Molybdenum + Barium Sulfate
Barium Sulfate brand names: E-Z-HD, Readi-Cat 2, Readi-Cat 2 Smoothies, Varibar.
We found no known interaction between Molybdenum and Barium Sulfate in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.
Molybdenum and Barium Sulfate
We checked these two against our interaction database. Here is what we found.
No Known Interaction Found
We did not find a documented interaction between Barium Sulfate and Molybdenum in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.
Worth understanding: our licensed dataset holds no drug-interaction record for Molybdenum at all — not against Barium Sulfate, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.
If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.
Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.
Molybdenum safety at a glance
Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Molybdenum in Pregnancy & Breastfeeding
When used orally and appropriately. Molybdenum crosses the placenta by passive diffusion and is exchanged freely between the mother and fetus. However, molybdenum is safe when used in amounts that do not exceed the Tolerable Upper Intake Level (UL) of 1.7 mg/day for women 14 to 18 years, or 2 mg/day for women 19 years of age and older.
When used orally in high doses. Molybdenum might not be safe during pregnancy when used in doses exceeding the UL of 1.7 mg/day for women 14 to 18 years, or 2 mg/day for women 19 and older.

From our pharmacist’s overview on the Barium Sulfate page
“Barium sulfate (Readi-Cat, Varibar, E-Z-HD) is the chalky liquid you drink so a CT scan or X-ray can see your stomach and intestines, and the 17 supplement interactions on file here deserve genuine attention before scan day. Every ingredient listed acts where barium works, in the gut.”

About Molybdenum
What is Molybdenum?
- Correcting molybdenum deficiency
- Supporting enzyme function
- General nutritional supplementation
- Sulfite sensitivity (popular claim)
Molybdenum is an essential trace mineral your body needs in tiny amounts to help certain enzymes work. Most people get enough from a normal diet, so supplements are rarely needed unless a doctor identifies a true deficiency. At normal dietary amounts it is considered safe, but high-dose supplements should be used cautiously and under professional guidance.
Tablets, capsules, multivitamin/mineral products, liquid drops
An interaction check asks whether these two react with each other — it does not ask whether Molybdenum is a good idea for someone in your situation. Here is what our Molybdenum record says about it on its own.
Molybdenum: dosing
There is no special "treatment dose" of molybdenum for most people, because deficiency is rare and the body only needs a tiny amount. Health authorities have set recommended daily intakes that are met easily through a normal diet.If you choose to use a supplement, follow the dose on the product label and do not exceed it.

About Barium Sulfate
What Is Barium Sulfate Used For?
Brand names: E-Z-HD, Readi-Cat 2, Readi-Cat 2 Smoothies, Varibar
Barium sulfate is used before imaging studies to help doctors see the inside of the digestive tract on X-rays and CT scans. Different branded products are approved for different procedures and patient groups.
Readi-Cat 2 and Readi-Cat 2 Smoothie flavors are used to outline the GI tract during CT scans of the abdomen. E-Z-Paque and Liquid E-Z-Paque are used for single-contrast X-ray studies of the esophagus, stomach, and small bowel. E-Z-HD is used for double-contrast X-ray studies of the esophagus, stomach, and duodenum in patients 12 and older. E-Z-Disk tablets help evaluate whether the esophagus is open (patent) in patients 12 and older. ENTERO Vu 24% is used for small bowel X-ray exams in adults. E-Z-Paste is used in single-contrast X-rays of the esophagus, pharynx, and related areas. Varibar Pudding, Varibar Honey, Varibar Nectar, Varibar Thin Honey, and Varibar Thin Liquid are used in modified barium swallow studies to assess how well a person swallows.
