**Inositol** has moderate clinical evidence for supporting mood, hormonal balance (particularly in PCOS), and insulin sensitivity — but the studied doses range from 2,000 to 4,000mg daily. At one capsule, you're getting just 500mg, which is only 25% of the minimum effective dose. To reach the clinical range, you'd need to take four capsules per day.

At four capsules (2,000mg), this becomes a reasonably dosed option for your mood and hormonal health goals. The capsule format makes it easy to adjust your intake, and inositol is generally well tolerated even at higher doses — mild GI discomfort is the main thing to watch for.

The key tradeoff is pill burden versus convenience. If you plan to dose at clinical levels, a powder format would be more practical and cost-effective than going through four capsules daily.
