No joke, this is an understudied phenomenon, but vitamin K + riboflavin is very likely to square off your jaw and give you space for wisdom teeth if the dosage is right. Mew has good ideas, but the only takeaway people seem to get from him is how to use the jaw and where to hold the tongue. There are many things that affect facial morphology—not the least of which are thyroid hormones. Boron is a trace mineral of seeming importance in this area, but it would not surprise me if a lack of trace minerals in general from failure to eat a varied diet or nutrient dense foods—such as leafy greens, liver, seafood, etc—may also have a major negative impact. If you decide to supplement vitamin K, it is helpful to also supplement vitamin E, as taking only one can deplete the other. The situation is similar with riboflavin where you don't want to supplement it in the complete absence of other B vitamins. Estrogenic influences in general affect facial development in a negative fashion. I report a positive experience in my own case after having supplemented vitamin K2 (MK-4 or menatetrenone).

>A rat model of the vitamin K deficiency embryopathy shows that the facial dysmorphology is preceded by uncontrolled calcification in the normally uncalcified nasal septal cartilage, and decreased longitudinal growth of the cartilage, resulting in maxillonasal hypoplasia. The developing septal cartilage is normally rich in the vitamin K‐dependent protein matrix gla protein (MGP). It is proposed that functional MGP is necessary to maintain growing cartilage in a non‐calcified state.

>Developing teeth contain both MGP and a second vitamin K‐dependent protein, bone gla protein (BGP). It has been postulated that these proteins have a functional role in tooth mineralization. As yet this function has not been established and abnormalities in tooth formation have not been observed under conditions where BGP and MGP should be formed in a non‐functional form.

>In an attempt to elucidate the precise role of TH in the developing eyes and adnexa (orbit, lids, nasolacrimal structures), we analysed the craniofacial and eyeball developmental characteristics in a rat model of congenital-neonatal hypothyroidism (HG), induced by combined chemical-surgical thyroidectomy. […] significantly reduced values for head parameters (25% less), optic primordia area (0.053 ± 0.0085 vs. 0.111 ± 0.012 µm2; p < 0.05) and volume (3.96 ± 0.141 vs. 8.09 ± 0.123 µm3; p < 0.05) were found in the HG with respect to the controls. In addition, a delayed prenatal eye closure and postnatal eye opening took place in the treated rats. The photoreceptor and ganglion cell layer thickness displayed significantly lower values (p < 0.001) in HG, at each developmental time point. Postnatally, a delay in photoreceptor outer segment morphogenesis (in relation to retarded disc formation) and significantly lower values for ganglion cell nuclear volumes (p < 0.001) and nuclear pore density (p < 0.01) were observed in the TH-deficient animals. All data suggest that TH play a pivotal role in the development of the face and eye.

What about an adult though? I think mewing is great, but if you're already fully developed, then all it's going to do is give you the correct oral posture and strengthen the jaw muscles for a leaner, sharper jawline. It probably wouldn't affect bone structure, unless you start doing it while you're a teenager or something.

For fuck's sake:

STOP SPAMMING EVERY THREAD WITH WORTHLESS FUCKING MURINE STUDIES

If even half the things that worked in mice worked in people, we would all be jacked to hell, cut to shreds, and have massive fucking cocks without lifting a single weight.

That being said, there are plenty of other good reasons to take K and E. For K I recommend the product Koncentrated K. It's 45 bucks, but when you calculate the unit price for the massive amount of three different types of vitamin K you get, it is very cost effective. Also you can take only one a day and still get a huge dose of K, which makes the bottle last two months. You should also take a form of Vitamin E that has all eight forms of tocopherols and tocotrienols. I take NOW's advanced Gamma E complex.

Also, Mew has stated several times the nutrition is important, but doesn't focus on it because Price has already covered it.

Muscles determine the shape of your bones, even into old age. If you have a muscular imbalance, they will start to pull your bones out of shape. You bones are very much alive and active, even if they don't grow in size after your growth plates close. Work your quads like crazy and let your hamstrings languish, and in a few years you'll have curved femurs.
