Which is better for weight loss?

Neither is proven to cause weight loss on its own. Obvi adds green tea, garcinia and Morosil to a thermogenic blend; OLLY relies on chromium picolinate to curb cravings. Pick based on whether you want a multi-ingredient burner or a simple craving aid.

Which is better for skin, hair and nails?

Obvi, clearly. It supplies 8 g of hydrolyzed bovine collagen and biotin per serving. OLLY contains no collagen or biotin.

Is Obvi worth the extra money?

At $19.97 versus $14.25 at Amazon as of November 6, 2026, the gap is $5.72. You pay for collagen, biotin and a larger 120-capsule bottle, but you also take four capsules a day instead of one.

Which is easier to take daily?

OLLY. It is one capsule a day. Obvi requires four capsules daily, and users report a cayenne burn if they are not swallowed quickly.

Do either contain stimulants?

Obvi is labeled caffeine-free and stim-free. OLLY lists green tea but no caffeine amount, so treat it as mild.
