Pros and cons
Liquid Morning Multivitamin + Hair Growth
- Provides Lustriva at about the 160 mg daily dose that improved hair thickness in a placebo-controlled trial
- Clean Label Project certified and made in a GMP facility
- Liquid format with methylfolate and methylcobalamin, so no pills to swallow
- Sugar-free, vegan, and free of dairy, gluten and soy
- Most buyers enjoy the Peach Mango flavor
- 10,000 mcg of biotin (33,333% DV) can distort lab tests, including troponin tests for heart attacks
- The hair evidence rests on one 12-week trial of the ingredient, not of this product
- About $2.50 a day, and it lacks iron, iodine, calcium and magnesium
- 1,000 mcg of chromium is far above the Daily Value, and some buyers report stomach upset
Optimal Solutions Hair, Skin & Nails Gummies
- About $0.19 per daily serving for the 80-count bottle
- Fully disclosed label with no proprietary blend
- 4.6-star average across 70,000+ buyer ratings, with frequent praise for the taste
- Label warns to consult a doctor before clinical lab testing
- Free of milk, lactose, soy, gluten, wheat and fish, per the label
- Biotin at 8,333% DV has little evidence of benefit unless you are deficient
- No named third-party certification such as USP or NSF
- Contains gelatin and 2 g of added sugar per serving
- Buyers report gummies clumping together and some skin breakouts
Our verdicts
Liquid Morning Multivitamin + Hair Growth
This is one of the few viral hair supplements that uses its headline ingredient at the dose that worked in a trial, and Clean Label Project certification adds confidence. The trade-offs are real: the evidence is one ingredient study, the 10,000 mcg of biotin can skew blood tests, and $2.50 a day is steep for a multivitamin missing key minerals. Women who want one tasty liquid for hair and daily vitamins may find a three-month trial worthwhile, but anyone with upcoming lab work or a tight budget should look elsewhere.

Optimal Solutions Hair, Skin & Nails Gummies
A cheap, pleasant-tasting and fully disclosed biotin gummy that delivers exactly what its label says. The problem is the premise: for most people without a deficiency, 2,500 mcg of biotin is unlikely to change hair, skin or nails. Buy it as a low-cost experiment if you like, and tell your clinician before any blood test.
