Hi Michael218,
Thank you for your question. If the lecithin pill is a gel capsule you may have to take it with food. I would check the label to make sure.
The theoretical toxicity from DHA comes from lipid peroxidation (free radicals) when DHA is oxidized. According to your post you are taking 5x120mg = 600mg of DHA? One serving of fish will give you about 1g (1000mg) of DHA. So you would be well below toxicity. Also, I have not seen any clinical studies in humans that show this to be a problem.
The folate type only matters if you have MTHFR gene mutations that lower the natural conversion of folate to the active form (5-methyltetrahydrofolic acid, metafolin) in the body. However, I should point out that choline can recycle SAM-e by a folate independent path. I updated the original post in the (
Notes: About Methyl donors:) section. In this stack, metafolin is used for redundancy.
B12 has extremely low toxicity. I do not see any problem with 1000mcg. If you are able to determine that you are not D3 deficient, then I would not worry about supplementing D3. I am one of those people with darker skin. And since melanin blocks light-induced D3 production, I have to take it.
I have seen personal benefits to POIS in the past from taking creatine. However, I am not taking it now. I think creatine (CREA) is an excellent complement to the POIS Cascade Stack as long as you are familiar with how to
load it. CREA production consumes choline/betaine-TMG in the liver. And CREA supplementation spares the consumption of betaine by the
homocysteine cycles in the liver. This leaves more choline and TMG available for methyl donation in the liver and improves the liver's ability to detoxify through methylation. However, in the rest of the body, creatine does not spare TMG or choline consumption and CREA is not a methyl donor. So CREA is not a replacement for methyl donors.
SAM-e is the sole methyl donor for
more than 40 methyl-group transfer enzymes (methyltransferases) and cannot be replaced by any substance (natural or synthetic). In other words, there are many SAM-e dependent enzymes that no other methyl-donor can interact with (not even choline). It is important to note that SAM-e is not the source of methyl groups. SAM-e is cycled like folate and B12. When supplementing with SAM-e, you are not increasing the number of methyl-groups by any significant amount, you are increasing the number of parallel
homocysteine cycles.
As an analogy, consider the cylinders/pistons in a car engine. SAM-e is the cylinders and TMG is the gasoline. The car cylinders (SAM-e) are cycled and output energy (methyl-groups) each cycle. The more cylinders (SAM-e) you have, the more energy (methyl-groups) you can output per second. Think horsepower. But you still need gasoline (TMG) to make the car run. This is only an analogy and every analogy has its limits. But I just wanted to point out that SAM-e plays a much different role than choline or betaine. So the comparison in terms of methyl-group supplying/sparing should not be between SAM-e and creatine,
it should be between TMG and creatine. And
TMG (supplying three methyl-groups) is less expensive, being ~40% the cost per methyl-group of
creatine (sparing one methyl-group).
In terms of choline (methyl-group) sparing, there is no advantage to taking creatine instead TMG. However, creatine can have a very big benefit on reducing POIS symptoms as a phosphate cycler managing ATP levels.
ATP is required to run the
homocysteine cycles (converting
methionine into S
AM-e by donating
Adenosine). And creatine acts as a phosphate bank, transfering phosphate-groups when ATP is low and accepting phosphate-groups when ATP is too high.
In our car analogy, ATP would be the spark plug and creatine would be the battery. It is an imperfect analogy, but the point is that CREA and ATP supply the energy needed to recycle SAM-e and keep the
homocysteine cycles going. This effect of CREA is not limited to the liver and occurs throughout the body. And since ATP is the main energy carrier, the effects of CREA supplementation can extent far beyond POIS.
Creatine loading involves 20 grams/day for 5 days (5 doses of 4 grams). And then the maintenence phase involving a single dose of 5 grams per day. The reason for loading is that the muscles are greedy and can store ~20 grams of excess CREA before saturating. Any CREA that does not disolve in water will not be absorbed by the body and may cause bloating or other stomach problems. Putting a glass of water in the microwave for 30 seconds before adding creatine monohydrate will help it dissolve better and absorb. Other forms of CREA (i.e. tricreatine malate) may dissolve in room temp water. I am not currently taking CREA because of the complexity of the loading phase and carb requirements. Moreover, I used to cycle off creatine for 2 weeks to give my kidneys a break, but got tired of the on-off schedule.
I hope something here answered your question or at least gave you an idea of how to customize your stack. Let me know if you have any new ideas or new combinations that work.
