  • Size 4 gelatin capsules are the smallest capsule available on the market, and are great for small children and pets.
  • They close easily, snap tight and have the lowest incidence of dents of all the other gelatin capsules available on the market today.
  • All of our empty capsules are BSE Free, Kosher and Halal Certified, Preservative Free, Gluten Free and Allergen Free.
  • They are manufactured in India, where the cattle are raised under strict regulations to produce high quality gelatin.
  • Our size 4 gelatin capsules are completely tasteless, odorless and colorless, making them perfect for your custom herbal supplements.

Empty gelatin capsule sizes range from size 4 (which is the smallest), all the way up to size 000 (largest).

The amount of powder that you can fit inside each empty size 4 gelatin capsule varies depending on the density of the powder, which is why you will see a weight range that each capsule can hold.

Dense powders such as Bentonite Clay and Beet Root Powder will fall at the higher end of the range, whereas light powders such as Ginkgo Biloba and Ceylon Cinnamon will fall toward the lower end.

Here is a breakdown of the approximate volume each empty gelatin capsule can hold:

  • Size 000 – 800-1600 mg
  • Size 00 – 600-1100 mg
  • Size 0 – 400-800 mg
  • Size 1 – 300-600 mg
  • Size 2 – 200-400 mg
  • Size 3 – 150-300 mg
  • Size 4 – 120-240 mg

perfect for cats

I have a cat who has to take one quarter of a metronidazole tab..I break it up, put it in the capsule, roll it in baby food and down the hatch!! These are great for giving nasty meds to a small animal

Shirley M.

Cat will take his meds now

Bought because we needed to put our cat on meds that tasted horrible. With the capsule no taste no smell and Spitfire takes his medications with a minimum of resistance.
