A very good supplement that supports a healthy metabolism. I've been taking it for my mother several times now to support her cardiovascular and nervous systems. It gives her more energy, maintains her well-being, and strengthens her bones.

High-quality complex of B vitamins
Verified Purchase
Thorne is one of my favorite brands; I've been familiar with their products for a long time and am always pleased with the quality. I've been taking this complex for a while now—I like that it contains several B vitamins in one capsule. They're important for normal nervous system function, energy metabolism, and overall well-being. It's convenient to take, so it's a great everyday option for me.

I recently started taking Thorne's Methyl-Guard Plus® supplement and wanted to share my experience. Firstly, the package contains 90 capsules, making it convenient for long-term use. I chose this supplement because of its unique formula, which includes methylated forms of B vitamins such as B6, B12, and folate. This is especially important for people with certain genetic predispositions that may make it difficult to metabolize the regular forms of these vitamins. After several weeks of taking it, I noticed positive changes in my well-being. My concentration and energy levels improved, as well as an overall sense of well-being. I feel more focused and less tired throughout the day. The capsules are easy to swallow, and I haven't had any side effects, which is a big plus. I also appreciate that Thorne maintains high quality standards and uses only pure ingredients without added artificial colors or preservatives. Overall, I am very pleased with Thorne's Methyl-Guard Plus® supplement. It's an excellent supplement for supporting methylation and overall health. I recommend this to anyone looking for a quality supplement to improve their B vitamin levels!

Thorne's comprehensive, high-quality support
Verified Purchase
The capsules are medium-sized and easy to swallow. The formula is well-thought-out, and the dosages are balanced. I take them in courses—I feel a slight boost in overall tone, although the effects aren't pronounced. Thorne usually has high-quality formulas, and everything here looks neat and reliable.

Good

We are taking it not for the first time! It was prescribed by a gynecologist. There are breakdowns in the folate cycle, so this complex perfectly covers the deficiencies in vitamins of group B, due to the correct forms. We will drink courses about twice a year!
