Your questions, answered

Once a day, straight after a meal. The raft needs food in your stomach to form. If your reflux is worst at night, take it after dinner.

Pour one sachet into 100 to 200 ml of water, cold or warm. Froth it for 20 seconds with your frother and drink. No frother? Shake it in a sealed bottle.

Gently sweet, like vanilla custard. It's thicker and silkier than most drinks; that's the seaweed. Add more water if you like it thinner. No mint, citrus or ginger, the flavours that set reflux off.

From the very first sip. It goes down cool and silky, and you feel your throat start to calm. The raft gets to work after your meal. From week one, flare-ups get fewer and milder. The deeper repair happens over 8+ weeks of taking it every day.

One box is 30 sachets, so it lasts a month. For the full 8 weeks, start with two or three. 2 boxes are $89 and 3 boxes are $119.

In three steps, starting the moment you sip.

First, your throat. Slippery elm and aloe coat it on the way down, so the burn calms straight away.

Then your stomach. Seaweed alginate forms a soft raft on top of your meal. When the door at the top of your stomach opens, the raft goes up first, not the acid.

Then, over the weeks, your lining. DGL licorice and L-glutamine help it repair while the raft keeps the burn off it.

Alginate comes from brown seaweed. When it meets the acid in your stomach after a meal, it turns into a soft gel. Potassium bicarbonate makes that gel float, and calcium carbonate firms it up, so it sits on top of your stomach contents. Yasu has 1,000 mg of alginate and 200 mg of potassium bicarbonate per sachet, the same raft chemistry used in pharmacy alginate liquids.

Studies on alginate rafts at this strength show the raft sitting on top of the stomach for up to about 4 hours after a meal. That's why you take Yasu straight after eating.

Each one does one job. Slippery elm soothes but doesn't block. Alginate blocks but doesn't coat your throat. DGL supports your lining but works slowly. Yasu puts them together in one drink, at doses that work, with every dose on the label.

No. Rebound happens when something has switched your acid off for a long time, and your stomach overcorrects when you stop. Yasu doesn't switch your acid off, so there's nothing to bounce back from. And if you and your doctor decide to step your PPI down, the raft is there to catch what comes up.

Yes. Take them 2 hours apart. The simplest way to start is to take both, so the raft is already in place. Then, if you and your doctor decide to step your PPI down, the raft is still there to catch what comes up.

Not on your own. Stopping a PPI suddenly can bring the burn back harder. If you want to come off it, talk to your doctor about stepping down slowly. Yasu doesn't replace your medication. It's there alongside it.

Take Yasu 2 hours apart from any medication, because alginate and slippery elm can slow how other medicines are absorbed. If you have high blood pressure, take heart medication or have a medical condition, check with your doctor first.

Check with your doctor or midwife first, and bring the ingredient list with you.
