cal_supps_blog1Owing to the incessant advertising from calcium supplements-manufacturing companies, the elderly are often encouraged and coaxed into self-prescribing calcium supplements, in the belief that calcium supplements are good for their health. Traditionally, supplemental calcium has been claimed to be effective for the prevention and management of osteoporosis and fractures. Over the last couple of decades, the prescription and use of calcium supplementation has risen sharply (Tankeu et al. 2017). But is there any proof that calcium supplements work? And, is this exponential rise in the use of calcium pills warranted?

Let us dig a little deeper to know the truth.


A cursory look at the literature immediately throws up the lack of conclusive evidence for the effectiveness of calcium supplements. As if that weren’t enough, use of calcium supplements seem to be strongly associated with cardiovascular events and the risk of death due to cardiovascular or other causes.

The rationale of prescribing calcium supplements, for whatever purpose, especially in the elderly population (already at risk of cardiovascular disease), therefore seems to be quite questionable.


Although there is consensus that calcium intake is crucial for bone health and other physiological functions, the source of calcium intake and quantity remains controversial. While increasing calcium intake through food is both beneficial and safe, acquiring calcium through supplements and pills seems to be neither beneficial nor safe!

cal_supps_blog2It is a popular belief, amongst doctors and lay people, that calcium supplementation is crucial for prevention of osteoporosis – especially, in the elderly in the absence of adequate dietary intake. However, scientific evidence in support of such a ‘belief’ is flimsy, to say the least.

The NIH Consensus Development Panel on Osteoporosis Prevention, Diagnosis and Therapy said in 2001 that ‘adequate calcium and vitamin D intake is crucial to develop optimal peak bone mass and to preserve bone mass throughout life, supplementation (with these 2 nutrients) may be NECESSARY in persons not achieving dietary intake’ (NIH 2001). However, this was later challenged by meta-analysis studies which reported results to the contrary – calcium supplementation did not provide any benefit for hip or lumbar bone mineral density and therefore, did not translate into reduced lumbar or hip fracture risk (Bolland et al. 2008; Anderson et al. 2016).

The authors of a meta-analysis study of prospective cohort studies and randomized-controlled trials concluded quite emphatically that calcium supplementation was not beneficial for reduction of fracture risk (Bischoff-ferrari et al. 2007).


A major health concern of calcium supplementation is the associated cardiovascular disease (CVD) risks; ‘a rising body of evidence’ seems to suggest just such a strong association (Tankeu et al. 2017). Calcium supplementation induced progression of atherosclerosis is often suspected as underlying the association between calcium intake and CVD risk (Anderson et al. 2016).

Calcium supplementation – especially in high doses – may increase the risk of non-skeletal adverse effects: cardiovascular and other (Bolland et al. 2013; Anderson et al. 2016; Favus 2011):

  1. Atherosclerosis (formation of atheromatous plagues within arteries),
  2. Myocardial infarction (heart attack),
  3. Stroke (paralysis), and
  4. Non-cardiovascular adverse effects like development of renal calculi (kidney stones)

Calcium supplementation also increases the risk of all-cause mortality (early death due to any reason) (Anderson et al. 2016; Bolland et al. 2013; Michaelsson et al. 2013)! A Swedish study concluded that ‘high intake of calcium is women are associated with higher death rates from all causes and cardiovascular disease’(Michaelsson et al. 2013). Calcium supplements increased heart attack risk by 31%, risk of stroke by 20% and all cause-mortality by 9%, reported a large meta-analysis study of 12,000 patients (Bolland et al. 2010)!

There is ‘consistent evidence from 13 randomised placebo controlled trials involving about 29,000 participants and about 14,000 incident cases of myocardial infractions and strokes’ that calcium supplements (either take alone or in combination with vitamin D) do increase the risk of cardiovascular risks (Bolland et al. 2011).


Several studies have demonstrated a direct – almost causal relationship – between calcium intake and BP reduction (Dickinson et al. 2006; Cormick et al. 2015). Calcium supplementation has also been shown to be of benefit in pregnancy-induced hypertension (PIH), especially pre-eclampsia (Higgins & Green S 2011).

No one knows why and how calcium intake reduces blood pressure (BP). However, almost everyone agrees that since calcium intake affects vitamin D and parathyroid hormones levels. Low levels of calcium intake may lead to increased compensatory release of vitamin D and parathyroid hormone. Increased vitamin D and parathyroid hormone, in turn, increase reactivity of vascular smooth muscle (muscle of the arteries) which raises peripheral resistance and therefore, BP (Cormick et al. 2015; Paziana & Pazianas 2015; Webb 2003).

