Collagen is the major structural protein in connective tissue and the most abundant protein in the human body. It is responsible for maintaining the strength and flexibility of bones, joints, skin, tendons, ligaments, hair, nails, blood vessels and eyes, among other tissues throughout the body.

Best Collagen Types 1 & 3 contains pure collagen protein, providing the fundamental building blocks for growth and maintenance of healthy tissues. Taken as a supplement, this product provides the body with the raw material needed to support the strength and integrity of essential structures. Best Collagen Types 1 & 3 is enzymatically hydrolyzed into component amino acids with a low molecular weight for optimal absorption and utilization by the body. Vitamin C is added to the formula, as it is an essential nutrient required for collagen synthesis by the body.

Good Product
I have been suffered slight pain in my knees for few months before I came to know this product. After I have started taking collagen, the pain started to decrease. I have been taking it since mid of Dec 2015, now my knees are totally free from pain. I’m heaving tearing eyes problem almost every morning or in air-condition environment which I need to keep cleaning off the excessive tears. The tearing eyes condition improved a lot after I have started taking collagen, now I seldom need to clean off the excessive tears. (Tearing is a normal function of the eye. Excessive tearing eyes that are not from normal crying, can be a sign of an underlying health condition or disease.) Also nails condition look smoother. I have placed order to purchase again. I will continue taking this product. Highly recommend it to anyone with joints issues to try it. I saw some reviews said after taking it seemed to increase the knees pain and joints started aching even more but should continue taking it to see improvements after a few weeks. Not all product works for everyone, but you never try you will never know. I like to shop for supplements in iHerb.com as their prices are reasonable. Now iHerb introduced their Loyalty Credit Program, which with every purchase you gain a credit of 10% of your order amount! You get to save more money!

After 8 weeks I sow a good change at my nails. They were broken and now much better. Also my hair is curly again like years ago. I believe it works.

Happy with it

This product was recommended by my son-in-law who used it as a supplement after workouts. The recommended doze seemed too high to me, so I decided to start with 2 caplets once a day, and there is visible improvement with the color of my skin after 3 weeks of taking the supplement. I may update the review later.

I've been using this product for nearly a year and have found that my nails grow much faster than before. I have to trim them about once a week now. My hair and skin also look pretty good for my age.
