Pros and cons
Liposomal Glutathione Direct Strips
- Fully disclosed amounts with no proprietary blend
- Pleasant sour-lemon strip that dissolves without water
- Made in the company's own California facility
- Oral glutathione raised blood levels in a six-month trial at 250 to 1,000 mg a day
- Individually sealed strips are easy to carry
- 80 mg per strip is well below the 250 to 1,000 mg a day used in studies
- About $1.23 a strip, or roughly $3.70 a day to reach a studied dose
- Absorption and brightening claims rest on small, company-affiliated data with inconsistent figures
- Contains FD&C Yellow No. 6 despite an "additive free" badge
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
Liposomal Glutathione Direct Strips
These strips are a pleasant, no-water way to take glutathione, made in the US with a fully disclosed formula. But one strip supplies about a third of the lowest dose studied, the skin-brightening evidence is modest, and reaching a studied dose costs about $3.70 a day. The marketing runs well ahead of the evidence, so buy it for convenience rather than promised results.

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.
