New Vitamin D/Covid Study

 

IMPORTANT NEW VITAMIN D FOR COVID STUDY. There have been several studies showing a relationship between Vitamin D intake and Covid - long story short - having your levels correct makes an ENORMOUS difference in risk and outcome should you contract Covid-19. This body of evidence has been strengthened even more but a full randomized controlled clinical trial - the gold standard in research and WOW.

The first randomized controlled trial (RCT) of vitamin D in COVID-19 has just been published (https://www.sciencedirect.com/science/article/pii/S0960076020302764?via%3Dihub) The results are astounding: vitamin D nearly abolished the odds of requiring treatment in ICU. Although the number of deaths was too small to say for sure, vitamin D may actually abolish the risk of death from COVID-19..

You should ALWAYS take Vitamin D with vitamin K2 which is the fat-soluble version of K. K works synergistically with D to make sure calcium goes where it is supposed to - into your bones - not your tissues or arteries.

Ideally get your levels checked and then supplement - you can get a blood test or a finger stick test and neither require a prescription. You want your blood levels between 40 - 80 ideally. The only way to KNOW this is testing. For most Caucasians who do not get much sunlight you will need to take 5,000iu per day of Vitamin D3 to get into this range, but it can vary considerably based on genetics. I require 10,000iu per day in winter months to stay there. People of color require even more. Sunlight can and does create D in most people very well, but you have to be careful of getting burned.

Now is the time to be getting your levels optimized as we head into fall and winter - do not let those levels drop! There are many other benefits to optimizing D levels including cardiovascular health, bone health, muscle mass in aging adults, etc. This list is long and impressive - single most important supplement to get right!

How to Avoid the Nine Biggest Beginner Gym Mistakes

 

Watch this short video to learn how to avoid the 9 most common beginner mistakes at the gym.     This will give you a simple guide to achieving the results you want in the shortest time possible at a gym: https://youtu.be/-NL1_upNzQU  

Psychological Stress and Exercise Recovery

 

We all know that stress impacts our lives, but what may surprise you is that stress directly impacts how you recover from workouts.     Chronic psychological stress literally increases muscle soreness after a workout and slows down recovery.     This study above proves it:    https://pubmed.ncbi.nlm.nih.gov/24343323

At the same time workouts can help reduce psychological stress so not working out is NOT the answer.      Balance intense workouts with low intensity activity and activities which bring your focus into the moment such as meditation, yoga, playing games, etc. to get the benefits of exercise while enhancing recovery!

How Much Time Should You Rest Between Resistance Training Sets?

 

One of the most common questions about weight training aka resistance training is how long should you rest between each exercise set?     If you take a look at the relevant research concerning this topic there are some good answers.

For a long time, researchers believed that shorter rest periods were better for increasing muscle size which was thought to occur because of increased levels of metabolic stress by not allowing complete recovery.    However, research done in 2015 shows that using longer rest periods actually results in better results for both increased muscle size and increased muscle strength.     It is thought that this occurs because longer rest periods allow a higher training volume (more repetitions of each exercise).

Another aspect to consider is whether most of your workout uses compound exercises (compound exercises use multi-joint exercises using more muscle mass such as a chest press vs a pec dec or pull-up vs an Lat Pullover).      In a 2012 study researchers found that with shorter rest periods workout volume decreased for both single-joint and multi-joint compound exercises.       However, the decrease in volume in workouts with short rest periods tended to be significantly greater with multi-joint compound exercises vs single-joint exercise (29% reduction in volume with multi-joint as compared to 15% with single- joint exercise). So for strength routines focused on compound, multi-joint movements increased rest time is probably a good idea.

Another study which looked at the effects of rest interval length on training volume discovered another important item:    reduction in training volume occurs mainly between 1 and 2-minute rest periods.    The percentage difference between 2 and 3-minute rest periods is much smaller, except when doing 5 or more sets of an exercise.     So, for people doing 3 – 4 sets per exercise, 2 minutes is a good rest interval, but if doing 5 or more sets you should probably extend the rest interval to 3 minutes.

Another important piece of information is that recreational lifters who self-determine rest periods tend to rest just under 2 minutes between sets meaning that for most lifters doing 3 to 4 sets of several exercises whose goal is increased muscle size and strength you probably do not need to time your rest intervals and can go just go by feel.

Timing rest intervals becomes more important for advanced resistance training such as Power Lifting and Bodybuilding, but for most of us we can just go by how we feel!

How Sugar can Sabotage Your Weight Loss Program

 

Many people notice that eating breakfast makes them hungrier throughout the day, and this is probably NOT their imagination!   In this case the culprit is likely what they eat.  Specifically, refined carbohydrates, including sugar, can drive hunger particularly if they are consumed with little fat or protein.

A recent study tested this hypothesis with 16 healthy young women between the ages of 18 and 30 who had a stable body weight for the last 3 months.  Anyone with diabetes or on medications that affect appetite was excluded along with people who were allergic to any part of the meals given as part of the study.