Raised BP, therefore, seems to be an indirect effect of low calcium levels (owing to low intake) in an individual (Tankeu et al. 2017; Heaney 2006).

Having said that, the above remains a hypothesis and has not been proven conclusively (Tankeu et al. 2017).


Although much of the literature agrees that calcium intake is crucial for bone health and other physiological functions, the source of calcium intake and quantity remains controversial. While calcium supplementation increases the risk of cardiovascular and other adverse effects, dietary calcium intake (through foods) seems to be safe (Xiao et al. 2013; Bolland et al. 2013).

Researchers are of the opinion that people who partake higher doses of calcium supplements to make up for the daily requirement of calcium, are at the greatest risk of coronary atherosclerosis than the ones that get much of their calcium from food sources. On the other hand, those who increase calcium intake through ingestion of calcium-rich foods exhibit a decreased risk of atherosclerosis and therefore, heart attacks or strokes (Anderson et al. 2016).


As opposed to calcium-rich foods, calcium supplements increase the risk of incident CAC (coronary artery calcification, a measure of calcium content in the coronary arteries – higher the CAC score, higher the risk of a heart attack). Also, it is often suggested that calcium supplementation causes a more rapid rise in serum calcium levels, which causes a hypercoagulable state (blood thickens and is more likely to coagulate and contribute to plague formation) (Leifsson & Ahren 1996). This hypercoagulable state increases the risk of cardiovascular mortality (Reid et al. 2011).


As if calcium supplementation itself wasn’t bad enough, many people resort to taking high doses of calcium supplements. A tablet of calcium typically contains 500 to 650mg of calcium. Typically, users resort to popping in a couple of pills or more, thinking ‘more is better’. This is not only wrong but harmful because higher doses increase the health risks.

In a large study of 60,000 plus Swedish women, who were followed up for a median 19 years, it was found that women who took higher doses (1400mg/day and above) – compared to those who stuck to 600-1000 mg/day  were associated with higher rates of cardiovascular diseases and death from all causes (Michaelsson et al. 2013). Another group of researchers reported increased risk of cardiovascular events with a dose of more than 800mg/day (Bolland et al. 2010). Chung et al. have also challenged the ‘more is better’ strategy of calcium supplementation; their study found that a dose of more than 1000 mg/day did elevate the risk for CVD and CVD mortality. The equivalent risk-elevating dose for men was found to be 1500mg/day (Chung et al. 2016).

Taking such grave cardiovascular and mortality risks into consideration, Bolland et al. were of the opinion that any benefits of low-dose calcium supplements for bone health are far outweighed by the high cardiovascular risks (Bolland et al. 2008).



Currently, there’s very little evidence that calcium supplementation, especially over and above the daily recommended allowances, is beneficial for osteoporosis or fracture risk. Given that calcium supplementation does not do what it is supposed to be doing but, on the contrary, increases health risks, the argument in favour of taking calcium pills, at this point in time – for whatever reason – is not a very strong one.

Blanket prescribing (by doctors) of calcium supplements for prevention and treatment of osteoporosis and reduction of fracture risks, especially in the elderly (already) at risk of cardiovascular events, should therefore be STRONGLY DISCOURAGED.

If you indulge in self-prescription of calcium supplements, you need to be wary of the adverse effects.

Calcium-rich foods are an effective and a safe way to increase calcium intake and should always be preferred over calcium supplements.

The whole town and his wife seems to be using whey protein.

Whey protein isolate – everybody knows – works; you know it works. It is the best protein for improving body composition (reducing fat while improving lean mass)! Or is it really?!

Whey protein isolate may be the best protein for you in most instances, that may not be the case always! Depending on your fitness goal, whey protein concentrate (and, even casein!) can sometime give whey isolate a run for its money. How is that?!

Well, read on to find out!

However, before we get into the nitty-gritty of which type of whey will best serve your purpose, let us get to know a bit more about why you should supplement with whey, in the first place.

Why should I take whey supplements?

Resistance training causes increase in muscle mass. This is due to increased muscle protein synthesis (MPS) that resistance training induces (Hulmi et al., 2009; Hakkinen et al., 2001; Hulmi et al., 2007). However, intense workouts alone are not enough to keep packing on lean muscle mass; you have to ‘stay anabolic’ most of the time to be able to keep that MPS working for you.

