The 12 Best Supplements, According to a Dietitian

Collagen is a popular supplement for those looking to improve joint, skin, and bone health. While collagen supplements vary in the amount and types of collagen they provide, most people can tolerate collagen well, and is generally considered a safe supplement if you don’t have a food allergy to fish, shellfish, or eggs or avoid eating animal-based foods.

If you want to add collagen powder, we recommend Vital Proteins Collagen Peptides, which provides 20 grams of collagen per two-scoop serving. It’s sourced from grass-fed, pasture-raised cows kept in alignment with the Global Animal Partnership’s five-step animal welfare rating standard, so you can feel good knowing you’re getting a high-quality and thoughtfully sourced product.

In addition to grass-fed bovine collagen, Vital Proteins adds vitamin C and hyaluronic acid to their powder. These two nutrients can be helpful as the body uses them for collagen synthesis.11

While collagen contributes to your overall protein intake, note it is not considered a complete source of protein because it is lacking in one of the essential amino acids, tryptophan. Because of this, it’s important to avoid relying on collagen supplements as a primary source of protein in the diet.12

The tasteless powder is soluble in hot or cold liquids, so it can easily be added to your coffee, smoothies, or other beverages.

Getting enough fiber is important for many reasons, but unfortunately, many people don’t get enough fiber in their diet. Foods high in fiber include fruits, vegetables, whole grains, legumes, nuts, and seeds. If you don’t get enough of these foods or have a health condition that can benefit from added fiber, a fiber supplement may be recommended for you.

NOW Psyllium Husk Caps are our top pick for the best fiber supplement due to their effectiveness and quality. Psyllium husk is a fiber supplement that’s known to aid in digestion and may improve constipation. Additionally, research shows psyllium husk can help lower cholesterol in those with high cholesterol levels.

NOW Psyllium Husk Caps are third-party tested so that you can feel confident in their purity and potency. A potential downside to the NOW Psyllium Husk Caps is the requirement to take three capsules multiple times per day with 8 ounces of water. The manufacturer recommends two to three doses per day for maximum effectiveness, but a healthcare professional can give individualized recommended dosing.
