During intense training, your muscles go through, they are subject to an overproduction of free radicals which is what causes muscle recovery to be hindered and you from reaching your strength capacity.

It is actually the free radicals that cause oxidative damage to your muscle cells and this is why taking antioxidants or using IV therapy will help reduce soreness and get you back to full strength quicker.

What Actually Happens to Your Muscles During Hard Training

Hard workout leaves microscopic cracks in muscle, and that’s intentional. In fact, the damage causes the repair mechanisms to get to work, which eventually leads to larger and stronger muscles. But, of course, recovery can only happen after some damage. Repair takes time and inflammation is a normal part of that. If you feel your muscles aching about a day after you had a really heavy training session, or so-called delayed onset muscle soreness, that is just a physical manifestation of the whole process.

On top of tissue trauma, the body also suffers a metabolic hit.

The rapid consumption of energy by muscles produces leakage of reactive oxygen species, which are basically very unstable molecules that can steal electrons from anything close, e.g. the fatty envelopes of your muscle cell membranes.

Free radicals damage your cell’s components – proteins, fat, and mitochondria if left uncontrolled. That can even slow down cell repair and other vital metabolic processes your body is trying to carry to make you recover. Scientists have found a correlation between levels of oxidation stress and muscle pain and low ability to train the day after, meaning that higher oxidation means more aches and less ability to exert.

The main defences your body has against the attack of free radicals are its own antioxidant enzymes and the by-products it creates inside itself. But, the natural mechanisms are more able to keep up if a person is well rested and well fed. When free radical production exceeds your body’s internal defences and dietary antioxidants become an essential part, it”s either because training load is increasing, recovery is getting shorter, or your diet is not enough.

Which Antioxidants Matter Most for Recovery

Vitamin E is among the most important vitamins because it is fat- soluble and embeds right in the cell membrane where exercise-induced oxidative damage tends to happen. By positioning itself within the membrane, it intercepts free radicals just the slightest moment before they wreak havoc by attacking the fat in muscle cells surrounding and inside the muscle cells.

This particular membrane-level action is precisely what a muscle cell undergoing its recovery phase calls for: vitamin E, So being most often linked with training.

Vitamin C works very much to vitamin E’s disadvantage in aqueous parts of the cell, whereas the regeneration of used-up vitamin E is also a part of its role.

That’s why both work very much as a team of two without even being competitors. The focus was not only on classic vitamins, but also plant polyphenols from tart cherry, beetroot, and various berries, which show promising results in decreasing soreness and raising inflammation markers after hard workouts. The most studied among them – tart cherry – was tested on a range of people from runners to strength athletes with most of the results showing that with strength recovery comes faster and the amount of soreness is lower.

The form of vitamin E matters more than most people realise. Natural vitamin E isn’t a single molecule but a family of eight, four tocopherols and four tocotrienols, and cheap supplements often contain only synthetic alpha-tocopherol. A full-spectrum product that supplies the range of tocopherols tends to reflect how the nutrient actually appears in food, which is part of why something like Unique E mixed tocopherols is the kind of option people reach for when they want more than isolated synthetic alpha-tocopherol. Checking whether a label says natural (d-alpha) versus synthetic (dl-alpha) is a quick way to judge quality.

The Timing Question That Changes Everything

So that’s where a lot of well-intentioned athletes make the mistake.

That is because the production of free radicals after a workout is part of the signal that leads cells to adaptations; So, taking high-dose antioxidants around every session might actually interfere with some of the training benefits you are so dedicated to achieving.

In fact, several studies have concluded that very high levels of supplements like vitamin C and E taken around the workouts can disrupt endurance and mitochondrial development.

This is not at all suggesting that antioxidants are harmful for an athlete but that taking a megadose of antioxidants before every workout might not be the wise move. In fact, when you get your antioxidants mainly through your meals – such as a mix of different fruits vegetables, nuts and seeds – not only do the levels of different antioxidant compounds at one time fall below those of single ones, but you recover without suppressing that signal from oxidation which high-dose isolated supplements can do. Very few are whole foods sources that cause the extreme concentrations that result in problems.
