近年来有不少维生素或保健品会做成脂质体形式,认为其有更好的吸收及生物利用度,因此脂质体维生素成了保健品的新趋势之一。前些天有朋友来咨询,在此对脂质体维生素做一简介,希望对有兴趣的朋友有所帮助。
保健品的新趋势-脂质体维生素
保健品的新趋势-脂质体维生素
脂质体维生素或保健品通俗讲就是跟载体-脂质体结合或者被脂质体包裹的维生素或保健品。作为载体的脂质体是由磷脂酰胆碱(卵磷脂成分)组成,具有双层磷脂膜,即外层为两层脂质的囊泡(图一)。 磷脂酰胆碱是一种两性分子,由亲水的头部和疏水的尾部组成,所以脂质体具有既亲脂又亲水的特性,因此可以将药品、疫苗及维生素等放在脂质体囊泡中而使这些物质避免在胃肠道和血液中被破坏及代谢掉,有益于这些物质的运输和吸收。脂质体的双层脂质膜与人体细胞膜的结构相同,它极容易穿过人及动物的细胞膜,便这些被运载的物质全部到达细胞内,达到最大限度的利用。由于脂质体可非常微细,达到纳米级,成为一种纳米材料,所以又称为纳米脂质体。
那么脂质体的跟常规的维生素和保健品比有什么特点?,一是更好的吸收和利用,理论上讲,它不被破坏和代谢,可以达到百分之百的利用,是许多静脉给药的替代品。二是提高服用的安全性及减少副作用,比如说服用大量常规的维他命C会引起腹胀,腹泻,而脂质体维生素C不会有这些副作用。三是
可以主动或被动向特定靶细胞输送维生素或药物。由于维生素或者药物不被肠道代谢掉,而改变脂质的某些特性,让它能到特定靶细胞吸收利用。
现在市面上有好些脂质体维生素及保健品,包括脂质体维生素C,D,E,K,脂质体镁,锌,脂质体脑白金,姜黄,谷胱甘肽及辅酶Q10等,随着脂质体技术的成熟,将会有越来越多的维生素和保健品会以脂质体形式出现,脂质体维生素和保健品的价格也会更趋合理。
Just what I wanted. Had previously owned same shoe, love them.
- Guam
Been getting these forever, love the fit, 13 4E. Perfect, comfortable.
- Singapore
This is my second Monarch pair. Very comfortable shoes. Ordering another pair soon.
- Liberia
Nike runs about a 1/2 size small. I wear a 10.5 normally and wear an 11 in Nike. Good shoes.
- Singapore
I am very happy to buy this product.The shipment was very fast and arrived in very good condition.Thank you.
- Liberia
I'm a truck driver climbing up and down and inside trailers shoes perform well no falling apart yet so I'd buy them again
- Liberia
I have had a hard time finding these shoes in stores in regular width, so I was really glad I could purchase these at a very reasonable price.
- Switzerland
I have a wide foot and they fit well. I use it for working out, yard work and errands. I would not run in this shoe but on a stair master or bike no problem.
- Singapore
Husband has a wide foot with a high instep. This is the only shoe that fits him comfortably. Have purchased this shoe multiple times. Good price and well made. Will definitely purchase again.
- Singapore
One thing about Nike is their sizes are always really close. Very comfortable shoes. Bought a cheapy pair of shoes in between last Nikes and latest Nikes and it is true that you get what you pay for at least when dealing with Nike.

