Sidelined. A reality that no runner wants to face, but so many of us have come up against it. Sometimes we get weeks of warning signs. Other times, injuries happen in an instant. No matter the cause, staring face-to-face with an injury comes with the realization that recovery will take time and patience, rest, and rehab.
Nutrition may not be top of mind for an injured runner, however, there are several nutrients that can complement your rehab program and get you back out there a little faster.
Let’s start with the big one - protein. Protein is made up of amino acids, which are the building blocks of our body’s cells, tissues, and muscles. Protein supports both muscle repair and maintenance and a reduction in protein intake can increase muscle loss and, therefore, strength 
One of the most common mistakes runners make is to slash calorie (and protein) intake during periods of injury. While you may need a few less calories than usual, you still need to get enough fuel to support the energy demands of healing. This is especially true for protein because of its role in building new tissue and stimulating muscle protein synthesis.
Moreover, consuming enough protein while you're injured may help prevent muscle loss, maintain strength and improve weight management 
Aim for 2 - 2.5g protein/kg/day spread throughout the day, with no more than 30-40g protein per meal or snack [ 1 2 
2]. Research suggests that our bodies can only utilize 20-40g protein for muscle synthesis at any one time
Eat a variety of protein-rich whole foods such as skinless poultry, low mercury seafood, Greek yogurt, beans, tofu, and lean meat. Fill in the gaps with a high-quality whey or plant protein if you're struggling to meet your protein needs.
Every injury comes with inflammation. Inflammation is typically highest in the first 48 hours after the injury occurs, although it varies depending on the type of injury. And while extreme inflammation should subside after a few days, lingering inflammation can impede recovery. This is where omega-3 fatty acid supplementation (or consuming fatty fish several times a week) can offer support.
Omega-3s are polyunsaturated fats that block inflammatory markers and fight inflammation. Your body can not make omega-3s - which include EPA (eicosapentaenoic acid), DPA (docosahexaenoic acid), and ALA (alpha-linolenic acid) - so getting them through your diet or supplementation is important regardless of injury status. (Read more about the benefits of omega-3 fats here).
Emerging research suggests that omega-3 supplementation may play a role in both recovery and injury prevention in athletes. Specifically, omega-3 fats seem to counter muscle loss by increasing muscle synthesis [3, 4]
However, there’s a catch. Omega-3 supplementation may impair wound healing so if you’re dealing with nasty scrapes and scratches, you might want to give this one a miss (albeit temporarily).
Evidence to date indicates that 1.5-2g/day of EPA and DHA may be helpful for endurance, recovery, and adaptation to training.
A fish oil or algal supplement is generally the easiest way to get 1.5-2g/day of EPA and DHA, however, low-mercury fatty fish such as salmon, trout, sardines, and herring, can also help round out your omega-3 intake (and meet protein needs).
Joint stiffness and pain are common among runners, and can be exacerbated by hard training cycles, jumps in mileage, or simply getting older. Glucosamine and chondroitin are natural compounds found in joints and cartilage and may help ease joint pain and slow joint degradation, especially in knees and hips [5 6]
The recommended dosage for glucosamine sulfate is 300-500mg 3x/day for a total of 900-1500mg/day. Alternatively, up to 3000mg glucosamine sulfate salts/day can be taken as a single dose 
For chondroitin, a single or divided dose of 1000-1200mg/day appears to help most helpful for joint issues 
Supplementation is the only option for consuming adequate amounts of glucosamine and chondroitin for joint health. Glucosamine is typically harvested from shellfish, while chondroitin is usually produced synthetically.
Calcium and vitamin D go hand-in-hand and are especially important if you have a bone-related injury. Ninety-nine percent of calcium in our body can be found in our bones and teeth, but it also plays an important role in regulating muscle contractions, nerve conduction, and blood clotting 
Vitamin D is a fat-soluble vitamin that increases calcium absorption in the gut and is therefore vital for a strong skeleton  
. Adequate vitamin D is also essential for normal immune function, reducing inflammation and muscle health, and may even help prevent injuries(!)
While daily calcium needs can be achieved through diet, vitamin D is harder to come by and almost everyone can benefit from supplemental vitamin D (unless you live at the equator).
The recommended dietary allowances for calcium are 
1000mg/day (age 19-50)
1000mg/day (age 19-70)
For Vitamin D, the recommended daily allowance for both men and women 19-70 years old is 15 mcg/day (600 - 800IU) but some evidence suggests that 50mcg or more (2000IU+) may be helpful for certain people 
Before you go all-in on calcium supplements, it’s worthwhile assessing if you get (or can get) adequate calcium from dietary sources including yogurt/milk/cheese, canned salmon with bones, canned sardines, broccoli & kale, and fortified foods including juice, cereals and plant-based milk 
If you need a supplement, look for calcium citrate and take in divided doses to maximize absorption. Take iron and calcium supplements at separate times since iron interferes with calcium absorption and vice versa.
Vitamin D can be synthesized in our skin from cholesterol and exposure to sunlight, however, few of us get enough sun all year round to rely solely on endogenous vitamin D. Vitamin D is only found in a few foods such as cod liver oil, salmon, and fortified milk, and supplemental vitamin D3 is the best option for many.
Turmeric is a powerful anti-inflammatory agent and has been used for centuries as a traditional remedy for everything from digestive issues to skin health  
. This bright yellow spice contains many compounds, however, a polyphenol called curcumin is largely responsible for its inflammation-fighting benefits
Studies show that curcumin may be helpful for alleviating pain and inflammation in people with osteoarthritis, a common issue among runners (years of pounding pavement can be tough on joints) 
Furthermore, a handful of trials have shown that curcumin may be beneficial for fighting inflammation and reducing muscle soreness after exercise, although this research is still in its early stages 
1000mg/day of curcumin for 8-12 weeks seems to be most effective for relieving osteoarthritis pain and inflammation 
For reducing muscle soreness, 400mg-2000mg curcumin/day in the days leading up to and following exercise appears to be most effective 
Interestingly, taking curcumin together with black pepper has been shown to increase the bioavailability of curcumin by up to 2000% which is a major plus for a compound that has poor bioavailability 
Adding turmeric to dishes at home can enhance flavor and color, however, it’s unlikely to provide enough curcumin to kick joint pain and inflammation. Curcumin supplementation is generally the easiest and most effective way for runners to reap the joint and muscle benefits.
Nutrition tactics such as consuming adequate protein and adding in a few strategic supplements can be beneficial for runners recovering from an injury - but they shouldn’t be the only things that you’re doing to help your body repair. Rest, rehab, adequate calories and a diversity of minimally-processed whole foods should also be part of your recovery plan. No runner likes to be sidelined, however, a little extra effort (and patience) now can save you a whole lot of pain and heartache later.
As always, check with your doctor before starting supplements if you have a pre-existing condition.
