    PSA: Change in Energin formulation (thiamine replaced by prosultiamine)

    Just a quick heads up. We changed the vitamin B1 in Energin from the thiamine Hcl to the lipophilic analog known as prosultiamine. The latter is an analog of allithiamine, and allithiamine is well-known to forum users for its high bioavailability and ability to raise levels of thiamine...

    Plant protein has much lower cellular uptake/utilization, compared to animal

    Despite the efforts of the powers that be, the evidence against the benefits of plant protein intake continues to accumulate. It has been known since the 1970s that the so-called net nitrogen utilization (NNU) of plant protein is quite low and potentially lower than 0.5, which means that...

    Milk or water are optimal drinks for (oral) vitamin D bioavailability

    Just a quick post about something I thought many people will probably find interesting, considering the widespread use of oral vitamin D supplements. The findings of the study are a bit surprising, considering that vitamin D is one of the "fat-soluble" vitamins and as such is expected to be...

    Navel Application / Absorption Rivals Intravenous One, Skin Route Not Far Behind

    One of the most common questions I get from my readers is "What is the topical absorption rate of your products?" There are a number of studies demonstrating that a solvent mixture of DMSO/ethanol achieves close to 100% absorption no matter where on the skin it is applied. However, we stopped...

    Does High Calcium Intake Deplete Zinc?

    There have been a couple of posts recently along the lines that "the Peat diet" was low in zinc and that high calcium intake would deplete zinc. So I decided to check what information I could find about it. My conclusion: A diet that contains adequate animal proteins from milk, eggs, and...

    Bioavailability, Androgenicity, And Estrogenicity Of DHEA

    I know that some forum members are considering taking or already are taking DHEA. As Peat has warned, and several studies confirmed, DHEA can be converted quite easily into estrogen if the dose used is too high or the person is under stress. In addition, there is some confusion about what route...

    Taurine Enhances Bioavailability Of Vitamins K, A, D, E

    The fat soluble vitamins are a great tool to help metabolism and improve overall health. However their oral usage is sometimes hindered by their requirements for ingestion of fat. In the case of vitamin K2 (MK-4) the fat requirement can be large (35g+) and thus inconvenient to implement while on...

    Oral Magnesium Effective For Hypertension

    Human study, using oral magnesium oxide (1g daily) for 4 weeks. The 1g magnesium oxide provides 600mg elemental magnesium, so the dose is not that high. With a more bioavailable form like magnesium bicarbonate or glycinate a person will probably get the same effects from 300mg-400mg elemental...
