The multivitamin made for people on omeprazole

Tired every day? Legs cramping at night?That may not be your age. It may be your omeprazole.

Your PPI turns your stomach acid down. But you need that acid to take in B12, magnesium and iron. GastroComplete uses forms that need less of it.

Yes, I want GastroComplete

Take it with your PPI, not instead of it. 3 capsules a day. One bottle lasts a month.

Why a PPI can leave you tired, foggy and full of cramps:

You wake up tired. You go to bed tired.

Your legs cramp at night. Your eyelid won’t stop twitching.

You walk into a room and forget why you went in.

Your GP runs a blood test. It comes back “normal”.

So you’re told it’s stress. Or your age. Or to eat more bananas.

If that sounds like you, it may not be your age. Here’s what nobody told you:

Step 1:

Your PPI turns your stomach acid right down…

PPI STOMACH ACID LOW NORMAL
Step 2:

…so B12, magnesium and iron stay locked in your food.

IN YOUR FOOD B12 Mg Fe Ca PASSES STRAIGHT THROUGH

Stomach acid is the key that frees these from your food. Less acid means less gets in. The longer you take a PPI, the bigger that gap can get. Eating well can’t fix that.

Fact: Omeprazole can lower your B12.

The NHS lists very low B12 as a side effect. It can cause tiredness, dizziness and muscle twitches.

1 YEAR+

The NHS says serious side effects are more likely after a year on omeprazole. Very low B12 is one of them.

Source: NHS, “Omeprazole”, side effects section: nhs.uk/medicines/omeprazole

Fact: It can lower your magnesium too.

Drug safety bodies in the US and UK have both warned about it. Low magnesium can cause cramps, shakes and a racing heart.

2011

US FDA warns that long-term PPI use may cause low magnesium. Most cases came after a year or more.

2012

UK MHRA tells doctors the same. It says to think about testing magnesium in long-term users.

Fact: A normal multivitamin may not fix it.

Many use cheap forms. Those lean on stomach acid to absorb. On a PPI, you have less of it. So more of your money goes down the loo.

Word for word from verified GastroComplete reviews.

Why I made GastroComplete.

Every week, people tell me the same story. Years on omeprazole. Always tired. Cramps at night. Blood tests that come back “normal”.

Nobody told them their PPI can drain B12 and magnesium. So I made a multivitamin built for that gap. Yes, we sell it. I made it because nobody else was fixing this.

Questions people ask

Do I stop taking my PPI?

No. GastroComplete goes alongside your PPI. It does not replace it. Never stop or change a prescription without talking to your doctor.

How many do I take?

3 capsules a day. One bottle has 90 capsules, so it lasts one month.

How soon will I notice a difference?

Everyone is different. Ronald felt more energy after three weeks. But stores that ran low over years take time to build back up. Plan on 3 to 6 months.

Why has my pee turned bright yellow?

That is vitamin B2. It is bright yellow by nature. Your body keeps what it needs and passes the rest. It is harmless.

I take other medicine, or I’m pregnant. Is it OK?

Ask your doctor or pharmacist first. GastroComplete has vitamin A and iron. Both matter in pregnancy and with some medicines.

Is it vegetarian?

Yes. It is just the nutrients in a veggie capsule. Nothing else is added.

Do you ship to my country?

We ship from the UK and the USA to most countries. That includes Ireland, Canada, Ghana, Nigeria, South Africa and the Philippines. Shipping is free on UK orders over £50 and US orders over $70.