Without complicating matters, here’s a look at how resistance training increases lean muscle mass: a resistance training session causes muscle protein breakdown. This is then followed by repair of the damaged muscle tissue so that the muscles come out stronger the next time you hit the weights. For the muscles to get stronger, however, proteins ingestion (over and above normal needs) is crucial. Needless to say, the process of repair will suffer if you aren’t loading up on proteins.

That resistance training combined with protein supplementation causes muscle hypertrophy is well-documented (Moore et al., 2009; Hulmi et al., 2009; Cribb, Williams, Carey, & Hayes, 2006).  Ingestion of a whey protein supplement either immediately before or after a training session is – considered by some – to be the best for this purpose; also whey increases muscle protein turnover like no other protein. Furthermore, whey protein seems to work equally well in women as well (Josse, Tang, Tarnopolsky, & Phillips, 2010).

Another benefit of supplementing with whey is, improved post-workout recovery  This is likely due to the ‘anti-catabolic’ action of essential amino acids (Bird, Tarpenning, & Marino, 2006; Hoffman et al., 2010; Etheridge, Philp, & Watt, 2008).

What is Whey Protein?

You most likely know that whey is one of the 2 milk proteins – the other being casein. Casein is the more abundant of the two and it is casein that gives milk that white colour. In commercially available cow’s milk, 20% of protein is whey while the rest of it is casein (Hulmi, Lockwood, & Stout, 2010; Ha & Zemel, 2003; Etzel, 2004; Krissansen, 2007).

Whey is produced in large amounts as a by-product in the cheese industry. However, this whey has loads of fat, milk sugar (lactose) and salts in it and is not suitable for improving body composition.

During the process of whey purification, whey concentrate and isolate are produced sequentially. During the initial steps, larger molecules are separated out resulting in formation of whey concentrate. These larger molecules are proteins, lactose, immunoglobulins, amongst other less important ones. To produce whey isolate, cheese whey is passed through an ultrafiltration process (ion exchange or other methods). The ultra membrane filters fat, milk sugar (lactose), salts and other unwanted ingredients leaving behind a pure form of whey (Barile et al., 2009).

Hydrolysates, on the other hand, are formulations where large protein molecules are broken down into smaller fragments. The hypothesis is that this might further increase the rate of absorption of whey. However, this might not be totally true and hydrolysates may not offer much of an advantage over isolates or concentrates.

Types of Whey Protein

Whey is available commercially as either isolate or concentrate. ‘So, what’s the difference between them and which one should I be using’, you might want to ask?

The main difference between the two is the quality and the amount of protein content – isolate is purer and thus will contain almost 100% protein (well, 90-94% to be precise) while whey concentrate will contain protein ranging from 70-85%.

‘Well, that settles it – I am going with whey isolate!’, you might say. Hang on, not so fast! There is more to it than just protein content.

Comparing Whey Isolate and Whey Concentrate

Since whey isolate is higher in protein content, has a better amino acid ratio and thus bioavailability, it is absorbed into your system way quicker than whey concentrate (or any other protein, for that matter). That makes whey isolate the ideal post-exercise anabolic drink (Hulmi et al., 2009). Some researchers have suggested taking whey protein isolate before workouts as well in addition to your routine post-workout shake for maximum benefits (Esmark et al., 2001; Cribb & Hayes, 2006). Quicker absorption will mean almost instantaneous rise in blood amino acids which are then taken up by ‘hungry muscles’.

Having said that, the need for immediate post-workout protein supplementation in now being increasingly questioned (more below).

High protein content and higher quality of protein, however, that does not clinch the deal in favour of whey isolate. Concentrate has something up its sleeve that will make sit up and take notice!

As stated earlier, in comparison to isolate, whey protein concentrate will contain lesser amount of protein (in the range of 70-85%). However, somewhat similar to casein, whey protein concentrate will get absorbed slowly – this helps you stay anabolic for longer! Slower absorption also helps with absorption of other important nutrients from food like calcium. Not a lot of people know this but calcium plays an important role in causing fat loss (in addition to keeping your bones healthy)! Add to that the added benefit of appetite suppression for longer and casein suddenly become an important tool for your fat-loss goals or intermittent-fasting health journey…

Furthermore, whey protein concentrate is loaded with immunoglobulins – this helps boost your immune system and therefore may be beneficial in dealing with the intense stresses of training (especially if you happen to overtrain!).

