Boosted Energy with Carlson's Pro-Rite Capsules

I've been incorporating Carlson's Pro-Rite Free-Form L-Proline & L-Lysine into my daily routine for a while now, and I can confidently say it's made a noticeable difference. The vegetarian capsules are easy to swallow, and I appreciate that they're free of artificial preservatives and unnecessary fillers. Over the past few weeks, I've felt an increase in my overall energy and vitality. While it's essential to manage expectations with any supplement and know that everyone's body reacts differently, this particular combination of L-Proline & L-Lysine has been beneficial for me. I'd recommend giving it a try, especially if you're looking for a clean, well-sourced supplement to support your health.

I love this supplement and I take it daily since I see the benefits of it on my muscle and energy recovery after intense training. The size and taste is okay. My diet is focused on sufficient protein intake so I see this supplement as a nice addition to it.

The essential amino for collagen

Verified purchase

Proline and lysine are amino acids, which are the building blocks of proteins. They play essential roles in various biological processes. 1. **Proline:** - **Function:** Proline is unique among amino acids due to its cyclic structure. It plays a crucial role in protein structure, stabilizing the three-dimensional structure of proteins and peptides. - **Usage:** Often found in collagen, the main structural protein in connective tissues like skin, tendons, and bones. Proline is also involved in the synthesis of other proteins and important for maintaining the integrity of various bodily tissues. 2. **Lysine:** - **Function:** Lysine is an essential amino acid, meaning the body cannot produce it, and it must be obtained from the diet. It plays a key role in protein synthesis, enzyme production, and the absorption of calcium. - **Usage:** Lysine is often involved in the formation of collagen, muscle tissue maintenance, immune system support, and the production of certain hormones, enzymes, and antibodies. It also plays a role in the absorption of iron and the formation of carnitine, a molecule involved in energy production. In summary, both proline and lysine are important for the structural integrity of proteins, with proline having a unique role in stabilizing protein structures, especially in connective tissues like collagen, and lysine playing a critical role in various physiological processes, including protein synthesis and immune function.

Отлично!

Verified purchase

It is very convenient that the amino acids are combined in one place. The disadvantage is that the doses in a capsule are low and to reach the optimum you have to take 8 tablets.

It’s just amazing

Verified purchase

I didn’t know that this can help me so quick! I was looking for a collagen, and I checked up all the information about how to use it, where to get it. So this quality is so good, size is perfect and package definitely protects capsules from the day light which will help to stay useful.

Great Combo

Verified purchase

Very good for your heart and all muscles. Good composition of ingredients and easy to take. I have both amino acids in powder form to put into smoothies but when you don't have time this is a great alternative. Price is good, no taste and good quality. Also good for the liver.
