Capsule ShellCapsule
Generic capsule shell where the label does not specify the material. Common materials are hypromellose (HPMC) for vegetarian capsules and gelatin for traditional capsules — both are GRAS-listed and safe. Fish gelatin and pullulan variants also exist.
How to Take It
Best taken in the morning
Contains Rhodiola rosea, which is stimulating — keep it to the morning. Take it with food — the zinc in it is what makes this kind of product feel nauseating on an empty stomach.
With food
Tyrosine does better on an empty stomach, but something else in this bottle needs food. Taking the whole product with a meal is the better trade — an upset stomach is why most people stop.
Keep it away from protein-heavy meals and iron-rich meals
Space it a couple of hours from Iron and Calcium
On the label
As a dietary supplement, take 3 capsules, 1-2 times daily, between meals.
General guidance based on the ingredients, not a substitute for the label or your doctor.
