Glyco Barrier Motherwort: The One Ingredient With No Source to Cite

What is Glyco Barrier motherwort?
Glyco Barrier motherwort is listed as Motherwort Extract on the Supplement Facts panel. The plant is Leonurus cardiaca. The label does not print which part of the plant is used. It is the fourth of the six names under the 121 mg blend.
Motherwort is a traditional European herb. It is used in folk practice for palpitations and anxiety. Its marketing role in this product is small. The brand's artwork names it, along with hawthorn, grape seed and gotu kola.
Why does this site cite no source for Glyco Barrier motherwort?
Every other ingredient on this site carries a citation. Motherwort does not, and that is not an oversight. We searched the three references the site uses: the NIH Office of Dietary Supplements, NCCIH and the About Herbs database at Memorial Sloan Kettering. None of them holds a monograph on it.
We could have linked a supplement shop, a content farm or a journal abstract we are not qualified to appraise. We chose not to. A visible blank is more honest than a link that looks authoritative and is not. The same rule applies to every ingredient page here: no citation beats a weak one.
What does the label tell you about Glyco Barrier motherwort?
Very little, and it is worth seeing the whole picture in one place.
| Question | Answer |
|---|---|
| Is the amount published? | No. Only the 121 mg total for six plants |
| Is the plant part printed? | No |
| Is an extract ratio published? | No |
| Is there a research dose? | No reliable range could be sourced |
| Is there a reference page at NIH, NCCIH or Memorial Sloan Kettering? | None found |
| Where is it in the blend? | Fourth of six, so not the largest or the smallest share |
Because it is fourth, the descending-weight rule tells you it is smaller than gotu kola, hawthorn and horse chestnut, and larger than butcher's broom and grape seed. That is all the rule gives.
Is Glyco Barrier motherwort safe in pregnancy?
Motherwort is traditionally avoided in pregnancy. This site does not claim to know the amount in the bottle, so it cannot say that a given dose is small enough to ignore. A cautious reading treats the warning as applying.
Separately, Memorial Sloan Kettering's hawthorn page lists pregnancy under Do Not Take, and hawthorn is in the same blend. For pregnancy or breastfeeding, the sensible step is to ask your doctor first. The safety page gives the wider list.
How does Glyco Barrier motherwort fit with heart medicines?
Motherwort is generally described as having sedative and cardiac activity. That puts it in the conversation with a clinician, alongside anything you take for your heart. Hawthorn, in the same formula, also has heart-medicine flags.
No citable safety file means no quantified safety information. That is not the same as an absence of risk. Absence of a reported harm in a source that does not exist is not evidence of safety. Read the six plant names out to your pharmacist and let them decide.
The label's own line says to check with your doctor before using the product if you are using medication or have any medical condition. On this formula that line is doing real work.
What should you ask about Glyco Barrier motherwort before you order?
You can phone the order desk on +1 (302) 200-3480 with three questions. Which part of the plant is in the extract? What is the extract ratio? How much of the 121 mg is motherwort? You may not get an answer, because the details are not published. The attempt is still worth making.
If you do hear back, tell us through the site email so we can correct the page. In the meantime, our post GlycoBarrier side effects: is it safe? sets out the other cautions, and the ingredients page shows the full list.

Our view
Our view is that motherwort is the clearest example of why this site prints the word not published. We cannot tell you the amount, the part or the research. We can tell you the traditional pregnancy caution and the advice to ask a clinician.
A blank is a fact too. It tells you where your questions should go: to the order desk and to your own doctor.

Before any order, talk to your doctor if you take a heart medicine, are pregnant or are breastfeeding.
