The length of time for the expiration date or "best used before" date depends on the type of product, as well as the brand.
Perishable items (such as flax oils or certain probiotics) generally have shorter expiration dates. Although our warehouse is fully air-conditioned, these more fragile items are put in cold storage (freezer or refrigeration unit) for maximum freshness.
Our receiving department does its best to verify and then enter the correct expiration dates for all incoming products. However, discrepancies do occur from time to time. This being said, the exceptionally high turnover at iHerb ensures that our inventory is among the freshest in the industry.
Discussion: Peak K2 is menatetrenone (MK-4), a form of vitamin K2 made in the body form phylloquinone (vitamin K1) and distinct from the menaquinones made by probiotic bacteria. Available science indicates that vitamin K2 — and especially menatetrenone — is superior to Vitamin K1. Clinical trials have shown that high-dose vitamin K2 does not cause excessive or abnormal blood clotting, although it will interfere with "blood thinning" medications.
Adult Dosage: Take 1 capsule up to three times daily with food, or as directed by a qualified health care practitioner.
Microcrystalline cellulose.
Capsule: hypromellose.

I purchased this to round up all that calcium in my body and in my arteries and deposit it in my bones. Two things: OMG! It removed ALL of the plaque from my teeth. Seriously, I read about that somewhere and thought it was a load of bunk. This stuff works. My left hip and lower back do not hurt any longer. Its been 11 years since I've been able to sleep on my left side. My dentist is going to freak out during my next dental exam later this month. How I took it: 3 x a day with meals. + Calcium Orate 3 x a day with meals. (85mg each) This is about 95% absorbable, unlike other forms Calcium that are from 15% to 65% absorbable. + Vitamin D3 2000IU 3 x a day with meals. + Nutribiotic Meta-C 500mg 3 x a day with meals.

I bought this product as it was stated on iHerb website that "Other Ingredients: Microcrystalline cellulose". It actually contains sodium stearyl fumarate. I'm not happy at all.

The pills are small and easy to swallow. The effects on my body to increase the flexibility of my bones will be seen later than sooner.

The AOR Peak K2 I received has sodium stearyl fumarate in it, a synthetic ingredient, which is different than what was in the description and picture on the website, which showed only cellulose and hypromellulose that are know to be safe . I never would have made this purchase if it had been accurately described as having the sodium stearyl fumarate ingredient. I thought it would be OK, because I took the dose of K2 MK-4 before without sodium stearyl fumarate. I found this K2 MK-4 with sodium stearyl fumarate made made me feel sedated, unlike the K2-MK4 that had no strange effect without the added ingredient. I did research and found that studies on rats and dogs found that sodium stearyl fumarate is found to be absorbed into the body. I could not find any long term studies done on it.

I was given this supplement to take with other supplements. Suppose to be good for bone health. Easy to take and no side effects!

After the second day the plaque on teeth will minimise, leaving them nice and smooth. There has been extensive research on k2 involving removing plaque from arteries. It all makes sense to me and when it come to health I like to use common sense and logic. Do combine it with D3 and vitamin A or fish oil for optimal effect. The price is also very good for the amount of k2 you get.