Participants fasted for a minimum of 8 hours prior to the study.  In the morning participants came to the laboratory and were given a standardized test meal consisting of passion fruit juice, one cup of coffee, French bread and 5 grams of margarine.   The two drinks had no sugar added and the participants were instructed to sweeten to their preferred taste.

The sugar container given to the participants was weighed both before and after its use by each person to know the amount of sugar each person added to their drinks.   After completing the entire meal participants did not eat or drink anything (except water) until lunchtime.

Lunch was served 3 hours after breakfast and consisted of pasta with tomato sauce, and participants were instructed to eat until they felt satisfied. 

Study Results

The participants were divided into two groups based on the amount of sugar they elected to add to their breakfast.   The high sugar group added about 25 grams of sugar to breakfast while the low sugar group only added 14 grams of sugar. 

  

Both groups were evaluated for their perception of hunger and satiety.     The high sugar group had significantly higher levels of hunger during the three hours after breakfast AND consumed significantly more pasta at lunch!

Take Home Message

Avoid high sugar breakfasts such as standard breakfast cereal, fruit juices (eat fruit don’t drink it!) and consume 15 – 20 grams of protein and a small amount of fat.   Also try to add higher fiber carb choices like berries instead of banana, adding spinach to an omelet, etc.      Examples include an omelet with spinach with berries or a shake with protein, greens, and small amount of MCT oil for fat.

How Many Repetitions and Sets are Required to Get Results from Weight Training?

Many hours are spent in heated debate on this topic, but the truth is that the number of reps per set and number of sets per workout are secondary measures.       A close review of the scientific research shows that the weight of evidence does NOT support the idea that different numbers of repetitions have differential effects on muscular strength and endurance.       Furthermore, a review on this subject concluded that “all these studies strongly suggest that within a reasonable range of repetitions, approximately 3 to 20, there does not appear to be a specific number of repetitions that will elicit more favorable gains in muscular strength, power or hypertrophy.”

What does matter then?   It is ALL about reaching momentary muscular failure (meaning that you cannot complete another repetition of an exercise in good form.     If you do not reach muscular failure or come very close the reps and sets will not produce results.     Perfect form is part of this equation because perfect form means keeping tension in the targeted muscle/s throughout the entire repetition and not using momentum.     For example, allowing the weights being lifted to settle on the top of the weight stack means you are unloading the muscle – NOT what we want to do!     Throwing weight using momentum is another way you can deload the muscle.   The key is performing smooth, steady repetitions throughout the range of motion for an exercise with no deloading until you reach momentary muscular failure.   

For beginners one set to failure between 8 – 15 repetitions is plenty for each muscle group.   Over the longer haul repetitive sets may become necessary to make progress – but never sacrifice reaching muscular failure and perfect form to do extra sets!

Coronavirus Supplement Guide

Although there are no cures or guaranteed ways to prevent a person from becoming infected with Coronavirus other than preventing exposure through social distancing, hand-washing, and mask wearing there are nutritional supplements that can potentially help minimize symptoms.      As always it is critical to discuss any and all nutritional supplements you take with your physician and always contact your physician if you feel you are experiencing symptoms of Covid 19!

So what are these supplements?

Quercetin – is a plant chemical with strong anti-viral activity that is proven to prevent and mitigate all sorts of viral infections as well as being outstanding for allergies.    In the case of Covid it is particularly well-suited because it is a zinc “ionophore” which means it drives zinc into the cells which is what the infamous drug hydroxychloroquine does, but quercetin achieves with no side effects and no prescription.    

The best forms of quercetin include it being mixed with bromelain – a digestive enzyme that increases absorption.    Inexpensive and easy to find on Amazon or at Vitamin shoppe – suggested dosage is 1,000mg per day EVERY day until this thing is over – works way better if it is in your system PRIOR to exposure.   To understand more about Quercetin/Zinc and covid read here:  https://articles.mercola.com/sites/articles/archive/2020/06/01/quercetin-lowers-your-viral-infections-risk.aspx?cid_source=dnl&cid_medium=email&cid_content=art2HL&cid=20200601Z1&et_cid=DM554057&et_rid=884631632

Do NOT take Quercetin if you are on blood thinners of any kind!!!

Zinc – if you are routinely eat meat, oysters or pumpkin seeds you probably get enough zinc.   It also makes sense to take a supplement with 15 – 30 mg of a high quality chelated form of zinc like zinc picolinate or zinc gluconate or “Optizinc” which is another chelated form of zinc.   Keep total zinc intake no higher than 50mg per day – too much causes its own set of issues and take with a meal!

Zinc lozenges – zinc lozenges are particularly effective in dealing with all respiratory viruses including Covid and you want to have them on hand and begin taking IMMEDIATELY when you have any symptoms but NOT before then.    Zinc lozenges are NOT something to take all the time - only when you have symptoms!  Best type are zinc acetate lozenges from Life Extension.     You want to ALWAYS have these lozenges available because they are ONLY effective when you start them at symptom onset!     Follow label directions.

