It’s okay, very lemony flavor and smell!
[This review was collected as part of a promotion.] Has a nice texture, strong lemon flavor and honestly a bit of an odd aftertaste. I’ve use it for 1 month and haven’t noticed a difference, however I’m going to keep trying to give it the best shot!

Great supplement!
[This review was collected as part of a promotion.] This product has seemed to improve the look of my skin, nails and hair. I was surprised that it didn’t have an overwhelming smell or texture, and it’s actually pleasant to take. All it takes is one small dropper full daily to get the desired effects. I will definitely use this product again.

Not for me
[This review was collected as part of a promotion.] Easy to use, just a few drops in your drink of choice and stir. I don't eat seafood, so I had a hard time getting past the fishy smell and oily texture.It added to the drink. If you eat fish, it might not be as off putting, but for that reason, I really didn't like the product. I don't feel like I used it enough to see any results so I can't really comment on whether or not it works.

Easy-to-take collagen with a mild taste and great
[This review was collected as part of a promotion.] I’ve been using the Why Not Natural Liquid Marine Collagen + Biotin for a few weeks now and I like how easy it is to take compared to pills. The taste is actually pretty mild and not overly fishy, which was a big concern for me. The dosage is simple with the dropper, and I feel like it absorbs well. The formula seems clean and pure, and I appreciate that it combines collagen with biotin for added benefits. It feels like a good value for the quality, and I’ve started noticing slight improvements in my hair and skin

Wow!!!what a difference
[This review was collected as part of a promotion.] I' have never tried WHY NOT NATURAL MARINE COLLAGEN + BIOTIN lemon flavor before and first I have to say the lemon flavor is amazing. Makes it easy to take. After using this product for about 2 weeks i can see a difference in my skin and nails . Such a big improvement. I definitely will continue using this product.

Easy to use
[This review was collected as part of a promotion.] Easy to use, just add a dropperful to 8bounces of water. It has a very faint lemon taste but nothing overpowering. Comes una glass bittle with the dropper for easy use. I've got no issues with side effects. I've used it for a week now and am still monitoring the benefits.

Tastes like water, not like lemon
[This review was collected as part of a promotion.] This is an interesting one. Lots of collagen plus biotin (which, fyi, let your provider know if you’re using biotin and need a thyroid check, it can impact results). The instructions are pretty straight forward, add a dropper. Not sure to how much water but my cup is about 10 ounces and I can’t taste it at all. It seems like it would be thick in its appearance, but it mixed in easily. The bottle is heavy and the dropper is a nice quality. My water still tastes like water, so I guess that’s a plus.

good source of biotin and collagen!
[This review was collected as part of a promotion.] this product is really easy to use with the provided dropper, the lemon flavor doesn’t really change the look or taste of water so i’ve found it easy to incorporate in my daily routine. good source of biotin and collagen, and doesn’t have a fishy taste.

Meh
[This review was collected as part of a promotion.] I’m ambivalent about this. It’s really easy to add to drinks and doesn’t really make a noticeable change in taste, but u als don’t note any change in my skin, hair, nails, or anything else it’s supposed to affect.

Good
[This review was collected as part of a promotion.] Why Not Natural Liquid Marine Collagen + Biotin is well suited as a basic additive for skin, hair and nails. It has a pleasant taste with a slight sourness, a convenient format and easy to use. The effect is soft : with regular use , you can notice an improvement in the skin condition and strengthening of the nails.

Great Supplement
[This review was collected as part of a promotion.] I haven't been able to use the product for long but I feel it has already made my nails stronger. The dosage is extremely high though, which is slightly high being 16,667% of your daily value, so I take one dropperful of it in a small cup of water. As it is ingested it absorbs well into the body, it smells like lemons and taste like lemons.

Took a minute to find the right water ratio but wa
[This review was collected as part of a promotion.] I’ve never had anything like this before so I wasn’t sure what to expect. I did the largest serving my first time, and I used too much water I think because the lemon flavor was subtle. Once I got the right ratio for me, it was quite good! The ingredients are really good and I am excited to see what my long term experience is like with my hair and nails. I am a male so hair is on the thinner side and hope to see a bit more thickness. I have been using this once a day and use about 12oz of water.