Overall, I am very satisfied, very surprised, and the moderation and sound insulation effect have been improved, which is really great to use.
2024-01-12 08:58:46--
The sound quality is good, the size is small, the feel is good, it is very convenient to carry, very light, and it is very comfortable to wear.
2024-01-12 08:57:43--
I have purchased these before for instructional coaches at my school district main office - the quality is good and so is the price! Plus, they arrive promptly and are packaged very well.
2024-01-12 08:56:31--
Very enthusiastic seller, I will come next time and hope that I will have the opportunity to cooperate next time. I wish you a prosperous business and the quality is very good.
2024-01-12 08:53:45--
It looks great to wear. The shell is exquisitely crafted, with a good visual experience. The touch effect is very sensitive, and the display screen is also very high-definition. It is used very well, and the fit is very good. It feels perfect when put on, protecting the frame of the watch well. Moreover, the material is light and thin, without feeling heavy. It is worth recommending
2024-01-12 08:51:02--
not as described
2024-01-12 08:50:41--
Shoes arrived and they are packed poorly. This caused the shoes to be crested and bent up. The fabric around the leather was bubbling. Will not purchase again.
2024-01-12 08:49:48--
When I got the shoes they had no bag and had a small dent in the top of the right shoe but over all it’s a great shoe
2024-01-12 08:48:59--
The only problem is that the sole is not rubber.
2024-01-12 08:48:33--
nice shoes
2024-01-04 18:57:17--
Very unsatisfied
2024-01-04 18:54:45--
Very good shoes only problem is the toe box because the holes are not placed correctly but other than that 9/10 shoe
2024-01-04 18:53:08--
The sneakers arw a cool 9/10
Very light compared to the “real”
The red bottom is not tooo far off..can barely te a difference, i could cuz i have the “real” as well…but on feet definitely wouldn’t notice
Jump man on the side should be lower and thicker….again once on feet you cannot tell
2024-01-04 18:51:18--
Ordered these for the kids for Christmas!! Totally happy with purchase ! Shoes are great
2024-01-04 18:50:40--

2024-01-04 18:44:43--
Sneaker came perfect. Look like the regular sneaker and comfortable. True to size. The seller is good with communication. Order took 3 weeks to arrive
2024-01-04 18:44:12--
Hurry up and buy! Shipping took about 3 weeks which is awesome considering where they are coming from ! Nobody would know the difference between these and the originals ! Wish I would have know about this seller along time ago. After I got my first pair and saw they looked the legit I’m most definitely buying more !!! I’m hooked !

2024-01-04 09:14:23--
Plastic crap. Not comfy at all.
2024-01-04 09:13:59--
I wish my pink pair fit me the way these does. I ordered a identical pink pair the same time I ordered these, the pink pair are a 7 in women but I ordered a 7 in men. The blue pair fit perfectly. Not sure where the screw up happened. Be careful what you order from them, and make sure your order is correct before ordering.
2024-01-04 09:13:59--
nice good quality shoe but runs small. I ordered my normal size and the shoe is too small.
2024-01-04 09:13:16--

I was shocked at how good the quality of these shoes were. i was not expecting them to be perfect match to the original. they do run slightly big which i was expecting so i ordered the ones that fit me perfectly. again, great quality and i will order again soon.
2024-01-04 09:04:40--

super bien fait je suis très très satisfaite
2024-01-04 00:05:21--
Very I satisfied with this order. I had placed 4 orders form this seller and the big loonies Vuitton bag felt so cheaply made it was so think and it smelled horrible like chemicals. The small**bag had paint in it from the dust bag it came in the**words were painted in the dust bag and smeared to the bag. The wallets had an awful smell also came with paint on it. Worst items I have received from Dh gate. Tried reaching to the seller and delayed answered did not resend me the items. So my payment was released to them. I got multiple items due to reviews being so good that I decided to purchase multiple things and all my items came in bad.. (Real Review) definitely will take my business elsewhere.
2024-01-03 23:56:52--
Beautiful and its realistic. thanks
2024-01-03 23:55:31--
The seller was very polite the product was very accurate
2024-01-03 23:51:05--
so lovely! definitely recommended
2024-01-03 23:50:39--
Really quick delivery. The bag is amazing quality and it was packaged really well
2024-01-03 23:50:06--
So happy with my purchase from this seller! Ordered the grey and light pink. They do have a plastic smell to them but that will fade if I give them an airing. Took about 2 weeks to arrive. Overall I would definitely recommend this item and seller.
2024-01-03 23:49:48--
These are fantastic! I have ordered multiple times and been happy every time. I have the black one as well as the red. They are both beautiful and stand up nicely. Shipping is pretty quick to Canada. Took less than three weeks. I highly recommend this seller. Thank you so much
