What's the best protein to keep and gain muscle when you're older?

It would be helpful to have tips on how to better absorb protein. Older adults don't always benefit from the protein we eat. I'm 63 years old with a very healthy moderately-high-protein diet, plus I take 10 grams a day free form amino acids. My latest blood work showed low Total Protein, even though kidneys and liver seem to be healthy. I also take betaine HCl and enzymes at each meal.

Please do a review/test on OWYN protein powder shakes. Thank you

When you state that "Plant-based foods can also provide protein and build muscle, although, individually they might not provide the optimum ratio of amino acids," you are dangerously close to repeating the now debunked myth that vegans and vegetarians must "combine" various proteins to get a "complete" protein profile. Credible studies exist on this topic:

I am a 69 year old man (6' 3", 185 lbs), and strive to eat a plant-based diet except for fish and occasional eggs. I consume 90-110 grams of protein a day; much of it from whole foods but with some augmentation from Garden of Life Organic Plant Based Protein (no financial interest). I also engage in relatively heavy weight training 3 days a week. I am easily able to maintain strength and considerable muscle mass. I consider the regimine a fountain of youth and highly recommend it to older folks.

as i understand it, it doesn't matter if you have all the essential amino acids at once as long as you get them all and a whole food plant-based diet provides them all. btw, and soy provides all the essential amino acids.

How about the bone broth protein powders?

Do you test protein powders that are sold directly from distributors like Usana, Shakeology, Shaklee, Plexus, Isagenix etc.?

For many years I have been making my breakfast smoothie with Natures Plus Unsweetened Gluten Free High Protein Energy Meal. All ingredients and digestive enzymes are listed. I am pre-diabetic but adding some frozen blueberries and small medium banana with CocoVia dark chocolate powder make a great shake. I purchase the powder from VitaCost.

I am also interested in research into "Vital Proteins" Collagen powders.

I like to take Swanson Vitamin's organic pea protein powder along with its Green Max mixed in. They are inexpensive and don't taste bad or overly sweet like other brands. I use a small, inexpensive, high powered battery powered whisk from Amazon that takes double A batteries to whip it up quickly.

Please do a report on Collagen and Protein powders. Some Brands are Bulletproof, Multi-Collagen, Vital Proteins, Great Lakes etc. Thank you.

Here's a good resource to double check your protein powder.

Please test protein powders sold by Dr. Joseph Mercola, by Kathy Smith and protein powders under a "Tera's Whey" brand and a brand called "Naked" whey. Thank you.

Thanks for all you do, ConsumerLab !
May i request you check out Whole Foods white-label (365 Everyday Value) "Whey Protein Powder" - i typically buy the Vanilla - it's inexpensive, has limited carbs, and contains very few ingredients overall.

thanks from a long time subscriber

Please test NutraBio whey protein isolate

I liked your last protein powder review. I would like to see more whey/casein blends included in your review. The blends keep me full for hours where as just whey alone only lasts an hour or so with me.If it is just a whey alone product I mix Casein whey product with it.
I would like to see reviewed by you are BSN Syntha 6 and Six Star Whey Protein Triple Chocolate.
Casein alone varieties are: Six Star Casein Protein and Precision Engineered 100% Micellar Casein.
Thank you for all the great work you do.

Dymatize is my favorite and the make an ISO whey, plus a slow digesting casein. Would love to see them tested.

Please include "Hydro-Pro" Advanced Hydrolyzed-Isolate Whey Protein Formula made by EVOchem Nutrition in your test.

I use both Youngevity Fitshake, and human Protein 40 and would appreciate testing either/both.

HEMP PROTEIN POWDER BY NUTIVA IS MY CURIOSITY. I USE IT DAILY AND HOPE THAT IT CHECKS ALL BOXES ON SAFETY. I LOVE & TRUST NUTIVA FOR ALL OF MY SUPPLEMENT ITEMS (BAKING PRODUCTS, NUTS SEEDS ETC) AND HOPE THAT THEY ARE AS CLEAN FROM TOXINS AS THEY CLAIM TO BE.

Please also test Garden of Life's Raw Organic Protein, Unflavored, Unsweetened powder.

Hello, when you test protein powders can you please test Now protein isolate unflavored and Pro Mix Isolate, as well as a variety of other unflavored isolates. Also, can you review if there is any benefit to grass-fed whey and compare grass fed isolate to concentrate to non-grass fed whey. Also, is there any efficacy to cold-processed isolate or concentrate over other types. Thanks.
