SULU Hair Growth Gummies are sold on Amazon with before-and-after photos, "94% saw visibly thicker hair" and separate pitches for postpartum mothers and women over 50. The label tells a plainer story: a multivitamin gummy with a large dose of biotin and small amounts of several trendy extracts.

It is sweetened with xylitol (0 g sugar, 20 calories). Other ingredients: maltodextrin, pectin, citric acid, fruit juice concentrate, natural flavor, beetroot powder and vegetable oil.
Read as a whole, this is a reasonable everyday multivitamin, most vitamins near 100% of the daily value, plus one ingredient in megadose (biotin) and six in token amounts.
Does It Help Hair Loss?
Biotin: only if you are deficient
Biotin is the product's headline ingredient, at 5,000 mcg a day, more than 160 times the daily value. The best review of the evidence found that every documented case of biotin improving hair or nails involved an underlying deficiency or disorder, and that research supporting biotin in healthy people is limited (Patel 2017, PMID: 28879195). True deficiency is uncommon outside specific medical situations. Our biotin guide goes through who might actually benefit.
The "hair" extracts: far below any studied dose
Saw palmetto is the one with real hair-loss evidence, and the dose used in the best comparison study was 320 mg a day (Rossi 2012, PMID: 23298508). SULU contains 5 mg, about one sixty-fourth of that. Pine bark, bilberry and green coffee are also present at 5 mg each, and silica and hyaluronic acid at 10 mg. At these amounts they are label decoration rather than active doses. If saw palmetto is what you want, see our saw palmetto guide for what it can and can't do.
The multivitamin part: helps only if something was missing
Hair shedding can be driven by nutrient shortfalls, and a multivitamin can correct mild ones. But it does nothing for pattern hair loss, the most common cause of thinning in women and men, and the more useful step is a blood test that shows whether anything is actually low. See which blood tests are worth doing for hair loss.
The claims on the listing
The listing says 94% saw visibly thicker hair after 6 months, 87% of mothers saw less shedding in 90 days, and women over 50 saw "measurable increases in hair density." None of these names a study, sample size or method, and we could not find one published. The before-and-after photos are customer testimonials. Postpartum shedding in particular usually recovers on its own within months, so improvement after 90 days says little about any supplement.
Safety Notes
- Blood tests. At 5,000 mcg a day, biotin can distort immunoassay lab tests, including thyroid panels and troponin, the test used to diagnose heart attacks. The FDA has warned that biotin can cause falsely low troponin results (FDA safety communication). Tell your doctor you take it before any blood work.
- Breastfeeding and pregnancy. SULU is marketed for postpartum hair loss, yet it contains saw palmetto, a plant with anti-androgen activity that is not advised in pregnancy and has no safety data in breastfeeding. The dose is small, but there is no reason to take it. Our postpartum supplement guide covers options formulated for new mothers, including Nutrafol Postpartum, which leaves saw palmetto out.
- Doubling up. If you already take a multivitamin or prenatal, adding SULU doubles several vitamins, including vitamin A.
- Pets. Xylitol is toxic to dogs, so keep the jar out of reach.
- The "FDA" badge. The FDA does not approve or certify dietary supplements. The badge on the listing refers to the factory being FDA-registered, which is not an endorsement of the product.
Who Should Consider It, and What to Try Instead
Consider it only if you want a sugar-free multivitamin gummy and are happy to take a large dose of biotin with it. At about $20 a month it is priced like one.
Skip it if you are breastfeeding or pregnant, have pattern hair loss, or are expecting it to regrow hair.
Better-evidenced options, depending on the cause:
- Pattern hair loss (thinning at the part or crown): minoxidil, the best-evidenced first step for women.
- A supplement with its own trials: Viviscal, which has published randomized trials in women with thinning hair.
- Postpartum shedding: usually temporary. See what actually helps after birth.
- Not sure what's causing it: start with blood tests rather than a supplement.
Our Verdict
SULU Hair Growth Gummies are a decent-tasting, sugar-free multivitamin with a megadose of biotin, sold as a hair growth treatment. The biotin only helps people who are deficient, the extracts are too small to matter, and the headline results cite no study. We rate it 2.5 out of 5: not recommended for hair loss, and a poor choice while breastfeeding because of the saw palmetto.
