Not all supplements are necessary. Sadly, some of them are not good, but it is still highly common in the bodybuilding world. Find out the 5 worst supplements everyone takes for muscle growth.
Jeff Nippard decided to shine a light on supplements that would be best to avoid.
Jeff Nippard is a natural professional bodybuilder and fitness coach who shares tips and training programs on his YouTube channel. In the following paragraphs, he talked about the 5 worst supplements everyone takes for muscle growth.
Nippard explains that these supplements are bad because it is not backed by scientific evidence if people want to lose weight or increase their muscle mass.
Worst Supplements Everyone Takes For Muscle Growth
1. Testosterone Boosters
A study from 2020 analysed the top 5 testosterone boosters sold on Amazon.com and it immediately saw some red flags. For starters, three of them did not specify proper dosing, so you don’t really know how much of each ingredient is in the product.
And from the ingredient list they had, half of them have zero human studies showing a positive effect on muscle growth. Other 3 ingredients had few studies showing a positive effect, but overwhelmingly more studies said there is no effect whatsoever for humans.
Turkesterone is one of the newest supplements available on the market. In short, turkesterone is to animals and plans what testosterone is to humans, so many people assumed (including scientists) that consuming turkesterone could help build more muscle.
Still today there is not a study to prove its benefits and there are serious quality control issues with these products.
BCAAs are supplements with leucine, isoleucine and valine. But taking these three is not that important to build muscle because you actually need all 9 essential amino acids to build muscle.
“So taking leucine without all the other essential amino acids would be like turning the key to your car without any gas in it,” Nippard says.
4. Fat Burners
Fat burners claim to have one of two paths to achieve your goals: it makes you eat less, or it increases your calorie expenditure. In reality, that doesn’t happen.
A recent meta-analysis stated that, overall, “there was no indication that the inclusion of fat burners and thermogenic dietary supplements was any more effective than exercise or a combination of diet and exercise.”
Why is beta-alanine on the list of worst supplements everyone takes for muscle growth? Beta-alanine works, but not for typical resistance training. It helps people to keep pushing longer, which sounds good on paper, but if you short sets (8-12) then beta-alanine has no effect.
A study showed that beta-alanine works for exercises lasting 1-4 minutes and didn’t do anything for exercises lasting less than 60 seconds. In short, sets under 20 or 30 reps will get no benefit from beta-alanine supplementation.
