Horsetail and Albiglutide

Here is the interaction we found between these two, with the evidence behind it.

Moderate

ANTIDIABETES DRUGS

Why this applies to Albiglutide

Albiglutide falls under ANTIDIABETES DRUGS — the group Horsetail interacts with.

Theoretically, taking horsetail with antidiabetes drugs might increase the risk of hypoglycemia.
Equisetum myriochaetum has demonstrated hypoglycemic activity in clinical research. In an animal diabetic model, Equisetum giganteum had hypoglycemic effects. It is unclear whether other horsetail species have hypoglycemic effects.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the short version: Albiglutide (Tanzeum) already lowers your blood sugar, and some research suggests horsetail may nudge blood sugar down too. Stack the two and you could, in theory, end up lower than you want. That can show up as the usual low-sugar warning signs, like shakiness, sweating, dizziness, a racing heartbeat, or feeling confused or hungry.

I want to be honest about how soft this evidence is. The blood-sugar effect was seen with certain horsetail species in lab and animal studies, not in solid human trials, so it may not matter much in real life. Still, if you're using both, it's worth a heads-up to your pharmacist or doctor, and keep an eye on your glucose readings rather than changing anything on your own.

From our pharmacist’s overview on the Albiglutide page

“People injecting albiglutide (Tanzeum) once a week for type 2 diabetes are often the same people eyeing supplements marketed for blood sugar, and that overlap is exactly where this list calls for real vigilance. Every one of the 239 ingredients on file touches glucose control in some way, most by adding to albiglutide's glucose-lowerin…”

About Horsetail

What is Horsetail?

Horsetail
  • Fluid retention (mild diuretic)
  • Urinary and bladder concerns
  • Hair, skin, and nail support
  • Wound healing
  • Bone health

Horsetail is a traditional herb most often used as a mild diuretic and for hair, nail, and bone support, but high-quality human evidence is limited. It can cause thiamine (vitamin B1) loss with long-term use, and some related species are toxic, so choose products carefully and talk to your pharmacist or doctor before using it.
