Well the short answer is “right now,” because with the average diet people live on nowadays, it’s almost completely impossible to get the full complement of nutrients the body needs to function at its very best. There’s a very wide range of supplements on the market today, with this variety expanding almost daily, but there are some specific cases in which taking supplements is a must as opposed to merely being an optional consideration for some sort of physical enhancement.
When You Experience Persistent Health Issues
One of the less obvious indicators of the need to supplement your nutritional needs is the persistence of one or more medical issues. Something as seemingly unrelated to the need for dietary supplementation as taking a bit too long to get over the common flu is indeed an indication of underlying health issues. It’s not so much that you need to look directly at perhaps having taken a flu shot to prevent such illnesses, but rather a required look at strengthening your immune system as a whole. Many immune-boosting nutrients we’d otherwise easily get from a fully balanced diet are now only realistically within our reach through supplements. Yes, definitely get the requisite core treatment for whatever illness you may be suffering from, but beyond that some immunity-boosting supplementation is most probably in order.
When There’s a Spike in Your Regular Physical Activity
As one’s life rhythm starts to take a bit of a predictable pattern, your body sort of tunes itself to essentially make the most effective use possible of the nutrients you take in, although there are external factors at play which serve to disrupt that process. If you’ve been following the same daily routine for decades now, your body sort of knows how much nutrients to absorb from the food you eat and how much to discard as waste or store for future use, which is why you gain a bit of weight if you suddenly eat more than you usually do, in the same way that you feel as if you lack some energy if you eat less than you usually do. The same effect (a lack of energy) takes place if there’s a sudden spike in the physical activity you do, such as engaging in a brand new exercise regime or walking/running further than you usually do. In this case some exercise-specific supplements are required to maintain your body’s normal balance, such as some protein-based supplements for weight-lifters or athletes involved in sporting codes that require explosive muscle movements.
When You Experience a Loss of Appetite
A loss of appetite in a sense goes back to underlying health issues in that your body is sort of switches off your desire and instinct to ingest something which is specifically or potentially causing some sort of illness or damage to its normal functionality. That’s why doctors prescribe supplements such as multivitamins for patients with a loss of appetite as one of their symptoms, while they try to isolate and treat the root medical issue.
