DietWorks GLP-1 Companion is a $19.99 tablet that publishes its doses, carrying 100mg of GlucoVantage dihydroberberine, 100mg colostrum, CoQ10 and a shelf-stable probiotic strain.

Overview

DietWorks is one of Windmill Health Products' longer-standing brands, sitting alongside NutraBetic, Country Farms and Garden Greens in its portfolio. The GLP-1 Companion is a 60-tablet bottle sold at around $19.99 through Swanson, Amazon and Target, marketed as supporting metabolic health for people on a GLP-1 programme.

Its distinguishing feature is transparency. Where most of this category hides behind proprietary blends, the DietWorks label publishes amounts: 100mg of dihydroberberine as GlucoVantage, 100mg of bovine colostrum, 15mg of CoQ10 as ubidecarenone, and Bacillus subtilis DE111. It also includes BCAAs, described as supporting a healthier gut environment, and a blend of probiotics and herbs.

The doses are honest rather than heroic. GlucoVantage is dihydroberberine, which human bioavailability research suggests is around five times better absorbed than standard berberine, so 100mg is not directly comparable to 100mg of the ordinary compound. It is still a modest amount next to the 1,000 to 1,500mg daily used in berberine trials. Bacillus subtilis DE111 is a genuinely sensible probiotic choice, being spore-forming and therefore actually able to survive a shelf and a stomach, unlike the anaerobic strains some competitors claim. The CoQ10 at 15mg and the BCAAs are the weakest inclusions, present in amounts unlikely to do much.

What Is Actually in It

  • 100mg GlucoVantage dihydroberberine, with published amounts on the label
  • 100mg bovine colostrum
  • 15mg CoQ10 as ubidecarenone
  • Bacillus subtilis DE111, a spore-forming probiotic that survives shelf storage

Supplement or Medication?

A dietary supplement. Dihydroberberine is a berberine derivative acting on glucose metabolism, not a GLP-1 receptor agonist. The colostrum and probiotic components are aimed at digestive tolerance rather than at appetite, which is a more realistic target.

How You Buy It

1

Buy at retail

Available at Swanson, Amazon and Target.

2

Take as directed

60 tablets covers a full month at the labelled serving.

3

Read the label

Unusually for this category, the doses are printed and worth checking.

4

Judge it over weeks

Glucose metabolism and digestive effects both take time to show.

Who It Is Sold To

  • Adults wanting a transparently dosed, low-cost companion supplement
  • No consultation or clinical assessment involved
  • Dihydroberberine lowers blood sugar and interacts with some medications
  • Colostrum is dairy-derived, relevant if you avoid dairy
  • Not appropriate as a substitute for prescribed obesity treatment
  • Speak to a clinician first if you take glucose-lowering medication

Clinical Oversight and Evidence

Clinical Oversight

None. This is a retail supplement with no clinical involvement. Dihydroberberine interacts with common medications through liver enzymes, so mention it to a pharmacist if you take anything else regularly.

Evidence

No trial on the finished formula. GlucoVantage dihydroberberine has published human bioavailability data and at least one trial comparing it with standard berberine. Bacillus subtilis DE111 is a documented strain with its own research. Colostrum has published work on GLP-1 induced gastrointestinal symptoms. The ingredient selection is evidence-informed even though the combination has not been tested.

Availability and Shipping

Where to Buy

Swanson, Amazon and Target, plus Windmill's own site. Wider and easier distribution than its sister NutraBetic product.

Shipping

Standard retail shipping for shelf-stable tablets. The spore-forming probiotic strain is genuinely stable at room temperature, unlike some competitors' claims.

  • A probiotic strain chosen for survivability rather than marketing appeal
  • Retail availability at Swanson, Amazon and Target

Frequently Asked Questions

What doses does DietWorks publish?

100mg of dihydroberberine as GlucoVantage, 100mg of bovine colostrum, 15mg of CoQ10 as ubidecarenone, and Bacillus subtilis DE111. Publishing individual amounts puts it ahead of most of this category.

Is 100mg of dihydroberberine enough?

It is a real amount given that dihydroberberine is roughly five times better absorbed than standard berberine, but it is still modest next to the 1,000 to 1,500mg of ordinary berberine used in clinical trials.

Why Bacillus subtilis rather than Akkermansia?

Because it survives. Bacillus subtilis DE111 is spore-forming and genuinely shelf-stable, whereas anaerobic strains like Akkermansia are difficult to keep viable in a tablet. It is an honest engineering choice.

How does it compare to NutraBetic?

They come from the same distributor. NutraBetic is cheaper at $9.98 but provides only 15 servings a bottle. DietWorks is around $19.99 for a full month and publishes clearer doses.

Where can I buy it?

Swanson, Amazon and Target, as well as Windmill's own site.

Can I take it with a GLP-1 medication?

Ask your prescriber first. Dihydroberberine acts on glucose metabolism and interacts with several common medications through liver enzymes.

Is it FDA approved?

No. It is a dietary supplement, so it does not require FDA approval before marketing and its claims have not been evaluated by the FDA.

Our Verdict

DietWorks does the single most useful thing a supplement in this category can do, which is tell you how much of each ingredient you are getting. The label carries 100mg of GlucoVantage dihydroberberine, 100mg of bovine colostrum, 15mg of CoQ10 and Bacillus subtilis DE111, a probiotic strain chosen for shelf stability rather than for a fashionable name. That transparency alone puts it ahead of most of this shelf. The doses themselves are modest: 100mg of dihydroberberine is a real amount given its improved absorption but is not equivalent to the 1,000mg-plus of standard berberine used in trials, and the CoQ10 and BCAA inclusions are closer to label decoration than to working doses. At $19.99 for a full month, it is honest, cheap and unambitious, which is a reasonable place for a supplement to sit.
