How to Increase Muscle Growth Naturally

By Brendan Brazier

The most efficient way to achieve your fitness goals is through effective training combined with optimal nutrition. As a strength athlete you may be considering a regimen of supplements that claim to help you grow bigger muscles and get more pump. Some of these supplements may be inefficient or ineffective, while others are simply dangerous. However, there are nutrients found in whole plant-based foods that can help to support muscle growth—and increase your pump, naturally. Adding in whole food sources of nitric oxide, L-arginine and branched chain amino acids to your diet can help increase your potential for improving endurance and increasing muscle growth naturally.


Branched-chain amino acids (BCAAs) consist of three essential amino acids—isoleucine, leucine and valine, which must be consumed through what we eat because our bodies are not capable of creating them. Without replacement of BCAAs before and after exercise, muscle damage may occur and protein synthesis may be inhibited.4 BCAAs have traditionally been used in an ideal ratio of 2:1:1 of leucine, isoleucine and valine. Leucine in particular has the capacity to stimulate muscle protein syntheses and has gained more attention for its ability for muscle growth and muscular endurance.5

The dosage of a BCAA supplement is determined by body mass. Five grams of BCAAs is often sufficient to produce a benefit.

Foods with BCAAs

You can find BCAAs in Brazil nuts, pumpkins seeds, lima beans, chickpeas, cashew nuts, and hemp protein. You can also buy a supplement in your natural health food store, or look for a plant-based protein powders that includes BCAAs, such as Vega® Sport Premium Protein.

Nitric Oxide

Nitric oxide (NO) is a gas that is used to dilate your blood vessels.  This increases blood flow and nutrient delivery to your muscles, while also increasing waste removal from your muscles. With increased blood flow and delivery of nutrients and oxygen to the muscle, your body can produce a better pump, with more force, when lifting weights. It can also aid in increased recovery time and muscle growth. While there is little research supporting the effects of adding a NO supplement to enhance your performance, it is plausible that adding NO-forming foods to you diet may improve muscle pump when lifting weights.

Foods with Nitric Oxide

One way to supplement NO through food is with beetroot juice. Beets contain nitrates and antioxidants that are beneficial on our overall health. The nitrates in beet juice are converted into nitric oxide which has the potential to increase blood flow.1 Consider adding beet juice to a smoothie or hydrating beverage to reap the benefits of NO on muscle pump.


Exercise naturally stimulates growth hormone release, which is important for muscular strength gains. The amino acid L-arginine has also been shown to stimulate growth hormone release while our bodies are in a resting state.2 Arginine is an amino acid that is readily converted to nitric oxide in your body. Dietary supplementation of arginine has also been shown to normalize the hormonal stress response, to lower the amounts of cortisol you produce.3

Foods with L-arginine


  • Coconut
  • Pecans
  • Cashews
  • Walnuts
  • Almonds
  • Brazil nuts
  • Hazelnuts
  • Pinenuts


  • Pumpkin
  • Sesame
  • Sunflower
