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
Hair Growth Supplement
- AminoMar marine complex (1,072 mg) with trial data
- Favorable mention in a 2023 JAMA Dermatology systematic review
- Full label disclosure with modest 240 mcg biotin
- Recommended by board-certified dermatologists on TikTok
- About half Nutrafol's monthly cost
- No named third-party certification
- Trials are small and company-funded
- Some buyers report stomach upset or constipation
- Marine ingredients (oyster extract) rule it out for shellfish allergies
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.

Hair Growth Supplement
One of the better-supported hair supplements, with a transparent label and a sensible biotin dose, at a lower monthly cost than Nutrafol. The evidence is still small and company-funded and there is no third-party certification, so treat it as a three-to-six-month experiment alongside a proper diagnosis.