Vitamin C – if you take a decent multi and regularly eat fruit and vegetables you get plenty of C for day to day.    However it may be smart to purchase several bottles of liposomal Vitamin C to have available to begin big doses at onset of any symptoms.  This form of C is the most bioavailable form you can get orally.    Start taking 2,000mg immediately and every two hours until you hit bowel tolerance.  Bowel Tolerance refers to the fact that when you take more than you can absorb in your gut your bowels get loose – nothing horrible.   It is KEY to keep taking it more and more till you hit this level and you will find if you are sick you will need to take a lot of it before hitting this point whereas if you are not sick you will hit bowel tolerance much earlier.   C is VERY powerful but ONLY if you get enough in you!

Vitamin D and K2 – if you are not checking your vitamin d level PLEASE start – you can get a test from your doc or order an at home one with finger stick or order your own lab test without a doctor.   Optimizing vitamin d levels is the MOST important thing you can do to prevent yourself from ending up in a hospital in the event you catch Covid and you need to do this NOW!  Taking mega-doses when sick does NOT work nearly as well as getting tested and supplementing up to optimal levels.     

For most people this will require a minimum of 5,000iu per day of Vitamin D3 (only form to take).     ALWAYS take Vitamin D WITH Vitamin K2 – a fat soluble form of K that is critical for optimal absorption and effectiveness of D and is important part of preventing Covid Issues!      20 minutes of direct sunlight during peak sun hours is all it takes for most Caucasians to optimize D levels in most of the US during the summer but do not get burned!    

D with K2 is very inexpensive and you start taking this immediately if you are not sure you have good D levels – particularly if you avoid the sun which is understandable because sun can cause damage if you get too much!   Read this article to give you a sense of how important D is for Covid and how high levels are directly correlated with good outcomes and how low levels with bad outcomes:  

https://articles.mercola.com/sites/articles/archive/2020/05/31/vitamin-d-combats-viral-infections-boosts-immune-system.aspx?cid_source=dnl&cid_medium=email&cid_content=art1HL&cid=20200531Z1&et_cid=DM554053&et_rid=883957575 

Melatonin – melatonin is an extremely potent anti-inflammatory supplement that may help inhibit the cytokine storm that is what causes many of the serious complications in people that end up having big problems with Covid.   Children typically have very high melatonin levels (10 times higher than adults and 20 times higher than adults over 60) which may be one of the reasons they have way less issues with Covid.  Do NOT take melatonin anytime but directly before bed on a day to day basis – the strategy for using it during an active Covid infection is entirely different!!!  It is good to have it on hand in the event you have Covid symptoms: 

Dosage Upon COVID-19 Infection
 If you are self-quarantined at home, the following dosage applies. 
 
Melatonin COVID-19 Infection Dosage:  5 milligrams to 50 milligrams
 
The lower range is for individuals with mild or no symptoms.  The higher range is for older individuals or those with more severe symptoms. 
 
Those taking ACE inhibitors, or have cardiac conditions or hypertension need to consult your doctor before taking high doses of melatonin.  Note that melatonin may lower blood pressure and cause hypotension at higher dosages.  
 
The correct infection dose should ideally be divided into daytime and nighttime doses.

Daytime – 40% of total daily dose, divided into small equal portions to be taken every TWO HOURS.  As stated previously do not take melatonin during the day routinely.
 
Nighttime –  60% of total daily dose, divided into two portions taken 2-3 hours after dinner.  The final dose at night should be completed by 10 pm the latest.

If one is diabetic, or have insulin resistance, DO NOT TAKE MELATONIN before 3 pm.  Melatonin is able to suppress insulin. 
 
Please note that these higher dosages are only applicable during infections only.

Aleve/Naproxen Sodium – if you need to take something for pain/inflammation and you think you may have Covid the safest choice is probably Aleve.    Aleve is a anti-inflammatory like ibuprofen/Motrin.    Aleve is a MUCH better choice if you have Covid and probably better than Tylenol which is a pain killer and NOT an anti-inflammatory.   There is evidence that Aleve (and not ibuprofen or Tylenol) can inhibit issues with clotting that clinicians are seeing with Covid and that it may have direct anti-viral effects against Covid.  So like Vitamin C and Zinc Lozenges would recommend you have a bottle on hand in case you need it!   Do NOT take this for prevention – no evidence it will help and this can cause issues if you take it all the time.   Also do NOT take it at all if on any kind of blood thinning medication!

So in summary:

Quercetin and take all the time

Vitamin D and K – ideally get D levels checked and take necessary amount to get you into optimal range – see article link on D and K above.

Zinc – make sure you get enough on day to day basis – take 15 – 40mg per day in supplement form either from multiple or zinc supplement

Zinc lozenges – only to use when you have symptoms but begin IMMEDIATELY

Lipsomal Vitamin C – have several bottles on hand if you start feeling symptoms immediately ramp up dosage as described in Vitamin C section above.

Aleve – have on hand for pain or fever from Covid

Melatonin – to take in higher doses ONLY if you have symptoms

While these supplements may help and there is sound logic behind using them - they do not replace social distancing, mask wearing, proper nutrition, exercise and sleep – no supplement can replace these!   As always contact your physician immediately if you feel you have symptoms of Covid 19.
