagandha and felt nothing? You had a sprinkle. The studies used 600mg. Most brands use 250.)
High cortisol doesn't just wreck your nights. It slows your thyroid, your body's metabolic engine, and that's your 2pm crash, the bone-deep fatigue, the "your bloods are normal" that doesn't match how you feel. Your thyroid runs on iodine, which your body can't make. Balance Tonic is the only formula with organic PureSea® Scottish seaweed iodine, restarting the engine that stress shut down. Calm the cortisol. Restart the thyroid. That's what one scoop does that your pile of pills never could.

Your reset begins. Active B6 and B12 absorb fast and start replenishing what months of high cortisol have drained. Most women notice the first shift here: a little less wired, a little more steady.
The 2pm crash starts to lift. B vitamins are rebuilding your energy, and PureSea® iodine is feeding the thyroid stress has been starving. The third coffee starts to feel optional.
The cortisol window. Most of KSM-66®'s 38 clinical trials ran for 8 weeks, the point where lowered cortisol and calmer moods were measured. This is when women tell us the 3am wake-ups stop, their fuse comes back, and evenings feel like theirs again.
Fully reset. KSM-66® calming the stress response, B6 regulating hormonal activity, iodine powering your thyroid, all working together. Sleeping through. Steady energy. No more wired-but-tired. This is the milestone our 90-day promise is built on.
Your new baseline. The women in Rheal's survey stop describing symptoms and start describing themselves: "more like me than I've been in years."
Protected for the long run. Vitamin D and K2 support the bones that midlife cortisol and falling oestrogen put at risk. One scoop, 365 mornings, and cortisol that's no longer running your life.

Balance Tonic contains 600mg of KSM-66® Ashwagandha, the most clinically studied ashwagandha in the world, researched across 38 human trials and shown to reduce cortisol levels in stressed adults. Combined with active B6 and B12 and PureSea® iodine for your thyroid, it's built specifically for the way cortisol behaves in midlife.
In a healthy rhythm, cortisol drops at night and rises gently in the morning. When oestrogen falls in perimenopause and menopause, that rhythm breaks down, and cortisol can spike in the early hours, jolting you awake with a racing mind. Balance Tonic's 600mg of KSM-66® Ashwagandha is designed to calm that spike so you can sleep through.
It has a mild, berry-fruity flavour - not the earthy bitterness people expect.
Most women notice subtle changes within 1–2 weeks, especially in sleep and energy. By weeks 3–4, improvements in mood, focus, and balance are often more noticeable. The biggest benefits build over time with consistency - typically across 8–12 weeks. It’s not an overnight fix, but a gradual reset that lasts.
Mix one scoop (5g) in water, fresh juice, a smoothie, or yoghurt. Simple!
Yes - Balance Tonic Menopause is designed to support both perimenopause and menopause. It helps address common symptoms by supporting your body’s hormone activity (Vitamin B6 contributes to the regulation of hormonal activity). Many women start taking it during perimenopause, when symptoms first begin to appear.
Whilst the studies against KSM-66® Ashwagandha suggest its safety, we’re unable to give medical advice. What we can say though, is that Balance Tonic is designed to support general wellbeing and nutritional intake, but it does not replace medical treatment or hormone therapy. And if you have concerns about hormonal health, have a health condition, or take any medications - it’s always best to speak with a healthcare professional.
KSM-66® is a high-quality, full-spectrum extract of ashwagandha root - developed over 14 years and backed by 50+ clinical studies. It’s standardised to contain consistent levels of active compounds (withanolides), which are linked to supporting stress response, mood, and hormonal balance. Not all ashwagandha is the same - KSM-66® is one of the most researched and trusted forms available.