Whey Isolate


    • pure; contains 90-94% protein!
    • purity means that it is great for gaining / maintaining lean mass while getting ripped (ideal when nearing competition or a photo shoot)
    • contains all essential amino acids in the best possible ratios
    • bioavailability for humans is best amongst all proteins – meaning, of the amount ingested, more is likely to be absorbed. For instance, in a scoop containing 25 g of whey isolate, almost all of the protein in there, will be going into your muscle
    • lightening fast absorption; ideal post-exercise drink – helps you get into the anabolic mode almost immediately


    • pricier than whey protein concentrate – to ensure purity, the commercial production of whey necessitates use of complex filtration procedure, hence the price
    • although whey isolate will help recovery after workouts, it loses out to whey concentrate in some respects. This is so because immune boosting constituents of milk protein like alpha – lactoglobulins and lactoferrins are removed during the purification process

Whey Concentrate


    • lot cheaper than whey isolate
    • has a slower absorption rate than whey protein isolates; thus ensures a steady state of elevated amino acids in the blood and helps you stay anabolic for longer. This also reduces the need for frequent dosing
    • slower absorption helps with absorption of other important minerals like calcium and reducing blood glucose and lipid levels
    • induces appetite suppression which may help longer fasting interval, thereby improving body composition and metabolic disease parameters
    • contains immune boosting complexes (alpha – lactoglobulins and lactoferrins) which help post-exercise muscle recovery
    • helps fight diseases – for instance, chronic hepatitis C (Elattar et al., 2010)


    • some amount of fat will be present so not ideally suited during times when keeping body fat% down is desirable
    • if you have any degree of intolerance to milk and dairy products, you might want to forget using whey concentrate on account of its lactose content – which is missing from the more purer whey isolate


In conclusion, isolate and concentrate are equally good – however, your circumstances – price, training goals and lactose intolerance – should tip the scales in favour of one or the other.

Recent developments

  1. More recently, the presence of a post-workout anabolic window (of opportunity) is being increasing questioned. ‘Not only is nutrient timing research open to question in terms of applicability, but recent evidence has directly challenged the classical view of the relevance of post-exercise nutritional intake with respect to anabolism’ (Aragon and Schoenfeld, 2013). The amount and quality of protein that you consume throughout the day is, now, thought to be more important than immediate post-workout whey ingestion.
  2. BCAAs (branched-chain amino acids – leucine, isoleucine and valine) may be overrated and ‘data do not seem to support a benefit to BCCA supplementation during periods of caloric restriction’ (Dieter BP, Schoenfeld BJ and Aragon AA, 2016).

Really?! I can hear you say! And, you’re not alone! Most people associate testosterone use (and, that of other androgenic-anabolic steroids) with aggression and anti-social behaviour. Which isn’t very surprising, given the amount of rap that these ‘illegal’ substances have had from the mainstream media.

It is indeed sad that testosterone – especially when used as a steroidal supplement – has been maligned beyond belief. So much so, that we tend to associate testosterone (T) supplementation with ‘aggression’ and ‘doping’ or ‘cheating’ more readily than ‘truthfulness’ or ‘pro-social’ behavior. The truth of the matter is that T can, in fact, have positive social influence on the behaviour of men and even produces truthfulness.

Before we get into how the process of lying that is positively affected by supplementation with T, let us try to have a cursory look at what the basis of lying is.

Basis of Lying

Why do we lie? Well, even before someone starts to answer that question, you’ll know the answer will be quite complex. And, no matter how impressive the answer is, you can be rest assured that no one will ever know the complete truth. To date, no researchers, doctors or rational thinking scholars have been able to solve the riddle! Despite immense research in this direction, the psycho-physiological basis of lying is yet to be unearthed.

Some researchers believe that the internal chemistry in our bodies may have a lot to do with our tendency to lie (or be truthful). Of the numerous physiologically active chemicals and substances in our bodies that carry out (almost a million!) physiologically important roles, T has been recognised as one such chemical that influences truthfulness and social behaviour, especially so in men.

Several scientific studies – in the recent past – have demonstrated this positive association between T (supplementation) in men and truthfulness!

The Act of Lying

One of the most accepted of all social rules is the need to be truthful; don’t know how much of a religious person you are, but almost all religious scriptures advocate being truthful for the good of society.

