High Quality product

Posted by odereviews on January 25 2013 | Verified Purchase

I’ve been suffering from knee pains for 13 years, and I have gone through multiple ACL surgeries. There’s still at least one knee surgery coming later this year. I’ve been trying various health products from iHerb to relieve knee pain. Superior source’s Vitamin K2 , 100 mcg, seem to help rather nicely with joint damage (bone-to-bone contacts thanks to Osteoarthritis of Knee). Menaquinone-7, should be the best form of Vitamin K2. I like the quick dissolving tablets, and serving size is only one tablet per day. I don’t like to eat dozens of tablets everyday. :) I have used Superior Source’s products before, and these provides great quality once again.

Thanks for your feedback!

Such goods should not be sold. They should return my money.

The product was no vitamin K2. Tablets were very uneven, erratic, irregular, unequal composition. Some were bitter and others just sweet. One of them was very bitter. Some dissolve 60 seconds and another 10 seconds only. My health has grown worse after these pills.

Thanks for your feedback!

Noticable effect from a tiny dose

Posted by iHerb Customer on May 2 2014 | Verified Purchase

51 and trying to deal with micro-vascular dysfunction and improve circulation. Because of salicylate sensitivity K-2 seems a good alternative. I take K-2 with vitamin D3 and magnesium malate, and it lifts my physical energy. I've been able to swim yesterday in a fairly cold sea water (19*C), without turning blue and breathless as I expected I would. It isn't K-2 alone that improved my circulation (GAGs such as chondroitin and calcium d-glucarate are also helpful for veins and arteries), but K-2 has a certain noticeable effect within minutes of ingestion. Nice small dose, as vitamin K is dangerous in overdose.

Thanks for your feedback!

Very happy with these

Truly instant dissolve on these. Pleasant taste. Teeth seem stronger since taking K vitamins.

Quality Product

Posted by iHerb Customer on October 24 2017 | Verified Purchase

I have found all of the Superior Source products to be good quality. My GP recommended this when I was diagnosed with border line osteopeania (not correct spelling) as a part of a regime to prevent further deterioration. No adverse side effects. Happy with the product.

Thanks for your feedback!

Hoping It is Cleaning My Arteries

Posted by iHerb Customer on April 8 2017 | Verified Purchase

I had read a doctors article who had studied K2 on the internet a year or so ago, that it is supposed to clean your blood and plaque from your arteries. My son talked to a pharmacist who verified my findings. I was elated. My artery that is blocked is too small for a stent. They were going to try and put one in if I continued to have pain but that would have compromised another artery and they would have to put a second stent in. I praise the Lord they didn't do it. They elected to try angioplasty. They couldn't do much with that either so I didn't feel I had anything to loose. I started with this product which also has M7 in it. I haven't researched M7 but will continue to take this brand. I have my blood pressure under control with Hawthorne Extract and Chaga Extract from Host Defense. Chaga is a mushroom and is not really meant for blood pressure but I had a friend tell me about it working so I tried it and it worked for me too. I just wanted to share this with you in case anyone would want to talk to their doctor, pharmacist or research it for themselves.

Thanks for your feedback!

I like it

Posted by iHerb Customer on May 6 2012 | Verified Purchase

I can't tell if it is working yet, haven't used it long enough but I do like the sublingual dissolving tablet. so much easier to take and feels like it might absorb better this way.

Thanks for your feedback!
