Is menatetrenone the same as menaquinone?
Menatetrenone is a menaquinone compound and form of vitamin K2 with potential antineoplastic activity. Menatetrenone may act by modulating the signalling of certain tyrosine kinases, thereby affecting several transcription factors including c-myc and c-fos.
Which form of vitamin K2 is best?
For this reason, a supplement is often recommended. There are two main types of Vitamin K2 available for supplementation: MK-4 and MK-7. While both are forms of vitamin K2, MK-7 has been shown to be more effective than MK-4 at producing osteocaclin and reducing overall cardiovascular risk.
Which vitamin K2 is best MK-4 or MK-7?
The difference is MK4 has a shorter half life in the body than MK7 so to be most effective MK4 ideally needs to be taken in divided doses 2-3 times a day, whereas MK7 can be taken once a day. Also the optimum amounts are different: MK4 is recommended at 45mg a day, whereas MK7 is recommended at 120 mcg a day.
Which is best MK-4 or MK-7?
The current study shows that MK-4 has a poor bioavailability at a nutritional level dose, whereas MK-7 is well absorbed and detectable in the blood at nutritional levels.
Is vitamin K2 the same as MK-7?
Answer: Two forms of vitamin K2 are typically found in supplements: MK-4 (synthetic) and MK-7 (natural, from natto). There are significant differences between them: in paticular, MK-7 has a longer half-life, so a smaller dose can be used. Two newer forms of MK-7 are available that are synthetic.
What blocks K2 absorption?
Consumption of trans fats blocks the action of K2. While trans-fat consumption is now reducing, this has been a factor in our diets. It’s likely that polyunsaturated vegetable oils (seed oils) don’t allow proper absorption of vitamin K2 in the digestive system.
Does vitamin K2 reverse osteoporosis?
One Japanese study found that a daily intake of low-dose vitamin K2 significantly improved vertebral BMD in postmenopausal women with osteoporosis, but there were no significant changes in BMD among postmenopausal women without osteoporosis.