The basis of such a rule is that truthfulness helps build trust amongst concerned parties facilitating mutual social or economic growth (Wibral, Dohmen, Klingmuller, Weber, & Falk, 2012). However, it is an undeniable fact, that no matter what part of the globe you live in, you will always come across deceitful, lying people.

Scientists for long have been studying the reasons – social, psychological and physiological – that make people susceptible to lying (Bok, 1978; DePaulo, Kashy, Kirkendol, Wyer, & Epstein, 1996; Vrij, 2001). However, no one has been quite able to crack it (the reasons).

Recently, however, a connection between T and truthfulness – not to mention, a more socially acceptable behaviour – has been suggested. And, that low testosterone levels may have something to do with lying! Scientific studies have been consistently reporting that men supplemented with steroidal injections of testosterone are more likely to be

    • truthful, and
    • to put on a more ‘pro-social behavior’

Let us get to know why!

Testosterone and the Connection with a ‘Pro-social Behavior’

Let’s have a quick look at what T is before moving on to how it influences truthfulness and a pro-social behaviour.

As we all know, testosterone is the main androgenic hormone of the human male; it is responsible for:

    • development of primary male sexual characteristics – growth of testes and penis during uterine life and again, near puberty
    • development of secondary male sexual characteristics – male pattern of distribution of bodily hair including a beard and moustache, a base voice and increase in lean mass – muscles and bones – imparting more vigor to the male

However, there seems to be more to T that just its influence on the male reproductive physiology. As mentioned earlier, T seems to affect psycho-social human behavior as well.

While research has tended to focus on the connection between aggression and testosterone, recently it is being reported that testosterone may, in fact, (at least under certain conditions) positively influence a man’s social interactions – making him more selfless (Eisenegger, Naef, Snozzi, Heinrichs, & Fehr, 2010; van, Montoya, Bos, van, & Terburg, 2012). One of the reasons cited for such unusual findings (unusual, going by current logic) is the fact that testosterone is principally a reproductive hormone; and, gaining a higher social status is a part of what is called the ‘dominance behaviour’ or the ‘alpha-male behaviour’ (seen so typically in animals) (Eisenegger et al., 2010; Eisenegger, Haushofer, & Fehr, 2011; Mazur & Booth, 1998). Therefore, being socially amicable with a selfless behaviour and reduced lying may be a part of this ‘dominance behaviour’ with the ultimate aim of dominating over other males and securing a female mate!

It is also suggested that pride may also contribute to such pro-social behavior (Wibral et al., 2012).

The acts of – sometimes unwarranted – heroism that men tend to indulge in are also blamed on T combined with such inherent characteristics as pride and the tendency to dominate.

Evidence in Favour of ‘Testosterone Truthfulness’

In a study published in 2012, Wibral and his colleagues reported that T administration may reduce the incidence of ‘self-serving’ lies (Wibral et al., 2012). The authors go on to the suggest how T may positively influence the human male psyche.

    • positively affecting social preferences and choice making
    • improving self-esteem and, therefore, the concern for social standing
    • improving concerns for the belief of others

There is also some evidence that T administration may positively affect social behavior in women too (Eisenegger et al., 2010; Wibral et al., 2012).


Testosterone may not be just a ‘male sexual hormone’; it has a lot to do with the way men interact socially as well. In a nutshell, there seems to be – in all truthfulness (!) – far more to testosterone than meets the eye!

Supplements that I am using right now..

There are millions of amazing supplements to choose from. It is easy to get confused. However, your choice should always be driven by your fitness goals, esp. the short term one.

After a long lay-off due to injury, my goal right now is to lose some % of body fat. However, I’m still getting back into the grove and my training intensity is nowhere near where I used to be.

So the supplements of my focus currently are a pre-work and protein. Nutrex’s Hemorage is my choice for a pre and intra-workout drink. Although not as strong as some other products on the market like Jack 3D, it gives me the right kinda focus for my workouts.

I like the blended protein product from Nutrex – Muscle Infusion; it not only helps fast post workout absorption of protein but also slower absorption of other proteins contained in it, keeping you anabolic for longer. What’s more, I just dig the vanilla flavour; it is awesome in taste, to say the least!

Of course, as usual, omega3s are a big part of my supplement plan.

In a couple of weeks, I will be adding a potent fat burner to my supplements stack…keep following me to get the latest.

Happy lifting!
