Capsule filler

I suffer from migraine. A few years ago, I discovered that Taurine, an amino acid, does miracles to fix them.

I can purchase taurine in different form:
**Energy drink**
- Pros:
- Ready to consume
- Cons:
- Contains a lot of products I do not need (such as caffeine)
- I don't like the taste
- Quite expensive (compared with other solutions)
- It is not recommended to consume more than one in a day
- Short shelf life

**Capsule**
- Pros:
- Ready to consume
- Somewhat flexible dosage (500mg per capsule)
- Long shelf life
- Cons:
- Hard to find
- Somewhat expensive

**Powder**
- Pros:
- Very cheap (when bought in bulk)
- Easy to find
- Flexible dosage
- Very long shelf life
- Cons:
- Require preparation (mix with juice)
- Require several minutes of mixing for the powder to melt (every minutes count when I have a migraine)

**Solution**
- Buy Taurine powder in bulk
- Buy empty gel capsules
- Fill the capsules manually
